Monbulk Sewerage Project

As part of the Community Sewerage Program, Yarra Valley Water is planning a modern sewerage service for Monbulk.

In Monbulk, there are approximately 160 properties in the town centre that are connected to the Monbulk Sewage Treatment Plant. All other properties manage their wastewater via onsite treatment systems, such as septic tanks.

In the mid-2000s we began investigations for providing sewerage services to Monbulk. Options were developed and assessed - and shared with the community.

The Monbulk Sewerage Project will provide new sewerage services to properties unable to contain wastewater onsite. This service has two parts:

  • a sewerage pipeline located within road reserves that connects to the network of pump stations and treatment plants – and relies on gravity
  • an underground pressure pumping unit, located within private property, that connects to the sewerage pipeline within the road reserve.

This two-part sewerage system means we can provide an economical and environmentally friendly way of collecting, transporting and disposing of wastewater from households.

Did you know?

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

Project updates

  • July 2020

    To better manage the number of properties to be connected to this new sewerage system, we have split this project into four packages of work.

    The map shows each of these areas. 

    View Monbulk Package Boundary Map

    Package A – reticulation sewers throughout central/northern area of Monbulk

    We are working hard behind the scenes preparing for construction work to begin in your area soon.  

    Our delivery partners will be adhering to government Stage 4 restrictions for small-scale construction sites, operating under their business’ COVID Safe Plan, as well as a site-specific High Risk COVID Safe Plan to make sure our employees, contractors and the community remain safe.  

    Package B – reticulation sewers throughout eastern area of Monbulk

    We are in the design stage for this package of work. We expect our design to be completed in the coming months and tendering to start in early 2021.

    Package C – reticulation sewers throughout the southern and western area of Monbulk

    This package of work is in the design stage. We expect the design to be completed in the coming months.

    Package D – sewerage pump station in Baynes Park and rising main

    We are currently assessing the tender for this project and anticipate awarding the contract in the coming weeks. Construction is anticipated to commence approximately two months after award of the contract.

    Once we award each of the packages our delivery partner, Pressure Sewer Services Australia (PSSA) will contact homeowners to offer design appointments for your onsite pressure sewer unit.

  • August 2019

    Everyone in Monbulk Community Sewerage Area can connect to the new sewerage system

    Yarra Valley Water will be constructing a piped sewerage system for Monbulk Community Sewerage Area. 

    Sewerage pipes in the streets will connect to your property and the sewage will be taken away to a sewage treatment plant.

    A piped sewerage system will provide a healthier and more efficient sewerage solution for Monbulk now and in the future. 

    In October 2017 and February 2018, we informed some customers that they would not be able to connect to the new system. We received feedback from your community that this was unfair. 

    We have listened to this feedback and now all properties will be able to connect.

    What will happen next?

    Our pressure sewer contractor, Pressure Sewer Services Australia Pty Ltd (PSSA) have completed initial site investigations on your property. 

    Next year, PSSA will be inviting you to book a design appointment, to discuss details about the pressure sewer unit to be installed on your property and the best location for it. 

    Our designers Jacobs Australia Pty Ltd are continuing their site investigations throughout Monbulk that will help us complete the final design.  

    Connecting to the new system is better for you and the community

    Connecting to a piped sewerage system means you will never have to think about your sewerage again. You will not need to maintain or replace a septic tank when it gets old.

    The project will benefit the Monbulk community by providing a modern, sewerage system designed to meet the needs of the community now and in the future. 

    When septic tanks are unsuitable for a property, fail, get old or are not maintained properly they can leak waste to the local environment causing a health risk, unpleasant smells, boggy areas and pollution of local waterways.

    The more properties that connect to the new system, the better for the whole community.

    We will be at the Monbulk Produce Market if you would like to see us in person to talk about the project. Details for the market are as follows:

    Date: Saturday, 9 November 2019
    Time: 9:00am to 1:00pm
    Location: 73 Main Road, Monbulk

  • December 2018

    What is happening now

    We are designing the sewerage infrastructure for Monbulk Sewerage Project.

    Representatives from our design consultant, Jacobs, are in your area to undertake site investigations. This involves them walking or driving along local streets, and occasionally in public land such as parks and reserves to understand the area’s ground levels and the location of existing services (such as powerlines, underground cables), which will help us in completing the design of the sewerage system for the Monbulk area.


    Project Timeline

    The current estimate is to commence construction mid-2020 and have the project completed by end of 2021. Please note the note the timing of the project is dependent on a range of approvals, including planning permits, and is subject to change.

    We will keep you updated about changes in the timeline and send you more information as we get closer to construction.

  • October 2017

    Between 10 July and 4 August 2017, we ran an online forum where you could have your say about which sewerage service you think is best for Monbulk. 

    People were asked to watch the 5 minute video about the two possible sewerage options for Monbulk, and post their opinion on Yarra Valley Water’s preferred sewerage option. 

    In total, we had 102 participants. The comments we received on the forum have been reviewed, and helped to inform our decision about how to provide Monbulk with a sewerage service. 

    In addition to the online forum comments, we held an information session at the Monbulk Living and Learning Centre on 25 July 2017, where people in the community came along to talk to the project team about the proposed sewerage servicing approach for the area. 

    The session was an informal drop-in session, and attendance was not mandatory. There was no formal presentation. About 60 people attended, asking great questions of the project team about the project. 

    We also set up a pop-up stand in Main Road, Monbulk  on Saturday 29 July 2017. 

    Thank you for your input and attendance as part of our community consultation between 10 July and 4 August 2017.

    Proceeding with the pressure sewer option

    Our proposed servicing solution for Monbulk that we presented to the community was a pressure sewer option. About half of the people who provided feedback specifically showed their support for the pressure sewer option, with only about one per cent showing support for a decentralised servicing option. The rest did not provide a preference.

    A summary of what people said is shown in the table below:

    Consultation type Total number of registered participants Pressure sewer option preferred Decentralised servicing option preferred
    'Have Your Say' online forum 31 26 -
    Community information session & pop-up information stand conversations 47 19 1
    Phone calls 15 2 -
    Emails 9 4 -
    Total 102 51 1

    With the pressure sewer option being most preferred we have made the decision to proceed with a pressure sewer network to service the Monbulk area.

    Next steps

    Letters were sent this month, advising residents and property owners in Monbulk of the outcome of the Land Capability Assessment (LCA) for their property, and if their property is being serviced as part of the Community Sewerage Program.

    We will now commence the functional design of the sewer network, which will help determine the best locations for the sewer pipes.

    Once we have completed the functional design of the sewer network, we willhold another information session where people can talk to the project team and find out more about where the pipes will be located, as well as how we determined which properties would be provided with a service.

    We will write to you with further information on the session in the coming months.

    Project timeline

    Construction of the sewer network is currently estimated to commence in early 2019, with the area being ready for properties to connect by mid-2021. Please note the timing of the project is dependent on a range of approvals, including planning permits, and is subject to change. We will keep people in the community updated about any changes to the timeline.

    How we assess properties

    For more information about the Land Capability Assessment, and what if means if a property will (or won't) be provided with a sewerage service as part of this program, please refer to the fact sheet.
