Hunter Water is a State-owned Corporation providing water and wastewater services for over half a million people in the lower Hunter region. There are 220,600 properties connected to the water network and 208,660 to the wastewater network. Our total assets are valued at approximately 2.2 billion dollars.

Our area of operation covers 5,366km2 with a population of 527,557 in the local government areas of Cessnock, Lake Macquarie, Maitland, Newcastle, Port Stephens, Dungog and small parts of Singleton.

Bulk water is supplied to small parts of the Great Lakes area. We have capacity to supply up to 35 megalitres of water per day to the Central Coast. We also provide some stormwater services to the lower Hunter, with 100km of stormwater channels in Cessnock, Newcastle and Lake Macquarie.

We deliver an average 205 megalitres (one megalitre equals 1 million litres) of water per day.Our raw water sources are: Grahamstown Dam (190,000 megalitre capacity), Chichester Dam (21,500 megalitres), Tomago Sandbeds (60,000 megalitres) and Anna Bay Sandbeds (16,000 megalitres).

We collect, treat and then deliver drinking water to our customers and then transport, treat and dispose of the region’s wastewater.

Our water consistently meets the most recent guidelines for drinking water set by the National Health and Medical Research Council (NHRMC).

Wastewater is collected and treated to a very high standard and clear effluent is discharged to waterways or reused where it is economically and environmentally beneficial.
