Margaret River water supply and wastewater planning

back to current projects

Project goal:

Meet long-term water supply and wastewater needs.

Status:

In construction

Delivery Date:

2013

Current situation

To meet the long-term water supply, wastewater management and wastewater reuse needs of the Shire of Augusta-Margaret River we are making significant progress in the delivery of a suite of works that cater for projected growth in the region.

The $100-million suite of works involves upgrades to the Margaret River Regional Water Supply Scheme and the Margaret River wastewater management system. Our work will not only deliver climate resilience to all communities serviced by the water supply scheme, namely Margaret River, Cowaramup, Prevelly Beach and Gnarabup, but also ensure sustainable management of wastewater flows.

As the upgrades progress, we will continue to work with Margaret River residents, visitors and businesses to sustain water efficiency gains achieved to date.

Demand management is an increasingly vital aspect of our strategy to deliver climate resilience to water-efficient communities.  To support achievement of this objective, water efficiency and other compliance measures will continue to be complemented by educational initiatives and partnerships.

Communities in the Margaret River area are commended for embracing water conservation efforts to date.

Project details

The Margaret River Regional Water Supply Scheme upgrade involves a staged roll-out, which recently delivered:

  • a new groundwater water source that commenced augmentation of the Scheme’s primary surface water supply at Ten Mile Brook Dam in April 2012;
  • a pipeline to connect the groundwater source to Ten Mile Brook Dam; and
  • a new, 5-ML/day water treatment plant.

Stage 2 works commenced in April 2013 and involve:

  • a new 15 ML storage tank near the water treatment plant site;
  • transfer pumping and gravity supply mains and  upgrade of the existing drinking water pump station; and
  • a Pressure Reduction Valve.

Once the Stage 2 works have been delivered, we will decommission the two high-level tanks and associated facilities in Wilmott Avenue, near the centre of the Margaret River business district, and another on Station Road, near the Margaret River Football Oval. The 5-ML ground level tank adjacent to Ten Mile Brook Dam will also be decommissioned in due course.

Upgrades to Margaret River wastewater management facilities also involve a staged roll-out. Works to ensure treated wastewater reuse is sustained for the long-term include provision of a new irrigated woodlot and ancillary facilities to replace the existing woodlot, which has reached the end of its design life. These works will be completed in October 2013.

In December 2014, major works will commence to upgrade capacity at the Margaret River Wastewater Treatment Plant to 3 ML/day.
