Palmerston trunk sewer upgrade to meet a growing community need26 November 2018
A newly-completed $10 million trunk sewer main in Palmerston East will provide capacity for future growth in the Northern Territory’s fastest growing urban area.
The Palmerston Eastern Trunk Sewer Duplication - Stage 2B project by the Power and Water Corporation was completed in November 2018 ahead of its December 2018 schedule.
Power and Water General Manager Water Services Steven Porter said the trunk sewer main was an important piece of infrastructure in facilitating future developments in the area north of the Stuart Highway.
“Palmerston East is one of the fastest-growing urban areas in the Northern Territory and we want to ensure we can continue to provide our services safely and reliably to the community,” Mr Porter said.
“The new sewer trunk main became operational in early November and is now servicing the suburbs of Zuccoli, Rosebery and Johnston.”
Construction on the sewer main began in May 2017.
The majority of the 1.5 kilometre trunk sewer main was constructed using microtunnel boring machinery (MTBM) with state-of-the-art laser guidance system technology.
The project deployed tunnelling and trenching under and through three Palmerston suburbs, running from Bonson Terrace in Moulden, through park and recreation grounds in Woodroffe to Antonino Drive in Rosebery.
In an exciting first for the Northern Territory, the project also saw glass-reinforced plastic (GRP) manholes designed, engineered and installed.
The new manholes are corrosion-resistant both internally and externally and will require less maintenance and monitoring.
Power and Water kept some 9,000 stakeholders informed throughout the duration of the project, including individual households, local community groups and organisations.
