Our services

We supply water, wastewater, recycled water and some stormwater services to over 4.6 million people in Sydney, the Illawarra and the Blue Mountains.

Our Operating Licence sets out standards and requirements we must meet as a water utility. The licence also includes our Customer Contract.

Every day, we supply about 1.4 billion litres of water to our customers.

We source water from a network of dams managed by the Sydney Catchment Authority.

Most of our water supply comes from Warragamba Dam.

When dam levels fall below 70%, we can also source water from Sydney Desalination Plant.

Dam water is treated at one of nine water filtration plants. We then supply it to you through a network of:

  • over 21,000 kilometres of water pipes
  • 251 reservoirs
  • 164 pumping stations.
Water recycling reduces demand on water supplies. This leaves more water in our dams for drinking. It also reduces the amount of wastewater we need to treat.

Each day, we recycle about 125 million litres of water.

Our water recycling schemes make a significant contribution to the NSW Government's recycling target.

The target is to produce 70 billion litres of recycled water a year in Sydney by 2015.

We collect and treat about 1.3 billion litres of wastewater each day. This is done through a network of:

  • 24,000 kilometres of wastewater pipes
  • 680 pumping stations
  • 14 water recycling plants
  • 16 treatment plants.

After collecting and treating wastewater, we re-use it or release it into rivers or the ocean.

Inland plants treat wastewater to a high level so it can be released into rivers.

Three of our treatment plants are wet weather plants - Fairfield, Bellambi and Port Kembla. We only use these plants during major storms.

The biosolids we produce and capture in the treatment process are used in agriculture, composting or land rehabilitation.

Stormwater is rainwater that runs from roofs, roads and parks into stormwater drains. It then runs to creeks, the harbour and the ocean.

We provide stormwater services to about 525,000 properties through 442 kilometres of stormwater channels and pipes. These are mainly in south and south-west Sydney.

We also manage flood-prone areas and trunk drainage at Rouse Hill.

In other parts of Sydney, the Blue Mountains and the Illawarra, we work with local councils and agencies to manage the stormwater system.

Stormwater re-use projects contribute to the NSW Government's recycling target. The target is to produce 70 billion litres of recycled water a year by 2015.
