Kallista Sewerage Project
No more septic tanks, boggy yards, unpleasant odours and polluted waterways.
Building a new sewerage system is a complex job that takes time. You’ll see us in your neighbourhood for the next couple of years. During this time, we’ll do our best to minimise disruption to your daily lives.
We’ll let you know what’s happening where and when and do our best to keep you going about your business as usual.
The project has been designed and delivered in three stages:
- Stage 1: The Patch and part of Kallista
- Stage 2: Sherbrooke and Kallista, including the shops on Monbulk Road
- Stage 3: Kallista and a small part of The Patch

What should you do right now?
You don't need to do anything right now, except keep maintaining your current onsite wastewater (septic) system. We'll be in touch with property owners directly as we progress.
Why does this area need a piped sewerage system?
Septic tanks work by gradually releasing wastewater so that it is absorbed by the soil and plants on your property. If they are old and beyond their service life, fail or aren’t maintained properly they can create unpleasant smells and boggy areas. They can leak waste onto other properties or the wastewater can flow into local drains and waterways. Sometimes properties are too small to contain the waste; or the land might be steep, so the waste runs off before it is absorbed.
Also, many properties have split systems where toilet water is treated by the septic tank and wastewater from the kitchen, shower and laundry flows into the stormwater system. This waste is not treated and flows into our creeks, rivers and bay, polluting our waterways.
What are the costs?
There is no cost to you for the construction of the sewerage system or for providing a connection point from your property. If you wish to connect, property owners will be responsible for the connection costs to the sewer. Visit our costs of connection page for more information.

Project updates
March 2025
We’re experiencing a delay with part of the Kallista sewerage network. We have a dedicated team working on designing a necessary pump station in a challenging, heavily treed location. We’ll be selecting a contractor to build this in the coming months. We expect this work will take up to 2 years to finish.
We apologise for the delays and acknowledge this may be frustrating and inconvenient. Thank you for your patience as we work to implementing a solution as quickly as possible. We’ll keep you updated on our progress.
January 2023
We've had some unexpected challenges with the design and location of booster pump stations that are part of the Kallista project.
As a result there will be significant delays of up to 2 years for some customers in this project area. We've contacted customers affected by these delays directly.
We're sorry for the delays and acknowledge this may be frustrating and cause inconvenience.
We’re continuing to work as quickly as we can to find solutions and start construction of the pump stations. We’ll keep you up to date as we progress.
This fact sheet provides information about booster pump stations and why we need to install them on our sewerage network.
June 2022
Construction of Kallista Stages 1 and 2 has started. Work is being delivered by Melbourne Pipelines in Stage 1, and Interflow has recently started Stage 2.
For customers living in these areas, now is the time to book your pressure sewer consultation. A consultation with our specialists contractor, Pressure Sewer Services Australia (PSSA), is your opportunity to talk about your preferred location for the sewerage equipment to be installed on your property. We can also expalin how the system work, the installation process and answer any questions you may have.
The consultation takes about an hour. After we've finalised the design with you, the installation work can be scheduled.
We're finalising design of Stage 3 and we expect construction will commence in early 2023.

June 2020
Currently, we are in the planning stage of this project and are implementing a number of site investigations and studies. We expect to complete the detailed design in early 2021.
Recently, we completed a significant number of topographical and ecological surveys. We also undertook ground condition investigations at several locations. These geotechnical surveys provide soil and rock samples that enable us to identify potential construction impacts and determine the type of equipment needed for the construction of the sewerage pipeline. They were completed in public land only, such as in parks, reserves or along the side of the road.
These investigations and studies help us to ensure that our final design has minimal environmental impacts and community disruption when we start construction.
While our planning work is being completed, you will notice some minor construction activity in your local area. Works at each site will take less than one day, and once completed, any disturbed surfaces will be reinstated.
We don’t expect this work to disrupt your everyday activities. However, should we need to access your property, we will be in contact with you.
Thanks for your continued interest in out Kallista Stage 2 project and your patience as we progress our investigations and assessments.
August 2019
Letters were sent this month, advising residents and property owners within the project area about providing a connection point to the proposed piped pressure sewerage pipes to be built as part of the Community Sewerage Program.
We will be at the Kallista Community Market if you would like to see us in person to talk about the project. Details for the market are as follows:
Date: Saturday, 7 September 2019
Time: 9:00am to 1:00pm
Location: 2 Church Street, Kallista
April 2019
Detailed design for all packages of Kallista Sewerage Project Stage 2 will commence in April 2019.
Land Capability Assessments of all properties within the investigation area are almost complete and results will be known shortly.
