Power and Water has completed a renewal of the Tiwi Sewerage Pump Station as part of its Sewerage Pump Station Renewal Project. 

The project works included refurbishment of the pump station building, electrical upgrades and fabrication and installation of new pipework infrastructure.

The next stage of the project is the renewal of the Mindil Beach Sewerage Pump Station, with work due to commence in June 2024.

Tiwi Sewerage Pump Station was the first facility identified for renewal by Power and Water 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.

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

The updated Tiwi pump station is expected to prolong asset life by 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, with close to 30 people working onsite to deliver the project during peak construction periods.

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 extended the projected asset lifespan by 50 years and helped streamlined 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 Pollard said.
