Wastewater

​​​We operate wastewater collection networks and treatment plants and ensure the discharges are appropriately treated returned safely to the environment.

What is wastewater?

Each time you flush the toilet, pull the plug from a sink, or have a shower, the wastewater drains into a sewer drain on your property.
Wastewater includes organic matter such as human waste, food scraps, fats, oil and grease, and other debris such as sand, grit and plastic. Wastewater is also generated from commercial and industrial premises.
