INTRODUCTION This report provides a technical and functional assessment of all of the public aquatic facilities contained within the City of greater Bendigo Municipality District. The report has been requested by Mr Patrick Jess, Manager Recreation for the City. It is intended to examine and provide comment on the principal assets contained within each facility, particularly on a conditional and functional appraisal of those assets. It should be noted that the inspection on which the report is based has been carried out on a "walk-through" basis without intrusive examination of any part. Most pools have been in a non-operational mode, and pool tanks have generally contained water of limited visual clarity. The restrictions inherent on the findings and conclusions of the report are summarised in the limitations advice included in the Report. Given the number of aquatic facilities (13) inspected, and the diverse geographic locations, the report has been split into three parts. These parts being firstly the technical appraisal of facilities contained within the urban area of Bendigo ( 8), and secondly those that may be described as being in the rural parts of the city of greater Bendigo. The third section being the development and application of a set of criteria by which some objective view of the condition, and particularly functional effectiveness, may be obtained of each of the facilities. Accordingly, Section A describes the technical assessment of the urban area aquatic facilities, Section B those in the rural sector Finally Section C contains the developed criteria, and the individual assessment of all of the facilities within the city of greater Bendigo, along with an opinion of cost to bring the facilities (where practically feasible) to an approximate equivalency in performance.

Section A

TECHNICAL ASSESSMENT OF THE BENDIGO AQUATIC CENTRE 1.0 General Description of the Facility This facility is located in Barnard Street Bendigo and borders the QEO sportsground. It has recently undergone considerable refurbishment rebuilding, with a relatively new main building containing the various amenities, and providing direct access from Barnard Street. The land area for the facility is approximately 25,000 square metres. The centrally located aquatic facilities consist of five separate pools with the principal pool being 50 m and providing eight swimming lanes. A major attraction within the facility is a large tube slide accessed from a tower jointly used for access to the high diving boards to the adjacent diving pool. The main pool has plan dimensions of 50m x 18.3 m, and a depth range from 1.2 m to 2.1 m. The intermediate pool has plan dimensions of 18.3 m x 12.2 m, and a depth range from 0.62m to 0.9 m. The toddlers pool has an octagonal shape of side dimensions 12.2m, and a depth range of between 0.25m and 0.45m. The diving pool has plan dimensions of 18.3 m x 12.2 m, and a depth of 5.0 m. The splash pool for the slide has plan dimensions of 7.1 m x 4.8 m, and a depth of 1 m At the time of inspection, the main pool water treatment system was in operation, presumably as part of a maintenance regime to minimise the start-up procedures at the beginning of the season. Also the diving pool and the slide splash pool. Because of some difficulties with the sand filter on the small pools water treatment system, this part was not in operation. The extensive main building on the Barnard Street frontage is located in the southwestern corner of the facility. It consists of a ground floor below street level with the first floor providing direct access to Barnard Street. The plant room and associated treatment equipment are aligned on the southern boundary of the facility.

8

2.0 Pool and Ancillaries These pools have recently been subject to rehabilitation and configuration changes, excepting for the toddlers pool. The water treatment plant is also recently installed. 2.1 Pool Shells All of these pools have been constructed in cast in situ concrete, excepting for the slide splash pool which is understood to have been pneumatically placed concrete. It is understood the main pool has been converted to a wet deck style along the long sides. The other major modification has been the addition of a disabled persons access to the intermediate pool, and a part wet decking on one side of the pool. Subject to the restriction of inspecting the pools when full, no problems could be seen with the pool shells. 2.2 Paint Finish Evidence could be seen in the main pool, and particularly the diving pool, of deteriorating paint condition. These appear to require painting in the short term. The position with the minor pools appeared to be better, and the parts that could be viewed appeared in reasonably good condition. The splash pool is fully tiled. 2.3 Pool Furniture Extensive stainless steel guide railing and fencing associated with the disabled persons entry into the learner pool. Also four handrails on the entry steps at each shallow end corner. Four stainless steel climb out ladders in the main pool. All in good condition. 2.4 Tiling All pool tiling in good condition, with the pediment at the ends of both the main pool and intermediate pool fully tiled. A small chip apparently accidentally taken out of the main pool tiling at the southeastern corner. As noted, the splash pool is fully tiled and appeared to be in good condition. 2.5 Concourse Sections of the concourse are marginally below the recommended minimum widths.

9

For example the width around the toddlers pool is 1.9 m. On the east side of the main pool 1.8 m, and around the intermediate pool also 1.8 m. ( The desirable width being 3 m with a minimum of 2 m.). There are ample widths where pools are in proximity to one another and concourse taken from one pool to the other. Most of the concourse is in good condition. The exception is around the diving pool where there are areas of differential settlement between individual sections, and also some excessive gaps between those sections. Some of these would be toe hazards and should be treated. Some concrete grinding would assist, although it would be expected that some replacement sections would be needed. 2.6 Signage Depth markers have generally been indicated on the tile immediately behind the wet deck where this is applicable. These have been reinforced with markings on the concourse. The visibility of the tile markers is not high and the markings on the concourse could be reinforced. A depth indication has been shown on the shallow end pediment wall of the main pool. These markers also have low visibility. Depth marking of 5.0 m shown on the concourse for the diving pool, and the depth of 1 m shown on the wall of the splash pool. The usual recommendation for depth marking is for lettering to be at least 100 mm high and visible from the opposite side of the pool. This is always a difficulty with wet deck pools and one solution is to have small pillars behind the concourse with advisory notices about depths, and any other activity restrictions that might be appropriate. Eg. No diving. Other signage noted include: "Caution Shallow Water No Diving" at the intermediate pool ( 2 No) "No Running" – 4 No on the concourse in the vicinity of the toddlers pool, and again near the main pool, with two at each end. Similar treatment at the diving pool. A pictorial "No Diving" on the dividing fence between the toddlers pool and intermediate pool. Slide Rules of Use are attached to the slide access tower. Rules are similarly placed near the diving boards. A Code of Conduct sign is placed at the facility entry control point. 2.7 Poolside Shelter This appears to be limited within the facility. The toddlers pool has a shade cloth over it supported by a substantial galvanised steel frame. In good condition. Three umbrella style shelters have been placed on or near the pool concourses.

10

It is understood these are intended to have a role in life guard protection from the sun. There may be some competition to utilise these shelters. Consideration might be given to the provision of additional shelter at this facility. 2.8 Minor Poolside Assets Light Standards –7 No galvanised steel with paint finish. Good condition. Seating -- fairly limited provision. A steel/timber seat constructed around the balance tanks. 3 No older style Park benches near the toddlers pool. Paint within 12 months. Also 2 No steel/timber benches at the same location. 3 No steel/timber benches in the vicinity of the main pool. Timber requires painting. Aluminium bleacher style nears the diving pool. Barbecue -- provided. Slide at the intermediate pool -- appears be designed for children. Stands 1500 mm above ground. Hence not subject to the rules of operation for units over 2 m high. Has resilient ground protection under the structure. It is well fixed and braced and has an extension beyond the edge of the pool. Noted at one fixing point for the slide that some stress cracking in the fibreglass section has occurred. Despite being a relatively low structure, the prevention of users over balancing from the slide starting point remains an issue, as does the possibility of coming off the slide along its length. Suggest consideration be given to a set of rules for its use displayed near the unit. It is assumed that supervision of its use is appropriate. Water toys in the toddlers pool -- these consist of three frogs, a car and palm trees. Appear to be in good condition. Chain barrier -- consists of galvanised steel posts supporting chain sections on the outside edge of the concourse on the west side of the main pool and a short section on the east side. In good condition. Diving towers—1m and 3m towers are fabricated from tubular steel with paint finish. Corrosion can be seen around the base of the towers. This should be addressed in the near future. Land based toy-- a boat constructed of timber with paint finishes and placed on a resilient mat. Painted finishes showing wear and tear. Requires repainting in the near future. 2.9 Water Slide A major item of aquatic equipment. The slide tube sections from this level of inspection all appear in good condition, and the design apparently following contemporary design principles.

11

The problem area is a protective coating on the steel support and access structure. The protective coating appears to be an initial zinc galvanising, followed by an epoxy based paint coating. Known in the protective coating industry as a Duplex System. The advantage of the duplex system of this type is that a service life multiplier of two to four times the service life is achievable, as compared with using one or other of the coatings by themselves. Significant sections of the paint cover is being lost from the steps and from the horizontal beams within the structure. No losses observed on the columns. In many locations where the paint cover has been lost, there is some evidence of acceleration of the electrolytic reaction associated with degradation of the galvanising coating. As deterioration continues, rehabilitation will become more difficult and expensive and is likely to be less effective in the long run. The area of protective coating to steel is a complex one, and expert advice is required to diagnose and develop corrective procedures. It is most likely that some laboratory based investigation would need to be undertaken before the causes of the problem could be confidently established. As with most paint applied Systems, a non-expert view would be that this problem may be due to the final galvanising treatment that the various steel sections received before the paint application. Without discounting the effects of the time of painting, the environmental conditions at the time and the other issues that impinge upon the efficiency of paint coating application. Without knowing the history of the construction of the tower, the view expressed here is purely hypothetical. It may be significant that the columns are not showing the problem. It is surmised that perhaps the beams and the steps were separate supplies in the chain of supply prior to the construction. In this event, there may be some variation in the preparation of the components before assembly. A technique of chromate quenching is sometimes used after galvanising. It is understood that this can significantly affect the subsequent performance as a duplex system. Another factor that can be significant is the time elapsed from the galvanising to the paint application. Having regard to just these two points, it is suggested that there is a need for a careful investigation, and that action on this matter should not be delayed longer than is necessary. From an operational point of view, users of the slide enter a small splash pool . Water quality in this pool is maintained by conventional turnover, running off the main treatment system which also services the main pool and the diving pool. For the water flow required for the operation of the slide, an 11 kW Grundfos pump is located in a small steel clad shed near the discharge point of the slide.

12

3.0 Water Treatment 3.1 Pool Circulation Pattern For the main pool, with the wet deck conversion and central entry of the Filtered Water Return the circulation pattern would be regarded as good. Likewise for the intermediate pool, with a crossflow pattern from one side to the wet deck on the other. The diving pool has a floor entry, with a series of ports around the perimeter discharging Soiled Water back to the balance tank. In order to reach the ports, water flows over a section of ledge which effectively skims off the surface water. This pattern is regarded as good. The toddlers pool arrangement has some similarity to the diving pool in that the Soiled Water exits over a similar type of broad weir before entering a series of slots into the soiled water channel. There should similarly be a skimming affect in operation. The splash pool has a crossflow pattern with ports on one side which discharge back to the balance tank. The arrangement of the ports is such that it is likely that there is a degree of surface water removal. Combined with the likely rapid turnover, the circulation of this pool could be regarded as satisfactory. 3.2 Pipework (aboveground) Pipework is extensive, particularly as there are effectively two separate treatment and circulation systems in operation, with pipework as required. The pipework is almost exclusively PVC with a colour-coded paint finish. Elevated pipes are well supported on steel frames. Valves are clearly identified as to function and are all appropriate for the use. 3.3 Circulation Pump and Turnover Rates System 1 provides for the main pool, diving pool and splash pool. The pumps for this system are 2 No Southern Cross pumps in parallel, each driven by an 18.5 kW electric motor. These pumps are designated 150 x 125-250 with 264 mm impeller. The performance curve incorporated into the Operation and Maintenance Manual for these pumps has been examined. The duty point marked on the graph suggests a pumping rate for each pump of 94 l/s at a total hydraulic head of 12m. This Duty point is likely to be outside the desirable operating range of this pump.

13

A hand-written note has been added to the extract from the O & M manual as follows: ‘PWP 1 & 2 Main Recirculation Pumps 94 l/s @12.0m . 2 x 50% duty ‘ One of the key factors in the operating environment is the use of a butterfly valve on the discharge side of the dual pumps which has been permanently set in a throttling position. This effectively increases the hydraulic head over the pumps, causing a reduction in flow output. It seems possible that in the commissioning process a decision was made to reduce the pump outputs (into a better individual pump operating range), by manipulating the valve to achieve the performance noted. ie. For 2 pumps in parallel operation. A further more cryptic note on the extract indicates ‘ 140 reading’. A reasonable interpretation of all of this is that the dual pump output ( unthrottled ) was 140 l/s, and that the reduced flow is 94l/s . The pump technical data is reasonably consistent with this tentative conclusion. It should be emphasised that the tentative conclusion reached is obviously based upon a hypothetical interpretation of the sketchy available information. The only way to confirm or otherwise would be to measure flow and pressure at salient points in the hydraulic circuit . There are electronic means of measuring flow rates external to the pipe readily available. This not a difficult task. One thing is clear; the presence of relatively high flow throttling by a valve inevitably means energy loss. Considering operating costs, there may be a case to operate a single pump in certain circumstances eg. low patronage periods and overnight. Note that the O & M Manual includes a statement precluding alteration of the throttling valve without reference to Swimplex Aquatics, apparently the Manual author. This would seem to be the position accepted by the facility operators. While there is a flow meter provided on the discharge side of the pumps, it is apparently not operational, and an indication of actual flow cannot be obtained at the moment. It was also noted in the Technical Data section elsewhere in the O &M manual that the total flow rate of the system is 187 l/s.( This being 2x flow rate of each individual pump-an unlikely outcome). This information is grouped with pool turn over rates; presumably the turn over rates are based upon this quoted flow rate.

14

Note that unlike most pool pumps, these pumps have a flexible coupling between pump and motor. An annual inspection should be undertaken to ensure that the wear parts in these pumps are kept under surveillance and replaced where necessary. The pumps are set below ground level, thus minimising the suction head; in fact these pumps may be under positive suction head. They are equipped with stainless steel prefilters and also have a "no flow" device inserted into the discharge pipe in order to stop the system if flow is not occurring. Inspection shows a couple of developing external problems on the pumps. One pump has a leaking gland supply connection, and the other has some form of electrolytic corrosion occurring around the electric power connection to the motor. There may be some current leakage occurring to promote this effect, although it might be expected that the RCD device would intervene. Considering the total volume of the three pools being supplied, and an estimate of the flow output from the pumps, it is estimated that the average turnover would be approximately 5 .7 hours. ( based upon an estimate made before the actual pump curve was sighted ). To clarify these matters would require a field based investigation; potential energy savings would warrant such action. System 2 supplies the intermediate and toddlers pools. The pump for the system is the Southern Cross designated 125 x 80-120 driven by an electric motor. Again working from the Southern Cross pump range chart, it is estimated in this operating environment that the output would be 28 L per second. The level of equipment attaching to this unit is similar to that applying in system 1. Considering the total volume of the two pools supplied, it is estimated that the turnover rate on average would be about 2.3 hours. 3.4 Filtration System 1 - provided by 5 No Astral filters in parallel. These units are 2350 mm diameter, with a filtration area of 4.34 square metres. According to the nameplate on the filter, the rated filtration performance is 30m/hr. This is lower than some of the competition filters. For the assumed flow rate from the pump system, the filtration rate is estimated to be less than 20 m/hr, or 20 cubm/sqmfilterarea/hour. The filters should be operating comfortably within their range. System 2 provided by a single Astral filter. The unit is identical to the filters used in system 1.

15

For the assumed flow rate from the pump system, the filtration rate is estimated to be 24 m/hr. Again comfortably within the allowable operating range. Both filtration rates are relatively conservative, which is appropriate for the filtration of heated water, although it is understood that the usual operating temperature is 26°C. 3.5 Disinfection Disinfection is by the injection of sodium hypochlorite into the Filtered Water Return after filtration. Carbon dioxide is used for ph correction. The disinfection system is controlled by two chemical control stations located in the pump room. Each of these controls consist of a Prominent DSR controller with the appropriate sensors. Chemicals are held in a separate storage building to the east of the filters, and the hypochlorite input delivered to each system by separate Prominent chemical pumps. The sodium hypochlorite is stored in a 3000 L polyethylene tank. A concrete hard stand/spill containment is in front of the building for the tanker unloading. 3.6 Pool Water Heating A fairly sophisticated pool water heating system is in place. It is centred around two Ray Pak gas heaters with capacity of 720 kW, and a primary heating circuit feeding two separate heat exchangers for each of the 2 pool systems. The primary circuit is a pumped continuous hydraulic loop providing the heat input to heat exchangers for transfer to the FWR returning to the pools. There were no external signs of any problems in the system. It is understood however, that there may be a difficulty in obtaining sufficient heat input to the intermediate and toddlers pool in cooler weather. This may be due to exchanger capacity, although there may be other factors to do with fluid transfer that could affect the position. Some diagnostic work would be necessary to clarify the reasons for this issue. Given the relatively high energy inputs required, some investigative work with instrumentation would be warranted. 4.0 Buildings All the buildings appear to be relatively new excepting for the small building containing the pump for the slide water recirculation.

16

Main Building The main building on the Barnard Street frontage is contained on two levels, with the various amenity and other functions required for the operation of the facility. Externally, the wall construction shows the use of some exposed brickwork, along with rendered surfaces (likely to be concrete masonry). The structural system for building appears to be reinforced concrete with concrete floors apparent at each level. Roof cladding is colour bond steel. Access to the building from Barnard Street occurs directly to the upper level via a tiled entranceway. A window wall style entry provides access into the foyer. There are two offices opening from the foyer opposite the entry control point. A partition wall separates the two. Otherwise walls are concrete masonry. Entry to the facility is obtained by proceeding to the balcony area extending from the upper level offices and the kiosk/kitchen. The upper level offices provide for the facility management and have direct access to the balcony area and thence to the various activities centres. These are well fitted with contemporary finishes all in good condition. The kitchen area is largely tiled and equipped with extensive stainless steel appliances and the like. It opens to the balcony via a roller shutter servery. All this in good condition. The balcony is fully tiled, with a stainless steel protective fence around the perimeter. Access goes to the lower level by either of two stairways (tiled) and also a ramp access designed for persons with limited mobility. It also has stainless steel railing. At the time of inspection, the nonslip floor covering on the ramp was largely unserviceable. At the time of writing, it would be expected that this issue would have been addressed for the swimming season. At the lower level, the essential provision is for the dressing rooms and associated amenities. A defect was noted near the southeastern corner of the building where cracks in the render indicated some sort of distress in the underlying concrete masonry. It is possible given the location that there may be some settlement occurring on this corner. The cracking could be measured and the position monitored over a period of time before considering possible remedial action. Adjacent to the defect area, there is a staff amenities area fitted out with some basic facilities. Painted concrete masonry walls. Immediately adjoining a first-aid room fitted with the appropriate equipment. Along the corridor, there is a store room for pool operational equipment. It is has concrete slab floor with painted masonry walls and a concrete underside to the upper floor.

17

The female dressing rooms and amenities are all finished to a high standard, as is the Male provision. Provisions for Female are as follows: 6 No W/C 6 No showers 4 No hand basins It was noted that there are some losses to the finishes on the W/C partitioning. Also a tap missing from one of the showers. The Male dressing rooms provision as follows: 2 No W/C 1 No urinal 4 No communal showers 2 No partitioned showers 3 No hand basins Noted some deterioration of the joint between wall and floor in some parts. Some general tile grout deterioration of a similar nature. Soap holder missing from one shower. Some losses to the finishes on the W. C. partitioning. Family room -- contains the full complement of disabled persons WC and shower, as well as a baby's change table. In good condition. Store room -- further provision for various storage requirements. Water storage heaters also contained in this area. Plant Room The Plant room is on two levels, constructed in reinforced concrete and concrete block masonry. There are no additional finishes either internally or externally. All in good condition. Chemical Storage Room Also constructed in concrete masonry on a concrete slab, Sarked timber framed roof with galvanised steel roof cladding. In good condition. Slide pump Shed This galvanised steel panel clad structure has a steel frame. In this environment the frame showing fairly heavy corrosion. Will need to be considered for replacement in the medium term.
