HDPE pipelines were manufactured in 100m lengths on site and transported using dollies to their final locations.
The headrace canal was build during the Stage 1 Construction phase. The canal was constructed by a Joint Venture between Fulton Hogan Ltd. and John Holland Australia.

Stage 2

A completed on-farm Turnout
Installation of the GRP Pipeline
A new canal offtake (Offtake 5) was constructed into the existing Headrace Canal to supply the Stage 2 distribution network.
Large isolation valves up to 2.5 metres diameter are installed at regular intervals along the GRP pipeline.

Land access required to install the Stage 2 GRP pipeline required a 50 metres wide construction corridor.
The Stage 2 GRP pipeline (line 5) was constructed from glass reinforced pipe (GRP) up to 2.5 metres in diameter. The GRP pipeline is 23 kilometres long and supplies all of the Stage 2 distribution network.

NIWA staff undertaking annual fish barrier compliance monitoring. The CPWL Environmental team work closely with the Operations and Maintenance team to ensure that all our activities meet the requirements of our consent conditions.
The inlet to the Storage Pond includes an inlet structure and erosion protection structures.
Construction of the inlet pipe into the Sheffield Storage Pond required excavation under the KiwiRail railway lines.
The Sheffield Storage Pond is fully lined with HDPE Liner to prevent leakage. The liner is held down with rows of rock material and is placed on a geotextile liner to prevent puncturing.
The Sheffield Storage Pond was fully commissioned in 2018 and provides up to 12 days storage to the Sheffield Water Scheme.
