Duhamel Water System
Annual Drinking Water Information
Size and number of connections
The system services 93 active connections.
The system is located in the community of Duhamel, on the north shore of the west arm of Kootenay Lake. Duhamel is within RDCK Electoral Area F.
The Duhamel system draws water from a 156-foot well. The area's aquifer is designated as being of high-to moderate vulnerability due to moderate levels of development. The source area is classified as a Community Watershed.
Insufficient information exists regarding the date when this system was first developed; however, some system components were upgraded in 2005.
Because the system draws from a groundwater source that is not under the direct influence of surface water, no filtration or disinfection is required. Historic sampling has confirmed that water quality from the Duhamel system is consistently high.
The system includes a 454,000 litre concrete reservoir. This level of capacity meets existing water demands in the area and could support moderate growth.
The distribution system is gravity fed from the reservoir. As a result, in the summer watering season, portions of the network at higher elevation are prone to low pressure problems. Reports suggest that the distribution infrastructure is in good shape but at half its expected lifespan.
The system does not meet standardized requirements for fire protection. However, the Duhamel water system was reviewed by the Fire Underwriters Survey in 2014 and is now recognized as having a Dwelling Protection grade based on available fire flows from one hydrant. Subscribing insurance providers can now get water system grading information from Fire Underwriters Survey so contact your insurance provider for additional details.
A significant proportion of water system infrastructure is situated on privately owned land in Duhamel. The RDCK is working to establish right-of-way agreements with property owners to ensure that utilities staff are able to legally access all aspects of the system in order to perform maintenance, upgrades, or emergency works.
Plans for Future Upgrades
No upgrades are planned for the near future.
This system is currently owned and operated by the RDCK. The RDCK receives community-specific advice and policy guidance from the Duhamel Water Commission. A network of volunteers operates and maintains the system.
