Carlton Water System

Carlton Water System

Carlton water system is a small water system located east of Shawnigan Lake village, in area B and services 46 residential properties.

Source, Treatment and Distribution

The source water for Carlton water is two groundwater wells. The wells pump water up to the treatment plant where the water receives chlorine disinfection and continues to the reservoir where it is pumped to the distribution system and fed on demand to 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.

Water Quality Tests

Carlton water system is sampled, at a minimum, once a week. The following table shows the sampling frequency and parameters tested for the water system:

High Consumption Due to 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
