Increasing Merredin's Stormwater Holding Capacity and Minimising Evaporation Water Losses

Merredin, WA

Total funding: Total project cost of $821,358, with funding of $410,679 from the Australian Government under the National Water Security Plan for Cities and Towns (NWSPCT) and the remaining funding provided by the Shire of Merredin, and the WA Government Royalties for Regions scheme.

About the project

The Shire of Merredin will construct an additional lined earth dam to allow an increase in the amount of stormwater to be stored and used in the local community. An evaporation abatement mechanism will also be installed to minimise the increasingly significant water losses through evaporation.

Project benefits

This project will:

  • reduce potable water use by an estimated 25 million litres each year
  • maintain the town ovals and associated garden space green all year round
  • prevent stormwater being lost to the salt lakes further contributing to the ground water recharge compounding salinity effects and soil loss due to erosion, and
  • maintain the biodiversity attributes of the dam through the evaporation covers.

Progress

The project commenced on 6 May 2011 and is scheduled for completion by 30 June 2012.
