Kallista Sewerage Project

We're currently constructing a new sewerage system for properties in Sherbrooke, Kallista and The Patch.

When we've finished, over 800 properties in the area will receive a connection point to the sewerage system, providing property owners with the option to flush and let us take care of their wastewater.

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

Project updates

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. 

Book your consultation today

We're finalising design of Stage 3 and we expect construction will commence in early 2023.

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.
