Waimate West Water Supply Reticulation Renewal (Palmer Road)

2026-11-03

The South Taranaki District Council (STDC), as part of its ongoing Road Rehabilitation Programme, proposes to renew a section of the water supply reticulation network at the intersection of Skeet Road and Palmer Road. The renewal is being undertaken in conjunction with planned intersection concrete pavement works, providing a practical and cost-effective opportunity to replace aging water infrastructure while avoiding future excavation and reinstatement costs.The works involve the decommissioning, or abandonment, of approximately 68m of existing DN200 asbestos cement (AC) water main located on Palmer Road at its intersection with Skeet Road, and the installation of a new DN250 HDPE PE100 SDR11 PN16 water main.The scope of works includes the supply and installation of all necessary valves, fittings and associated appurtenances required to integrate the new pipeline into the existing water supply network while maintaining continuity of service to customers.The new pipeline may be installed using open trenching or trenchless methods, such as Horizontal Directional Drilling (HDD), subject to site conditions, traffic management requirements, existing underground services, and approval by the Engineer. The works will include all excavation, drilling, pipe installation, network connections, testing, reinstatement, flushing, pressure testing, disinfection, and commissioning necessary to place the new water main into service.Additional deliverables include the full reinstatement of all disturbed areas outside the road rehabilitation footprint, together with the provision of as-built drawings, asset data, componentisation records, and supporting quality assurance documentation in accordance with Council requirements to support ongoing asset management and future maintenance.
