Water supply agreements

Water supply agreements

WaterNSW provides raw water to a range of customers across NSW.

For some of the customers arrangements by which water is provided is documented in water supply agreements.

The Water NSW Act 2014 requires that the supply agreement with Sydney Water must address:

  • water quality standards
  • continuity of water supply
  • costs the customer must pay for the water supply
  • how to resolve disputes and handle complaints.

Under our agreement with Sydney Water, WaterNSW provides raw water to Sydney Water's water filtration plants, and meets nominated water quality standards or criteria.

These criteria apply to the quality of water passing through the inlet to the various water treatment facilities and are based on historical raw water quality data and the water treatment facility's ability to treat the water.

How we manage raw water quality is also influenced by:
