Waipukurau Second Water Supply, Tikokino Rd Rising main renewal - Phase 1, Stage 2&3

Council plans to replace and upgrade the existing Tikokino Road water rising main from the Waipawa Water Treatment Plant (WTP) to the point where the rising main leaves Tikokino Road and travels up the hill to the Waipawa reservoir. This project forms part of the overarching Waipukurau Second Water Supply Project.

The renewal will be effected in three stages:
• Stage 1 – Waipawa WTP to the intersection of the WTP access road on Tikokino Road (under construction)
• Stage 2 – Intersection of the Waipawa WTP access road and Tikokino Road to the proposed Waipawa/central reservoir branch connection on Tikokino Road
• Stage 3 – Waipawa/central reservoir branch connection to the point where the rising main heads off Tikokino Road up the hill to the Waipawa reservoir

This Contract is for Stages 2 and 3 of the Tikokino Road pipeline renewal.

The project activities will include (but are not limited to):
• Potholing and locating existing services before commencement of construction
• Construction of the new rising main (DN 400 PE 100 and DN 280 PE 100) along Tikokino Road by open trench methods
• Construction of connections to Stage 1 and the existing DN 225 AC Watermain at the Waipawa end
• Construction of valves (drain valves, main line valves) and associated structures
• Remove redundant fixtures and cap existing pipes
• Removal of section of asbestos pipe as required for connections to the existing pipe.
• Testing and commissioning.

265 m of DN 400 PN 12.5 PE 100 pipe was purchased by Council under the Stage 1 contract and will be made available for installation under Stage 2 & 3 contract (Principal supplied item).
