Burnum Water System
Burnum water system is located between Cobble Hill and Shawnigan Lake, in area B, and services 88 residential properties.
Source, Treatment and Distribution
Burnum water system receives its water from three groundwater wells. Due to the elevated levels of arsenic in the source water, a treatment system is installed at one of the wells to bring the arsenic level down to within the Canadian Drinking Water Guidelines. The water also receives chlorine disinfection before being pumped to a 365 m3 reservoir and fed on demand to the community.
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 immediate response.
Water Quality Testing
Burnum 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 the Island Health Authority for testing by a provincial laboratory|
|Two times a month (bi-weekly)||Arsenic|| AGAT Laboratories|
|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.
Up-to-date arsenic testing results can be found here
The arsenic sample results from August 1 to October 19, 2017 show the arsenic level above the Canadian Drinking Water Guidelines. The filtering media in the arsenic treatment unit, installed on well #3, was in need of replacement and was replaced on October 19, 2017.

|over 400 m3|| $450.00 + $2.25 per m3 over 400m3|
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.
