our projectsPreparing for population growth

The five-year, $650 million Northern Sewerage Project, a joint project between Yarra Valley Water and Melbourne Water, will increase the capacity of the sewerage system to service growth in Melbourne’s northern suburbs.

Upon completion the new sewer will extend 12.5 km from Essendon to Reservoir in Melbourne's north. It will also improve water quality in local waterways, and ultimately the Yarra River, by virtually eliminating sewer overflows during wet weather.

In 2010 Yarra Valley Water successfully completed the final leg of its tunnelling works and the project is running ahead of schedule. We have constructed 4.5 kilometres of tunnel. The tunnel has now been fully lined and grouted. Using 27,514 cubic metres of grout, this is approximately equal to filling 11 Olympic size swimming pools!

In 2011 the focus is on tunnel shaft lining, construction of the Edgars Creek Intercepting Sewer and demobilisation works.
