Well Water on Denman Island — What Every Property Owner Should Know
Understanding how your well works is part of island life. Municipal water isn't an option for most of Denman and Hornby, making you entirely responsible for your own water infrastructure.
Seasonal Water Table Drawdown
The aquifers on Denman Island drop significantly during the dry late summer months (August/September). It is very common for shallower wells to run dry. If this happens, your pump can burn out if it continues to run without water.

Agricultural runoff and dense septic fields mean water testing is critical. You should test your water annually for coliform bacteria and nitrates. For real estate transactions, a comprehensive water quality and flow test is standard practice.
Common Well Issues
- Waterlogged Pressure Tank: If your pump clicks on and off rapidly every time you run a faucet, your pressure tank's internal bladder has likely failed.
- Sediment: Silt in the water means you need a sediment filter installed before the water enters your home's main plumbing lines to protect your fixtures.
- UV Systems: To combat bacteria, UV filtration is installed on the main line. Remember to change the bulb annually!
