Great Southern

Steady population growth in coastal towns and the impact of climate change are driving our plans for the Great Southern.

The region has a number of local independent town water supply schemes. There are also 2 integrated networks – the Lower Great Southern Towns Water Supply Scheme (LGSTWSS) and the Great Southern Towns Water Supply Scheme (GSTWSS).

Summaries of our regional water and wastewater schemes are currently being updated and will be available shortly. 

Our plans to secure drinking water supplies

In the Great Southern region, we are undertaking several projects to secure drinking water supplies for the mid- to long-term, including:

  • investigating ways to augment Harris Dam – the main source that supplies the Great Southern Towns Water Supply Scheme
  • developing new groundwater and surface water sources in the region
  • undertaking feasibility studies for a future desalinated water source for the LGSTWSS
  • implementing alternate non-drinking water supplies for local community use, such as irrigating public open spaces.

Our wastewater services

We operate and maintain 20 wastewater schemes in the region.

To cater for community development and growth, there have been significant upgrades to the wastewater treatment plants at Denmark, Narrogin and Albany.

Commitment to increasing water efficiency and water recycling

We recycle 91% of our wastewater flows for beneficial community re-use in Narrogin, Esperance and Katanning. In Albany, 2,000 million litres of treated wastewater are used on an Albany tree farm each year.

Denmark water supply upgrade

Denmark received less than average rainfall during 2014-15, which resulted in significantly lower levels in its drinking water dams. To maintain supply for the community, we have begun work on a number of initiatives that will provide water security in Denmark for both the short and long term. 

For details on this project see Denmark water supply upgrade.
