The Hartfield Park managed aquifer recharge (MAR) project in the Shire of Kalumunda involves recharging an aquifer under controlled conditions to store water for later abstraction for irrigation use. The scheme harvests approximately 30% of high flows (25–50kL/yr) from an existing urban drain, which is then filtered and stored in Leederville aquifer. Water is then available for extraction in the dry season to irrigate the nearby sport and recreation reserve. For further information, download the case study below.
