Every public garage or service station or other structure having
a water supply, either of a temporary or permanent character, used
for the housing, sale or repair of automobiles or in which automobiles
are washed, cleaned or repaired, shall be provided with a means of
drainage for the floors and repair pit in such a manner as will prevent

the roof, and it shall be provided with an air inlet open to the outer
air. The intercepting pit shall be of a design approved by the Plumbing
Inspector or other designated officer and shall be watertight, built

as to intercept all oils, gasoline or other fluids, as well as sand,
silt or other solids, for the purpose of excluding the same as from
the sewer system. It shall be provided with one or more twenty-four-inch
cast-iron manholes and covers, which shall be so located as to be
easily accessible for cleaning.
