Managing wastewater

Every day we deliver safe drinking water to your home through our drinking water network. Some of this water is used outside (watering your garden, washing your car etc.), but most of it is used by you inside your house:

  • In the bathroom: toilets, sinks (brushing your teeth, shaving, washing your hands and face) and showering / bathing
  • Kitchen: Sinks (washing dishes and preparing food) and using the dishwasher.
  • Laundry: Cleaning your clothes by using the washing machine and sink.

Once used, this water leaves your home as ‘wastewater’, through your plumbing and into the public wastewater network. This network is separate to our drinking water network and stormwater network to keep you and our environment healthy.

Our wastewater network carries a combination of residential and commercial (businesses) waste. Each day around 25 million litres of wastewater is removed from Upper Hutt through 223 kilometres of wastewater mains, manholes (access chambers), and 11 community pumping stations.

All wastewater is carried along the wastewater network and treated at one of our wastewater treatment plants, before being discharged out to sea, unlike the stormwater network which mostly flows straight out through streams and rivers before ending out at sea.
