South Slocan Water System
Annual Drinking Water Information
Size and number of connections
The system services 51 active connections.
The system is located in the community of South Slocan Village approximately 30 km southwest of Nelson and is within RDCK Electoral Area H. The Dam Inn is across Highway 3A and is supplied water from this water system.
The South Slocan system currently draws water from Watt's Brook and Smokey Creek as a secondary source.
In order to address significant and persistent issues with historic water quality and quantity, the system recently underwent significant upgrades.
For more information on the South Slocan system, see presentation provided at October 21, 2019 Community Open House HERE.
A new water treatment plant was installed in South Slocan in July, 2010. Treatment includes sand filters and nominal cartridge filters for turbidity reduction, absolute cartridge filters for physical removal of some microbiological components, ultraviolet light for disinfection/inactivation of mirobiological componenets, and chlorination for disinfection of bacteria and viruses.
The system includes a 273,000 litre steel reservoir that holds raw water, and a 300,300 litre steel reservoir that holds treated water.
The system includes steel, cast iron, and PVC piping. Some sections of the distribution system were replaced in 1992 and 2003. New piping was also installed as part of the recent upgrade. Historic reports suggest that some piping has been subject to the types of maintenance issues that accompany aging distribution systems.
Existing fire-fighting infrastructure includes five hydrants and two standpipes. The flow and storage capacity of the system is inadequate to provide reliable fire suppression. However, the FIre Underwriters Survey reviewed the system in 2014 and is now recognized as having a dwelling protection grade based on available fire flows from one hydrant located near the old school house. Please contact your insurance provider for additional information.
Watt's Brook, the source for the South Slocan water system, provides limited flow. Especially during certain seasons, the system is nearing capacity for demand. Usage in the community is high and, as a result, this system could benefit from the implementation of advanced water conservation strategies.
A dam safety review was completed for the Smokey Creek Dam resulting in the rick classification being lowered from high to moderate due to the location of the highway below the dam. A moderate classification requires regular safety inspections.
Disposable cartridge filter consumption has been high for the past few years. Initially, it was believed the increase in filter consumption was the result of a slight turbidity increase after reconstruction of the Watt’s Brooks intakes. More recent data is indicating that raw water turbidity is down to near normal levels but water consumption is significantly higher in recent years. The increase in water consumption might be contributed to both warm weather demand and an increase in system leakage, which in turn contributes to increased filter consumption.
South Slocan has been facing significant rate increases in recent years that can be attributed to financing to fund the upper pressure zone upgrades, increased filter consumption, and an increase in distribution system and treatment plant repairs.
Plans for future upgrades
The South Slocan water system is aging, but there is inadequate funds in reserves for an upgrade program with the exception of a small distribution upgrade project around 2021.
Asset Management Planning
An Asset Management Plan (AMP) is complete and being updated annually. The 2018 AMP summary report can be viewed HERE.
The RDCK has received grant funding under the Federation of Canadian Municipalities (FCM), Municipal Asset Management Program (MAMP) in 2018 to develop a Risk & Criticality Assessment model for the water system's distribution network. This Risk & Criticality Assessment model is now a component of the AMP and is included when RDCK management considers asset replacement dates or the prioritization of upgrade work on the highest risk/highest need.
This system is currently owned and operated by the RDCK. The RDCK receives community-specific advice and policy guidance from the South Slocan Commission of Management.
