Ohio Administrative Code › Title 3701 - Department of Health - Administration and Director › Chapter 3701-28 - Private Water Systems › Section 3701-28-12 - Construction and surface design of cisterns, reservoir tanks, hauled water storage tanks, and roof washers

Current through all regulations passed and filed through July 1, 2024
(A)
								Cisterns,
			 reservoir tanks, and hauled water storage tanks shall be watertight with a
			 reasonably smooth, clean interior surface. All concrete tanks shall be made of
			 materials and constructed in accordance with ASTM specifications C 913-2016.
			 All plastic or fiberglass tank materials shall meet NSF standard 61-2016. All
			 joints, connections, and other seams between component parts shall be sealed
			 with nontoxic waterproof material that meets NSF standard 61-2016 or equivalent
			 to prevent the loss of stored water and the infiltration of surface or ground
			 water.
(B)
								Cisterns, reservoir tanks, and hauled water storage
			 tanks shall be easily accessible for cleaning. Partitions, baffles, or similar
			 structural features shall be constructed of nonabsorbent, easily cleanable
			 materials, free of spalls, cracks, or crevices which may entrap unwanted
			 matter.
(C)
								The capacity of cisterns and hauled water storage tanks
			 shall be adequate to meet the intended needs of the household. No new cistern
			 of less than two thousand five hundred gallons capacity per dwelling unit shall
			 be installed. No new hauled water storage tank of less than one thousand
			 gallons capacity per dwelling unit shall be installed, except if the tank is a
			 supplemental water reservoir tanks for wells, ponds, and springs designed to
			 receive hauled water as an additional water source.
(D)
								Inlets to
			 cisterns and hauled water storage tanks shall be of sufficient size and design
			 to dissipate the pressure of the influent stream and minimize the stirring of
			 any settled solids.
(E)
								Cisterns, reservoir tanks, and hauled water storage
			 tanks shall be set level and at an adequate depth or location to prevent frost
			 heave. The bottom of the excavation shall be continuous, relatively smooth, and
			 free of rocks. The bottom of the excavation shall have a minimum of four inches
			 of material approved by the manufacturer of the tank. Tanks shall not bear on
			 rock ledges. Backfill shall be free of any large stones or debris, and shall be
			 placed in a manner consistent with tank manufacturer recommendations. Earth
			 cover shall be graded to prevent water from standing over the cistern or hauled
			 water storage tank.
(F)
								Manholes or risers shall be sealed to the top of the
			 cistern or hauled water storage tank:
(1)
									Concrete tanks
			 shall have an opening of a minimum diameter of twenty-four inches and shall be
			 constructed of the same or compatible material as the cistern or hauled water
			 storage tank.
(2)
									Plastic tanks shall have an opening of a minimum
			 diameter of eighteen inches.
(3)
									The manhole
			 opening shall have a watertight cover with edges projecting a minimum of eight
			 inches above the level of the surrounding surface. The edges of the manhole or
			 riser cover shall overlap the curb and project downward a minimum of two
			 inches. The covers shall be secured to minimize the danger of contamination,
			 accidents, and unwarranted entry.
(4)
									A concrete patio
			 or wood deck may be located over a cistern or hauled water storage tank
			 provided that proper access is maintained for filling, service and
			 inspections.
