Denver Siding Water System
The Denver Siding Water System is under a
permanent Boil Water Notice
Village of New Denver - Denver Siding Boundary Extension
The Village of New Denver and the RDCK plan to seek grant funding for system upgrades which would allow for the Denver Siding Water System to be included in the Village of New Denver's boundary extension.
More information can be seen on the Village of New Denver's "Process and Timeline" document.
Annual Water System Information
Size and number of connections
The system services 21 active connections.
The system is located on Denver Siding Road, northeast of the village of New Denver. New Denver is within RDCK Electoral Area H.
The Denver Siding water system derives source water from Esthwaite Spring, Lloyd Spring, and Aylard Creek. Intakes on all three sources are relatively susceptible to rock slides and sediment intrusion. The supply area is designated as a Community Watershed.
Insufficient information exists regarding when this system was first developed; however, some system components were replaced in 1973. The system was converted to an RDCK service in 1993.
The Denver Siding Water Users drinking water is an untreated surface water source. As such, it is open to contamination by potentially infective doses of disease causing microorganisms at any given instance. Micro-organisms which cause gastro-enteric diseases in humans such as Campylobacter, Salmonella, and Giardia and Toxoplasmosis are known to be transmitted through drinking water that has been contaminated with the feces of domestic animals and wildlife, including birds and rodents. Infections in individuals are known to sometimes be asymptomatic, rather than acute. Such infections are known to sometimes result in long term health impacts on an individuals’ health. Examples are the inability to digest fat soluble vitamins (Giardiasis); Guillain-Barre Syndrome (a neurological disorder known to be triggered by Campylobacter Enteritis); and reactive arthritis (Salmonella).
Untreated surface water drinking water is not considered safe to ingest. A Boil Water Notice is recommended for Users to lower the health risk. The Boil Water Notice is intended to be a temporary risk mitigation measure, until steps have been taken to ensure the water is safe to drink.
Boil Water Notice
A boil water notice was issued to the residences of Denver Siding Water Users water system. This water system is not adequately treating the water distributed to its users. We recommend boiling the water for a minimum of 1 minute when used for:
- Cooking (if not boiled)
- Brushing teeth
- Washing dishes
- Washing fruits & vegetables to be eaten raw
- Making Ice cubes or juice from concentrate
The system includes a 136,000 litre dual chamber concrete reservoir that was hand-poured by volunteers in 1973. The capacity of the tank meets existing water demands in the area.
The system includes 2.1 kilometres of asbestos-concrete and PVC mainlines. Reports suggest that this infrastructure may be nearing the end of its life expectancy.
Existing fire-fighting infrastructure includes three hydrants and one standpipe. The storage capacity of the system, however, is inadequate to provide reliable fire suppression.
The Regional District and the Village of New Denver are currently reviewing the feasibility of amalgamation and the provision of potable water from the Village to Denver Siding. This option was identified as being more cost effective than building a separate water treatment plant for Denver Siding.
For the information of residents, the 2014 water sample results are presented in the table below.

Plans for future upgrades
In order to proceed with the amalgamation with the New Denver system, the Denver Siding distribution network would need to undergo the following upgrades:
- determine system demands
- develop an upgrade plan
- provide a condition assessment of the existing water system and reservoir
- revise the long term asset management plan
In 2013, the Regional District completed a Preliminary Design Study [PDF - 2.8 MB] containing cost estimates on various options to remove the Boil Water Notice from the water system.
On November 2013, the Regional District hosted an Open House with the Village of New Denver on the water quality upgrades. Please refer to the following link for the Open House Presentation [PDF - 1.7 MB].
This system is currently owned and operated by the RDCK.
