Water Main Renewals – Southshore
CN4600003512 – Christchurch City Council
The Southshore Watermain Renewals project was awarded to UINZ in February 2021. The project consisted of 3.8km of DN180 watermain and 0.8km of DN63 submain including more than 10 major connections to the existing network. The pipe was successfully installed using both in-house trenchless technology and open trenching methods.
UINZ successfully utilised trenchless technology to reduce the impact and risk presented by ground conditions, including an extremely shallow water table and running sands. The methodology also reduced the impact to the local community and traffic congestion within the area of Southshore.
UINZ achieved ZERO service strikes with its trenchless technology.
With the trenchless methodology, UINZ delivered significant a reduction of the project’s carbon footprint by eliminating the requirement for trench and road reinstatement. This also reduced carbon emissions from congestion to local traffic.
