Source, Treatment and Distribution

Water is pumped from a groundwater well directly into the distribution system as it fills the reservoir.  If the well is not running, water is gravity-fed from the reservoir to the distribution system.The water does not currently require any treatment.

As directed by the Island Health Authority a backup chlorination system is in place should disinfection be required.

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 for immediate response by CVRD-staff.
