Overview of WSAA

The Water Services Association of Australia (WSAA) is the peak industry body that supports the Australian Urban Water Industry. Its members and associate members provide water and sewerage services to approximately 20 million Australians and many of Australia’s largest industrial and commercial enterprises.

The Association facilitates collaboration, knowledge sharing, networking and cooperation within the urban water industry. It is proud of the collegiate attitude of its members which has led to industry-wide approaches to national water issues.

WSAA can demonstrate success in the standardisation of industry performance monitoring and benchmarking, as well as many research outcomes of national significance. The WSAA Executive retains strong links with policy makers and legislative bodies and their influences, to monitor emerging issues of importance to the urban water industry. WSAA is regularly consulted and its advice sought by decision makers when developing strategic directions for the water industry.

WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information relating to the provision of urban water services between industry, government and the community, and to promote sustainable water resource management.

The Association’s main activities focus on four areas:

1. Influencing national and state policies on the provision of urban water services and sustainable water resource management;

2. Promoting debate on environmentally sustainable development and management of water resources and the community health requirements of public water supplies;

3. Improving industry performance and establishing benchmarks and industry leading practices for water service processes; and

4. Fostering the exchange of information on education, training, research, water and wastewater management and treatment and other matters of common interest

Cover is locked into the frame using polymer locks with SS316 fastenings to ASTM 240/240M. The frame and makeup rings are held down by 4 x10mm threaded rod SS316 fastenings supplied by Tri Underground Australia’s normal suppliers of bolts.

7.2.3.4 Cover Lifting Keyhole


The cover lifting keyhole is 60 mm from the edge (not 35mm). Given the light weight of the cover Tri Underground Australia do not think this should be an issue which has not been raised as a concern from those two Water Agencies (Sydney Water Corporation or City West Water) who conducted field trials. The two Water Agencies SWC and CWW have already approved the product.

The lifting keyhole is designed a little larger than in Figure 3.1 of AS 3996:2006 to give slightly more clearance for Gas Air Tight lifting tools, hence creating a friendlier inlet for the user. The secondary key used (mainly in QLD) is Tri Underground’s T Piece lifting key. These keys are used by the likes of Transport of Main Roads & Brisbane City Council for a similar cover. The lock has a built-in friction ring which makes it difficult to turn with generally available hand tool such as screwdriver and of course the ‘O ring’ on the lid creates some friction when trying to get the lid out of the ground.

The inlet of the locking cap is sealed by a Rubber Cap that has a tight male-female fit in the keyhole inlet, hence adding further protection to the keyhole inlet from dirt, high heels, children’s fingers etc.

Refer to Appendix E for Product material specification for Rubber Cap with Seal.

If the inlet is exposed, finger strength alone from a child would not be enough to turn the T Piece locking Mechanism. The cover is 10.2 Kg and rests in the rebate of the collar; hence a locking key is also used as a lifting key. The cover is not designed to lift out using hands / fingers.

7.2.3.5 Freedom from Defect


Covers are inspected after manufacture to ensure compliance with Clause 4.6 of WSA 133.

7.2.3.6 Cover Deflection and Permanent Set


Cover/frame assemblies shall meet the requirements specified in Table 4.2 when tested in accordance with

Appendix C of AS 3996:2006 using the serviceability and ultimate limit state design loads nominated in

Table 3.1 of AS 3996:2006, as well as the high temperature and sustained load tests specified in Appendices

B and C of WSA 133.

TABLE 4.2 - LOAD TESTS AND DEFLECTION LIMITS

Ultimate limit state design load - -

High temperature Appendix B (WSA 133) CO/100 -

Sustained load Appendix C (WSA 133) CO/100 -

Refer to Appendix A2 for copy of the type test result issued to Tri Underground Aus. Pty Ltd by Structural Testing Services, Toowoomba QLD 4350, Report ID STS-09-167 dated 7/10/2009. This report shows the following:

At the serviceability design load a measured deflection of 5.3mm vs. the requirement of CO/100 = 6.0mm maximum (where CO = Cover Opening, i.e. 600mm).

A permanent set of 2.4mm vs. the requirement of CO/250 = 2.4mm maximum.

The cover was able to withstand the ultimate load at the 80kN without failure.

In addition the following three reports included in Appendix A2 are applicable.

OPUS International Consultants Ltd dated 4/7/2012 summarising the load test result as detailed above (one report).

Proline Plastics Ltd dated 17/8/2012 describing test results for 50kN for 24 hours and 50 degree C for 2 hours (two reports for high temperature and sustained load).

7.2.3.7 Impact Resistance


When tested in accordance with Appendix D, covers shall show no visible cracking on either side of the cover

and with no indentation exceeding 5 mm depth.

Test Procedure: The cover was placed inside its supporting frame on a concrete floor. The four most vulnerable

points of the cover surface between strengthening ribs were identified and marked. The striker was dropped

from 2.5 m on to the marked points in the four different locations. The cover was inspected for cracking or

structural damage. After an hour the depth of the indentation was measured.

Refer to Appendix A4 for the ‘Impact Test Report’ prepared by Proline Plastics Ltd dated 27 March 2013.

Test Results: No visual sign or cracking or structural damage. The Indentation Depths at the four most vulnerable points are 3.9 mm, 4.2 mm, 4.9 mm and 4.1 mm which are less than 5 mm.

Hence the product does comply with the requirements of the standard AS/NZS 1462.3:1998.

7.2.3.8 Gas-Tightness of Cover/Frame Assembly


The TRIGATC & F cover and frame assembly was prepared for testing by the Opus International Consultants Albany Laboratory in accordance with AS 3996 Appendix ‘F’ (Gas-tightness)

Water was ponded 5 mm above the cover assembly. Air was pumped into the cavity of the assembly at a pressure of 0.5 kPa and maintained for three (3) minutes. The result indicated there were no leaks/air bubbles. There was no change in water height in the manometer apparatus. The applied pressure was maintained during the test. No drop in air pressure or visible escape of air was observed during the gas-tight test.

Refer to Appendix A5 for test report (Job No. 1-L0142.69 dated 28/10/2014) issued to Proline Plastics by Opus International Consultants Ltd Auckland Laboratory.

7.2.3.9 Water-Tightness of Cover/Frame Assembly


The TRIGATC & F cover and frame assembly was prepared for testing by the Opus International Consultants Albany Laboratory in accordance with AS 3996 Appendix ‘E’ (Watertightness)

A water retaining structure was erected around the perimeter of the assembly and filled with water to a depth of 150mm, the level marked, and maintained for 10 minutes. The TRIGATC&F cover and frame were found to be watertight. The test results reported No leaks could be seen visually & there was no change in the height of water. No air-bubbles were present during the test. After the 10min the cover & frame were moved to check for leaks underneath, the position was still completely dry.

Refer to Appendix A6 for test report (Job No. 1-L0142.69 dated 28/10/2014) issued to Proline Plastics by Opus International Consultants Ltd Auckland Laboratory.

7.2.3.10 Marking

Ref: Clause 5 of WSA 133

Tri Underground Australia fully complies with the marking requirements of WSA 133. Refer to Appendix J for current marking on Tri Underground Australia Lightweight cover.

7.2.4 Informal Confirmatory Tests

7.2.4.1 Pentair Water Solutions

Pentair have done some informal confirmatory testing such as ‘Access Cover Hold-down System Assessment’ to sustain the defined surcharge pressure of 50 kPa. This is part of Pentair’s desktop engineering review to ensure that the cover would meet the pressure requirement.

Refer to Appendix A7 for details of this test.

7.2.4.2 Proline Plastics Ltd

Refer to Appendix A8 for details of gas and water leak tests and other visual inspection tests carried out by Proline on Pentair lids prior to despatch.

8 WSAA NETWORK REQUESTS

Question 1: Is the key a ‘Gatic key’ or the same as ‘Terra Firma Composite Fibreglass Pit Lid’? We do not want 50 different types of key for ‘Network Operations crew’ to carry around.

Answer 1: A standard T-Bar lifter is used with the Pentair Access covers and it is also used to lock it. It is the same lifter that is used for lifting concrete centre lift covers. The prime use of the Pentair lightweight covers is for use where concrete covers would traditionally have


COPYRIGHT

been used. Hence the key used is the same as that normally used for concrete access covers and complies with WSA 133 and AS 3996. Figure 2 of the appraisal report shows a photograph of a typical Pentair key.

The Pentair key is different from the Gatic key. The Gatic Key is too wide to fit into the Pentair lifting slot. We do not know the shape of the ‘Terra Firma’ key, hence cannot comment on that.

Question 2: The 20 year life expectancy is a concern. I suspect a 20 year life would not be acceptable to City West Water (CWW). Depending on cost, ease of replacement and how they will fail, this may be a significant issue. In what way are the covers likely to fail in 20 years? Could a failure be dangerous?

Answer 2: Clause 2.2 of WSA 133 requires that suppliers demonstrate that Access covers have a 20 year minimum life when exposed to ultraviolet radiation. We (Pentair) have now submitted test data to demonstrate a 100 year service life.

Question 3: Can we get a phone signal through these covers? If so we might use them for RTU pit covers.

Answer 3: We (Pentair) have no information on that subject.

Question 4: Suggest such a lightweight cover must be lockable; otherwise kids could remove them easily.

Answer 4: WSA 133 requires that Access covers be lockable and the Pentair Access cover is lockable using the key for either Pentair or concrete covers.

Question 5: Is the Pentair lightweight access cover only made in Class B?

Answer 5: Pentair Access Covers are only supplied to WSA 133, which is only for Class B Access covers.

Question 6: Pentair Class B Access Cover is not subjected to traffic so EPDM seal should last?

Answer 6: EPDM seals are commonly used for both potable water and sewer applications in the water industry where they have an expected life in excess of 100 years.

Question 7: I refer to the WSAA Member Alert dated 29 May 2014 requesting peer review of Product Appraisal Report PA 13/26 for the Pentair Water Solutions PENTGATC Lightweight Circular Lockable Composite Access Cover and Frame.

I have reviewed both the Draft Appraisal report and Addendum documents dated 29 May 2014 and support the recommendations set out in the Executive Summary for use on Gravity Sewerage Maintenance Hole structures. The technical and product related content (including type testing reports) provided in both documents are complete and there is nothing additional that requires inclusion from my perspective. On a very minor point, I would suggest using the term ‘Maintenance Hole’ in lieu ‘Manhole’ which is currently referenced in three sections of the report; Pages 6, 9 and 18. The Pentair Technical data sheet (Appendix B) also references ‘Sewer Manhole cover’.

Answer 7: We (Pentair) agree that the term ‘Maintenance Hole’ is more appropriate than ‘Manhole’. It can be replaced in the three sections of the report. It will be changed with the next revision of the Pentair Technical data sheet.

Question 8: A general enquiry that I had was whether Pentair have indicated further development of their Circular Lockable Composite Access Cover and Frame to include a Class D rated version?

Answer 8: At present Pentair only has a lightweight Class B cover. We (Pentair) are not working on a Class D cover at present.


COPYRIGHT

Question 9: ACTEW’s safety personnel have advised me that clear opening of 600 mm is too small for satisfying our obligations under OHS legislation which these days includes rescue as well as access.

Answer 9: As far as we (Pentair) know 600 mm openings remain a commonly used access opening in the water industry in Australia. Pentair’s lightweight cover significantly improves OH&S risks due to their light weight for both replacement of old/failing concrete covers and for new installations.

9 FITTING INSTRUCTIONS, TRAINING AND INSTALLATION

15 WATER AGENCY EXPERIENCE WITH THE PRODUCT OR FIELD TESTING REPORT

15.1 Sydney Water Corporation Field Trial

A field trial installation of lightweight macro-composite maintenance hole cover supplied by Pentair, was carried out by Water Infrastructure Group and supervised by Sydney Water (represented by Jerry Sunarho, Standard Engineer) on 30 January 2013 at 3 Loch Maree Place, Vaucluse. (Sydney, http://goo.gl/maps/dyfEo).

The trial installation was successful. The location was in one of SWC customers’ backyard with restricted access. This situation usually means occupational risk to SWC field crew and contractors, who have to manually carry the traditional heavy maintenance hole cover and concrete make-up rings. This risk became negligible with the use of lightweight cover and polyurethane rings. In addition, it also made the installation quicker, which means less interruption to SWC customer.

A YouTube video of the installation can be accessed at http://youtu.be/1tEkFHjTgno.

15.2 City West Water Field Trial

The field trial conducted using Pentair lightweight cover and frame within CWW licensed area was successful. The cover and frame was installed on 27th November 2013 as replacement to an existing defective square concrete cover and frame. The site address is 8 Govan Court, Footscray VIC 3011 residential area within the Western suburbs of Melbourne. Refer to Appendix L for the field trial report.

The staff(s) mentioned in Table 3 can be contacted to get further information of the product and its installation.

16 DISCUSSION

Issue 2 of this Product Appraisal Report replaces and updates PA 1326 Issue 1 published on 26 June 2014.

Clause 2.2 of WSA 133 requires appropriate evidence of the suitability of the material to resist ultraviolet radiation for a minimum 20 year life when exposed to direct sunlight shall be provided. Tri Underground Australia lightweight cover is made of Polycarbonate Composite Material plus Stainless Steel 316 sub-frame and the frame is made of Polypropylene. Issue 1 has provided 3000 hr UV exposure test result to demonstrate a minimum of 20 year life be achieved.

Issue 2 includes two reports pertaining to Longevity and additional UV assessment on Tri Underground Australia lightweight cover to demonstrate that a service life in excess of 100 years can be expected, instead of a minimum of 20 year life. Issue 2 also resolves Future Works identified in the previous version.

The following amendments have been made in Issue 2:


COPYRIGHT

a) Completion of Future Works

Additional markings to the cover with ‘WSA 133’ and ‘sealed’ on the outside as shown in Appendix J.

Tri Underground Australia has changed the gasket supplier from the foam gasket provided by C Tech (NSW), to a soft solid gasket provided by Gulf Rubber who has StandardsMark product certification to AS 1646:2007 Elastomeric seals for waterworks purposes as shown in Appendix C. Pentair has also submitted new Opus test certificates for Water and Gas tightness testing of the new rubber, demonstrating its suitability. Refer to Appendices A5 and A6 of Addendum to the main report for these test results.

Tri Underground Australia has submitted the Installation Instructions for the cover and frame as shown in Appendix M.

b) Life Expectancy of the cover

Two reports were included to demonstrate the Cover’s service life in excess of 100 years:

Longevity of Tri Underground Australia Access Cover, Pentair Report PT 15287 dated 31/07/2014 as shown in Appendix A10 of the Addendum to the main report.

Additional UV Assessment of Tri Underground Australia Access Cover, Pentair Report PT 15293A dated 27/08/2014 as shown in Appendix A11 of the Addendum to the main report

Examination of all of the submitted documented material provides an expectation that the Lightweight Circular Lockable Composite covers and frames described here and manufactured and distributed by Pentair Water Solutions are ‘fit for purpose’ in gravity sewer networks.

17 LIFE EXPECTANCY

Minimum life of Maintenance Hole Cover is 100 years. Polycarbonate Composite material plus 316 SS Frame to give strength and support. UV testing to 3000 hours has been completed and test results are included in Appendix A1 of Addendum to the main report.

Further details substantiating a 100 plus year service life claim are provided in Appendix A10 (Longevity of Pentair’s Access Covers) and Appendix A11 (Additional UV Assessment of Pentair’s Access Cover) of Addendum to the main report.

WSA 133 requires that covers demonstrate that a 20 year life be achieved, and this has been done, however a life of up to 100 years is preferred by some potential users.

17.1 Longevity of Pentair’s Access Cover

The report in Appendix A10 assesses the expected life of Pentair’s Access Cover by assessing the factors relevant to longevity (i.e. creep, corrosion and polymer deterioration due to ultraviolet ray), further evaluating the ultraviolet ray resistance, and detailing additional testing undertaken.

17.2 Additional UV Assessment of Pentair’s Access Cover

The report in Appendix A11 assesses additional UV exposure data recently provided by Clariant on the PC / PBT alloy cover material.

To demonstrate a minimum of 20 year service life, Clariant has originally provided a report as shown in Appendix A1 on the UV exposure and impact resistance results by exposing the cover for a total of 3,000 hours. Clariant have now extended the testing period to 8,250 hours to demonstrate that a life in excess of 100 years can be expected.

18 FUTURE WORKS

Pentair Water Solutions has fully complied with all Future Works specified in the original appraisal and no Future Works are required.
