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 send 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:
|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 tap water is alternated each year.||AGAT Laboratories|
Testing results can be found in the Annual Water Report completed each year.

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)

High Consumption Due to Undetected Leaks
User charges may be adjusted on a one-time forgiveness basis, where an undetected leak on your property has resulted in water consumption greatly exceeding your normal consumption (for the billing period) and there is no indication that water was knowingly allowed to run to waste. Additionally, a cap of $1500 is in place for subsequent leaks after the first forgiveness of a water overage charge. Written verification describing the nature of the leak and the action taken to repair the problem must be received by the Manager before the forgiveness will be granted.
