SewerFix

SewerFix is an extensive program to improve our sewerage system, reduce the number of sewage overflows reaching waterways and protect public health.

Running until 2010, SewerFix will cater for population growth and will impact on the whole sewerage system - pipes, storage facilities, sewage pumping stations, ventilation shafts and designed overflow structures.

The program of activities is developed from a whole-of-system analysis. This analysis has highlighted system limitations, the associated causes and identifies risks and priorities.

The work is being carried out in three areas:

Achievements

  • Chatswood sewerage amplification project completed in 2003 set a world record for the longest (1806 metres) continuous grade horizontal directional drill.

  • Works in the Blue Mountains since 2003 has reduced the risk of wet weather overflows to our National Parks.

  • Since 2003, the number of overflows from sewage pumping stations has been reduced from 50 overflows per year in dry weather to two or three per year.

  • 250 sewage pumping stations have been upgraded.

  • Telemetry systems have been installed in all sewage pumping stations.

  • Response times to attend to sewage pumping station failures have fallen from 6.5 hours to 4 hours.

  • SewerFix project team for upgrading sewage pumping stations won the Gold Award in the NSW Premier's Public Sector Awards 2004.
