• $95 million wastewater treatment plant now complete
  • Plant to cater for growth in Perth's south-west metropolitan corridor

Water Minister Mia Davies today announced the completion of the East Rockingham wastewater treatment plant, which was built on time and $13 million under budget.

"The $95 million plant contains the latest wastewater and odour treatment technology, to minimise any odours produced through the treatment process," Ms Davies said.

"The facility is an important investment and is expected to cater for the rapidly growing population of Perth's south-west metropolitan corridor.

"Up to 20 million litres of wastewater from households and businesses bounded by Naval Base to the north, Singleton to the south and Byford to the east will be treated at the plant each day.

"By 2070, it is expected the plant will be expanded to treat up to 160 million litres of wastewater a day, which will service about 800,000 people and make it one of the largest wastewater treatment plants in Perth."

The Minister thanked the local community for their input throughout the design and construction of the facility.

"The community played an important role in development to ensure this essential infrastructure has minimal impact to the surrounding community," she said.

Construction of the plant began in 2014, with final testing completed this month.
