Ashburton Relief Sewer Project Update 2 September 2021

Published: 2 September 2021

Work on the Ashburton Relief Sewer (ARS) line has re-commenced following the Covid 19 Level 4 lockdown when the contractors were unable to operate.

With work recommencing, the intersection closure on Beach Road East/Beach Road will be put in place from Thursday, 2 September. Please refer to the details below.

The overall project remains on track to be completed by March 2022.


Despite the delay, Ashburton Contracting Ltd (ACL) is making good progress along Albert Street, with the pipelaying in the street to be completed this week before the work moves into adjacent land.


The Seipp Construction team has recommenced working in two locations along Milton Road South, laying the section of wastewater pipe that will run from the Ashburton River through to Wakanui Road where it joins ACL's portion of the laid pipe.

The intersection of Milton Road South and Beach Road will be closed to all traffic from Thursday 2 September for approximately five weeks.

Traffic will need to detour via Cochranes Road, Wakanui Road, or Trevors Road depending on where drivers are traveling to.

Milton Road South from the river to the Beach Road intersection remains closed to traffic (except for residents). It will reopen at the end of December.

Milton Road South between Beach Road and Wakanui Road remains closed to all traffic (except for residents). This section of the road will reopen at the end of November.


Please note, while we don’t anticipate any delays, they can happen and the above periods may be extended if the contractors encounter unexpected issues. Adverse weather events can also delay work.
