Warragamba Pipelines

Warragamba Pipelines

About the project

  • Warragamba Dam typically supplies the majority of Sydney’s water needs. There are two pipelines that exit the valve house that are the primary method of water release from the dam.
  • These pipelines are an integral component of the Warragamba water supply system.
  • The project is upgrading pipeline infrastructure to ensure the efficient and reliable delivery of water from Warragamba Dam to Prospect, Orchard Hills or Warragamba filtration plants.

Purpose

Warragamba Dam is located about 65 kilometres west of Sydney in a narrow gorge on the Warragamba River. Created by damming Warragamba River and flooding the Burragorang Valley, the storage lake is four times the size of Sydney Harbour and stores around 80 percent of Sydney's water.

The best quality water is selected and drawn through screens on three outlets in the upstream face of the dam. Water flows by gravity through a valve house into two pipelines that feed the raw water to Prospect water filtration plant and via off-takes to smaller filtration plants at Orchard Hills and Warragamba

Benefits

  • Improve reliability, operation and efficiency of the water supply from Warragamba Dam to Prospect, Orchard Hills and Warragamba filtration plants.
  • This project will create jobs locally and ensure the delivery of high quality water to customers

Operations during the upgrades

Warragamba Dam will continue to operate as normal.  There are no closures expected to any recreation areas during this work.  Customers will be notified of any planned interruptions to the water supply.
