The Tunstall Bay water system services about 150 users in the Tunstall Bay neighbourhood. 

Water for the Tunstall Bay system is supplied by six deep wells and a surface well. It is treated by filtration and chlorination at the source and then stored in a reinforced concrete reservoir. Some deep wells do not have chlorination, therefore chlorinated and unchlorinated well water is mixed in the storage tank. It is tested for chlorine residuals every day and samples are sent to Vancouver Coastal Health once a week.

Help us contact you quickly if we discover a leak

Bowen Island Municipality is currently dealing with leaks at some properties in Municipal water systems. We make every effort to contact the property owners, however in many cases we only have mailing addresses.

Please provide your contact information so that we can contact you by phone or e-mail if we discover high water usage on your water meter.

If BIM identifies a leak, every effort will be taken to contact the property owner. If the property owner cannot be contacted, water will be turned off at the property.
