LINER STRENGTH PREVENTS STORM POLLUTION

C IPP lining manufacturers and companies have, almost since the technology was invented, laid claim to just how strong their liner materials are once installed. To some clients this has been seen as just ‘marketing’. Well not any more.

Some seven years ago Insituform Technologies Ltd. (ITL) undertook a pipeline rehabilitation project on the Isle of Man using a 4.5 mm thick standard, needle felt, resin impregnated CIPP liner to rehabilitate a deteriorated 225 mm diameter, clay, foul sewage pipe, part of which ran under the river bed close to the village of Laxey, located on the east coast of the island. Until recently, the pipeline operated as expected, passing flows out to sea off the harbour.

A major storm system passing over Isle of Man produced major rainfall which caused the Laxey River to flow extremely fast. These flows were sufficient to scour the river bed to the point where the clay pipe and its concrete surround were exposed to the torrent at the point where it crossed the river. Cobbles and boulders brought down the river by the torrent crashed into the exposed pipe and its concrete surround, smashing it completely.

This was where the ITL Insituform® CIPP liner came into its own. Whilst the original concrete casing and the clay pipe were completely destroyed where it was exposed to the worst of the river flow, the standard Insituform® CIPP liner held fast without noticeable damage. Not only did the strength of the seven-year old liner allow the pipeline to continue operating despite the terrible conditions, the fact that it did prevented a major pollution problem in the river. If the pipe had failed completely, foul water flows would have spilled directly into the river water. The polluting flows would most likely have continued for sometime as the pipe break would not have been detected until the river flows had subsided sufficiently to expose the breach.

Commenting on the performance of the liner under the circumstances, Steve Knowles, of the Department of Transport for the IOM said: “Had this clay pipe not been lined, we would have suf-fered a major pollution event during the flows caused by the storm. As it was, thankfully, this did not happen. To repair the pipeline, since we had no need to install over pumping we saved significant time and effort in the works to bring the pipeline back to a fit-for-purpose state of repair. The continuing presence of the liner also now reassures us that we have that little extra level of security on the pipeline at the river crossing point should anything similar happen in the future.”

For ITL, John Beech, Business Development Manager commented: “We have always said that our liners were good even though perhaps some people thought this was just marketing talk. Now

everyone knows it is not. Whilst we would not wish to see our clients put into a position where our products are tested in circumstances such as those recently found at Laxey, it is instances of this kind and the performance of the liners in such extreme conditions that reinforce our confidence in our products.” Website: www.insituform.co.uk

EARTH DISPLACEMENT MOLE SUPPLY CONTRACT RENEWED BY NATIONAL GRID

F ollowing an exhaustive tender bid procedure through the Achilles UVDB Scheme, National Grid has awarded its Earth Displacement Mole supply contract to TT-UK, part of the International TT Group of Companies for its GRUNDOMAT machines.

The award of this supply contract was made after technical, commercial and quality assessments of two leading moling manufacturers. Whole life cost factors were taken into account and after careful consideration the GRUNDOMAT Earth Displacement Mole as chosen.

TT-UK manufactures and supplies a wide range of Trenchless Technology equipment, for the most cost effective method of installing/replacing existing pipes/cables underground without associated traffic disruption and environmental impact. Website: www.tt-uk.com

GIANTS PREPARE THE WAY FOR SUBTERRANEAN LIFELINES

H errenknecht AG took part in the German-Chinese Esplanade event which took place in the Chinese city of Wuhan from October 23 to 31, 2009. The Esplanade forms part of the event series “Germany and China - Moving ahead together”. Under the joint patronage of Germany’s Federal President Horst Köhler and China’s President Hu Jintao, Germany presented innovative solutions to meet the challenges of ongoing urbanisation. Herrenknecht showed visitors the contribution that high-quality tunnelling machines are making towards achieving sustainable urban development and mobility. The company supports the Esplanade in Wuhan as a stage partner, as it did three times before in Nanjing, Chongqing and Guangzhou.

Rapidly growing megacities and overused traffic and transportation systems are concomitant effects of economic growth and urbanisation in China. Only an infrastructure which grows together with the population can guarantee the quality of life in the cities. Therefore, the extension and modernisation of traffic tunnels and efficient supply and disposal systems are a top priority in the Peoples’ Republic.

With mechanised tunnelling technology Herrenknecht is providing the key technology ‘made in Germany’ to create new links within densely built-up cities. Tunnel construction takes place almost completely underground, without noise and impact on aboveground traffic and people. At the same time, mechanised tunnelling is faster, more environmentally friendly and safer for tunnel workers than conventional procedures (for example drill & blast tunnelling).

Mechanised tunnelling technology from Herrenknecht is opening up new transport and supply channels for several large cities in China. The new construction of Wuhan’s subway line 2 is being carried out using Herrenknecht tunnel boring machines. Seven machines are excavating almost 17 km of tunnel.

Five Earth Pressure Balance Shields are crossing beneath inner-city areas and two Mixshields, specialised in multi-layered, highly water-bearing ground, will cross beneath the Yangtze River. In Guangzhou, the subway network has been constantly extended over the past years. Of a total of approximately 140 km of subway tunnel which are to be produced using Herrenknecht tunnel boring machines (EPB Shields and Mixshields) with diameters of 6.25 m, more than 105 km have been excavated since 2000.

Herrenknecht supplied the two largest tunnel boring machines in the world each with a diameter of 15.43 m for two gigantic traffic tunnels in Shanghai. The two colossal machines, with a weight of 2,300 t and each with a length of 125 m, crossed beneath the Yangtze River at a depth of down to 65 m. The two tubes of the ‘Shanghai Yangtze Under River Tunnel’ provide a connection for the inhabitants of the nearby river island Changxing to the Shanghai city district of Pudong. The two breakthroughs in May and September 2008 respectively, set an international milestone in mechanised tunnelling due to the extremely large tunnel profiles and the corresponding high requirements regarding efficiency and safety. The project also set new standards with respect to the construction time. The two tunnels, each almost 7.5 km long, were completed after only 20 months, some 10 and 12 months faster than scheduled. The completion of tunnelling work ahead of schedule provides the ideal conditions to open the tunnel on time for the 2010 World Exhibition in Shanghai.

PEACE OF MIND FOR CHRISTMAS AFTER NEW DRAINS ARE COMPLETED EARLY

M ajor work to enlarge drains under Chelsea, London , UK and protect more than 100 homes from being flooded with sewage has been completed four months ahead of schedule.

The £6.1m scheme includes 540 m of new sewers, including one 280 m long, 1.5 m diameter tunnel.

The scheme will protect 109 homes around Norland Square and Holland Road, in W11, from the misery of sewer flooding.

London’s sewerage network was built in the 1800s. Since then the city’s population has more than doubled in size, meaning more sewage going down the same old pipes, which is why Thames Water is building new ones in the worst-affected spots like Norland Square.

Prunella Khalawan, Thames Water’s project manager for Norland Square said: “Our customers’ top priority is protecting their properties from the risk of sewer flooding, which means it is our top priority too. Finishing this work five months early means residents do not have to spend another Christmas with the dread of sewer flooding hanging over them. Residents in Kensington and Chelsea have for many years suffered with sewer flooding, as climate change brings heavier but less frequent rainfall, and population growth and increased concreting-over of green spaces puts increasing strain on the area’s ageing sewer network.” The Norland Square scheme was due to be completed in March 2010.

Councillor Nicholas Paget-Brown, Cabinet Member for Transport, Environment and Leisure at the Royal Borough of Kensington and Chelsea, said: “We are pleased that Thames Water’s ambitious project to rebuild and modernise ageing drains under Norland Square has been completed four months ahead of schedule. Sewer flooding is truly miserable so it is excellent news that Norland Square residents will have peace of mind this Christmas.”

In terms of the construction work itself, a significant part of the project was undertaken by Barhale Construction plc using microtunnelling techniques. Using shaft of between 3 m to 5.5 m diameter at an average depth of 19 m, some 242 m of new 1,500 mm diameter pipeline was installed using an Akkerman microtunnelling machine plus a further 228 m of 600 mm diameter pipeline was installed using an Iseki Unclemole.

MULTI-FORM LININGS ACROSS EUROPE

S tadtentwässerung Dresden GmbH, a subsidiary of the Saxon S t a t e C a p i t a l D r e s d e n a n d G E L S E N W A S S E R A G , i s responsible for the collection and treatment of wastewater in its area. The area, on the Elbe River, serves 500,000 inhabitants with an average water consumption of 100 l per day. Including stormwater, around 60 million m³ of wastewater is collected and treated in the Dresden-Kaditz treatment plant per year or some 120,000 m³ of wastewater on a dry day. A quick and safe discharge of this large quantity of water requires a well functioning sewer system. Parts of the network are, however, over 100 years old and constantly need to be repaired and renovated. Since 1990 Stadtentwässerung Dresden GmbH has invested €575 million in the renovation and expansion of the sewer network as well as water treatment plants.

The sewer mains were built over the last three decades of the 19th century. They run perpendicular to the Elbe and lead into collectors paralleling the river along the old and new town sides. A survey showed that the compressed concrete so-called Old Town Collector on the left side of the Elbe urgently needed to be renovated. There were several signs of damage and a safe load capacity was no longer guaranteed. The section to be renovated ran over 1.3 km through the old town quarter and along the left bank of the Elbe.

Home to the Semper Opera House, the Zwinger Palace, the Old Masters Picture Gallery, the treasure chamber of the Electors and Kings of Saxony, and other historic sites, Dresden attracts around 7 million tourists per year. The only way to ensure Dresden’s visitors had a pleasant stay was to renovate the old sewer using trenchless means, namely lining. This technique compared, to open trench installation given the construction time and inconvenience through traffic disruption, meant disruption to tourism could be kept to a minimum. The renovation costs for the sewage collector are around €7 million and construction works will be completed by the second half of 2010.

During construction works, wastewater is diverted with a DN 1200 siphon pipe with a maximum flow rate up to 1,900 l/s. It runs on supports underneath the quay so as not to hamper the Saxon steamboats and above the quay wall beyond the Augustus Bridge.

After a thorough comparison of the options available, Stadtentwässerung Dresden GmbH opted to use HOBAS NC Line® alongside other brands. With a k-value of less than 0.01 mm the smooth inner surface of the liner profiles proved to be a decisive advantage given that hydraulic requirements are met despite the slightly reduced diameter of the liner profiles. During preparations, technical details were arranged with the planning office ACI-Aquaprojekt Consult and contractors Insituform Rohrsanierungstechniken GmbH and Heinrich Lauber GmbH in Coswig. The contractors paid particular attention to meeting the required quality parameters and to technological processes. The existing pipe was first inspected and calibrated by laser scan and manually with a mould to de-

termine the exact outer dimensions of the required profiles. This was necessary to maximise the capacity of the new sewer whilst ensuring an easy installation. A precise plan including standard and short profiles and some with special oblique couplings was worked out. Because the condition of the existing sewer is categorised as Class III, the calculations were

carried out with due consideration of the special geometry and the grouting procedure. Here it proved advantageous that HOBAS NC Line® Profiles are manufactured with definable wall thicknesses, which keeps statically inconvenient imperfections to a minimum. Since the profiles are produced at the factory, there is no subsequent shrinkage that could lead to circular cracks. Because deformations due to inconsistencies in the old sewer are not transferred to the new pipe as would be the case with cured-in-place relining methods these need not be considered.

Special requirements were set out for the quality of the NC Line® Profiles. The production facility was audited for production approval. This was done by inspection, to check the quality assurance system and to see if standards were kept according to specifications. The supplied product was analyzed in addition to the assessment. The engineering office Siebert und Knippschild therefore took specimens from the construction site and checked them for given parameters.

In two separate construction stages one 520 m and one 320 m length of HOBAS NC Line® Profiles were installed with internal dimensions of 2,157 x 2,129 mm and 2,242 x 2,195 mm. The 2.35 m long HOBAS Profiles were lowered into the assembly pits by crane. With a specially built transportation vehicle the profiles were fed into the old sewer and assembled. Using special technology ensured optimum pipe transportation and installation. Finally, the new line was secured against uplift and the space between the old and new structure was grouted.

Once the project is finalised, the collector will be completely restored and should last for the next 100 years even during floods. The City’s many tourists barely notice the works beneath their feet. Pipe storage and assembly pits that are set in relatively large intervals along the route are the only evidence of the ongoing activities under the streets of Dresden’s Old Town.

RENOVATION IN STRASBOURG In a further example of lining, the reconstruction of the sewer main for the Rhine Harbour of Strasbourg was a model example of open cut and trenchless installations can be used in unison. Where the working space would have been insufficient, rehabilitation was carried out using lining utilising prefabricated GRP NC Line panels. Wherever a trench was feasible, CC-GRP Pipes were laid in an excavated trench.

The project, coordinated by the Water and Sanitation Division of the Urban Community of Strasbourg, involved the renovation of an egg shaped main of 1,400 x 1,900 mm that functions as combined sewer for domestic and industrial effluents. Some 980 m of DN 1500 CC-GRP pipe was laid in a trench at depths varying between 3 and 9 m. Over a length of some 550 m the existing egg shaped structure was lined utilising GRP NC Line panels with an internal dimension of 1,230 x 1,660 mm.

The concept and implementation of mixed installation techniques for the project was particularly innovative and pragmatic. All pipe materials were supplied by HOBAS. “We were looking for the best techno-economical compromise and this led us to selecting these techniques for this project. The performance of the two methods and the pipe material had to be taken into account while keeping environmental impact to a minimum. Trenchless installation enabled the industrial roadway to remain open for use as well as allowing us to comply with budget and safety considerations”, explained Marc Hunsinger, head of the CUS Water and Sanitation Networks department.

The project was coordinated by a consortium where SMCE Réha was responsible for the trenchless section and EJL Alsace for the open cut section.

profiles.


The sewer main that was relined has a curved section and therefore required the use of panels in different lengths varying from 1 to 2.35 m. These were inserted in the main with the help of a trolley. They were fitted together with a hydraulic jack with the panels being held in place with wooden wedges and finally fixed into position by grouting of the annulus.

For structural rehabilitation, the 25 mm thick NC Line panel walls have been calculated to ensure the optimum performance of the new pipeline. This system not only transfers vertical loads (ground and heavy industrial traffic) but also, and more importantly, withstands aggressive substances from effluents from the agronomical industrial plants which have pH levels ranging from 1 to 10. The sewer’s leak tightness is guaranteed by the use of EPDM rubber seal integrated in each joint connection. “The structure of the masonry sewer was very weak due to constant heavy loads from lorries. Furthermore, its crown has suffered because of corrosive exhaust emissions”, stated Laurent Gerber, Managing Director of SMCE Réha.

The sections relined with GRP panels show high structural and mechanical strength, the flow rate is now considerably higher, and the new material is corrosion as well as abrasion resistant guaranteeing durability for at least 50 years.

Mr. Laurent Gerber added: “Trenchless rehabilitation was a good alternative installation method that allowed us to keep existing trees and moreover ensured open access to the industries of Strasbourg’s harbour. The lining only required three access pits over the 550 m long stretch that was rehabilitated and therefore kept disruption of a well frequented road to a minimum.”

The simultaneously excavated section called for special equipment as emphasised by Jean-Claude Bouvard, director of the EJL Fergersheim branch: “We deployed heavy machinery and a lot of manpower for the installation of the new sewer. For the maximum depth of 9 m we used high

tonnage compact excavator types 944, 934 and 924 from Liebherr as well as heavy-duty double slide trench shields. The DN 1500 CC-GRP HOBAS Pipes weigh only 365 kg/m, each standard unit being 6 m long. The therefore comparably light weight at the given diameter, the pipe length and mounted push-to-fit joints made handling easy. Besides, this was the first GRP project for the EJL construction team and we are delighted to see that all went well. In line with our commitment to environmental protection the excavated soil could be used as backfill material. Only the pipe bedding materials were newly supplied.” Completing the system and in addition to the pipes, fifteen prefabricated HOBAS CC-GRP DN 1500 x DN 1000 tangential manholes have been installed for the open trench section. These special components are equipped with GRP couplings which connect to the standard centrifugally cast GRP pipes. Website: www.hobas.com

TRENCHLESS OPTION KEEPS PRODUCTION ROLLING AT KOMATSU UK

I nvestigations of the foul sewer system at Komatsu UK Ltd in Birtley, Chester-le- Street, County Durham, UK, the company’s European manufacturing plant for the production of crawler hydraulic excavators for its European market, showed that the existing Pitch Fibre pipe network was in serious need of renovation or replacement.

CCTV survey of the Pitch Fibre pipes, which were first installed in the early 1960’s, highlighted that they were badly delaminated and deformed and that there were holes in the pipe wall running over the full 380 m length in question. In one place the pipe was closed with only just enough room to pass a jetting hose through it. According to Dave Bushby managing director of Keep Trenchless Technologies Ltd (KTTL), formerly Environmental Services North East Ltd, the company employed by Komatsu as consulting engineer and contractor to survey the site, plan the necessary works and undertake the pipe repairs: “I was horrified when I saw the state of the pipe. This is possibly one of the most deformed pipelines I have yet come across.”

OPTIONS AND LIMITATIONS Komatsu’s production schedules meant that there was limited access granted to the site to complete the project in terms of both timescale and equipment space. The failure of the foul waste pipe, its physical location on site and the potential affect this would have on manufacturing output was a major concern to the Komatsu’s management.

After careful consideration of the options available, KTTL decided that open cutting the pipeline to affect repair was simply not practical. If this conventional method of repair had been adopted to replace the failed pipe Komatsu’s production would definitely have been adversely effected. This was because the location of the pipe was right in the centre of the main production area. Excavation would have required the removal of a 15 mm thick mild steel floor. This would be followed by excavation of a 500 mm thick reinforced concrete slab and further excavation through rock and shale ground to reach the drain depth, which averaged about 3 m. This was confirmed using core sampling.

The estimated time for this traditional method of pipe replacement was around 18 weeks. The cost of the open cut option was also in the region of £750,000.

In addition to the difficulties of digging down within the production plant there were also other considerations to be taken into account. Within the site there were three major supporting walls around which work would have to take place, the undermining of which could have influenced the structural integrity of the production plant building.

As it was, Komatsu was looking for an option that would not only have minimal affect on production but also be able to be completed in just 1 week.

Other site investigations also showed that there was no alternative route along which a new pipeline could be laid that would effectively drain the site as required. So the existing route of the

pipe had to be maintained. BEROLINA-LINER OPTION Having considered the various aspects of the project it was decided that the best option for rehabilitation of the drainage system under the Komatsu plant would be re-rounding of the existing pipe, where necessary, followed by the insertion of a structural lining. The size, type and condition of the existing pipe as well as

access limitations and the timeframe required for the work meant that a fast, cost-effective and easily installed system would be needed.

Whilst several system options were available to the contractor, speed was of the essence. This led KTTL to investigate UV cure options more closely. Ultimately, the Berolina-Liner System was chosen for the work.

Berolina-Liners are seamless, glass fibre reinforced web constructions, the basic material being dependent on the requirement profile, or are produced as a sandwich construction using both materials. They are easily cured using an Ultra Violet Light train to activate the resin impregnated into the liner materials, which are theoretically infinitely elastic. This special feature is made possible by the patented engineering wall construction.

The fibre fabrics in the Berolina-Liner overlap and are arranged so that the overlaps are staggered, a technique which according to BKP offers definite advantages including:

The Berolina-Liner can be installed in one piece, even at cross-sectional and/or profile crossovers and easily adjusts to match the local conditions.

The continuous fibre orientation in the direction of the circumference optimises the external loads without hindering elasticity.

Berolina-Liners are delivered to the site ready for installation, having been factory impregnated with the UV cure resin. In this way they can if necessary be stored for up to 6 month.

For a liner installation, a protective semi-section film sleeve is first drawn into the pipe to be rehabilitated using a winch and then the ready-made Berolina-Liner is drawn through the sewer, sliding along the semi-section. Both ends are closed with packers and the tube is inflated with compressed air with a minimum pressure of 0.5 bar which forces the liner fully against the inside wall of the host pipe.

The impregnated liner materials are situated between two airtight and waterproof flexible tubes. The outer tube of the Berolina-Liner prevents contamination of the soil and groundwater and also prevents the resin from penetrating into any laterals that may be present along the length of pipe being treated. The outer tube is also UV-tight so preventing any curing of the liner during transport or handling.

A UV light source is then passed through the compressed air filled liner, if necessary with CCTV control. The UV light source activates the curing process of the resin curing the liner into position. The second, inner protective tube is then removed. If the tube ends are sealed, the hardening/curing process occurs free of emissions. In this way, an environmentally friendly, stable inner lining is

produced for all common pipe materials, including brick sewers, in a short time. The negligible reduction in the original

cross-section is virtually balanced out by the smooth, abrasion-proof inner surface of the Berolina-Liner. Laterals can easily be found following

the curing process as they are clearly visible in the Berolina-Liner due to its high stretching properties. They are opened using a conventional cutting process.

As well as proven application in the field, the Berolina-Liner has also undergone significant testing by internationally recognised materials and testing organisations such as WRc. Under the testing regime of the WRc, Berolina-Liner manhole to manhole lining system has achieved ‘WRc Approved’ status whereby the liner production method, installation technique and product support has been scrutinised by WRc and found to meet its exacting standards. The Berolina-Liner system has also undergone and passed stringent testing in respect of its leak-tightness subsequent to installation and its ability to prevent infiltration.

KOMATSU INSTALLTIONS On the Komatsu site the timing for the works was just seven days. Work started on a Saturday and finished the following Saturday with some 18 individual lining set ups having to be achieved in that time whilst working around other site contractors.

On one set up, one problem occurred when, due to pipe deformation, a 30 m section of host pipe was virtually closed up to the point where it was only just possible to pass a jetting hose through it. Given the client’s insistence that an open cut option to expose this defect could not be used given the time frame involved, the KTTL crew attempted the installation even though the outcome was uncertain. Eventually the crew managed to get through the deformed section, only to discover a huge hole in the host pipe. Despite this a line was passed through the defect and a sacrificial pre-liner was pulled into place over the hole prior to lining with the intended reinforced liner. Lining was the Berolina-Liner was ultimately achieved successfully, as were the remainder of the other 18 lining operations.

For KTTL, Dave Bushby, Managing Director said: “The circumstances of the Komatsu site were not at all easy. Limited access, tight time scales and the requirement to do the whole job without interrupting plant production, could have made the job a very difficult one. However the minimal equipment requirement, the speed and ease of installation offered by the Berolina-Liner system and the support offered by the manufacturer’s representative meant that the job went very smoothly, even when the host pipe was virtually non-existent and access was difficult. The UV Cure option really can make the difference on jobs like this.”

Representing BKP Berolina-Liner, Borje Persson said of the Komatsu project: “This is the sort of project that the Berolina-Liner was designed for. The simplicity, yet strength, of the liner and the installation technique is such that, with good logistical control, the one liner truck that is required on site can be located some distance from the pipe access point, overcoming many access difficulties. The speed of the installation is also a key factor. How many other liner options can achieve 18 individual liner installations in just 7 days – that is over 2 liners per day.”

Commenting on the project for Komatsu UK, Paul Collins, Building Maintenance Manager stated: “We selected Environmental Services North East Ltd to carry out this repair due to the location of the drain and the amazing ground breaking technology offered. The professional approach by KTTL was second to none and a full survey and repair method was fully communicated. What could have

been very disruptive to our production turned out to be a quick and simple repair with zero effect to our busy production schedule. Since the repair we have used the liner method many times to maintain and repair out waste frame work. The advantages of using such a repair method are numerous, the fact there is very little disruption to the repair vicinity and no environmental impacts compared to other repair methods are just a few.” Website: www.bkp-berolina.de

REHABILITATION WASTERWATER ASSETS ACROSS THE UK

O ne of the UK’s leading sewer and pipeline rehabilitation specialists Ferro Monk Systems, part of the Clugston Group of companies, recently completed a number of major projects with its revolutionary spray applied, environmentally friendly, 100% epoxy resin coat-ing system known as Ultracoat.

The projects, which were at different locations across the UK including; Spalding and Canvey Island, were for clients that recognise the importance of maintaining Wastewater assets.

All the projects were very different in nature and required the Ferro Monk team to work closely with both the main contractor company and its client, to understand each project’s specific requirements.

In keeping with current national environmental standards, Ultracoat is a ‘green’ product - 100% epoxy with no volatile organic compounds. It has a high safety value and can be applied in confined spaces with no risk of combustion to hazardous materials. It is also resistant to algae and bacterial growth.

One of the major benefits of Ultracoat is that it can be sprayed onto damp surfaces and applied quickly. Its high bond strength means it can strengthen corroded or weakened structures and it can adhere to most surfaces, including concrete, steel, brick, fibreglass and clay. Most interestingly it can be used on a variety of tanks, chambers, manholes and culverts.

Wet chambers and surfaces are notoriously difficult to deal with, but Ultracoat is designed for use in damp environments. It bonds well and systems can be back in use within as little as two hours after application. This was an essential factor in the success of all the recent projects.

Terry Warrie, project manager for Barhale Construction said, “It made our lives easier on a difficult project to use the expertise of Ferro Monk, a company that clearly understood our requirements and which performed well within all aspects; safety, quality and standard of workmanship.” He added: “All Ferro Monk’s employees were professional to deal with and the projects, which had the potential to cause concern to us, went extremely well thanks to the approach and attitude of Ferro Monk.”

Danny Heffernan, managing director of Ferro Monk Systems said: “Ultracoat is proving to be an ideal application in today’s environmentally friendly conscious world.”

Ferro Monk specialises in the repair and rehabilitation services for sewers, culverts, pipelines and associated tanks, vessels or chambers from initial inspection through to design, and finally the construction phase. Website: www.ferromonk.co.uk

HDD FOR BEGINNERS

I n a world where space is becoming a premium having the facility to do utility work within a small footprint is becoming increasingly popular. The small, compact and therefore very flexible HDD bore rig GRUNDODRILL 4 X from Tracto-Technik is designed to be suitable in tight working conditions and has been proven in sandy-clay type soils. The small set up area and the low weight hardly cause any surface damage. The GRUNDODRILL 4 X is especially suited in areas that are difficult to access, where transportation of a heavy machine would be a problem, in residential areas, on tight paths, for house connections for sewage, fibre optic cables, gas, water or for connections to wind power stations.

With an operating distance of more than 100 m bores can be expanded to a maximum 235 mm diameter. The performance potential of the bore rig is supported by the option of two mixing systems. The rig is especially recommended for HDD beginners.

SITE APPLICATION

In the town of Schmallenberg, Germany there several sculptured concrete figures of everyday people all over the town, which the artist Christel Lechner has created. Figures include sculptures such as a couple reading on a bench in the middle of a traffic roundabout.

Enthusiasts of these figures had the idea to light up this couple in the evenings. A power cable had to be installed from the closest street lamp over a length of 50 m. This proved to be an ideal task for a GRUNDODRILL 4 X, which carried out the task successfully in just half a working day. Website: www.tracto-technik.com

EXETER LINK MAIN SCHEME HDD CROSSING

S outh West Water, one of the UKs main water companies, recently undertook a £2.4 million scheme to improve water quality around Exeter, Devon including the installation of a 300 mm (12 in ) diameter pipeline which was to run inside a 400 mm (16 in) diameter sleeve. The installation runs under the River Exe, the Exeter Canal, the Penzance to Paddington main line railway and an overpass of the M5 motorway.

The downstream system from Topsham Tower forms part of South West Water’s Section 19 undertaking to improve water quality in defined areas by December 2009

Using one of the biggest drills in the country for this type of work, South West Water is completing the installation of a new water main from a supply reservoir.

The scheme is the largest-single investment in the company’s £400 million water mains rehabilitation scheme, which has so far renovated and relined over 3,000 km of pipeline.

This significant capital programme of improvement works began back in 2000 and has already put the sparkle back into the water for ten of thousands of homes across the South West Water region.

It is understood that engineering projects like this can cause some inconvenience but the work was essential and a real investment in the city’s infrastructure.

Graham Murphy, Director of Engineering, South West Water, said: “This was one of the final milestones in our 10-year programme, which draws to a close later this year. For this scheme we decided to install a new pipeline, as the existing water main is located along Topsham Road, so

renovating it would have caused major disruption to the arterial route into Exeter from the south. As well as crossing the River Exe, Exeter Canal, M5 overpass and Paddington to Penzance railway line at Milbury Lane, the work was also around Sites of Special Scientific Interest (SSSI), RSPB protected land and the Exminster Marshes. The scheme was completed by 30 September 2009 so that there was no interference with the winter wetlands habitat.”

The network which links Pynes Water Treatment Works (WTW) to Topsham Tower comprised approximately 19.3 km of 10 in and 18 in diameter cast iron trunk mains which was identified during the project assessment as the principle source for a local deterioration in water quality.

The major part of the supply system is located along Topsham Road, the major arterial route into Exeter from the south. The significant cost and disruption of traffic flows and commercial activity in and around the city centre, coupled with interruptions to customer supplies and the practical difficulty of rehabilitating these mains, highlighted the need for an alternative solution.

OPTIONS There were two options considered for the project. Option 1 comprised utilising the non structural method of in-situ polymeric spray lining to renovate the existing trunk mains. The estimated cost of completing the 19.3 km was approximately £4.21 million. With the existing mains located predominantly in an urban environment with operating restrictions completion of this option by December 2009 would have been difficult. Disruption to connected customers would also be significant during the construction phase.

Option 2 comprised installation of a new 300 mm diameter link main installed from the end of the Pearce’s Hill to a connection on Topsham Road, Topsham side of Countess Wear roundabout. The required length of the link main was estimated at 2.7 km at a cost of £2.4 million.

This link would involve crossing the River Exe, the Exeter Canal, the Paddington to Penzance main line railway and the A379 road to Exminster and Dawlish.

As a result, directional drilling of the River Exe, the Exeter Canal and auger boring under the railway line were identified as the most appropriate techniques for the link.

Given the accessibility issues associated with this mains route and future maintenance/security of supply requirements, the installation of a dual link under the river and canal was proposed.

Future accessibility issues associated with Option 2 were minimised by proposing to ultimately convert the drilling mud line to a potable water main by inserting a smaller diameter pipe within this installation under the River Exe and the Exeter Canal so dramatically reducing the risk to the network with minimal impact on connected customers.

With any project utilising directional drilling and auger boring a major risk is a change in ground conditions previously not identified but this risk was minimised for all by extensive site investigations during the design phase.

Dave Raw, Balfour Beatty Utility Solutions Operations Manager, said: “We worked with South West Water to build customer service and environmental issues into our plans for this project from the very beginning. The directional drilling technique is perfect for a scheme like this, despite the

challenges the different terrains of the River Exe and the M5 motorway bring. Using the technique meant we could carry out construction quickly and efficiently without affecting customers or the environment, avoiding the months of disruption alternative techniques would have caused.”

Peter Hodgson, Allen Watson Ltd, said: “Drilling fluid (mud) is a key component of the directional drilling operation fulfilling

many vital functions. It is used to drive the cutting head during piloting, support the bore, suspend and carry cuttings out of the hole, cool and clean the cutters, lubricate the drill pipe, balance the ground water preventing ingress and seal any permeable geology preventing loss of mud into the ground. The mud consists of water mixed with approximately 3% bentonite, a naturally occurring clay chosen because it has thixotropic properties meaning it can be pumped as a liquid but will gel when stationary preventing the rock cuttings from settling to the bottom of the hole. Several million litres of mud need to be pumped during the drilling process in Exeter. Mud is pumped down a hole through the drill rods and returns to surface through the open bore carrying rock fragments from the cutters. The returning mud is recycled through a sequence of vibrating screens and hydrocyclones which remove rock cuttings, sand and silt. The suspended solids content of the mud is reduced from as much as 25% to less than 0.1% when it is pumped down the hole again. By recycling the total mud in circulation can be kept to a minimum and over the course of the project is recycled many hundreds of times.” Websites: www.allenwatson.com or www.southwestwater.co.uk

SCANPROBE/RENOLINE MOVE FORWARD INTO THE 21ST CENTURY

H aving been based at is previous site in Warlingham, Surrey, UK since their formation in the 1980s sister companies Scanprobe and Renoline are bucking the trend in the current drainage industry climate and have moved into modern and larger facilities. Whilst still remaining in the same area, the two companies have seen such rapid growth recently that they have now outgrown the old premises and the move into the new state-of-the-art building ensures future expansion for their business operations.

Providing a one-stop shop for CCTV drainage inspection cameras, lining materials and equipment, the new building, in Kenley, Surrey, is over three times the size of the previous unit in Warlingham and incorporates smart new offices, warehouse and factory facilities, together with the creation of a new trade counter. Ample parking for 30 vehicles is now also available at the 8,000 ft2 property to encourage valued customers to come and visit the offices where stocks of all camera equipment, liners, resins and drainage tools are available for hire or purchase.

Seizing the opportunity to move to bigger premises at such a time, Scanprobe and Renoline are showing that they have the confidence to move forward and plan for future years of trading. After recently branching out and opening a new office in Norwich and totally redesigning both its websites, the companies are demonstrating their commitment to future investment to benefit customers, whilst at the same time leading the industry in innovation.

Jon Barry, Managing Director said: “The last decade has seen substantial growth in turnover for us and now is definitely the right time to move to a larger and better equipped site. We are preparing for an exciting period of future expansion which underlines the commitment that we can provide even more flexibility and availability of products to our valued customers.”

Furthermore, Following an assessment by an independent body, Scanprobe Technique Ltd has been awarded ISO 9001 certification. This certification has only been achieved by about 5% of UK businesses and this prestigious award is supported by the Government and recognised worldwide.

Said a delighted Jon Barry, “We have always been proud of the service we offer our clients and the way that we conduct our business. Now with the award of ISO 9001 certification, this has been confirmed by outside experts who are used to judging standards on a daily basis in a wide variety of trades and industries”.

Mr Steve Dean, who undertook the assessment for QMS Quality Management Systems, paid particular tribute to “the investment in people and training that enables Scanprobe Technique Ltd to provide an efficient service to its customers”.

Over the next few months, Scanprobe will complete development of a new range of camera systems as well as launching a new range of Epoxy and Silicate drain resins, all of which will be available to purchase through its 24/7 online shopping facility via the companies websites.

NEW SYSTEM Recently, the first of these launches was the new Colourprobe 2000 Tractor pipeline inspection system. The Colourprobe 2000 Pan & Tilt inspection system is designed for surveying pipes from 150 mm to 600 mm diameter and records surveys directly onto SD cards, CS cards and DVD. The unit can be powered from either 110 or 240 volt power outlets. It comes supplied with a

standard 150 m cable, and offers text and on-screen meterage. The Control Unit is supplied in a rugged carry case that is lightweight and easily portable. All the controls for operating the system are incorporated into the control unit with a compact keyboard, along with a text generating system.

The Pan & Tilt Inspection Camera is permanently fixed to the front of the crawler. The whole camera and crawler system design has been kept as short as possible to allow easy access to the pipe via manholes. A range of wheels and spacers provides for inspections in pipes from 150 mm diameter to 600 mm diameter.

The Crawler is fitted with a powerful 150 W 48 V DC Motor, which is fitted to a 42 mm diameter planetary gearbox. This gives a maximum output torque of 15 Nm. Drive to the axle is via a 1:2 bevel gear set and conversion to 4 wheel-drive via a chain and sprockets.

The Cable Drum has a maximum capacity of 150 m, and is a manual hand wind, and layering system. It incorporates a slip ring assembly which allows for continuous operation, with no interference on the monitor. Using a 0.25 m cable counter wheel and encoder, it measures the amount of cable being used to give an accurate position of the camera/crawler in the pipe. This information is displayed in the text generator on the monitor. Website: www.scanprobe.com

D espite appalling weather the biannual programme of road show events got off to an excellent start at the Holiday Inn at Bristol on the 10 November. UKSTT chairman, Colin Tickle, introduced and controlled the varied and diverse programme of technical papers delivered by knowledgeable, experienced practitioners and specialists was well received and proved popular throughout the day.

Covering a broad range of water and wastewater topics much of the practical experience and knowledge being shared translated across all sectors of trenchless working.

The seminar programme was very well supported by a broad range of exhibitors which ensured that there was something for everyone to see and discuss during breaks for refreshment and networking.

If this opening event was a taster then with the pre-committed support of Yorkshire Water as sponsors, as well as advance delegate bookings already accelerating, we are in for a terrific time at Wakefield at the next event on 1 December.

NEW CITY & GUILDS QUALIFICATIONS LAUNCHED FOR CIPP OPERATIONS

D evelop Training Limited is proud to announce the launch of three new Cured In Place Pipe lining qualifications accredited by City & Guilds, installation units involving heat and ambient cure techniques and also localised repairs have been developed following consultation with the UKSTT and its members resulting in stand alone units of accreditation for successful candidates.

Develop and UKSTT in their continuous drive to promote the competence, safe operation and effective management of trenchless technology operations have combined their respective expertise to develop training and assessment for operatives, technical personnel and managers operating in the trenchless sector.

Develop in partnership with UKSTT can offer City & Guilds qualifications via the ‘Certification of Utility Operations’ 5831 scheme, the scheme consists of discrete units of competence which recognise practical skills, safety awareness and knowledge & understanding. Assessments of competence can be carried out by direct observation in the work place or via essential knowledge questioning in a classroom environment.

Operatives who are successful in both the practical assessments and the essential knowledge examination will receive a City & Guilds certificate in the subject area they have undertaken, candidates undertaking the various management supervisory units are required to undertake an essential knowledge assessment and again if successful will receive a City & Guilds qualification. These qualifications could be used as evidence towards a full NVQ as the candidate develops their careers.

Apart from these new modules City & Guilds qualifications can be obtained in many other related trenchless disciplines all of which are detailed on the UKSTT web site and in addition Develop can offer a number of other utility qualifications via City & Guilds, which include:

• CCTV pipe line inspection. • Butt and Electro fusion of PE pipe lines (Gas and Water). • Installation, testing and commissioning of PE systems. • Safe use of coil trailers. • Location and avoidance of under ground apparatus. • Signing, Lighting and Guarding. • Safe excavation in the highway. • Use of trench support systems.

Finally, following further consultation with UKSTT and its members Develop is currently designing a unit of competence in ‘Winching Operations’ this will be available from early next year becoming part of the suite of 5831 units available to the trenchless technology sector.
