Wastewater

We maintain wastewater systems to provide the community with a safe and healthy environment through the appropriate treatment and discharge of wastewater.

Wastewater

This covers both domestic wastewater and trade waste.

Our reticulated wastewater system handles domestic sewage from kitchens, bathrooms, laundries and toilets. It also receives a smaller amount of liquid discharge from commercial and industrial premises, such as discharge from restaurants, takeaway outlets, food processors, metal finishers, service stations and chemical manufacturers.

Report a problem with your wastewater

If you have a pressure wastewater system you can report a problem with your pressure wastewater system.
