South Slocan Water System

Annual Drinking Water Information

South Slocan Water System 2017 Annual Drinking Water Information Brochure.

Size and number of connections

The system services 51 active connections.


The system is located in the community of South Slocan within RDCK Electoral Area H.


The South Slocan system currently draws water from Watt's Brook and Smokey Creek as a secondary source.

System Description

This system was first constructed prior to 1950 and became a RDCK service in the 1980s. In order to address significant and persistent issues with historic water quality and quantity, the system recently underwent significant upgrades.


As part of the recent upgrades, a new water treatment plant was installed in South Slocan in July, 2010. The plant includes three filtration banks consisting of a backwashable sand media filter, a 1-micron nominal cartridge and a 1-micron absolute cartridge. UV disinfection and residual chlorine disinfection provide a microbiological barrier. The plant also uses a SCADA system, which allows for remote monitoring of plant processes.


The system includes a 273,000 litre steel reservoir that holds raw water, and a 300,300 litre steel reservoir that holds treated water. This second reservoir was installed during the recent general upgrade to the South Slocan system.

Distribution system

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.

Significant issues

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 water conservation strategies. Recent increased turbidity from the Watt's Brook spring source has resulted in increased filter replacement costs.

Dam safety regulations introduced a few years ago require that a dam safety review be completed for the Smokey Creek Dam. The Regional District has made multiple submissions to the Ministry of Forests, Lands and Natural Resources but these have not been accepted. Since the start of this project new dam safety review guidelines have been introduced and it has been recommended to us that a consultant specializing in dam safety reviews will need to be commissioned.

Plans for future upgrades

Construction of the South Slocan Treated Upper Zone project was started in 2014. New booster pumps have been added at the treatment plant to supply treated water to the upper zone. New 2” water line construction in the Treated Upper Zone Project was started in 2014 and completed in the fall of 2015.

The new 50mm HDPE water line runs from the Treatment Plant located just above the Old School House off South Slocan Village Road and runs approximately 2 km NE to its end point at a standpipe on the east end of 3453 Yeatman Rd. This line was installed to supply potable water to properties on Yeatman Road who were formerly using raw untreated water from Smokey Creek. Currently 1 commercial property and one property with 2 residences on it are serviced from the new treated line.


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.
