Wastewater

The Christchurch City Council maintains wastewater systems to provide the community with a safe and healthy environment through the appropriate treatment and discharge of its wastewater. This covers both domestic wastewater and trade waste.

Wastewater

Our reticulated wastewater system handles domestic sewage from kitchen, bathroom, laundry 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.
