Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-532 - WATER WELL PERMITTING AND CONSTRUCTION REQUIREMENTS › Section 62-532.500 - Water Well Construction Standards

Current through Reg. 50, No. 138; July 16, 2024
The following minimum standards shall apply to the
				  construction, repair, and abandonment of water wells in the State unless
				  exempted by a water management district rule with the concurrence of the
				  Department. Operation requirements for public water systems are included in
				  Chapter 62-555, F.A.C., and operation requirements for limited use public water
				  systems, multifamily water systems, and private water systems are included in
				  Chapter 64E-8, F.A.C.
(1) Well Casing,
				Liner Pipe, Coupling, and Well Screen Requirements.
(a) Well casing, liner pipe, coupling, and
				well screen shall be new or in like new condition. Such well casing, liner
				pipe, coupling, or well screen shall not be used unless free of breaks,
				corrosion and dents, is straight and true, and not out of round. Welded or
				seamless black or galvanized steel pipe or casing, or stainless steel pipe or
				casing, or approved types of nonmetallic pipe shall be used for well casing or
				liner pipe. All well casing shall conform to one of the following standards:
				American Society for Testing and Materials (ASTM) A53/A53M-99b (1999), A135-01
				(2001), A252-98 (1998), A589-96 (1996), or American Petroleum Institute (API)
				5L-2000 (2000). Well casing that conforms to any of the aforementioned ASTM or
				API standards shall also conform to the 2000 American National Standard
				Institute for Welded and Seamless Wrought Steel Pipe (ANSI/ASME B36.10M-2000).
				All well casing shall be stenciled with the applicable standard, or proper
				documentation of manufacturer specifications must be supplied to the permitting
				authority upon request. Copies of these standards may be obtained from the
				American Society for Testing and Materials, 100 Barr Harbor Drive, P. O. Box
				C700, West Conshohocken, PA 19428-2959; the American Petroleum Institute, 1220
				L Street NW, Washington, DC 20005-4070; and the American National Standards
				Institute, 1819 L Street NW, Washington, DC 20036, respectively.
(b) Black or galvanized steel casing
				installed by driving shall not have less than the dimensions and weights
				specified below.

Note: A 4 inch nominal size casing with a wall thickness of
				  .188 inches and a plain end weight of 8.66 pounds/foot may be used if it
				  conforms to standard API 5L-2000, Grade B, 60 KSI tensile strength. Other
				  casing that meets these minimum tensile strength standards shall be acceptable.
				  For example, A53/A53M-99b, Grade B, may also be substituted.
(c) Black or galvanized steel casing or liner
				pipe set into place without driving shall not have less than the dimensions and
				weights specified below.

(d)
				Stainless steel pipe used for casing or liner pipe shall be Schedule 10S of the
				American National Standards Institute (ANSI/ ASME B36.19M-1985), or stronger
				classification.
(e) Polyvinyl
				Chloride (PVC) pipe may be used for well casing, liner pipe, and well screens.
				Any PVC pipe used for well construction or repair shall at a minimum meet the
				specifications for Schedule 40 or Standard Dimension Ratio (SDR) 21. The
				appropriate water management district shall require the use of stronger PVC
				casing if necessary to protect the integrity of the well.
(f) The Department shall approve a well
				casing or liner pipe not otherwise specified in paragraphs
				 62-532.500(1)(a) through
				(e), F.A.C., if the applicant makes a
				showing, certified by a professional engineer, to justify that such use would
				provide an equivalent material strength and durability. The following material
				has been approved pursuant to this procedure: DNS Well-Cor, Allied Tube and
				Conduit, A Division of Grinnel Corporation, 1440 Massaro Boulevard, Tampa,
				Florida, 33619.

				Well casing, liner pipe, coupling, and well screens used for potable water well
				construction or repair shall conform to 2008 NSF International
				Standard/American National Standard NSF/ANSI 14-2008e, Plastics Piping System
				Components and Related Materials, or NSF International Standard/American
				National Standard NSF/ANSI 61-2008, Drinking Water System Components - Health
				Effects, both of which are adopted and incorporated by reference herein. Copies
				of these copyrighted standards may be obtained from NSF International, P. O.
				Box 130140, Ann Arbor, MI 48113-0140.
(h) 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 appropriate water management district
				which provide equivalent protection. PVC pipe shall be joined by solvent bonded
				couplings, threaded couplings, heat welding, or other methods approved by the
				appropriate water management district which provide equivalent
				protection.
(i) Nonmetallic and
				stainless steel well casing or liner pipe shall not be installed by driving
				unless prior approval is obtained from the appropriate water management
				district based on a demonstration that the integrity of the well casing or
				liner pipe will be maintained. 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 casing or pipe installed by driving unless
				prior approval is obtained from the appropriate water management district based
				on a demonstration that a drive shoe is not necessary to maintain the integrity
				of the casing or pipe.
