Located in the upper Derwent Valley approximately 90 kilometres north-west of Hobart, Wayatinah was established in 1953 to house Hydro-Electric Commission workers.

Built between 1953 and 1955, the current system draws water from Hydro’s Lake Liapootah and passes through a coarse filter and several disinfection processes before being distributed to approximately 77 TasWater customers. Wayatinah has been subject to a permanent Boil Water Alert (BWA) due to poor water quality for many years.

The solution

To provide quality, treated drinking water to Wayatinah’s residents, it was decided that a new water treatment plant (WTP) will be constructed at the town’s existing pump station site. Raw water from the Liapootah Power Station penstock will gravitate to the new WTP, and the treated water will be stored in a new service reservoir connected to the town’s existing water pipe system.

A re-chlorination station will also be constructed to ensure the chlorine residual is maintained (the supply adequately disinfected), ahead of distribution to TasWater’s customers. The existing service reservoir, pumping station and chlorine station will be taken out of service at the project’s completion in 2018.
