New wastewater infrastructure for Wellington CBD
We will start construction of a new rising sewer main for the Wellington CBD in July.
The rising main (pipe which conveys sewage under pressure from a pumping station) will be constructed from the Whitmore and Featherston intersection up Whitmore and Bowen Street to connect to the main interceptor sewer outside the Bowen Campus.
Rather than a repair, this project is an investment in new infrastructure to build resilience and capacity into the sewer network within Wellington’s CBD.
The project is the first of a series of planned upgrades over the coming years to rising mains in the CBD. These mains connect to the main sewer interceptor that conveys wastewater from Johnsonville through the CBD to the Moa Point treatment plant.
The work will require the closure of two of the four lanes along Whitmore and Bowen Streets, but there will be continuous through flow of traffic each way. Traffic management will be in place 24/7 along Whitmore and Bowen Street while the works are being carried out. As always we apologise for any disruptions but hope people will be patient as we carry out this critical work investing in our city’s future. And we encourage drivers to avoid the area or travel at non-peak times where possible.”
Starting in July the works are expected to continue for six months.
Several other unrelated construction projects are also underway in the same corridor including the tower block development at the former Z Energy site. We have worked closely with Wellington City Council to ensure projects are co-ordinated to minimise impacts on businesses and travellers.
