Hartley’s to Hororātā
Stage 1
Division: Three Waters
Client: Corde
Location: Whitecliffs Road, Glentunnel
Status: Completed 2026
Taggart carried out the open trenching for the Hartley’s to Hororātā Pipeline Project in the Selwyn District. The new drinking water pipeline connects the Hartley’s and Hororātā schemes, improving capacity, reliability and resilience for current users and future demand. A new fibre cable was also installed between Hartley’s and Coalgate, giving a more reliable way to monitor and control the network than the existing mobile-based system. Our team installed 2,100m of DN250 PE100 water main in the road reserve at 1.1m deep, along with communications pits at 500m intervals and eight crossings under existing culvert pipes.
We developed our own programme and tracked production against it throughout. Despite working through winter, weather didn’t affect the schedule, and we finished two weeks ahead of the planned completion date. That performance led to us being awarded the next stage and further work across the Selwyn District.
From start to finish
