1 EXECUTIVE SUMMARY

Aquatec Fluid Systems specialises in the supply of FRP (Fiber-reinforced Plastic) Packaged Pumping Stations and Emergency Storage Tanks for individual council or Water Agency requirements across Australia.

Aquatec supplies an extensive range of fibreglass vessels for underground applications as part of their packaged pump stations and emergency storage tanks. Aquatec has its head office and factory at 2 Provincial Crescent, Shepparton VIC 3630.

The Aquatec FRP Packaged Sewage Pumping Stations are available in various sizes from 1200 mm to 6000 mm in diameter and from 1 m to 15 m in depth.

The Aquatec FRP Emergency Storage Tanks are available in various sizes from 1000 mm to 6000 mm in diameter and from 1 m to 25 m in length.

However for the purposes of this appraisal WSAA has elected to assess the performance of FRP pumping stations up to 4000 mm in diameter and 10 m in depth; and for FRP Emergency Storage Tanks up to 4000 mm in diameter and 20 m in length.

Aquatec’s FRP pump stations and emergency storage tanks are manufactured as a one-piece construction to exact project specifications of the clients and delivered to site as a complete unit with a simple installation process. All joining of internal components is carried out as part of the manufacturing process in the factory. No onsite joining or sealing is required.

Aquatec can deliver FRP packaged pump stations as a single unit (i.e. wet well with an integral valve chamber) or wet well with an external valve chamber. Aquatec’s FRP pump stations and emergency storage tanks can be engineered to withstand internal and external loadings across all ground conditions.

Aquatec offers support to the Consultants and Contractors on all aspects of design, supply, installation and maintenance. The project consultant and/or Water Agency are responsible for determining the suitability of the station design for the local ground conditions.

A range of options and accessories, offered at fit out are outlined in this appraisal to demonstrate product versality but are not intended to be included in the appraisal. The project constructor will need to ensure that the specifications for covers, pumping equipment, electrical controls and cubicle comply with relevant project documentation based upon the individual council or Water Agency standards. Each station can be designed to accommodate multipart cast iron Class B or Class D covers or aluminium covers.

The FRP vessels are designed to meet the requirements of:

• AS 2634:1983 Chemical Plant Equipment made from Glass-Fibre Reinforced Plastics (GRP) based on thermosetting resins;

• BS 4994:1987 Specification for design and construction of vessels and tanks in Reinforced Plastic; and

• AS 2566.1:1998 Buried flexible pipelines, Part 1: Structural design

Two types of joints to external services are used; (a) Socket connections for PVC-U fittings; and (b) Flange connections for all other materials.

FRP Pump Stations and Emergency Storage Tanks are assembled in a controlled factory environment. Aquatec’s quality management system has been audited to AS/NZS ISO 9001:2008 by Qual-Safe Management Systems 'Certificate of Compliance' No 121412.

Aquatec’s designs, manufacturing process and products are certified as required by an independent composite engineering organisation with a registered Professional Engineer in QLD.


COPYRIGHT

Aquatec has submitted ballast calculations for a 4 m dia x 10 m deep FRP pumping station and a 4 m dia x 20 m long FRP emergency storage tank. Aquatec’s consultant LAURIE McGOLDRICK Consulting Engineers (LMCE) has done these calculations for “worst case scenario” (i.e. empty FRP vessels installed in a ground where water table is at the surface level) to demonstrate the total uplift forces (i.e. buoyancy) are balanced by the total resisting forces (i.e. self-weight of FRP vessel, backfill and concrete) incorporating safety factors. A safety factor of 1.2 and 0.9 are used for uplifting forces and resisting forces respectively. Refer to Appendix D for the computations.

Aquatec has also submitted installation manuals for both pump stations and emergency storage tanks of smaller sizes than the above models (i.e. 4 m dia x 10 m deep pump station and 4 m dia x 17 m length) with a recommendation of the following generic formula for ballast calculation:

Chamber Volume in m3 ÷ 2.2 = Volume of Concrete Ballast Required in m3

Refer to Appendices A8 and A9 in the Addendum No. 2 to the main report for the installation manuals.

Although the above formula has a substantial safety factor built into it, Aquatec prefers designing each pump station or emergency storage tank, on a case by case basis as per Client’s requirements. This ensures accurate computations are undertaken based on actual site conditions which eliminate any excess concrete used.

Aquatec manufactures solid FRP wall pump stations, with the addition of composite structural stiffening ribs as and when required. The design thickness and manufacture methodology is supplied by Aquatec’s Composite Engineer.

The FRP vessels used in the Aquatec FRP packaged pump station and emergency storage tanks have been assessed in line with WSA 129:2011 Industry Standard for Plastics Collection Tanks for Pressure and Vacuum Sewers.

Aquatec performs the following quality tests to ensure the FRP vessels are constructed in line with AS 2634:

a) A third party Composite Engineer performs visual inspections of completed FRP vessels when required.

b) The Engineer can also provide a verification statement for each completed FRP vessel based on a review of working drawings, the finished product inspection and drawings of the finalised specifications. The design verification statement can cover:

• Performance against design

• Structural conformity to design

• Compliance with AS 2634:1983

• Fitness for purpose

c) At completion of each FRP vessel, a quality inspection is performed by Aquatec’s in-house Engineer using a quality checklist that ensures the vessel meets all required design standards.

d) Pressure tests are performed on the internal pipe work and fittings of each completed station depending on Customer request.

e) Aquatec conducts ‘type tests’ as per Clause 10.1 of WSA 129 as detailed in Table 5.

The requirements of this appraisal have now been met with respect to general design requirements, product type testing, auditing of production quality control systems, review of documentation and guidance for designers, installers and operatives and the products are seen as 'fit for purpose'.

3.1 FRP Vessel The FRP unit is manufactured by hand and machine and is constructed as follows:

Internal Corrosion Barrier

• Contact Molded – “C” Glass layer with 0.5mm thick Vinyl Ester Resin 90%

• Backing layers – 2.0 mm thick layer of Vinyl Ester Resin with “E” Glass 70%.

Structural Matrix

• Structural – “E” Glass reinforcement in rovings in continuous strands and isophthalic Resin.

• Reinforcement –composite rib formers overlaid with “E” Glass reinforcement.

External Surface

• “C” Glass layer with 0.5mm thick Isophthalic Polyester Resin

• Sealer – High performance applied ISO/NPG Flowcoat for external finish and seal.

3.2 FRP Vessel manufacturing method The barrels are filament wound, with bases and tops contact moulded by hand laying sections and machine sprayed layers, with the very large bases reinforced with layers of a special reinforcement as specified by the Composite Engineer’s design.

Structural resin is ISO Polyester with corrosion barrier Vinyl Ester resin. The structural fibre is ‘E’ glassfibre in varying thicknesses and weights to suit design requirements. Aquatec’s Composite Engineer specifies the thicknesses of each component and the number of layers including the type of resin and glassfibre to be used.

3.3 Thickness of the corrosion barrier to FRP exposed surfaces A minimum of 2.5 mm thickness is required as a corrosion barrier and this is reinforced with a product called Veil to prevent any cracking of the Vinyl Ester resin.

3.4 Jointing options The FRP packaged pump station is supplied as a complete unit. All joining of internal components is carried out as part of the manufacturing process. No onsite joining or sealing is required as the pump station is a one piece construction and delivered as a complete unit to site with a simple installation process.

Two types of joints to external services are used; (a) Socket connections for PVC-U (Series 1 & 2 and DWV) fittings; and (b) Flange connections for all other materials.

The following jointing options are available (spigot, socket, flanged) for PVC-U DWV, PE, VC, PP and GRP pipework:

• PVC-U DWV Spigots and Sockets are bonded in place using a proprietary resin system that meets and exceeds the requirements of BS 4994 and is compatible with glass resins, so inlet/outlet using this pipe material is installed as per the clients’ specification.

• PE, VC, PP and DICL or any steel items are not compatible with glass resins for a number of reasons, especially the different rates of expansion and contraction of these


COPYRIGHT

materials, causing cracking around the joint over time and allowing the connection to leak. To overcome this potential problem, Aquatec installs FRP flange pipe sections either as Flange/Spigot or Flange/Flange sections to suit the application required.

• GRP pipe work can be built in within the FRP barrel.

3.5 Access Covers and safety grates Aquatec standard covers are hinged 6 mm aluminium checker plate Grade 5052 in H32 temper with triple grip finish that are light to lift and cannot fall into the wet-well or valve pit.

The covers can be padlocked shut and fitted with an optional step down aluminium safety grates to allow inspection and hose down or even float switch replacement without risk to service personnel.

The covers are sized to suit the pump and valve access requirements and the hinge assemblies and step down.

The access covers and safety grates shall comply with specific requirements of some water agencies to be allowed for use in their licensed area such as City West Water (CWW) Supplementary Manual to the WSAA Sewerage Pumping Station Code (WSA 04-2005:2.1), Version 2.4.

4 SCOPE OF THE APPRAISAL The scope of this appraisal is limited to the range of Aquatec FRP Sewage Pumping Station and Emergency Storage Tank referenced in Section 3, Valve Chamber and Access Covers. The range of optional accessories (fit-out) are discussed in Clause 6.2.6 and 13 to demonstrate product versatility but not intended to be included in the appraisal as they are usually supplied to individual agency specification.

Aquatec offers an extensive range of optional accessories, offered at fit-out as detailed in Section 13. The extensive range of optional accessories includes mechanical, electrical and SCADA equipment which can initially be reviewed by individual water agency on a case by case basis. These options are not included in this assessment.

This appraisal covers FRP pump station and emergency storage tank packages used in alternative water supply (Stormwater) and Sewerage (pressure sewer and gravity sewer) applications. Only the wet well, valve chamber and covers are being assessed.

5 APPRAISAL CRITERIA Appraisal criteria is determined by the WSAA Infrastructure Products and Materials Network and regularly reviewed to ensure that the criteria reflect the requirements of WSAA members.

The FRP pump station and emergency storage tank have been assessed in line with WSA 129:2011 Industry Standard for Plastics Collection Tanks for Pressure and Vacuum Sewers.

5.1 Quality Assurance Requirements The WSAA Infrastructure Product and Materials Network accept FRP components manufactured and supplied under cover of a certified ISO 9001 management system. The scope of the certification shall include “Manufacture and supply of FRP to AS 2634:1983 (or similar).

5.2 Performance Requirements 5.2.1 Product Manufacturing Standards There is no specific Australian or International product standard that provides manufacturers, designers and installers with a document that outlines the specific criteria


COPYRIGHT

for the manufacture of FRP vessels for sewerage applications, applicable to the scope of products covered by this appraisal.

WSA 129:2011 is a WSAA Industry Standard that specifies the design, manufacturing and performance requirements for manufacturers of plastics collection tanks for storage of sewage in pressure and vacuum sewerage systems and which are specifically designed for buried installation. This standard specifies performance requirements for Glass Fibre-Reinforced Plastics as the material for collection tank.

Until such time as an appropriate Industry Standard, Australian or International Standard is developed which specifies the • requirements of FRP chambers; • the minimum requirements for the materials to be used in, and the manufacture of; and

controlled quality FRP chambers components; and • includes descriptions of methods of sampling and testing of components.

the performance criteria defined in Sections 5.2.1, 5.2.2, 5.2.3, 6.2, 7.1, 7.2.1, 7.2.2, 8.1, 8.2, 9.1.2, 9.1.3, 9.1.4, 9.2.1, 9.2.2, 10.1.1, 10.1.2, 10.1.3, 10.1.4, 10.1.5, 10.1.6, 10.2.1, 10.2.2, 10.2.3 and 11 of WSA 129 shall be applied, noting that FRP chamber / vessel being assessed is not a pressure vessel (i.e. pressure or vacuum sewer).

Aquatec uses the following standards in the design and manufacture of their FRP vessels:

• BS 4994:1987 Specification for design and construction of vessels and tanks in reinforced plastics

• AS 2634:1983 Chemical plant equipment made from glass-fibre reinforced plastics (GRP) based on thermosetting resins

• ASME RTP 1:2013 Reinforced Thermoset Plastic Corrosion-Resistant Equipment

• EN13121:2008 GRP tanks and vessels for use above ground - Part 3: Design and workmanship

• AS 2566.1:1998 Buried flexible pipelines, Part 1: Structural Design

Aquatec uses other relevant standards and provide engineering computations to the client as part of an Engineering and Quality Assurance package. One area that may be worthwhile investigating is the use of a ‘Category Table’ as detailed Table 3 (Reference: Clause 5 – Categories of Tanks and Vessels in BS 4994, Table 2) where it is possible to ascertain the level of engineering required for a particular type of vessel and its end use.

This will allow for cost effective design for any given situation and maximise the level of engineering where required (i.e. in pressure vessel situations) and reduce engineering design costs where possible (i.e. in non-pressure situations).

6.1.2 Suppliers for Wet-well and valve pit access covers Aquatec supply single and multi-part solid-top or recessed (with concrete infill) cast ductile iron access covers and frames for their range of FRP Sewage Pumping Stations and Emergency Storage Tanks. Single and multi-part solid top access covers and frames have been appraised for compliance with AS 3996:2006 Access covers and grates. NOTE:1 It is recommended that access covers and frames be supplied under cover of an ISO Type 5 Product Certification scheme administered by a JAS-ANZ accredited conformity assessment body.

Class D and B covers and frames are provided as access points in trafficable and non-trafficable areas, respectively.

The aluminium access covers for the wet-well and valve chambers are designed and fabricated by Aquatec. Aluminium is commercial grade 5052 in H32 temper with triple grip finish. The aluminium access covers are not designed for vehicle loads.

Aquatec has advised that in line with current trends, pumping stations are rarely located in trafficable areas and ductile iron covers are therefore not normally fitted. Aquatec advise that some ductile iron covers exceed OH&S maximum lifting limits and pose other safety risks to service personnel.

Aquatec has submitted detailed drawings covering the design and fabrication of the lockage aluminium hinged lids, including the galvanised swing up safety grate. The cover is manufactured from 6 mm (min) aluminium checker plate with recessed hinges and lifting handles. Hinged safety grates are mounted below the cover to prevent operators accidentally falling into the wet-well. The individual covers are opened only during pump removal. The covers are sized to suit the pump and valve access requirements and the hinge assemblies and step down frame is cast into the cover slab.

Aquatec assemble an EPDM rubber odour seal to the frame edging under the cover. Aquatec advise that their aluminium covers are water and gas tight. The cover slab is set above ground level if rainwater surface infiltration is likely. The height of the cover slab above ground level is specified on the Project Drawings to conform to the Water Agency requirements.

Aquatec have indicated that aluminium post inserts for corner posts for rail safe telescopic guardrail system can be cast into the cover slab or mounted underneath the cover.

Aquatec aluminium covers, when subjected to centrally placed load of 120 kg, did not exceed the 20 mm deflection of the cover, as specified in Clause 5.8 of the Sewage Pumping Station Code of Australia, WSA-04-2005.

Aquatec safety grates can be made to order with a suitably located lockable access point and cover of minimum size 300 mm x 300 mm to allow easy access for maintenance of all level sensing equipment. Safety grates are provided as standard on all Aquatec pump stations.

The aluminium cover design allows the cover to be opened fully and laid flat. For valve chamber depths greater than 1.5 m, Aquatec recommend safety grates.

FIGURE 4: ELECTRICAL CONDUITS THROUGH FRP WALL FOR CABLING 6.2.5 Ballast Design and Computations All underground structures are subjected to hydrostatic loading in presence of ground water. Where this loading is greater than the self-weight of the structure it is possible the structure could move due to buoyancy forces. There are numerous ways the potential movement due to buoyancy can be eliminated, which include:

• Placement of backfill material either concrete, soil or a combination of both over or around the structure to act as ballast against the uplift forces;

• Anchoring the structure to anti floatation ring concrete slab, hold-down top pad concrete slabs or surrounding strata should suitable material, such as high strength rock, be present;

• Increasing the dead weight of the structure; and/or

• Decrease the hydrostatic loading by either removing or lowering the level of ground water around the structure.

Aquatec recommends the ballasting method to resist buoyancy forces for its FRP Pump Station and Emergency Storage Tank. In determining the ballast required for a FRP Pump Station and Emergency Storage Tank, a worst case scenario is considered based on the following conditions:

• The surrounding soil is completely saturated to the surface level resulting in hydrostatic loading of the station for its full depth;

• In determining the self-weight of the station, it is assumed any removable equipment including the pumps are not in place;

• The station is completely empty with no water / sewage present to provide downward loading;

• Backfill materials are cohesionless with no soil friction present; and

• Weight of ballast material is adjusted to take into account the hydrostatic loading on it.

The ballast calculations are based on parameters as detailed in Table 8:


COPYRIGHT

TABLE 8: PARAMETERS FOR BALLAST CALCULATIONS

Parameter Value

Density of water 10 kN/m3

Density of ballast concrete 24 kN/m3

Density of backfill (Saturated Crushed Rock) 22 kN/m3

Factor of Safety (dead load resisting floatation) 0.9

Factor of Safety (Uplift forces - buoyancy) 1.2

• Anti-floatation ring, top slab and ballast design meet Australian Standard Code AS3600, using concrete of minimum compressive strength 20 MPa.

• The FRP wet well bottom is designed to BS4994 to any resist buckling of the wet well bottom from external water pressure and internal pressure, in the installed condition with a compacted base and the perimeter of the wet well including the anti-floatation ribs embedded in concrete.

6.2.5.1 Ballast Layout

The net weight of the ballast material is to be greater than the buoyancy forces on the structure less its dead weight plus the required Factor of Safety.

The FRP packaged pump station is manufactured with an external hold down flange/s or ribs, onto which a concrete ballast slab is poured. The shape of the slab is either round or square, the selection of which is dependent on the size of the station and the surrounding conditions. The minimum depth of this slab is sufficient for the transfer of ballast loading to the hold down flange without the need for reinforcing steel. The overall depth of the concrete slab is dependent on the ballast loading required.

Above the ballast slab, compact fill is placed. The weight of material directly above the concrete slab is only considered for ballast calculation purposes.

Concrete roof slabs are recommended for all stations and the weight of these are included in the ballast calculations.

For shallow FRP structures such as standard alone Valve Pits, the weight of the roof slab generally provides sufficient ballast loading. Where additional ballast is required, thickened edge beams to the roof slab are recommended.

6.2.5.2 Computations for Worst Case Scenario

Aquatec has submitted ballast calculations for a 4 m dia x 10 m deep FRP pumping station and a 4 m dia x 20 m long FRP emergency storage tank. Aquatec’s consultant LAURIE McGOLDRICK Consulting Engineers (LMCE) has done these calculations for “worst case scenario” (i.e. empty FRP vessels installed in a ground where water table is at the surface level) to demonstrate the total uplift forces (i.e. buoyancy) are balanced by the total resisting forces (i.e. self-weight of FRP vessel, backfill and concrete) incorporating safety factors. A safety factor of 1.2 and 0.9 are used for uplifting forces and resisting forces respectively. Refer to Appendix D for the computations.

Aquatec has also submitted installation manuals for both pump stations and emergency storage tanks of smaller sizes than the above models (i.e. 4 m dia x 10 m deep pump station and 4 m dia x 17 m length) with a recommendation of the following generic formula for ballast calculation:

Chamber Volume in m3 ÷ 2.2 = Volume of Concrete Ballast Required in m3

Refer to Appendices A8 and A9 in the Addendum No. 2 to the main report for the installation manuals.


COPYRIGHT

Although the above formula has a substantial safety factor built into it, Aquatec prefers designing each pump station or emergency storage tank, on a case by case basis as per Client’s requirements. This ensures accurate computations are undertaken based on actual site conditions which eliminate any excess concrete used.

6.2.6 Attachments Aquatec design, manufactures and supplies either own stainless steel (SS) 316 ladders and brackets. Other attachments such as platforms, handrails or fiber reinforced plastic ladders can be fitted to suit Water Agency Specifications.

NOTE: The above items are not included in this appraisal.

6.2.7 Review of the documentation and guidance for designers, installers and operatives Aquatec provides customers with documents for submission of their pump station requirements, plus diagrams for customers/designers to nominate pipe positions for factory cored apertures. Also provided to customers is a list of items required to be completed prior to installation and/or commissioning of the pump station.

For further information, refer to Section 8.

7 WSAA NETWORK REQUESTS Question 1: Several concerns have been raised about resistance to flotation when installed in water charged ground. How do you address this buoyancy issue in the design calculation? Do you assume the groundwater level to exist at the surface of the pumping station as a worst case scenario? To provide additional resistance to buoyant forces, do you provide a concrete ring beam cast in situ in the base configuration? Do you undertake any additional precautions against flotation by increasing weight of precast concrete cover slab by increasing its thickness?

Answer 1: The installation of a FRP Pump Station is based on the specific project and ground conditions (questions on the existing ground conditions will be asked prior to installation) which are to be determined in consultation with a qualified civil/geotechnical engineer. To address the buoyancy issue when the FRP Pump Station is installed in water charged ground the necessary bedding, backfill, ballast, anti-floatation concrete ring (if required) and concrete cover shall be calculated to suit the individual project. Additionally, it is necessary to add water inside the wet well to counteract buoyancy until the concrete is cured or while backfilling. Aquatec does not assume the ground water level to exist at finished surface level (FSL) rather it will take this into account in the design if it was the case.

In the concrete cover slab design the necessary precautions against buoyancy are taken in the initial calculations to suit the individual project.

An anti-floatation ring cast Insitu can be utilized as a precaution against floatation which will be taken into consideration in the engineering calculations.

The cover slab and anti-floatation cover slab should not be increased without the approval of Aquatec. The pad/slabs shall be specified by Aquatec and poured by others.

Question 2: The Aquatec FRP packaged pumping station is a turn-key product. The civil contractor's main responsibilities are installation of FRP wet wells and valve pits, excavation, trenching and backfill works, water supply and site restoration.

The turn-key scope of works also includes the mechanical and electrical fit-out and overall supervision of the project from geotechnical testing of site, material delivery, attending site during installation, testing, commissioning and hand over.

Aquatec warrants the FRP Pumping Station manufactured will be free of defects in material and workmanship under normal use and service for twelve (12) months standard from installation or otherwise specified/agreed upon (i.e. negotiable).

Question 3: Is it possible for liquid to leak out of the pumping station or for groundwater to ingress?

Answer 3: Aquatec’s Fibreglass Pump Stations are manufactured as a completely sealed, one-piece vessel. All penetrations and wall fixings through the structure are carried out in the factory environment with compatible materials, allowing no chance of ingress or egress.

Wall penetrations in FRP pump wells are to be flanged FRP pipe sections incorporated permanently into the walls of the chambers during manufacture. Flanged FRP connections are required internally and externally for all classes of materials except uPVC to AS 1477 for pressure pipe and AS 1260 for non-pressure pipe (see Figure 5).

FIGURE 5: FLANGED FRP PIPE SECTION AND TRANSPORT OF FRP VESSEL Question 4: Does the aluminium plate used to fabricate the access covers and frames for wet-well and valve pit comply with AS 1734 Grade 5052 and is the design and fabrication in accordance with AS 1664? Do you consider alternative aluminium grade such as 6061 T6 and or Grade 5083 H116 to AS 1734.

Question 5: Does the welding and inspection of the above aluminium fabrication comply with the requirements of AS 1664?


COPYRIGHT

Answers 4 & 5:

The fabrication and design of the access covers and frames for wet-well and valve pit comply with WSA 04:2005 and the relevant Authority Specifications as required. Additionally, Aquatec currently have numerous Water Authorities and Council approvals.

The following Australian Standards are followed where applicable:

• AS 3996 – Class A and B certification, water tight and gas tight covers and frames

• AS 1657 - Clause 2.1.2.2 - Guardrails, allowable loads; Appendix C - Testing of guardrails, methodology; Clause 3.1.1 - Platforms (i.e. no requirement for an intermediate step); and Table A2 (i.e. minimum dimensions for aluminium guard railing)

• AS/NZS 1665 – Welding of aluminium structures

• AS 2865 – Confined spaces, general design considerations – minimum access dimensions

• AS 1319 – safety signs, confined space entry signage.

Aluminium Grade used is 5052 (marine grade). We would consider other alternative aluminium grade such as ‘6061’ if it was necessary for the project (i.e. specified in the relevant specifications).

Question 6: Does Aquatec offer a pump station design and drafting services of project specific drawings and hydraulic calculations? Or such services are done by another party?

Answer 6: Aquatec offers all pump station design including hydraulic calculations and drafting services to accommodate specific projects. We also offer design assistance if required by the consultant.

Question 7: What are the advantages of FRP Sewage Pump Stations?

Answer 7: The advantages of an Aquatec FRP Sewage Pump Station include:

• Manufactured using computerized winders with the highest grade resins and roving’s. Resins can be selected based on individual project specifications.

• Each pump station chamber can be engineered to any diameter and depth to suit project specifications and specific ground conditions.

• The FRP pump station base and sludge batter are mould formed as one piece to strengthen the overall structure, while the steep sludge batter is shaped to prevent solids build up, eliminating dead zones behind pump pedestals.

• The top cover, walls and base are glassed together to provide an impervious, holistic structure which reduces installation time.

• All chamber penetrations are incorporated permanently into the walls during manufacture to ensure no chance of egress or ingress.

• The light weight chamber reduces cranage and transportation costs.

• Fibreglass can be easily repaired compared to concrete and is not susceptible to degradation through concrete cancer, if not maintained correctly.

8 FITTING INSTRUCTIONS, TRAINING AND INSTALLATION Aquatec provide customers with proforma documents for submission of their pumping station requirements plus diagrams for customers/designers to nominate pipeline positions for location factory cored apertures. There are also documents for the customer to complete advising Aquatec of the required delivery dates and programmed commissioning dates. Aquatec also provide a checklist of items required to be completed prior to commissioning of the pumping station.


COPYRIGHT

Aquatec advises that installation is usually carried out by experienced civil contractors but the single FRP vessel design provides a simple and trouble free assembly. However, an Aquatec representative will be made available to provide specialised assistance or to oversee the installation. The pumping station is delivered as a complete unit ready to install into the excavation with instructions for installation for the civil contractor.

If required, Aquatec can also supply on-site supervision and technical assistance through to complete pumping station installation and commissioning.

At the completion of commissioning Aquatec provide the Asset Owners with Operation and Maintenance Manuals in accordance with the specified requirements. Refer to Appendix A4 in Addendum No.1 to the main report to view contents of the proposed O&M manual.

8.1 Repair Procedure Aquatec can provide ‘Procedures for repair and installation of additional fittings’ in the future, if required. These procedures have to be approved by Aquatec’s Composite Engineer who has to be advised if any of repair work has to be carried out. This would allow the Composite Engineer to make sure personnel nominated are qualified to do the work. Additional fittings installation has occurred on several occasions as well as damage repair after onsite accidents.

8.2 Maintenance Procedure Aquatec FRP stations require very little maintenance. Aquatec undertake service maintenance of their FRP Pump Station or Emergency Storage Tank as per Clients’ requirements. The FRP vessels usually require no maintenance except to wash down dust or dirt which has accumulated around the access openings. Periodic maintenance is required for the pumps and electrical equipment.

Maintenance Training: This caters for Aquatec existing personnel in need of additional assistance or new employees unfamiliar with the operation and maintenance requirements of FRP Pump Station or Emergency Storage Tank.

8.3 Training Requirements Aquatec offers training for the Civil Contractor, if required. In most occasions Aquatec representative(s) will visit the site when the FRP Pump Station or Emergency Storage Tank is being installed to ensure the job is done strictly in accordance with Aquatec Installation procedure.

Registered Training Organisations (RTO’s): Currently no RTO’s are available to provide a training program for the installation of FRP pump stations. Aquatec has a training procedure that they employ when required to check and train a new installer.

8.4 Backfill Requirements Aquatec recommends the consulting engineer conducts a site investigation to establish indicative subsurface conditions prior to the commencement of construction. Aquatec has submitted backfill requirements and construction notes for correct installation procedures. The Construction Notes are based on normal site conditions which are free of groundwater and apply to installations in cohesive and non-cohesive soils. Sites which have ground water will need dewatering for construction purposes.

The Installation procedure describes the following:

• Handling and preparation of wet well (FRP vessel)

• Site preparation

• Anti-Floatation ballast FRP Wet Well

• Bed and Backfill


COPYRIGHT

• Wet well installation with a FRP underground tank

• Piping penetrations / Fittings

• Invert

• Top pad / cover slab

• Table (FRP wet well with external anti-floatation Ribs)

In addition to Aquatec’s recommendation, the installation works shall comply with specification and standards of individual water company or local council. Refer to below link to access a sample Backfill Specification 04.03.2 published in 2013 by MRWA (Melbourne Retail Water Agencies):

http://mrwa.com.au/Documents/Standards/MRWA_Backfill_Specification_04-03.2.pdf

10 PACKAGING AND TRANSPORTATION Aquatec are responsible for packaging and delivery of the fibreglass product and components to site. The vessels are loaded onto the truck using timbers and rubbers to avoid the tray of the truck taking off the painted surface. The vessels are usually a one piece construction and are able to be transported as fully assembled.

Consideration should be given to how the FRP vessels are to be handled during loading for transport, unloading, storage, installation and removal for maintenance. Chain and wire rope should not be in direct contact with FRP. The number, position, orientation and type of lifting fittings (i.e. log or trunnion), should be determined during the design phase. Refer to Appendix I.

11 PRODUCT WARRANTY Aquatec’s Product Warranty includes the full delivery of the fibreglass vessel to site and we will also oversee the unloading, so as to not allow any damage to occur during the unloading process. Additional warranties may be negotiated on a project specific basis.
