  §  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.
  (f) Well water systems. No well or  individual  water  supply  may  be
installed  for  any purpose without the approval of the commissioner and
of the department of health and mental hygiene  and  the  department  of
environmental protection.
  (g)  Design  and  maintenance  of  system  for  conveying  sewage from
building.  The system for conveying sewage from the  building  shall  be
designed,  constructed  and maintained to guard against fouling, deposit
of solids, and clogging, and shall be provided with  adequate  cleanouts
so arranged that the pipes may be readily cleaned.
  (h) Exclusion of certain substances from the plumbing system.
  (1) DETRIMENTAL OR DANGEROUS MATERIAL. No person shall deposit, by any
means,  any of the following into the building drainage system or sewer:
ashes, cinders, rags, flammable, poisonous, or explosive liquids, gases,
