Parnham Lane Sewer Rising Main

A project is underway to install a new 1.4km sewer rising main in Kaiapoi, from the Parnham Lane Pump Station, along Vickery Street, Ohoka Road and Charters Street, and will connect to an existing pipe near the Kaiapoi River on Raven Quay. The project is expected to be completed in September 2017.

This is to replace the existing rising main which has reached the end of its useful life. The existing sewer pipe, installed in 1986, is located in an area that suffered significant earthquake damage and needs to be replaced.

This sewer main is a critical pipe that serves approximately 40% of Kaiapoi residents, including the Kaiapoi West, Parnham Lane, Kaikanui and Sneyd Street residential catchments.  The new pipe, made from polyethylene, will increase capacity and provide a more resilient wastewater system to these residents.

Work underway

From Monday 10 April, two pits will be excavated in the centre of Ohoka Road between Vickery Street and Willock Street to allow the new pipe to be drilled underground from each pit. A section of piope will be installed using open trenching from the intersection of Vickery Street and Ohoka Road heading east. Due to the location of the work, traffic detours will be in place.
