Knights Drain flood mitigation works

Flood mitigation works have started in the Knights Drain catchment, an area at greater risk of flooding since the earthquakes, due to ground subsidence.

Works have been split into three stages:

Stage 1

A new pump station and pressure main on ANZAC Drive to discharge water from Knights Drain into the Avon River.  

Stage 1 was completed by SCIRT in 2017.

Pump Station Anzac Drive

Stage 2 is under construction, due for completion mid-2018.

Stage 3 is currently undergoing design and property purchase negotiations.

The Knights Drain construction programme is dependent on property purchases progressing.
