Tunstall Bay Water System

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.

Changes to your water bill in 2017

With the adoption of the Tunstall Bay Annual Water Rates Bylaw No.431, 2016, Tunstall Bay water billing has changed to a hybrid metered rate. Bills will be sent four times a year, and will include a fixed flat rate plus an additional charge for each gallon of water used.

Flat and metered rates

In 2017, the Annual Flat Rate is $700 per year.  Over time, as metered rates are fully implemented, this amount may be further decreased.

The metered rates are:

 Gallons/month  Rate
 0 - 1500  $0.00245
 1501 - 3000  $0.00441
 3001 - 4500  $0.00613
 4501 - 6000  $0.00784
 6001 and over  $0.00956

How much water do you use?

Three years of meter readings were recorded in order to determine an average use per household, and we calculated that 7 out of 10 properties use less than 125 gallons per day.

How much will you pay?

You can view your average use if you have your utility account number. You can then estimate how much you will be charged based on the following:

 Gallons per day  Annual charge
 50  $744
 75  $784
 100  $823
 125  $879
 150  $934
 175  $1004
 200  $1074
 240  $1212
 300  $1419

The estimates above include both the flat and metered rate for the year.

What if your property is a vacant lot?

The new hybrid rate will impact owners of vacant land located within Tunstall Bay. Unconnected Properties will be levied a standby charge equal to 60% of the Annual Flat Rate ($420) in 2017. Standby charges will be contributed to the infrastructure reserve fund, and used to ensure the system is well maintained and can provide services to those properties when they eventually connect.

Why change to metered rates?

Last year, Council asked us to review all Municipal water rate bylaws with a view to developing uniform and consistent charges for all Municipal water users. Tunstall Bay is the first water system (outside of Cove Bay) to switch to this hybrid billing system. Switching to metered rates:

  • promotes a culture of water conservation
  • improves leak protection
  • develops consistency Island-wide
  • distributes costs more equitably

The Tunstall Bay Water System Local Advisory Committee has advisory powers to Council regarding water system issues, and also reviews the operating and capital budgets for the utility. The Committee meets two to three times a year, including an annual information meeting where any users of the Tunstall Bay Water System are welcome to attend.
