[Amended 10-19-1993 by L.L. No. 8-1993]
A. Any multiple dwellings constructed on or after March
1, 2000, and any existing multiple dwellings where there is an alteration
of the existing drainage system beyond 50% of the replacement value,
built to accommodate or accommodating four families or more shall
have an eight-inch sewer which shall connect with the public sewer
service or with a private sewer which shall in turn connect with the
public sewer. At the point of connection between the house sewer and
such private or public sewer, a manhole shall be constructed by a
licensed plumber at the expense of the owner and without cost to the
Village. Such manhole shall be constructed in accordance with specifications
and requirements of the Superintendent of Public Works Department.
[Amended 4-18-2000 by L.L. No. 4-2000]
B. Any property other than a one- or two-family dwelling
in which there is generated solid or viscous substances which may
cause an obstruction to the flow in a sewer or other interference
with the proper flow of waste, such waste water shall flow through
an approved exterior independent grease interceptor of a minimum one-thousand-gallon-capacity
tank or larger as determined by the Building Department. Such interceptor
shall be constructed of a six-inch monolithic poured reinforced concrete
tank with two removable twenty-four-inch cast-iron covers set in an
eight-inch concrete slab and installed at grade level. Where the Building
Department has determined that there is insufficient space to install
an exterior grease interceptor, a one-thousand-gallon fabricated,
three-sixteenths-inch gauge steel grease interceptor or a one-thousand-gallon
concrete grease interceptor as described in this section shall be
installed in the interior of the same building where the waste is
generated.
[Amended 7-5-1994 by L.L. No. 4-1994; 9-2-1998 by L.L. No. 8-1998]
C. A plot plan shall accompany the application for the
plumbing permit indicating the drain piping from the interceptor to
the building sanitary drain and the location of the interceptor on
the premises.
D. Interceptors shall be cleaned and pumped out as necessary.
A record shall be kept on the premises showing the date when cleaned
and pumped out. All effluent shall be removed from the premises by
a private contractor being duly licensed by the Nassau County Department
of Consumer Affairs.
E. If any interceptor tank is abandoned, unused, leaking
or defective, and the Village of Hempstead so requires, the tank and
piping shall be immediately removed from the premises and replaced
by a licensed plumber at the expense of the owner and without cost
to the Village.
F. Notwithstanding the above, the use of interceptors
shall comply with the provisions of the Nassau County Sewer Ordinance
and the New York State Uniform Fire Prevention and Building Code.
Every building shall be provided with proper
metallic gutters and rain leaders for conducting water from all roofs
in a manner that shall protect the walls and foundation from damage.
In no case shall the water from any rain leader be allowed to flow
upon the sidewalk or adjoining property, but the water from said leaders
may be conducted by proper pipes laid below the surface of the sidewalk
to the street gutter or may be conducted by cast-iron pipe to a leaching
cesspool located at least 15 feet from any building. No plumbing fixtures
shall discharge into a leaching cesspool. Any series or group of leaders
entering into one cesspool or dry well shall be trapped. Traps for
area, floor or other drains shall be at least three inches in diameter.
Discharge into a sewer is prohibited. Wherever pipes are laid beneath
a sidewalk pursuant to this section, such work shall be done in accordance
with the requirements of the Superintendent of the Engineering Department,
and the sidewalk shall be restored to the same condition as before
said work was done. The Superintendent of the Engineering Department
may refuse to permit pipes to be placed under the sidewalks as provided
in this section when storm sewers are available.
