WORK to expand the Woodman Point Wastewater Treatment Plant reached a milestone late last month, with the project’s first major concrete pour completed.

Sixty trucks spent eight hours pouring 360 cubic metres of concrete.

Water Corporation asset delivery manager Mark Leathersich said it will form the base of one of eight new tanks being built at the plant.

“The tanks are secondary sedimentation tanks and are a vital part of the wastewater treatment process,” he said.

“The tanks are where treated wastewater undergoes further settlement and clarification, which then produces final treated wastewater.”

The state’s largest wastewater treatment plant is undergoing a $196 million expansion to increase its capacity to 180 million litres a day.

The upgrades are being undertaken by Henderson firm Civmec and Black and Veatch Australia.

They include construction of a new grit removal facility, a new flow distribution channel, expansion of existing odour collection and treatment systems, new sedimentation tanks and conversion of the existing batch reactor to a permanent aeration facility.

When completed in late 2019, the plant will treat wastewater from 900,000 people south of the river.
