§ 27-901 General requirements. Plumbing and gas piping shall be
designed and installed so as to satisfy the following conditions and the
requirements of reference standard RS-16:
(a) All occupied premises shall have potable water. Every building
intended for human habitation, occupancy, or use shall be provided with
a supply of potable water.
(b) Sufficient water required. Plumbing fixtures, devices, and
appurtenances shall be supplied with water in sufficient volume and at
pressures adequate to enable them to function properly. The pipes
conveying the water shall be of sufficient size to provide the water
required without undue pressure reduction and without undue noise under
all normal conditions of use.
(c) Water conservation. Plumbing shall be designed and adjusted to use
the minimum quantity of water consistent with proper performance and
cleansing of the fixture of plumbing appurtenance.
(d) Safeguarding against explosion. Devices for heating and storing
water shall be designed, installed, and maintained to guard against
rupture of the containing vessel through overheating.
(e) Connection to public water supply systems and to sanitary or
combined sewer systems.
(1) GENERAL. a. The water distribution system and system for conveying
sewage from any building in which plumbing fixtures are installed shall
be connected, respectively, to a public water main and a sanitary or
combined sewer if either or both are available and, regarding the sewer,
if the department determines that connection thereto is feasible. The
department shall determine that connection is feasible if:
1. the sewer is of adequate capacity to receive all sewage flowing
from the building;
2. the sewer is in adequate physical condition to receive such sewage;
3. no physical obstacles exist, between the boundaries of the lot or
tract of land on which the building is located and the sewer, which
would make connection to the sewer impracticable;
4. the elevation of the sewer in relation to the lot or tract of land
on which the building is located is such that conveyance of the sewage
from the building to the sewer is not impracticable;
5. the sewer is located in the same drainage area as all or most of
the lot or tract of land on which the building is located; and
6. no other factor reasonably related to the conveyance of sewage from
the building to the sewer would make such connection impracticable or
undesirable as a proper means of sewage disposal.
b. Where a public water main is not available, an individual potable
water supply shall be provided, and where neither a sanitary nor a
combined sewer is available to which the department determines that
connection is feasible, a private sewer or private sewage disposal
system shall be provided. All such private systems shall be provided
subject to the approval of the commissioner and of any other agency or
agencies having jurisdiction, and constructed in accordance with the
requirements of reference standard RS-16 and, with respect to the
construction of individual on site private sewage disposal systems, in
accordance with the specifications and standards prescribed by the
commissioner, in consultation with the commissioner of environmental
protection, pursuant to section six hundred forty-three of the charter.
c. Extensions of public sewers and water mains shall be made in
accordance with the regulations of the department of environmental
protection.
(2) SYSTEMS AVAILABLE. a. A public water main, and a sanitary or
combined sewer for the purpose of conveying sewage, shall be deemed
available to a building in which plumbing fixtures are installed, except
to a one- or two-family dwelling, if a property line of such building is
within five hundred feet (measured along a street, alley, or
right-of-way) of the public water supply system or the sewer. The
connection shall be made in accordance with the applicable standards of
the department of environmental protection.
b. A public water supply system, and a sanitary or combined sewer for
the purpose of conveying sewage, shall be deemed available to a one- and
two-family dwelling if a property line of such dwelling is within one
hundred feet (measured along a street, alley, or right-of-way) of the
public water supply system or the sewer. The connection shall be made in
accordance with the applicable standards of the department of
environmental protection, provided, however, that such one- and
two-family dwelling need not connect directly to the sewer if the common
elements of an internal private drain are located in a dedicated,
unobstructed right-of-way that extends to the sewer with a minimum width
of ten feet located entirely outside of the building footprint and
outside of all overhangs and projections that are less than fourteen
feet in height above grade.
c. Where two or more one- or two-family dwellings are to be
constructed on a tract of land, or where a substantial improvement of
any other type of building or buildings is contemplated on a tract of
land, the public water supply system and/or the sanitary or combined
sewer may be declared available thereto by the agencies having
jurisdiction thereon even though the distances specified in
subparagraphs a and b of this paragraph are exceeded.
