Back on October 15 and 16, 2001 ourChapter held a two-day seminar dealingwith the Best Practices for HorizontalDirectional Drilling (HDD) in Toronto,Ontario. This was the second course andfirst time in Canada based on therecently released HDD Best PracticesGuidelines book. The seminar was asuccess, with fifty (50) attendees. Themajority of the participants were fromacross Ontario, Alberta and Quebec,with instructors from Arizona,California, Texas and Alberta. Theattendees’ backgrounds were quitevaried from consultants to contractors toowners.

The purpose of the Seminar was tointroduce the HDD Best Practices thatare being used across North America.The course provided the participantswith a document and course that hasbeen supported and prepared by expertsin the field. The guidelines weredeveloped by members of theDirectional Crossing ContractorsAssociation, Distribution ContractorsAssociation, Equipment ManufacturersInstitute, National Utility ContractorsAssociation, North American Society forTrenchless Technology, and Power &

Communications ContractorsAssociation. The HDD Best PracticesGuideline book is available throughNASTT (www.nastt.org) publications.

The seminar’s main objective was toprovide the contractors, engineers andowners with a set of guidelines that willassist and demonstrate to their personnela way to strive for successful HDDinstallations, by training operators andsupervisory personnel. This BestPractices seminar is a prelude to themore detailed HDD course, which ismore practical in approach. The Chapteris looking into hosting this more

advanced course in this calendar year(2002).

We were fortunate to have the foremostexperts in the HDD field, such as Dr.Sam Ariaratnam of Arizona StateUniversity, David Bennett of BennettStaheli Engineers, Frank Canon ofBaroid Drilling Fluids and Casey Comoformerly of Digital Control Inc. to haveconducted the course.

A great thanks to Ernie Ting, FrankBadinski and Patrick Cheung for theirefforts in co-ordinating the conferencedetails.

Happy New Year to our members,colleagues and to all. 2001 has been abusy year for the construction industryincluding the trenchless technologysector. In spite of Sept. 11, and with thehelp of other factors there has been nosign of slow down in construction.

The NASTT Great Lakes and SaintLawrence Chapter (GLSL) has activelyparticipated in several conferences andprovided two educational workshops lastyear. The “No-Dig 2001” held at theOpryland Hotel in Nashville, Tennesseewas attended by a large contingent ofCanadians. Several Canadian trenchlesstechnologies research and projects werepresented during the conference. Theevent was the tenth anniversary of theNorth American Society of theTrenchless Technology (NASTT). At thegala dinner, NASTT presented awards tovarious stakeholders for their significantcontribution to the trenchless technologyindustry. We were very proud that fivecities and municipalities, a consultant,two research universities and a researchcentre in Canada were among therecipients of the awards presented. Thisshows that we Canadians are well up todate and much involved in trenchlesstechnology research and construction.

In May 2001, GLSL conducted a one-day workshop entitled “Out ofSight…Not Out of Mind” focusing onunderground diagnostics andinstallations when dealing withtrenchless technology. Last October, atwo days course on “HorizontalDirectional Drilling Best Practices” washeld in downtown Toronto. This was thesecond seminar after the one held inNashville last April. The coursefollowed the new HDD Good PracticesGuidelines book developed by the HDDconsortium. Authors of the book andleaders in the industry were on hand toprovide their expertise. Attendees gave ahigh evaluation and satisfaction on theinstructors and course content.

This will be a busy year for us. Severalof us are involve in developing theNational Guide to SustainableInfrastructure spearheaded by theNational Research Council (NRC) andFederation of Canadian Municipalities(FCM). We will be participating at theNo-Dig 2002 to be held Montreal April28 to May 1, 2002. An early Marchworkshop in Ottawa, a cctv NAAPIcourse this Spring, and a workshop inthe Maritimes mid-year are beingplanned.

I welcome and congratulate thefollowing new board members: EricBoere (Region of Halton); KamranSarrami (City of Toronto); Derek Potvin(Robinson Consulting, Inc.); and BenoitGrodin (CIMA, Quebec). As past boardmember for several years and the newlyelected chair of the GLSL, my tasksalong with the board members arechallenging. We have to juggle andextend our busy schedules and regularwork to meet the tasks ahead of us. Ourpast endeavours have been successfuldue to our able board members and pastchairs namely Piero Salvo, JoeLoiacono, Grant Murphy and RalphDavidson.

Our organization’s mission is to advancethe science and practice of trenchlesstechnology for the public benefit, topromote and conduct education, trainingand facilitate study and research andprovide information to all interested andconcerned parties. To date, very fewCanadian cities, municipalities andutility companies are employing or haveemployed one form of trenchlesstechnology or another. There are still alarge number of owners that are notachieving the financial and social costbenefits of trenchless technology forreplacement and rehabilitation of theirinfrastructure. Lack of knowledge abouttrenchless technology methods, itscapabilities and limitations and the rightapplication as well as lack ofspecifications were among the barriers

that are preventing the owners to use anyof the replacement and repair methodsavailable.

I strongly encourage individuals at thevarious levels of government, utility andprivate owners of undergroundinfrastructures to learn more abouttrenchless technology by attendingworkshops, seminars, conferences, etc.provided by us and other interestsgroups.

If you want to learn more abouttrenchless technology, join ourorganization. Get involved and I canassure you that you will achievepersonal, professional and projectbenefits. If you are interested in joiningus or contemplating on a project or justhave a question, contact me or any ofour board members by e-mail or bycalling us. If you want to be placed onour mailing or e-mail lists, please let usknow. You can also visit our web site atwww.nasttglsl.on.ca or www.nastt.org.

Structural Watermain Rehabilitation – An Ontario First by Mike Willmets

In October 2001, the City of Ottawa became the first Ontario City to have a structural liner installed in their watermaindistribution system. The project consisted of rehabilitating 3 kilometres of 1960 vintage unlined 152 mm cast ironwatermain. Half the project was epoxy resin lined and the second half was rehabilitated using a polyester woven fabric, withan internal polyurethane lining. This structural liner was then impregnated with a two-part epoxy resin that has both NSFand BNQ approvals. This new Sanexen product, known as Aqua-Pipe, is classified as a cured in place pipe (CIPP).

Parts of the Crystal Beach area of Ottawa have been subject to numerous watermain breaks as well as dirty or “red” watercomplaints for the years. An investigation of maintenance records and other infrastructure needs revealed that a structuraloption was appropriate for approximately half the target area. The remainder of the Crystal Beach watermains wereconsidered to be generally structurally sound but subject to red water and low flow problems due to internal corrosion.

While new to Ontario, approximately 20 kilometres of this new structural liner has been installed in the Province of Quebecover the last 3 years. Of particular note, is that once the liner has cured, the water service connections are reinstated from theinside of the pipe by utilizing a robotic cutter and CCTV. The use of robotics dramatically reduces the number ofexcavations required for this “low-dig” technology.

Initial results of the project are extremely favourable and the City is currently evaluating additional sites for theserehabilitation techniques. The engineering firm of WSA Trenchless Consultants, Aqua-Rehab Ltd., Sanexen TechnologiesInc. and the City were pleased to host visiting groups from numerous municipalities who travelled to Ottawa to witness thesetechnologies first hand.

Réhabilitation structurelle des conduites d’aqueduc – une première ontarienne

La ville d’Ottawa est devenue au mois d’octobre dernier, la première ville ontarienne à se doter d’un revêtement structurel àl’intérieur de son réseau de distribution d’eau. Le projet consistait à réhabiliter trois kilomètres de conduites d’aqueduc enfonte de 152 mm datant de 1960. La première portion du projet a été nettoyée puis revêtue d’un enduit à l’époxy (non-structurel) tandis que la seconde moitié fut chemisée à l’aide d’un tissu de fibres de polyester et d’un revêtement interne enpolyuréthane. Au moment de l’insertion, le revêtement structurel a été imprégné de deux composés d’époxy approuvés parle BNQ et le NSF pour les conduites d’eau potable. Le produit, Aqua Pipe, est classé comme technique de chemisage.

Situé dans le secteur Crystal Beach d’Ottawa, ces conduites d’aqueduc âgées de 40 ans étaient sujettes à de nombreux bris etfaisaient l’objet de nombreuses plaintes d’eau rouillée. L’inventaire des bris a permis à la Ville d’opter pour deux techniquesde réhabilitation sans tranchée, l’une structurelle, l’autre non.

Environ vingt-et-un kilomètres du revêtement Aqua Pipe F4960 a été installé au Québec au cours des trois dernières années.Une fois le revêtement mûri, les branchements de service sont rétablis à l’intérieur de la conduite à l’aide d’un robot.

Michael Willmets, Directeur de projets à la Ville d’Ottawa se dit extrêmement satisfait des premiers résultats et de larapidité du projet. Consultants sans tranchée WSA assure l’ingénierie et la supervision de chantier de ce projet innovateur.

Technology Transfer :INFRA 2001 Delivers!

When we at the Centre for Expertise andResearch on Infrastructures in UrbanAreas (CERIU) decided to pursue thegoal of organizing a conference dealingwith technology transfer, we werehoping to be able to cover the multiplefacets of this theme, as determined bythose working directly in the field ofinfrastructure rehabilitation. Thistechnology transfer-based focus was afirst in the rehabilitation sector andoccurred at a very fitting time,considering the municipal restructuringthat came into effect in January 2002.One of the first conclusions drawn in thepreliminary report drafted by the INFRA2001 Organizing Committee is that theevent enjoyed a favourable turnout ofinfrastructure professionals (engineers,managers, elected officials and otherspecialists), who once again were giventhe chance to discuss new technologies,technology transfer in its various formsand, above all, the importance of soundurban infrastructure management.

The success of this seventh edition ofUrban Infrastructures Week was in largepart due to the support and resourcesprovided to CERIU by variousinstitutional players throughout the pastyear, namely the Quebec Ministry forMunicipal Affairs and Greater Montreal,Canada Economic Development, theQuebec Ministry of Research, Scienceand Technology and the École detechnologie supérieure. It is alsoessential that we voice our appreciationfor the ongoing support we havereceived from our major partners –Transport Canada, the Quebec Ministryof Industry and Commerce, the QuebecMinistry of Transport, Hydro-Québec,Vidéotron and the City of Laval

INFRA 2001 was held from November26 to 28, 2001 at the Holiday InnMontreal-Midtown and welcomed a totalof 730 participants from 180

organizations throughout Quebec, therest of Canada and abroad. We werealso very pleased with the interest shownin Urban Infrastructures Week bystudents, who represented 10% of thisyear’s attendees.

The conference program was verydiversified, offering participants theopportunity to take part in 18 differenttypes of activities over the three-dayperiod, including technology workshops,technical conferences, the openingreception, an activity entitled InnovationShowcase, the Evening of Excellenceand a luncheon talk. Attendees took fulladvantage of these events to meet andconverse with the over 80 keynotespeakers specializing in sectors such asunderground infrastructures, newmanagement solutions, and pavements,bridges, tunnels and retaining walls.

In addition, given that we opted not tohold a formal exhibit this year, theOrganizing Committee invitedcontractors, suppliers and organizationsto integrate the INFRA 2001 theme intothree special activities: poster sessions,wherein companies were invited todisplay their corporate brochures in thevarious conference rooms; a sessionentitled Innovation Showcase, held inthe hall adjacent to the conference

rooms; and technical workshops, wherea room was set aside for the presentationof products and services. This newapproach was pronounced a success bythe 14 organizations involved as well asthe conference participants.

The INFRA 2001 opening ceremoniesenabled Robert L. Papineau, DirectorGeneral of the École de technologiesupérieure and Chairman of the INFRA2001 Organizing Committee, ClaudeBoucher, Secretary of State forMunicipal Infrastructures for the QuebecMinistry for Municipal Affairs, andGilbert Drouin, the head of Valorisation-Recherche Québec, to lay thegroundwork for the remainder of theconference. Mr. Papineau set the tonefor INFRA 2001 by reminding his fellowcolleagues that efficient networking wasessential and that the rehabilitationindustry needed more than the annualINFRA conference to ensure the qualityand durability of urban infrastructures.

During Monday’s luncheon talk, INFRA2001 Honorary President David Cliche,Quebec Minister responsible forResearch, Science and Technology,addressed an audience of 160 people.He started off by saying that Quebec hassuccessfully made its mark in the field inrecent years and has carved out a choice

Among the Attendees: Wayne Green (City of Toronto), Serge Pourreaux (GeneralManager CERIU), Brad Johns (City of Dryden)

position for itself throughout Canada andthe world in terms of new technologiesand the technological innovationsdeveloped in its research centres. Hewent on to congratulate CERIU’sinitiative in putting together INFRA2001 to emphasize the importance ofresearch into new infrastructurerehabilitation methods – despite the lackof official recognition as a networkingand technology transfer agency. He alsopromised to remedy this situation assoon as his ministry’s budget allowed it.

At the Evening of Excellence, held at theRestaurant Hélène de Champlain, 150guests were on hand for the sixth editionof the Award for TechnologicalInnovation, given by the Ministry forMunicipal Affairs and Greater Montreal.This year’s recipient was the City ofWaterloo (Qc), which was singled outfor its Biological Filtration Plant forIron and Manganese Removal.

During the course of this ceremony,CERIU also handed out for the secondyear in a row its awards for distinctionand excellence to honour individuals andorganizations working in the urbaninfrastructure field who, through theirinvolvement during the previous year,made an outstanding contribution toCERIU’s development. The winners for2001 are the Union des municipalités duQuébec (institutional), the Cities ofDorval and Verdun (municipal) andGéophysique GPR International(corporate). Lastly, the CERIUAmbassador award was given to ClaudeVincent, formerly with the City ofQuebec, for having played a major rolein making CERIU what it is today.

Overall, in the opinion of the vastmajority of those involved, INFRA 2001was, once again this year, a success interms of the quality of the program, thenumber of participants and the highcalibre of the information exchangedduring the conference.

National Guide to SustainableMunicipal Infrastructure

With funding from the InfrastructureCanada Program, the Federation ofCanadian Municipalities and theNational Research Council a NationalGuide to Sustainable MunicipalInfrastructure is being prepared toprovide municipalities with the bestavailable solutions in dealing with theirMunicipal Infrastructures. This guidewill address the following with respectto the Municipal Infrastructure:planning, design, construction,management, assessment, maintenanceand rehabilitation.

The National Guide has sought theparticipation of different professions,from politicians all the way to thesystem operators. The Guide’s mainobjective is to provide a “decision-making and investment planning tool, aswell as a compendium of technical bestpractices.”

Given the vastness of the project, thefollowing areas are being considered atthis stage; Decision-Making &Investment Planning, EnvironmentalProtocols, Municipal Roads andSidewalks, Potable Water, and Stormand Wastewater. The differentTechnical Committees and Workinggroups are addressing a total of sixteen(16) specific areas. The National Guidehas retained the services of severalorganizations to collect pertinentinformation relating to each specificarea, which will assist the committees inpreparing the Best Practices for theNational Guide.

As it stands at this moment, the GreatLakes St-Lawrence Chapter has six (6)board members that are activelyinvolved with the National Guide. TimDennis, Ernie Ting and Piero Salvo siton the Potable Water TechnicalCommittee. Tim Dennis also acts asVice-Chairman of this Committee.Other members, Kamran Sarrami andMichael Willmets, are participating inone of the Working groups that deal withestablishing best practices to determinethe use of trenchless rehabilitationtechniques. Mike Willmets has beenselected as Chairman of that workinggroup, in which Piero Salvo is alsoparticipating.

Ernie Ting is participating in Inspectionand Assessment working group, as well.The sixth board member participating isJoe Loiacono. Mr. Loiacono isparticipating as part of his work with theCERIU that is carrying out certainmandates for the Guide.

The goal of the Potable WaterCommittee is to identify the following:

• How to reduce losses in transmissionand distribution systems - wateraccountability

• How to determine what causes thetransmission/distribution system todeteriorate and fail

• Inspection, condition assessment,and evaluation of performance ofwater transmission and distributionsystems, both in terms of structureimpact on the way things are doneacross Canada.

Ottawa Sewer RehabilitationSuccess Story

by Gerald Bauer, P.Eng., R.V. AndersonAssociates Limited

Tackle 430 metres of deterioratinggravity sewer, 6 to 9 metres deep, 762mm and 914 mm in diameter and whatdo you have? A rehabilitation successstory—the various sections relined inseven days beneath collector roads, bikepaths, mall parking lots, and majorintersections.

The City of Ottawa identified the need torehabilitate a number of deterioratingsewer sections on their PinecrestSanitary Sewer Collector. CCTVinvestigations revealed five sections withconsiderable horizontal cracking alongthe haunches of the pipe and most jointsexhibited signs of infiltration. The extentof deficiencies raised concern with thestructural integrity of the pipe andbackfill.

The City of Ottawa retained R. V.Anderson Associates Limited, inassociation with J. L. Richards &Associates Limited to develop a costeffective solution to rehabilitate thesewer. The evaluation assessed bothconventional excavation and No-Digtechnologies considering the pipelocation and deficiencies.

Three sewer sections, each 762mm indiameter totalling 225 meters long, werelocated in the main entrance to a majorshopping centre. Two other sections, one762mm diameter, 93m long and one914mm diameter, 100m long, werelocated along the only access to a largebusiness area as well as a major transitstorage facility. The sewer ranged indepth from 5m to almost 8m and at leasthalf of the length of the pipe was locatedin a rock trench. The sewer was locatedin an easement with a 300mm diameterwatermain on one side within 3m of thesewer and a 1350mm diameter stormsewer, also in poor condition, on the

other side, again within 3m of the sewer.

Investigations revealed the granularbackfill surrounding the pipe had a highwater content and very little compaction.Each access structure was only 750mmin diameter with badly corroded rungsand no safety landings. The proposedsolution included two (2) basicoperations: line each sewer section witha seamless cured-in-place liner; and,replace each access structure with a1800mm diameter structure to allow forproper access.

An extensive traffic control plan, bypasspumping plan and communications planwere developed after meeting withrepresentatives from key businesses,transit operations, and traffic operations.The final plan met the needs of areabusinesses by allowing continuousaccess to the shopping and office areas,and uninterrupted transit service. It alsoallowed the contractor sufficientflexibility to meet the requirements ofthe lining process. Construction timingand phasing were coordinated aroundbusiness activities in the area.

SewerMatic Drain Services was awardedthe project for a cost of $1 Million withthe rehabilitation completed in the fall of2000.

New Board Members: Derek Potvin, Eric Boere, Benoit Grodin with newlyelected chair Ernie Ting. (Kamran Sarrami missing.)
