Before you hire: wells and water pumps

Drilling a well falls under subcategory 2.1, other water catchment works under 2.2 and pumps under 2.3. A municipal authorization is generally required, and the driller must give you a drilling report.

Give the depth of the well if you know it, the flow you see, the problems (cloudy water, low pressure, a pump that starts often) and the date of the last water test. Have the water tested after any work on the well.

Licence subcategories for this trade: 2.1 Drilled wells, 2.2 Non-drilled water catchment works, 2.3 Groundwater pumping systems.
