Water quality testing

We test and maintain water quality from the catchment, at treatment plants, in storage basins and tanks, throughout the pipe network, to your tap.

We employ an independent laboratory to undertake comprehensive monitoring. The laboratory is accredited by the National Association of Testing Authorities (NATA).

We monitor:

  • water sources such as rivers, creeks, reservoirs and aquifers
  • treated water at our treatment plants
