Good Progress on North West Ashburton Wastewater Treatment Project

Contractors working on the $3.285 million North West Ashburton sewage treatment project are ahead of schedule and have moved from Allens Road to Carters Road.

The project includes the laying of 2 km of pipes in the area and the construction of a new pumping station, so that waste water from current and future development can be routed to Middle Road, where it will enter the sewage system. existing sanitation of the city.

The first stage of work along Allens Road was due to be completed on October 11, but Tru-Line Civil contractors are ahead of schedule and reopened Allens Road to traffic on Friday October 7, four days ahead of schedule . The second leg is on Carters Road and the third leg is on Farm Road.

Traffic is now being managed on Carters Road while new pipes are being laid. The road is temporarily closed to all vehicles and pedestrians except residents, who still have access.

Council Infrastructure Services Group director Neil McCann said the project was progressing well and contractors had been working on Carters Road since late September, well ahead of schedule.

“This means we should be able to reopen Carters Road to traffic before our planned December 8 deadline, although the timing of the work is weather dependent and we have been lucky so far.

“The contractors will return to Allens Road around March to work on the pumping station.”

Mr McCann said contractors would continue to work with residents regarding access to properties while machines and work crews did their job.

“We really appreciate everyone’s patience as the project progresses. We know this can be disruptive at times and we are continuously coordinating with all affected residents as work progresses through its various stages.

The planned work phases all require traffic management on the following axes:

  • Carters Road, between Allens Road and Farm Road – until December 8
  • Farm Road, between Carters Road and Racecourse Road – December 9 to January 17, 2023
  • Farm Road, between Carters Road and Middle Road – January 18, 2023 to March 1, 2023
  • Allens Road, between Carters Road and Middle Road – March 2, 2023 to May 29, 2023

“We know that many people in the wider community also use the North West Zone for exercise, so we ask that they be prepared for some disruption to their usual routines as well.”

The new sewage line will allow for more residential development in the area, which is primarily zoned Residential C, and allow others to decommission their septic systems and connect to the new system.
