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

Installation of the sewer main is progressing along Ohoka Road through the Williams Street/Ohoka Road roundabout. This stage of work is expected to be completed on Friday 5 May 2017.

There will be no through traffic on Williams Street during this time and detours will be in place. Work will be carried out between 9am and 4pm while traffic flows are low.

Traffic impacts

Traffic will be detoured to allow crews to install the new sewer pipe through the roundabout.

  • Northbound traffic on Williams Street will be detoured via Ohoka Road, Peraki Street and Carew Street.
  • Southbound traffic on Williams Street will be detoured via Ohoka Road, Stone Street and Courtenay Drive.
  • There will be no right hand turns at the roundabout.
  • On-street parking will be temporarily affected in the work area.
  • Please follow on-site signage.
