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.

1 EXECUTIVE SUMMARY

This appraisal is for a range of Deks Industries Pty Ltd metal- banded flexible couplings with

metal shear rings in sizes DN 100 to DN 250, manufactured to AS/NZS 4327:1995 Metal-

banded flexible couplings for low pressure applications.

DEKS shear banded flexible couplings are designed for joining or repairing pipes of various

material with the same or similar nominal internal diameters, in a low pressure sewerage or

drainage pipeline systems. Where the outside diameter of the pipes to be joined is greater

than 16 mm an appropriate adapter bush is utilised to facilitate leak proof jointing. DEKS

product literature provides details of when adapter bushes are required. See Appendix A.

The range of nominal diameters covered by this Appraisal is DN 100 to DN 250 and

applicable pipe outside diameter size ranges are detailed in Section 3.

DEKS shear banded couplings are supplied with Grade 316 stainless steel metal bands,

shear rings and fasteners. The sleeve and adapter bushes are manufactured from EPDM

rubber.

The couplings are not suitable for drinking water applications.

DEKS shear banded flexible couplings have been Watermark certified by ApprovalMark

International to AS/NZS 4327 and type test reports by NATA accredited test laboratories

have been submitted to demonstrate compliance to the performance requirements.

Deks Industries Pty Ltd is certified by British Standards Institute (BSI) to ISO 9001:2008.

DEKS shear banded couplings are considered as ‘fit for purpose’.

1.1 Recommendation

It is recommended that WSAA members, subject to any specific requirements of the member,

accept or authorise the DEKS shear banded flexible couplings, as detailed in this report, for

low pressure sewerage applications.

2 THE APPLICANT

(as provided by Deks)

Deks was established in Australia by Mr. George Cupit in 1947 and remained a family

business until it became part of the Skellerup Group in 2003. Deks continues to service its

clients in over 28 countries, providing the construction and industrial markets with high

quality products.

In 1910, George Skellerup opened the first rubber goods store in New Zealand and

developed his Para Rubber Co into 52 stores. Skellerup Industries was listed as a public

company in 1947 and has since expanded to cover a wide variety of global operations.

Both companies have a long and successful history as manufacturers of rubber products .

In August 2005, Deks acquired Jenco Products Pty Ltd.

Jenco was a well-established Australian manufacturer producing above and belowground

plumbing products, including a comprehensive range of pipe connectors and cast iron

drainage systems.

The Jenco range provided complimentary products to those already offered by Deks. The

acquisition is part of a long-term plan to broaden the range of market leading products for

the plumbing and building sector.

A national distribution network, located in each state, provides a distribution facility for a

range of couplings and cast iron surface fittings to water utilities and installation contractors

Australia wide.


COPYRIGHT

2.1 THE MANUFACTURER

The couplings included in this Appraisal are assembled in Vietnam, where the rubber

components are manufactured. The stainless steel components are sourced from China.

Deks has requested that the names and locations of the manufacturing plants remain

commercial-in-confidence. Copies of the relevant and current quality management

certifications for the suppliers have been submitted to meet the requirements of this

Appraisal.

3 THE PRODUCT

DEKS shear banded flexible couplings are designed for joining or repairing pipes of various

material with the same or similar nominal internal diameters in low pressure sewerage or

drainage pipeline systems.

Where the outside diameter of the pipes to be joined is greater than 16 mm an appropriate

adapter bush is utilised to facilitate leak proof jointing. DEKS product literature provides

details of specific applications where adapter bushes are required. See Appendix A.

The incorporation of a Grade 316 Stainless Steel metal shear band on the flexible coupling

counters the effect of soil or other superimposed load, to ensure rigidity and integrity of the

joint.

Each coupling has a designed compatible pipe OD range and is suitable for connection to a

wide range of pipe materials including PVC, PE, Vitrified Clay, Asbestos Cement, concrete,

galvanised iron, and cast or ductile iron.

The couplings are not suitable for use with drinking water.

FIGURE 1 SHEAR BANDED FLEXIBLE COUPLING

The available coupling range includes DN 100, DN 150, DN 200, DN 225 and DN 250 as

detailed in Table 1. The compatible pipe outside diameters for each coupling is also given in

Table 1.
