Rule 248. A dewatering well in an aquifer under an artesian head requires special installation practices. A dewatering well contractor shall take necessary precautions if he encounters a flowing artesian aquifer that flows above working grade, to prevent unreasonable waste of the water and to prevent damage of nearby properties or watercourses or both. Methods of construction and abandonment shall be determined in pre-construction conference with all concerned parties, including the consulting engineer, and shall be approved in writing by the department.
