Pumping Main Installation Project for Reservoir Pipeline Replacement

The proposed contract is for the installation of a new pumping main to replace the existing aging pipeline, starting from the newly installed pipeline on the first terrace above the intake Reservoir at 1324 Greta Road, the pipeline will run west towards the farm entry gate on state highway, then to the top of the hill to connect to the first Reservoir, continue along the peak to the finish at the second reservoir.

The pipeline will consist of approximately 650 meters of DN225 PE100 PN25 running from the recently connected main on the first terrace and run towards the farm entrance, install a PN25 Sluice valve, Tee and drain/flushing point, continue west by installing small section of pipe through the recently installed sleeve crossing under the highway then uphill approximately 376 meters of DN225 PE100 PN20.

At the midpoint on the Hill change to DN225 PE100 PN12.5 then continue towards the 1st existing Reservoir approx. 280m and connect via the inlet pipework. Continue the pipeline west towards the 2nd Reservoir approximately 1190 meters of DN225 PE100 PN12.5 pipe where the final connection can be made.

The Hurunui District Council will supply the required DN225 PE100 PN25, the DN225 PE100 PN20 & the DN225 PE100 PN12.5, but the contractor must liaise with the pipe supplier for the timing of the pipe deliveries. The Contractor is to supply and install all valves, fittings, connections and to perform all required pipe welding Inc. any required welding test certs.
