In June 2003, the Ministry of the Environment put into place the Groundwater Catchment Regulation, intended to manage the installation of artesian wells.

In summary, here are the principal elements to consider:

  1. Catchment work permit
    The owner must obtain a catchment work permit from the municipality to install a new well or to modify an existing well.
  2. Location of the well
    The well must be situated:
    a. More than 30 metres from any non-watertight wastewater system (septic leach or absorption field).
    b. More than 15 m from a watertight wastewater system (septic tank).
    c. More than 30 metres from a cultivated parcel.
    d. Outside of a flood zone.
  3. Sealing of the well
    As per the applicable regulation, a well must be sealed :
    • if the rock formation is less than 5 metres (16.4 feet) from the surface of the ground.
    • if the well is located less than 30 metres (but more than 15 metres) from a non-watertight wastewater system.
  4. Disinfection of the well
    Following the installation or modification of an artesian well, the contractor must clean and disinfect the catchment work in order to eliminate any contamination.
  5. Protection of the well
    The owner must ensure that the integrity of the cover is maintained at all times in order to prevent the infiltration of contaminants. The tubing casing must be at least 30 cm high above the soil at all times. The owner must ensure that the finishing grade, within a 1 m radius from a catchment work, is carried out so as to prevent the presence of stagnant water.
  6. Water analysis
    The owner of a catchment work must have groundwater samples taken between the second and the thirtieth day following the beginning of use of the pumping equipment and have the samples analyzed by a laboratory accredited by the Ministry of the Environment.
