Ymir Water System

Annual Drinking Water Information

Ymir Water System 2019 Annual Drinking Water Information Brochure.

Size and number of connections

The system services 107 active connections.


The system is located in the community of Ymir between Nelson and Salmo and is within RDCK Electoral Area G.


The Ymir system currently draws water from an intake located in Quartz Creek. The Quartz Creek area is designated as a Community Watershed. Because of the susceptibility of surface sources to environmental contamination, the system was on Boil Water Advisory from 1995 until 2009, when the new treatment plant was installed.

System description

The system was first constructed in the 1890s to supply water to an expanding mining community. Several stages of upgrades have been performed since that date. The system became a RDCK service in 1979 after a cold winter that froze the entire system and left the community without water for up to six weeks.


A new water treatment plant was installed in Ymir in December, 2009. The plant includes pressurized media filters that are cleaned by a backwash process, 1-micron nominal cartridge filters, and 1-micron absolute cartridge filters. 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 Ymir Water Treatment Plant has received several awards, including the BC Water and Wastewater Association award for small water systems.


A concrete dam across Quartz Creek provides a small intake reservoir. The system also includes a 600,000 litre tank for treated water. 

Distribution system

Ymir's distribution system was gradually replaced in a series of recent upgrades. It now includes approximately 4.8 kilometres of PVC pipe.


The system's water pressure and storage capacity meet standardized requirements for fire protection. The distribution network serves 16 fire hydrants. The Ymir water system has been recognized by Fire Underwriters Survey as having a Dwelling Protection Grade since 1986 and has most recently been reviewed in 2014. Subscribing insurance providers can get water system grading information from Fire Underwriters Survey.

Significant issues

BC Timber Sales is planning a logging development in the Ymir Water System watershed. The RDCK is working with BC Timber Sales and the Ymir community on this issue.

Plans for future upgrades

The Regional District was successful in obtaining a Clean Water & Wastewater Fund (CWWF) grant in March 2017, in the amount of $642,964! The resulting construction of the 600,000 litre reservoir was completed in spring 2018.

A minor fire hydrant upgrade and infill project is planned for 2019.

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 Ymir Water Commission of Management.
