Lambourn Water System

Lambourn Water System

Lambourn water system is located south-east of Cowichan Bay in Area D. The water system services 160 single-family dwellings and a mobile home park.  

Source, Treatment and Distribution

Lambourn water system receives its water from three groundwater wells. The water is pumped up to the treatment building where there are provisions for the water to go through a greensand filtration system for the treatment of iron and manganese. Since September 2017, a sequestering agent has been used for the treatment of the iron and manganese in the supply water. The water receives chlorine disinfection before being pumped to two reservoirs and fed to the distribution as required by the customers.

Community Works Gas Tax and reserve funding is in place for reservoir replacement and pipeworks in 2023.

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 sent to the on-duty pager to alert CVRD staff immediately.  

Water Quality Testing

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

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.

  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.
