  • ATP Ultra Filtration/Reverse Osmosis Plant (Electricity) (18%)
  • Head Office (Gas and Electricity)(14.2%)
  • Pump Stations Electricity (16.6%)
  • Other (9.5%)

Their Energy Strategic Plan considers current and future energy requirements and follows the Environment Protection Authority’s Carbon Management Hierarchy

The specific Energy Management Actions and Programs undertaken by City West Water are;

  • Renewable energy incorporated as a component of Integrated Water Management initiative
  • Continue to assist customers with energy efficiency through relevant partnerships
  • Continuously review efficiency opportunities (using the cost of carbon abatement tool)
  • Improve management of energy through active controls by installing a new SCADA system
  • Improve pumping efficiency through real time water demand forecasting (MABAL)
  • Move to an office building that will halve their energy use
