Glenfield Liverpool Effluent Diversion Scheme (GLEDS)

The Glenfield Liverpool Effluent Diversion Scheme (GLEDS) will enable Sydney Water to transfer treated wastewater from Glenfield and Liverpool Sewage Treatment Plants (STPs) along the Liverpool to Ashfield Pipeline for reuse by industrial customers. It will also reduce sewer flows and improve our ability to maintain and operate the North Georges River sub main. This will reduce overflows into the Georges River during periods of wet weather.

Sewage Treatment Plants

Sydney Water's sewage treatment plant (STP) improvement program has helped ensure there were no major breaches against our STP Environment Protection Licence in the past six years. During 2007-10 we have focused on maintaining STP performance and reliability and increasing capacity to service population growth. This work is currently underway at Winmalee and planned for Warriewood. The focus is now on minimising odour. Sydney Water is planning for this work to occur at Malabar, Cronulla and St Mary's.
