Margaret River Wastewater Treatment Plant


The new high tech Margaret River Wastewater Treatment Plant has been handed over to the Water Corporation by the contractors who designed and built it, IT Environmental (Australia) Pty Ltd, following 12 months of successful trial operation.

Under the contract, IT Environment was required to operate the plant for the first year to make sure it met requirements.

The fully automatic, state of the art plant is now under the supervision of the Water Corporation's Margaret River based Leading Water Industry Operative Mr Allan Miller.

The $10.8 million project included construction of the plant, a 2.8 km pipeline, a pumping station near the Margaret River bridge and a 400 megalitre (million litres) storage reservoir from which highly treated wastewater is pumped during summer to irrigate a 60-hectares pine plantation operated by CALM.

Water Corporation South West Regional Business Manager, Mr Chris Elliott, said all of the plant's output was being used to irrigate the plantation, which was an excellent outcome for the environment.

The Margaret River scheme was similar to wastewater treatment and reuse schemes operating at Manjimup, Kemerton, Bridgetown, Busselton and Dunsborough.

"The upgraded treatment system also allows further growth in the Margaret River area, and enabled the connection of 65 properties as a result of the town's latest Infill Sewerage project," said Mr Elliott.

Margaret River's previous wastewater treatment plant had a pond system that provided only secondary treatment that was less efficient at removing nutrients. The new plant has a tertiary system that produces clear and odourless treated wastewater which is highly suitable for recycling.

Mr Elliott said the new plant had been constructed away from residential areas to avoid odour problems.
