A $12 million wastewater scheme is ready to service the household needs of about 14,000 new and existing residents in Westmorland and Halswell.

The South East Halswell Wastewater Scheme features eight kilometres of new pressure sewer mains pipe, which is up to 450 millimetres in diameter, and a new pump station in Sparks Road.

The sewer pipes link three pump stations and allow for subdivision connections.

The project also delivers a new water supply main through the Sutherlands Road corridor and Quarry View boosts reticulation and also supplies the new subdivisions.

Council Senior Project Manager Kylie Hills says work has just finished on the scheme, which has the capacity to service more than 5000 new houses in the area.

“The wastewater scheme accommodates new growth in Halswell's south-east and Westmorland, as well as taking the load off existing parts of the network, allowing for development elsewhere in the city,” Mr Hills says.

“The work was not without its challenges,” he says.

“We had to deal with trenching through swampy ground during one of the wettest winters on record, several significant road closures, challenging ground conditions and pressure to finish work in the Ngā Puna Wai section to be ready for the construction of the sports hub.

“However, we would also like to recognise everyone’s efforts in delivering the works safely, under budget and in good time.”

Existing pump stations in the area have also been upgraded as part of the project.

The scheme has the capacity to carry more than 11 million litres of wastewater per day.
