Written Contracts


It is important to obtain a written contract when preparing to have a well constructed. Unless you know what each contractor will do for his specified price, you cannot compare offers and decide which one to hire. NGWA makes available standard contract forms to its members. For a drilled well, the contract might include:

  • Liability insurance coverage held by both the owner and the
  • contractor
  • A statement that all work is to comply with local and state
  • regulations and codes
  • The diameter and well thickness of the casing to be used
  • The type of well development and yield evaluation procedures to be used
  • The type of screen to be installed, where needed
  • The type of well cap or seal to be provided
  • The disinfection procedure
  • The cleanup after drilling, which includes all material abandoned without authorization at a drill site except drill cuttings and wastewater
  • An anticipated date for start of drilling
  • A guarantee of materials and workmanship. The contract should specify that the contractor will return to do or to correct the initial work if necessary
