Yarrambat Community Sewerage Program

We’re investigating the feasibility of a sewerage service for parts of Yarrambat that are currently reliant on septic systems. Over the coming months, our specialist contractors will survey and assess local conditions to inform our engineers. 

When we've finished,  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.

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.

This project will benefit the community by:

  • Improving the health of local waterways.
  • Protecting public health.
  • Reducing sewer odours that are currently noticeable in the area.
  • Providing a more liveable environment for locals and visitors to the area

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.

Investigation works in Yarrambat

We’re starting our investigation works, which will happen on and off until the end of 2025, mostly on weekdays from 7.30 am to 5.30 pm. You can expect extra vehicles, some noise, and temporary markings. Your water supply will not be affected. Traffic may be impacted by temporary lane closures, but we’ll keep you moving. Thank you for your understanding and patience.
