Private Wells

Outside of the Public Water Supply Systems in Anola, Dugald and Oakbank, remaining Municipal residences and businesses rely primarily on private wells for their supply of water.

It is the responsibility of the private well owner to carry out a regular program of well maintenance to ensure well safety and understand well water quality. Taking care of your well is a three-step process:

  1. Protect your well water at the ground surface by avoiding, eliminating, or reducing contaminants.
  2. Inspect your well regularly and keep your well in good running order.
  3. Test your well water regularly and respond to water quality problems.

As a well owner, it is your responsibility to protect groundwater by being informed and Well Aware, click below to read more!

Well Water Testing

The province recommends testing wells and cistern water for the presence of bacteriological contaminants at least once a year. Preferably, the sample should be taken when the system is most vulnerable to contamination, e.g., during spring melt or following a period of heavy rainfall. Additional testing should be conducted if the well or cistern has been affected by flooding or if there is a noticeable change in the water’s taste, colour, odour, or clarity.

Private surface water systems should not be used for drinking unless you are absolutely certain the water has been properly filtered, disinfected, and ongoing water testing has demonstrated that the water is safe to drink. If you are consuming treated surface water, as a minimum, a water test should be conducted every change of season and following any maintenance completed on the treatment system.
