Work has commenced to alleviate leachate seepage from landfill on Malabar Headland and to direct stormwater drainage away from the children’s rock pools at South Maroubra beach.

The civil works, which are funded by the Commonwealth Government, formally commenced Friday 9 February and the current stage should be completed by June 30 2013.

Friends of Malabar Headland member Claire Bettington has prepared a series of diagrams that illustrate, as the Friends understand it, the complex drainage patterns and the interaction of leachate from the landfill beneath the rifle range, stormwater from Malabar Headland and Randwick City Council stormwater from South Maroubra.

The diagrams show the various flows to South Maroubra beach at present, which impact the children’s rock pools in particular. They illustrate how the Commonwealth’s program of works will address the contamination and hygiene problems these uncontrolled flows have caused up to the present.
