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.

A new treatment building was constructed in 2022, funded by Community Works Gas Tax.

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:

Testing results can be found in the Annual Water Report completed each year.

Fee Structure

Carlton 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. Current year budget information can be viewed here.

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 of the following conditions are met or in extraordinary circumstances, upon approval of the Corporate Financial Officer or the Manager.

1. The property owner has not been granted a leak adjustment in the last 5 years. 
2. The leak was repaired within 30 days of billing or discovery of the leak.
3. 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:

1. 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.
2. 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.
3. 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.
