Wastewater Scheme Upgrades

The following future project is budgeted and/or included in the Long Term Plan 2015-25.

Capacity issues with the Tinwald trunk main and the Ashburton relief sewer were identified in 2008.

The Ashburton relief sewer is a trunk sewer main running from Creek Road (at Saunders Road) to the end of Trevors Road, a total length of 4,920m.

The Ashburton relief sewer will be fully upgraded in 2016 at a cost of $3.7 million (after inflation adjustment).

There will be an additional relief sewer built from Grove Street in Tinwald. The expected cost will be $720,000 (after inflation adjustment).

These wastewater scheme improvements will improve the service provided to properties. The Ashburton relief sewer will also cater for future flows from the Ashburton Business Estate and the proposed new residential zones around the south-east of Ashburton.​
