In Lower Hutt, Wellington Water manages our drinking water, wastewater, and stormwater.
Wastewater (or sewage) is dirty water from homes and businesses that goes to a wastewater treatment plant for treatment. It's a mixture of water and human waste. Sewers (or wastewater pipes) are the pipes in the street that transport the wastewater to the treatment plant.
Stormwater is rain which has run off hard surfaces such as roofs, roads and carparks. It isn't treated and the water ends up in streams and harbours.
Check out our tips on how to save water around the home.
Looking after our wastewater
Our wastewater network is only designed for pee, poo and toilet paper. Don’t use it to dispose of sanitary items, motor oil, fuels, solvents, and antibiotics. Find out more about looking after your wastewater.
Avoid insinkerators in the kitchen. These chop up solid food to make it go down the sink pipe easier.
Looking after our stormwater
Remember, the stormwater drain is only for rain.
What goes down our stormwater drains ends up in our streams and in the sea. It's important that we all work to protect our river and streams.

You can help. When washing a car, the wastewater running off it contains metals, detergents and oils. Don't let your wastewater go straight into a stormwater drain. Park your car on the lawn instead, and let the grass filter the water - or take your car to a commercial car wash.
