Kallista Sewerage Project Stage 1

Yarra Valley Water is in the planning stage of this project to provide sewerage services to properties in Kallista, The Patch and Menzies Creek.

Project details

As part of Yarra Valley Water’s Community Sewerage Program, the Kallista Sewerage Project will provide a new sewerage service to properties in Kallista, The Patch and Menzies Creek that can’t contain their own wastewater on-site.

Providing a new sewerage service to the area will eventually involve constructing new sewer pipes in local streets, and then having properties connect to those newly constructed pipes.

Some septic tanks are polluting backyards and local creeks

Properties in Kallista, The Patch and Menzies Creek aren’t currently connected to Melbourne’s network of sewerage pipes. Instead, the sewage from their flushed toilets, and from their sinks and household drains, flows into a septic tank located underground on their property.

Even when septic tanks are regularly maintained, some properties won’t be able to keep all of their septic tank flows within their own land boundary. Unfortunately for these properties, this can result in diluted sewage creating boggy patches in the backyard, or flowing into street gutters or neighbouring properties’ yards. Eventually, this pollution finds its way into stormwater drains and nearby creeks. People, household pets and local wildlife can get sick from contact with boggy yards and polluted waterways.

Providing sewerage services for properties that are at risk of polluting

Yarra Valley Water is spending millions of dollars to build new sewerage pipes in your area by 2019.

Properties that can’t contain their own wastewater on-site will be provided with a new sewerage service. While most of the cost of connecting to the new sewer would be paid for by Yarra Valley Water, property owners would also need to pay for a few things.

Project updates

  • July 2019


    Construction on the lower section of the Olinda-Menzies Creek transfer pipeline commenced in February 2019 and is on schedule to be completed by November 2019.

    This infrastructure will form the back bone of the network and enable the ultimate completion of Kallista Sewerage Project Stage 1 and 2 which will service over 1000 properties in Kallista, The Patch, Menzies Creek and Sherbrooke.

    Properties in Package 1 and Package 3 investigation areas (as shown on the above map) are scheduled to be declared ready for connection by mid 2020. Construction commenced on Package 1 in February 2019 and construction on Package 3 is due to commence late in 2019.


  • October 2018

    We are currently finalising the design of the pressure sewer system and over October our pressure sewer contractor, PSSA, will be contacting property owners about the design and installation of the system on each property.

    Project time frame

    We anticipate that construction of the sewer will commence in early 2019 and be completed by late 2019. Prior to completion of the sewer we’ll be in touch with property owners again with information about connecting to the new sewer system.

  • March 2018

    Community information session

    Property owners and tenants have been sent letters inviting them to attend a community information session on Tuesday 20 March. The informal drop-in session will not feature a presentation, and you can turn up at anytime and stay as long as you like.

    Tuesday 20 March 2018
    6.30pm to 8.30pm
    The Patch Primary School Hall
    53 Kallista-Emerald Road, The Patch

    Yarra Valley Water's project team will be available to answer your questions about the way sewerage services will be provided to the area, and in which streets new sewer pipes are likely to be built.

    Pressure sewer service

    The new sewerage service to be built in the area is known as a 'pressure sewer' - this means Yarra Valley Water will be building a network of small-diameter sewer pipes under local streets. 

    Each property that connects into the pressure sewer network will have a tank located underground on their land, and that tank will contain a pump that pumps the household's collected sewage flows from the tank into the sewerage pipe network out in the street. Each property will also have a pump controller box installed above-ground (close to the house), which allows Yarra Valley Water to remotely monitor your property's sewerage service in the unlikely event of a fault.

Did you know?

Poorly performing septic systems can be a nuisance for you and your neighbours by creating unpleasant odour and soggy backyards.

Understanding what is important to the community

In April 2016, we asked people living in Kallista, The Patch and Menzies Creek to tell us what they value most about their community.

By completing a short survey, residents told us the following:

  • Nearly all respondents said that they most value the natural environment, animals and tranquillity in the area
  • A quarter of all respondents have observed sewage runoff from septic tanks. Of those observations, most (63%) were by people living in Kallista, followed by The Patch (26%), and the fewest observations were in Menzies Creek (11%).
  • Overall, 45% of respondents would prefer a different sewerage service to their existing septic tank, 43% would prefer to keep their existing septic tank, and 12% don’t have a preference.
  • The main reason stated for wanting a different sewerage service was to protect the environment from pollution, whereas the mains reason for wanting to keep existing septic tanks was the perceived cost associated with getting a new service.
