Greenvale Sewer Flow Monitoring Trial

Yarra Valley Water is conducting a trial in the Greenvale area, to tackle the problem of rainwater entering our sewer pipes.

Project background

We are responsible for making sure our sewer pipes are the proper size to transfer sewage flows from your home to sewage treatment plants.

Sometimes during heavy storms, rainwater can find its way into our sewer pipes, increasing the flow significantly. When flows become too big, there is a risk of sewage spilling into the environment.

Project details

We have engaged a contractor, Ventia, to install an Overflow Relief Cap (ORC) to the existing plumbing of 450 properties in the Greenvale and Roxburgh Park area.

The ORC is a small device that is fitted to the Overflow Relief Gully in people's backyards, and it seals against rainwater entering sewer pipes during heavy storms.

Owners and tenants of the 450 selected trial properties have already been notified of the upcoming installation of an ORC on their property.

The installation will take about 5-10 minutes and involves two representatives from Ventia entering the backyard and fitting the ORC. All installations should be complete by the end of June 2016.

Once all ORCs have been installed, Yarra Valley Water will monitor the flow levels in the sewer system during the next few heavy storm events, to see if the ORC device is sufficiently preventing rainwater from entering the sewer pipes.
