Well Maintenance

Well owners are responsible for the condition of their well and proper maintenance.

As your well ages, it may become damaged and allow harmful contaminants into your drinking water. Proper maintenance includes:

  • ongoing observation of the state of the well, pump and other equipment
  • keeping surface water or foreign materials from entering the well  (e.g., making sure the well cap is securely in place)
  • ensuring the minimum casing height, usually 40 cm, above the surface of the well is maintained
  • preventing contamination of the well from things such as vehicles, manure, pet waste, pesticides, salt or fertilizer
  • noticing changes in the appearance of the water such as colour, taste or odour, especially after a rainstorm or snow melt
  • testing water quality at least three times a year
  • ensuring your septic tank system works properly and is pumped regularly
  • identifying abnormal sounds which could indicate wear on the well’s pump, waterlines, electrical cables and associated equipment
  • verifying the pump’s efficiency – if the pump is continually running or losing pressure it may be a sign of a crack or hole in the waterlines
