This module outlines a checklist of items that you and your licensed water well contractor should discuss and agree to before starting any drilling. A clear understanding between both parties is crucial so there are no misunderstandings or false expectations. Disagreements can arise between licensed water well contractors and well owners after the well is drilled because they simply did not take the time to thoroughly discuss all aspects of the drilling operation ahead of time.

Water wells are far more than a deep wet holes in the ground. They are an important and significant investment for any household or farm. Well owners should take the time to ensure they understand what they are purchasing. Money spent on high quality well design and construction materials is money well invested. A low cost well may not deliver the quality,
quantity or reliability you need.

A Water Well Drilling Agreement covers the topics you should discuss with your licensed water well contractor before any work begins. A blank copy of an example agreement is included at the back of this module and in the pocket on the back cover. Many contractors have their own version of a Water Well Drilling Agreement.
