Erickson Water System

Public Meeting - June 21, 2023

The RDCK invited users on the Erickson Water System to attend a public meeting on June 21, 2023 to discuss system challenges, projects and rate settings.  See below for a copy of the slide show presentation and public feedback form.

System Description and Governance

The system was first developed in 1929 by the East Creston Irrigation District, and later became the Erickson Improvement District with the amalgamation of the Erickson Irrigation District. The system was converted to a Regional District service in 2003. 

In 2005 a new water treatment plant was commissioned on Arrow Creek following a referendum in which water users considered multiple options for treatment. This plant now serves the Erickson community as well as the Town of Creston.

Governance changes were implemented starting in 2022, including the establishment of an overall Water Services Committee to represent all Regional District owned water systems and convert some Water Commissions of Management to a Water Services Community Advisory Committee.

The RDCK maintains a separate office for management of the Erickson water system. This office can be reached at (250) 428-2612. 

Annual Drinking Water Information

Size and Number of Connections

The system services 655 active connections and is the largest of the water systems managed by the Regional Distrtict.


The system is located in Erickson just outside the eastern border of Creston, crossing the boundary of RDCK Electoral Areas B and C.


The Erickson Water System derives source water from Arrow Creek, which is classified as a Community Watershed. The creek has benefited for several years from an ongoing water quality monitoring program. Historic water quality data for Arrow Creek indicate that the water quality falls within acceptable levels identified in the Canadian Drinking Water Quality Guidelines. Arrow Creek is susceptible to low flows during drought years, which could impact drinking water supply during high water demands. 

Agriculture Water Demand Study

Completed in December, 2019, the priority of the Erickson Water Service – Agriculture Water Demand Study report was to evaluate the current and potential agricultural water demand requirements in the Erickson Water Service area.  The Erickson water service is facing increased development pressure within the existing service area boundary as well as from neighbouring non-RDCK water systems.  The region is presently experiencing growth in the tree fruit sector and these demands, in addition to the influence of climate change impacts will place an increased pressure on the water supply and delivery system.  To assist in planning for and managing a sustainable water service over the long term, this study was completed to evaluate current and projected potential agricultural water demand in Erickson.

The Arrow Creek Treatment Plant is operated at capacity for long periods of time during hot weather, and Arrow Creek is susceptible to low flows during droughts. The Regional District is exploring universal metering implementation to help control water demand and identify leakage.


The treatment process includes coarse screening, settling and fine screening for turbidity reduction in two Arrow Creek intake settling ponds, membrane filtration for physical removal of microbiological components, and ultraviolet light and chlorination disinfection of bacteria and viruses. A System Control and Data Acquisition (SCADA) unit allows for remote plant monitoring and operation.

Water Quality Monitoring


Two enclosed reservoirs constructed in 2017 provides storage for the Erickson system for fire fighting and additional water during peak demand periods.

Distribution System

Eleven (11) kilometres of mainline providse drinking water to residents of the Erickson community and the Town of Creston. Several kilometers of the pipeline, originally constructed in 1929, were replaced in a multi-phased project beginning in 2008 and completed in 2018. The distribution system was originally designed to operate as a flume and not as a pressurized system; the mainline replacement reduced system leakage by over 50%.  The Erickson distribution system has 32.6 km of PVC, asbestos cement and steel pipe.  A few pipes date back to 1929 and most pipes were installed in the 1960s and 1970s.


Storage and pressure in the Erickson system meets standardized requirements for fire protection in some areas. For more information contact your subscribing insurance provider.

Significant Issues

The Arrow Creek Mainline project addressed a significant issue in the Erickson Water System. However, there still remains asbestos concrete and steel watermains in the distribution system that are at or nearing end-of-life which need to be replaced. The distribution system pipes can also be considered under-sized resulting in lower pressures for some customers during high water demands.

Plans for Future Upgrades

  • Sections of asbestos concrete and steel watermains that are at or nearing end-of-life will be replaced over the next several years.
  • Phased water meter implementation 

Asset Management Planning

An Asset Management Plan is complete and updated annually. The Asset Management Plan identifies required asset replacements over a 25 year and 100 year period and identifies annual contributions to water system reserves required to fund the replacements.
