Wastewater & Sewage

Wastewater is any water that has been negatively affected in quality by human activity. This can be derived from domestic, industrial, commercial or agricultural activities, surface runoff or stormwater and sewerage.

Domestic wastewater disposal is an important environmental issue on the Mornington Peninsula. There are more than 25,000 properties across the Peninsula without reticulated sewerage, and all of these properties rely on septic tank systems to dispose of their wastewater.

Septic Tank Maintenance and Care

It's important to ensure your septic tanks system is cleaned, repaired and well maintained. A poorly maintained septic system is a health risk to your family, friends, our waterways and the wider community.
