Managed Aquifer Recharge
CSIRO has been involved in a number of Managed aquifer recharge (MAR) projects and have a resource page for the technique. MAR is a method of adding a water source, such as recycled water, to aquifers (underground reservoirs) under controlled conditions. The main purpose of aquifer recharge is to store excess water for later use, while improving water quality by recharging the aquifer with high quality water.
The National Water Commission funded a project to develop guidelines for MAR. The national guidelines are now complete and give certainty to the risk assessments used in approving MAR projects and facilitating more widespread use of MAR schemes; preventing the failure of MAR projects; and lending confidence to investors and the public in future MAR schemes.
The Victorian EPA have developed Guidelines for MAR which facilitate safe and sustainable development and operation of MAR schemes; outline the relevant regulatory framework and make the approval process for MAR schemes more efficient and transparent and ensure efficient investment to achieve public health and environmental protection that is consistent with state requirements.

The Replacement Flows Project is part of the Western Sydney Recycled Water Initiative that is a component of the 2006 Metropolitan Water Plan. The project involves the construction and operation of an Advanced Water Treatment Plant (AWTP) and associated works and treats existing tertiary effluent from St Marys, Penrith and Quakers Hill sewage treatment plants (STPs) in north western Sydney at an AWTP located at St Marys. Up to 50 million litres per day (ML/day) of highly treated recycled water is produced and is substituted, as replacement flows, for water that is currently released from Warragamba Dam for extraction and river health purposes. A detailed monitoring program and environmental assessment is being undertaken
