Products and standards

This webpage is dedicated to Barwon Water's product, material and design standards.

The information is intended:

  • product suppliers and vendors
  • construction and engineering designers and contractors.

This page includes:

  • our product catalogues for non-pressure and pressure pipeline systems
  • references to our infrastructure standards
  • an application for authorisation of new products
  • standard drawings.


We  provide detail on products, materials and standards approved for use in our infrastructure projects.

Approved products and materials

Barwon Water has adopted the approved products catalogue developed by City West Water with some limitations and exceptions (see supplementary catalogues, below).

You can search for City West Water-approved products on the Melbourne Retail Water Agencies (MWRA) product portal.

Note, there are no supplementary catalogies for the following:

How to use the product catalogues

To check if a product is approved for use by Barwon Water:

  1. Search the MRWA product portal to check that the product is approved by City West Water
  2. Refer to the relevant supplementary catalogue for limitations (section 1) or exclusions (section 2). 



Approval of new products

Suppliers and vendors can apply to have new products approved by Barwon Water.

We will only consider new products that:

  • fulfil an infrastructure need, and
  • have received a positive appraisal from the Water Services Association of Australia (WSAA) or one of the Melbourne metropolitan water retailers (City West Water, Yarra Valley Water or South East Water).

We will only appraise new products that fulfill these criteria and we may conduct field trials. We may also elect to direct the application to WSAA for an appraisal.

To apply for a new product approval, please use the form below.
