Lister Water System

Annual Drinking Water Information

Size and number of connections

The system services 197 active connections.


The system is located in Lister, within RDCK Electoral Area B.


The Lister water system used to derive source water from Lister Creek (also known as Floyd Creek), which is designated as a Community Watershed. For years, water quality testing indicated the presence of low level Coliform bacteria and E.coli.

In late 2012, the Regional District connected the system to a new groundwater well source. This new source has contributed to reducing the danger of contamination by wildlife and environmental sources.

System Description

This system was first developed in 1929 and underwent significant upgrades in the 60s, 70s, and 80s. It was converted to a RDCK service in 1982.


In 2014 the RDCK implemented chlorine disinfection of the Lister Water System. This enabled IHA to lift the Boil Water Advisory that had been in place since 2012.


Storage for the system used to be supplied by a dredged, unlined containment pond that was constructed in 1982. The pond was exposed to the open environment and algae growth was a problem during certain times of the year. The Regional District has since constructed a new closed steel reservoir tank with a capacity of 885,000 liters. 

Distribution system

The system includes approximately 30 kilometres of pipe. Some of this pipe was replaced in the 1980s. Reports suggest that the remainder of the distribution network may be nearing the end of its useful life. An asset management plan recently developed for Lister Water System identified a backlog of about $3.2 million in waterline replacements. This will be addressed in the coming years, as outlined in the Plans for future upgrades section below.


Existing fire-fighting infrastructure includes three standpipes; however, the system does not meet established guidelines for fire protection.

Significant issues

The well and reservior were designed based on BC Design Guidelines for Rural Residential Community Water Systems, but water demand in the Lister Water System is higher than what the system can provide. A new well pump was installed in 2016, increasing system pumping capacity from 280 gpm to 450 gpm.

The Lister Water System has high water consumption compared to the national averages. Single family dwelling accounts are for domestic use only, and includes irrigation of up to one acre. No commercial or agricultural water usages are permitted for single family dwelling accounts. 

Plans for future upgrades

An asset management plan recently developed for Lister Water System identified a backlog of about $3.2 million in waterline replacements. In response, a system assessment for the Lister Water System has been completed. The assessment, funded by the Lister Water System reserves fund, addressses watermain sizes and capacities, and potential pvc piping replacement. 

Related to the assessment, a preliminary study has also been undertaken to determine the feasibility of supplying water to neighbouring water systems. The reports are found HERE.

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 Lister Commission of Management.
