Dogwood Ridge Water System
Dogwood water system is a small water system located south of Duncan, in Area E, and services 33 residential properties.
Source, Treatment and Distribution
The water source consists of two groundwater wells. Water from the wells is pumped to the treatment building, where it receives chlorine disinfection and stored in a 227 m3 steel reservoir. The water is then pumped to the system as required by the customers.
Critical equipment is monitored 24-hours a day for malfunctions, such as high or low chlorine levels or pump failures; if such an abnormality occurs, an alarm is immediately sent to the on-duty pager to alert CVRD-staff for quick response.
Water Quality Testing
Dogwood water system is sampled, at a minimum, once a week. The following table shows the sampling frequency and parameters tested for the water system:
| Frequency | Parameter Tested | Laboratory |
|---|---|---|
| Weekly | Bacterial (E.Coli and Total Coliforms) | Samples are submitted to Island Health for testing by a provincial laboratory |
| Annual | Full spectrum analysis based on the Canadian Drinking Water Guidelines. Sampling of the source and distribution is alternated each year. | Bureau Veritas |
Testing results can be found in the Annual Water Report completed each year.
Fee Structure
Dogwood water water system is a fully metered water system meaning each connection has a water meter that records water consumption. Water meters are read every six months and customers are charged according to their consumption and based on the rates set out in the inclined block rate table (see below for details).

Undetected Leaks
Undetected Leaks will be considered in any buried service water line or water line in the building's walls. Plumbing fixtures are taps, toilets and hose bibs.
User Charges may be adjusted where an undetected leak on the consumer’s property has resulted in water usage greatly exceeding typical usage of water, according to the applicable classification(s) and there is no indication that water was knowingly allowed to run to waste. A request for a leak adjustment may be granted if all the following conditions are met or in extraordinary circumstances approval of the Corporate Financial Officer or the Manager.
- The property owner has not been granted a leak adjustment in the last 5 years.
- The leak was repaired within 30 days of billing or discovery of the leak;
- Written verification describing the nature of the leakage and the action taken to rectify the problem must be received by the Manager before a leak adjustment will be granted.
Where a leak adjustment is approved, User Charge adjustments will be determined as follows:
- If the leak is found in the service line, volumes from the 2 previous years, of the same billing cycle, will be averaged and charged. i.e. Average of 2 previous summers, if leak occurs in the summer.
- If the leak is associated with an in-home plumbing fixture or irrigation system, volumes from the 2 previous years, of the same billing cycle will be averaged plus 50% of the incremental water usage (between the average and the overage) will be charged to a maximum added value of $500.
- Subsequent leaks occurring within 5 years of the previous leak adjustment request will be eligible for the cap of $1,500 per single family dwelling equivalent, up to a maximum of $5,000. Where the average of the 2 previous years of the same billing cycle is greater than $5,000, the eligible cap will be 1.5 times the average.
