The Tea Gardens WTP is primarily designed to improve the quality of water that is delivered to the Tea Gardens and Hawks Nest area. The new plant will use pressure membrane technology and provide for a capacity of 12 million litres a day. The Tea Gardens and Hawks Nest area currently draws its water supply from a borefield to the north west of Tea Gardens. A total of 10 bores tap the aquifer 22 metres below the surface. The groundwater supply has always presented the client with treatment problems, due to high acidity and iron levels. This is not a health concern, however it can cause discolouration that can stain laundry. The new treatment plant will use primary and secondary pressure membranes and a complex control system, which will ensure a constant supply of high quality treated water. As well as the new membranes the project to improve the water supply for Tea Gardens and Hawks Nest will include the construction of new aerators, balance tanks, pumping station and chlorination facilities to ensure disinfection.
