[Ord. No. 11-0248 §1, 8-9-2011]
A. Approval. All tanks shall be of an approved type. The design of tanks shall conform to the requirements in Section
705.350 Sewage Tanks. All tanks shall be designed to withstand the pressures to which they are subjected.
B. Precast Concrete Tanks. Precast concrete tanks shall conform
to ASTM C 913. The floor and sidewalls of a site-constructed concrete
tank shall be monolithic, except a construction joint will be permitted
in the lower twelve (12) inches of the sidewall of the tank. The construction
joint shall have a keyway in the lower section of the joint. The width
of the keyway shall be approximately thirty percent (30%) of the thickness
of the sidewall with a depth equal to the width. A continuous water
stop or baffle at least fifty-six (56) inches wide shall be set vertically
in the joint, embedded one-half (½) its width in the concrete
below the joint with the remaining width in the concrete above the
joint. The water stop or baffle shall be copper, neoprene, rubber
or polyvinyl chloride designed for this specific purpose. Joints between
the concrete tank and the tank cover and between the tank cover and
manhole riser shall be tongue and groove or shiplap-type and sealed
water-tight.
1. The concrete tank and tank lid shall be reinforced by using a minimum
reinforcing of six (6) inch by six (6) inch Number 10 gauge welded
steel reinforcing wire in the top, bottom ends, and sides of the tank.
The reinforcing wire shall be lapped at least six (6) inches. Concrete
cover shall be required for all reinforcement. Reinforcement shall
be placed to maximize the structural integrity of the tank. The tank,
tank lid, riser and riser cover shall be able to withstand a uniform
live loading of one hundred fifty (150) pounds per square foot in
addition to all loads to which an underground tank, riser or riser
cover is normally subjected, such as the dead weight of the concrete
and soil cover, active soil pressure on tank walls, and the uplifting
force of the ground water. Additional reinforcement shall be required
when the loads on a concrete tank, riser or riser cover are exceeded
by subjecting it to vehicular traffic or when the top of the tank
is placed deeper than three (3) feet below the finished grade.
2. The top, bottom, ends and sides of the tank must have a minimum thickness
of two and one-half (2½) inches.
3. A minimum twenty-eight (28) day concrete compressive strength of
thirty-five hundred (3,500) pounds per square inch shall be used in
the construction of the septic tank, concrete access riser and riser
cover. The concrete shall achieve a minimum compressive strength of
three thousand (3,000) pounds per square inch prior to removal of
the tank from the place of manufacture. It shall be the responsibility
of the manufacturer to certify that this condition has been met prior
to shipment.
4. After curing, tanks manufactured as required, concrete risers shall
be joined and sealed at the joint by using a mastic, butyl rubber,
or other pliable sealant that is water-proof, corrosion-resistant,
and approved for use in septic tanks. The sealant shall have a minimum
size of one (1) inch nominal diameter or equivalent. Before sealing,
the joint shall be smooth, intact and free of all deleterious substances.
C. Manholes. Manhole collars and extensions shall be of the
same material as the tank. Manhole covers shall be of concrete, steel,
cast iron or other approved material.
D. Fiberglass Tank. Fiberglass reinforced plastic tanks shall
be constructed with materials capable of resisting corrosion from
sewage and sewage gases, and the active and passive loads on the unit
walls.
1. Fiberglass tanks shall have the following minimum physical properties:
a. Ultimate tensile strength: 12,000
b. Flexural strength: 19,000
c. Flexural modulus of elasticity: 200,000
2. A vacuum test shall be performed on a least one (1) fiberglass tank
of each model number by an independent testing laboratory, in accordance
with ASTM D-4021, Standard Specification for Glass- Fiber Reinforced
Polyester Underground Petroleum Storage Tanks, which is hereby incorporated
by reference including any subsequent amendments and editions. Units
must withstand negative pressure of two and one-half (2½) pounds
per square inch (sixty-nine and three-tenths (69.3) inches of water)
without leakage or failure. Test results shall be included with the
specifications that are provided to the State for approval.
3. Composition of the finished unit shall be at least thirty percent
(30%) reinforcement by weight. Minimum wall thickness shall be one-fourth
(¼) inch. However, a wall thickness of not less than three-sixteenth
(3/16) inch may be allowed in small, isolated areas of the fiberglass
tank.
4. Interior and exterior surfaces shall have no exposed fibers or projections,
no blisters larger than one-fourth (¼) inch in diameter, and
no pores or indentations deeper than one-sixteenth (1/16) inch. The
tank shall be water-tight.
5. Prefabricated tanks other than precast reinforced concrete or fiberglass
reinforced plastic units shall be approved by the Code Commission
on an individual basis based on information furnished by the designer
that indicates the unit will provide effectiveness equivalent to reinforced
concrete or fiberglass reinforced plastic units.
6. Fiberglass tanks shall bear an imprint identifying the manufacturer,
serial number and the liquid or working capacity of the unit. The
imprint shall be located to the right of the blockout or opening made
for the outlet pipe on the outside of the unit. Fiberglass tanks shall
also be permanently marked with the date of manufacture adjacent to
the unit imprint or on the top of the unit directly above the imprint.
