New supply, distribution, and storage system
Long standing boil water advisories and a high risk aquifer prompted the village of Belcarra to pursue a public drinking water supply. This project saw the design of a saltwater intrusion into private wells.
This project was the largest capital project ever undertaken by the village. The central component - the 1.4km long submarine ocean crossing - provides potable water to the village from the District of North Vancouver’s water system.
This component of the project was the most complex, involving environmental assessments, First Nation consultation, federal and provincial government permits, and approvals from the regional district.
The project included a pump station which services the high elevation pressure zone. This pressure zone is a closed system which required the design of pressure modulating pumps and the associated PLC control system. The pumps operate to maintain near constant pressure across a broad range of flows.
The facility also included an NFPA approved diesel fire pump system to meet the pressure zone fire flows.
