Section 445A.66915 - Water wells: Slabs and pedestals; construction with lineshaft turbine pump or submersible pump1. A water well with an above-ground discharge must be protected by a concrete slab and, if the well is equipped with a lineshaft turbine pump, with a concrete pedestal, both of which are constructed of continuously poured concrete. The pedestal must be of a sufficient diameter to extend at least 3 inches beyond the outer periphery of the sanitary seal. The slab must:(a) Be placed above the finished grade;(b) Have a minimum thickness of 6 inches;(c) Slope away from the pedestal at a minimum slope of 2 percent;(d) Extend a minimum of 4 feet from the casing of the well in all directions; and(e) Be free from cracks and other defects likely to detract from its capability to remain watertight. The casing of the well must extend to a height of at least 12 inches above the slab and at least 18 inches above the level of the final ground surface or 100-year floodplain, whichever is greater.
2. If a water well is equipped with a lineshaft turbine pump:(a) The top of the casing must be sealed into the base of the pump or the casing must be inserted into a recess extending at least 1 inch into the base of the pump.(b) The foundation and base of the pump must be designed in such a manner as to prevent water from coming into contact with joints between the base of the pump and the casing, and from entering the well.3. Any submersible pumps installed in a water well must be constructed in accordance with American Water Works Association Standard E102, as adopted by reference in NAC 445A.6663.Nev. Admin. Code § 445A.66915
