Fla. Admin. Code Ann. R. 40A-3.507 - Casing and Liner Pipe Standards

(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.

14-30		0.375 (standard wall, Schedule 40)
Greater than 30		0.500 (standard wall, Schedule 40)

Note: A 4 inch nominal size casing with a wall thickness of 0.188 and a plain end weight of 8.66 may be used if it conforms to standard API 5L-6/91, Grade B, 60 KSI tensile strength. For example A53-89A, Grade B, may also be substituted.

(4) Black or galvanized steel casing or liner pipe set into place without driving shall not have less than the dimensions and weights specified in Table 2.

8	8.625	0.188	16.94
10-16		0.250
Greater than 16		0.375

(5) 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.
