Universal Citation: UT Admin Code R 317-4-8
Current through Bulletin 2024-06, March 15, 2024
(1) The regulatory authority shall inspect the entire installation before backfilling to determine compliance with this rule. Some components or system types require additional testing or inspection methods as outlined in the following.
(a) Each tank shall be tested for water
tightness before backfilling.
(i) Each tank
shall be filled 24 hours before the inspection to allow stabilization of the
water level. Considering water absorption by the concrete, there may not be a
change in the water level nor any water moving visibly into or out of the tank.
Testing shall be supervised by the regulatory authority. Tanks exhibiting
obvious defects or leaks may not be approved unless such deficiencies are
repaired to the satisfaction of the regulatory authority.
(A) The regulatory authority may allow two
piece tanks, with the joint below the water level, to be backfilled up to 3
inches below the joint to provide adequate support to the seam of the
tank.
(B) Any polyethylene or
fiberglass tank may be backfilled as per manufacturers'
recommendations.
(ii) If
ground water elevations inhibit the ability to visibly inspect the exterior of
the tank, the tank may be tested by its ability to exclude
water.
(b) Each
distribution or drop box should be installed level and the flow distribution
lines shall be checked by filling the box with water up to the
outlets.
(c) Any pump, controls, or
alarms shall have its correct operation verified.
(d) Any deep wall trench or seepage pit shall
have the depth of the trench excavation verified.
(e) For each at-grade or mound system:
(i) the preparation of the original ground
before the placement of fill shall be verified; and
(ii) the final cover shall meet
requirements.
(f) For
each alternative or experimental system, additional inspections shall be
dictated by the complexity of the system and absorption system type as
identified by the regulatory authority.
(g) Final approval shall be issued by the
regulatory authority before operation of any system, and shall include an
as-built drawing of the completed system.
