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
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
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.
