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. A pilot project was started on September 11, 2017 to bypass the greensand filters and use a sequestering agent for the treatment of the iron and manganese.

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.
