Overview of WSAA

The Water Services Association of Australia (WSAA) is the peak industry body representing

the urban water industry. Our members provide water and sewerage services to over 20

million customers in Australia and New Zealand and many of Australia's largest industrial

and commercial enterprises.

Based around our vision of 'customer driven, enriching life', WSAA facilitates collaboration,

knowledge sharing, networking and cooperation within the urban water industry. We are

proud of the collegiate attitude of our 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 influencers,

to monitor emerging issues of importance to the urban water industry.

WSAA was formed in 1995 as a non-profit organisation to foster the exchange of information

between industry, government and the community, and to promote sustainable water

resource management.

The urban water industry is committed to anchoring its services to customers' values, and

to enrich communities where water services have broad economic, environmental and social

values. In line with this our 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.

7 LIFE EXPECTANCY OF DI PIPE

7.1 Linings

Cement mortar lining is considered to be the default internal protection system for potable

and recycled water applications.

Seal coating may be applied over cement mortar lining. The intended purpose of a seal

coating is to reduce the contact between the cement mortar lining and the contents of the

water main, thereby restricting lime leaching and consequent high pH levels when conveying

soft (i.e. low carbonate alkalinity) water, especially in small diameter pipelines where flow

rates are low and residence times are lengthy.

AS/NZS 2280 suggests that consideration should be given to the use of seal coatings where

the total alkalinity of the water being conveyed is less than 30 mg/L.

Many Australian water utilities specify seal coatings as mandatory for pipes up to and

including DN 300.

Calcium aluminate cement mortar linings are intended for aggressive water applications and

are typically used in gravity and pressure sewerage mediums with pH between 4 and 12. For

applications outside of this pH range consideration should be given to polymeric lining

systems. Calcium Aluminate Cement is not AS/NZS 4020 compliant and is therefore not

suitable for potable water applications.

WSA Technical Note 6 - Guidelines for the use of cement mortar linings in sewerage

applications provides details of operating limits for different cements used for the cement

mortar lining of DI and steel pipes for sewers. It reviews literature with regard to the use of

cement mortar lining for sewerage conveyance and in particular focuses on the prime water

chemistry constituents that need to be considered viz. sulphate(SO4), pH, and hydrogen

sulphide (H2S) (which can be transformed to sulphuric acid). A copy of WSA Technical Note

6 is available for download from the WSAA website.

Polyurethane linings may also be considered for aggressive medium applications.

7.2 Coatings

The majority of Australian Water Agencies have adopted a policy of specifying loose

polyethylene sleeving (LPS) for all ductile iron pipes as a corrosion protection measure,

unless specialised coatings such as polyurethane or polyethylene, for example, are

employed. Properly installed LPS provides a high degree of corrosion protection by creating

a passive uniform environment around the pipe and limiting oxygen exposure. LPS should

be installed in accordance with AS 3681 and only accredited pipe layers trained in the

application of sleeving should be utilised.

The need for LPS depends on the type of soil and the required service life of the pipeline.

Ductile iron pipes may be buried without extra external protection in soils that are not

aggressive. In soils that are aggressive, and where either the time or the cost of soil

assessment is prohibitive, LPS is the recommended solution.

The application of zinc coatings has not historically been utilised on ductile iron pipes in

Australia, although they have been used in Europe for more than 60 years. Zinc coatings are

now provided in Australia as a standard offering with 200 g/m2 thickness complete with a

finishing layer and are considered to enhance the external corrosion benefits of pipe in buried

applications. In some soil applications it is considered acceptable to install zinc coated pipes

without polyethylene sleeving.

Enhancements to zinc coatings are also available where 85/15 Zinc-Aluminium alloy, copper

enhanced Zinc-Aluminium alloy and rare earth element enhanced Zinc-Aluminium alloys are

offered with 400 g/m2 thickness complete with a finishing layer. It is reported that these

coatings provide improved corrosion protection over standard zinc coating and allows for

installation in a wider range of soils, without the need for sleeving.

EN 545 nominates that DI pipes with zinc coating of 200 g/m2 thickness and min 100m thick

finishing layer or enhanced zinc alloy coating with 400 g/m2 thickness and min 100m thick

finishing layer can be buried without sleeving except:

For Zinc coatings

- soils with a resistivity less than 1500 Ω cm when laid above the water table, or less than

2500 Ω cm when laid below the water table

- mixed soils i.e. comprising two or more soil natures

- soils with a pH below 6 and a high reserve of acidity

- soils containing refuse, cinders, slags or polluted by wastes or industrial effluents

- areas where there are stray currents

For Zinc-Aluminium or enhanced Zinc-Aluminium alloys

- acidic peaty soils

- soils containing refuse, cinders, slag or polluted by wastes or industrial effluents

- soils below the marine water table with a resistivity lower than 500 Ω cm,

- areas where there are stray currents

EN 545 also advises that evidence of the long-term performance of the above-mentioned

solution (e.g. tests and references) should be provided by the manufacturer .

It should be noted however that there has been no proven experience or data to support the

extrapolation of European experience to Australian conditions and environments. It is

considered imperative that testing be undertaken to ensure that the soil environment meets

any necessary pre-conditions.

Manufacturers should be consulted for life expectancy estimates.

Refer to Appendix D for the manufacturers life expectancy estimates for the DI pipe

considered in this Appraisal.

8 FITTING INSTRUCTIONS, TRAINING AND INSTALLATION

Installation methods for DI pipes are generally in accordance with AS/NZS 2566 Buried

flexible pipelines Part 2: ‘Installation’. The standard specifies the requirements for the

installation, field testing and commissioning of buried flexible pipelines with structural design

in accordance with AS/NZS 2566.1.

Viadux provides training, assessment and accreditation for pipelayers through its CENTURY

PLUS pipeline installation training course. It also provides technical support services, such

as water analysis, soil survey, hydraulic and mechanical calculations. Special and

appropriate training is available, upon request.

A comprehensive range of literature, including a Design Manual, Handling and Installation

Manual and various brochures are available from Viadux.

9 PRODUCT MARKING

Saint-Gobain PAM ductile iron pipes are branded with markings that clearly identify the

manufacturers mark, nominal size, classification, traceability (using batch number), codes

for manufacturing facility locations and manufacturing standard. Additional markings have

been added to identify pipe class, internal linings and external coatings.

Pipes have the following markings conforming to AS/NZS 2280:

(a) Name of manufacturer – PAM

(b) Nominal size – DN xxx (100-750)

(c) Classification – PN20, PN35, FC

(d) Australian Standard – AS/NZS 2280

(e) Colour coding for sockets - PN20-Blue, PN35-Red, FLCL-Blue

In addition, batch numbers for traceability and codes for manufacturing location are included.

The type of pipe is also marked e.g. TYTONXCEL, TYTONXTREME

TYTONXTREME ductile iron pipes are marked ‘Not suitable for drinking water’ continuously

along the length with legible lettering of minimum 20 mm height.

10 PACKAGING AND TRANSPORTATION

All pipes will be packed in fully sealed shipping containers and/or carefully stacked in bulk

vessels at the place of manufacture, transported to shipping port facilities, then shipped to

Sydney where the containers are off loaded and transported to Viadux storage facilities

located in Sydney, Melbourne and Brisbane for national distribution. Alternately the

containers can be shipped to the nearest port to a project.

Pipes are protected in the shipping containers by bundling with vertical and horizontal timber

spacers to ensure the coatings are not damaged. Saint-Gobain PAM ships approximately

40,000 km of pipe products to world markets each year. Saint-Gobain PAM has a reputation

for the highest quality and ensures products arrive to the customer in the best condition.

Viadux has distribution centres that are spread strategically across the country to form a

comprehensive nationwide warehousing and distribution network.

Competition and Consumer Act 2010 (Cth), which covers manufacture to the relevant

standard, and details of Viadux’s warranty is included in their terms and conditions of sale.

12 WATER AGENCY EXPERIENCE WITH THE PRODUCT OR FIELD TESTING

REPORT

Ductile Iron pipe has been in common use for many years with most Australian water

agencies having utilised the product. Additional field testing is not proposed for this

Appraisal.

13 DISCUSSION

A complete range of compatible ductile iron fittings, mechanical couplings and repair clamps

are available from Viadux.

TYTONXCEL and Flange Class ductile iron pipes can be direct tapped but may require either

a tapping band, flanged off take clamp or pre-tapped connector, depending on the pressure

class, diameter and off-take of the branch required. In some jurisdictions, providing service

connections from a DI pipe requires mandatory use of a tapping band, flanged off take or a

pre-tap connector.

Specialist contractors should be used when tapping mains under pressure.


COPYRIGHT

NOTE: The Water Agency’s requirements for “dry” or “under-pressure” tapping should be

outlined in the Specification.

Electrical insulation of copper water service pipes and fire services to ductile iron is

recommended to prevent galvanic corrosion and for safety reasons.

Under pressure cut-in applications performed in accordance with WSA 03:2011 Appendix C

– Under Pressure Cut-In-Connections to Pressure Pipe ≥ DN80 has proven to be

satisfactory. Mechanical flanged off-take clamps complying AS 4181:2013 Repair and off-

take clamps for water industry purposes is recommended.
