Tiwi sewerage pump station renewal

Power and Water’s sewerage pump station renewal program ensures that critical infrastructure is regularly assessed and maintained, and continues to operate safely and without impact to customers, stakeholders and the environment.

The Tiwi Sewerage Pump Station is the first of the facilities identified for renewal to maintain delivery of safe and reliable water and sewerage services to customers including the Darwin Hospital Precinct (Royal Darwin Hospital and Darwin Private Hospital), Tiwi and parts of Brinkin.

The new Tiwi Sewerage Pump Station will significantly prolonging the life of the asset (expected 50 years), reduce the risk of failure and overflows and minimise potential safety and environmental incidents and compliance breaches.

The project required approximately 15 specialised subcontractors, and during peak construction periods there were close to 30 people working onsite to deliver the project.

Using cutting-edge laser scan technology for precise infrastructure assessment, and the application of advanced polyvinyl chloride continuous pressure laminate liner materials to enhance the wet wall, the refurbishment has extended the projected asset lifespan by 50 years and streamlines our ongoing maintenance processes.

Power and Water Chief Executive Officer, Djuna Pollard, recently visited the project site to see firsthand the advanced technologies and innovative asset replacement strategies.

“I am really impressed with the safety and design features of the new Tiwi Sewerage Pump Station. Readings can be taken remotely from Ludmilla and air-conditioning has been installed in the switch room, providing a better working environment for our people.

“Congratulations to our Water Services Infrastructure Delivery Project Manager, Phillip Lo Castro, and the project team for their dedication and efficient project management to deliver the works on time, within budget and without any incidents,” Ms Djuna Pollard said.
