Reducing Water Loss in the Otway Water Supply System


On 21 September 2015, responsibility for water policy and resources was transferred to the Department of Agriculture and Water Resources - Administrative Arrangement Order made on 21 September 2015.

This website will be updated to reflect these changes.

Warrnambool, Victoria

Total funding: Total project cost of $1.276 million, with funding of $638,200 from the Australian Government under the National Water Security Plan for Cities and Towns and the remaining funding provided by Wannon Water.

About the project

Through this project Wannon Water will accurately measure the flows of water through the Otway Water Supply System to determine the areas of water loss with the view to planning and monitoring cost effective actions to reduce the losses in this distribution system. The key activities will be the installation of electromagnetic flow meters to measure flows through the distribution pipeline and storages. The connection of these meters with Supervisory Control And Data Acquisition (SCADA) will allow real time monitoring and measurement of water losses through leakage and evaporation.

Project benefits

This project will:

  • reduce potable water use by 730 million litres each year
  • achieve a better understanding and knowledge of the water supply system by undertaking an audit of the system and future monitoring of the data
  • identify and reduce water loss in the Otway distribution system - the largest system within the Corporation's operational area and provides water to 11 towns, and
  • ensure less stress is placed on the natural environment, especially aquifers.


The project commenced on 19 August 2010 and is scheduled for completion by 30 June 2012.
