📋 Tender Overview
Description : Repurpose PW601 to supply water to both Pressure Zone 1 (PW803) and Pressure Zones 8, 9 and 13 (PW810). Under this option, PW602 is decommissioned, PW605 remains unchanged, and the required capacity from PW660 will reduce by the demand from Pressure Zones 8, 9 and 13. An 800mm diameter HDPE pipe will be slip-lined inside the existing water main from PW601 for approximately 1.5km to a termination point on the north side of the Nechako River. From this termination point, the 800mm HDPE pipe would be conventionally trenched to a new pump station at the existing PW608 location. In this pump station, a 750mm stainless steel header will feed a 600mm takeoff to Pressure Zone 1. A 300mm stainless steel takeoff will supply booster pumps to feed Pressure Zones 8, 9 and 13 via the water storage reservoir at PW810.
