Florida Administrative Code › 40 - WATER MANAGEMENT DISTRICTS › 40A - Northwest Florida Water Management District › Chapter 40A-3 - REGULATION OF WELLS › Part II - CONSTRUCTION, REPAIR, AND ABANDONMENT STANDARDS › Section 40A-3.507 - Casing and Liner Pipe Standards

Current through Reg. 50, No. 138; July 16, 2024
(1) For
				  the construction of water wells, well contractors shall comply with the well
				  casing, liner pipe, coupling, and well screen requirements in subsection
				   62-532.500(1),
				  F.A.C., which is incorporated by reference in paragraph
				   40A-3.504(3)(g),
				  F.A.C.
(2) For well casing or liner
				  pipe installed by driving, the casing or pipe shall not butt together inside
				  threaded couplings unless the joint is electrically welded so as to be
				  completely watertight. A drive shoe is required for use on pipe installed by
				  driving unless exempted by the District.
(3) Well casing installed by driving shall
				  not have less than the dimensions and weights specified in Table 1, and the
				  requirements of paragraph
				   62-532.500(1)(b),
				  F.A.C., which is incorporated by reference in paragraph
				   40A-3.504(3)(g),
				  F.A.C.

				  For the construction of water wells using PVC casing, well contractors shall
				  comply with the requirements of paragraph
				   62-532.500(1)(e),
				  F.A.C., which is incorporated by reference in paragraph
				   40A-3.504(3)(g),
				  F.A.C.
(6) Steel well casing and
				  liner pipe shall be joined in a watertight manner by threaded couplings,
				  electrical welding methods or other methods approved by the District. PVC pipe
				  shall be joined by heat welding, solvent bonding, threaded couplings or other
				  methods approved by the District, which shall meet the strength requirements of
				  the casing as specified in subsection (5), above.
(7) Nonmetallic and stainless steel well
				  casing or liner pipe shall not be installed or seated by driving unless it can
				  be shown the casing or pipe will maintain its integrity so as to prevent
				  degradation of the water resource. The Department of Environmental Protection,
				  under the provisions of paragraph
				   62-532.500(1)(f),
				  F.A.C., requires all alternative well casing, not listed in Table 1 to receive
				  Department approval prior to use. Prior approval for the use of alternative
				  materials shall also be obtained from the District.
