THE PROJECT

Managed aquifer recharge is being considered for water supply in the Myalup Irrigated Agricultural Precinct.  Allocation limits and salinity concerns at Myalup prohibit increased extraction from the Superficial Aquifer.

An option of increasing groundwater availability that is being assessed is to seasonally recharge the aquifer up to 26 GL/annum of water from various surface water sources.  A trial is planned involving infiltration of up to 1 GL/a from a nearby drain.

Rockwater was engaged by the Department of Primary Industries and Regional Development to perform Stage 1 and MAR risk assessments for the MAR scheme at Myalup.

The next step is to perform a small-scale trial using an infiltration basin.  Rockwater designed the MAR trial and continues to provide regulatory liaison.
