Keyes Road - New Brighton - Wastewater
A further update to this work notice that provides an overview of New Brighton work is available here
The existing wastewater pipe suffered multiple breaks in the February, June and December earthquakes. The replacement PVC (Polyvinyl chloride) pipe is approximately 1.1 kilometres long and runs between the pump station opposite number 356 Keyes Road and the intersection of Bowhill Road and Keyes Road. The work will take approximately five months to complete, subject to suitable weather and ground conditions along the pipeline.

To complete the gravity sewer renewal we need to dig trenches ranging from 1.5-5.5 metres deep. Dewatering, using spears and extraction pumping, will be required to drop the water table in the trench at all times. Excavation will proceed once the ground is dry, using trench shields. A new 225mm PVC pipe will be installed, then laterals will be renewed and attached at the private boundary. There may need to be some excavation done at your boundary, if this is the case we will be in contact with you. The work may result in increased noise, dust and vibration levels because of truck movements, the use of excavators, compactors and pumps.
Stay safe and alert, keep children and pets at a safe distance from the work site. Please do not allow children to play in any water around the site. If you wish to speak to someone on site please go to the person furthest away from any moving machinery.
