Water Supply

Rio Tinto is the service provider for the Weipa Township. Weipa Town Authority (WTA) manages and maintains the water distribution and infrastructure in conjunction with Rio Tinto.

WTA and Rio Tinto responsibilities include to:

  • Maintain water supply infrastructure and assets

  • Provide information for residents and businesses in relation to water leaks, meters, usage and water quality.

    Currently there are 2 water supply schemes within Weipa – Rocky Point and Evans Landing.

    Rocky Point Supply Scheme

    Rocky Point Supply Scheme is supplied water from a combination of 9 shallow aquifer bores, pumped to a 9 megalitre open holding dam. This bore water is drawn from the holding dam via high lift pumps and treated by the addition of chlorine and lime before discharging into an elevated water reservoir. This steel reservoir holds approximately 0.9 megalitres of treated water for gravity distribution via the water network to parks, houses and commercial properties within Rocky Point, Golf Links, Trunding and Nanum. A booster pump cuts in when necessary to maintain supply and pressure within Nanum.

    Evans Landing Supply Scheme

    Evans Landing Supply Scheme is supplied water from the RTA Weipa shallow aquifer borefield. It is treated for lime and pumped to 2 x 0.5 megalitre storage tanks for delivery and distribution throughout Evans Landing.

Water quality

WTA adds lime and chlorine to the town’s water supply to improve the water quality. In addition, we undertake regular testing to ensure that the quality of the water supplied to residents meets guidelines for drinking water.

Water samples are taken weekly and tested for bacteria including E-coli, Heterotrophic Plate Count, Total Coliforms and pH levels. In addition, annual samples are taken and tested for minerals and hardness. The data from recent test results can be found below.
