The other side of the ‘water network coin’ is drainage (storm water and waste water).

In urban areas, the pipes that collect rainwater from your roof and yard are connected to a network of underground pipes that transfer the rainwater to local streams or to the seashore. These pipes are the storm water system.

There is also a separate system of pipes that transfer waste water from your toilet, bathroom, kitchen, and laundry to a sewage treatment plant in Seaview, Petone. These pipes are the sewerage system. In areas without storm water systems, rainwater from roofs and driveways may drain into soak holes. In areas without sewerage systems, waste water is generally treated in a septic tank.
