Protecting Sydney’s drinking water supply

Published: 15 Jan 2020

The NSW Government is putting measures in place to protect Sydney's drinking water supply from ash and debris from the recent bushfires.

Water quality in key metropolitan supply storages, such as Warragamba and Tallowa, are being monitored by highly experienced scientists using sophisticated, real-time technology by WaterNSW.

Silt curtains and booms have been deployed at Warragamba Dam by WaterNSW to mitigate the inflow of ash to the system in the event of significant rainfall.

WaterNSW has an additional 1000m of silt curtains in case they are needed in either Nepean or Tallowa Dams.

Minister for Water, Property and Housing Melinda Pavey said the NSW Government’s priority is protecting Sydney’s drinking water supplies.

“We have worked closely with the RFS to ensure fire retardant chemicals used near Warragamba Dam are appropriate, and that exclusion zones were in place to avoid the use of retardants in close proximity to water where possible,” Mrs Pavey said.

“The NSW Government is also assisting local councils as the utility providers in areas affected by the recent fires by deploying resources to help with the management of their water supplies, including carting water where necessary.”
