N.Y. Comp. Codes R. & Regs. Tit. 10 § 7-1.9 - Water supply
(a) The
water supply serving all plumbing fixtures, including drinking fountains,
lavatories and showers, shall, after treatment, meet the provisions required
for a public water system as defined in subpart 5-1 of the State Sanitary Code.
A temporary residence with an on-site water supply that does not meet the
definition of a public water system must comply with the standards established
in subpart 5-1 for a non-community water system.
(b) Annual start-up. The temporary residence
operator must ensure that the following actions have been taken at least 15
days prior to the property's occupancy for which the water supply is utilized
each year. The following applies to each on-site potable water system that is
not subject to continuous water use, and to each temporary residence potable
water supply distribution system which receives water from an off-site public
water system and is not subject to continuous water use.
(1) All water mains shall be disinfected by:
(i) completely filling the main to remove all
air pockets, flushing the main to remove particulates, and filling the main
with potable water. The potable water shall then be chlorinated by feeding
liquid hypochlorite at a constant rate such that the water will not have less
than a 25 mg/l free chlorine residual throughout the temporary residence water
system. After a 24-hour holding period there must be a free chlorine residual
of not less than 10 mg/l throughout the temporary residence water system;
or
(ii) using a disinfection method
the State Commissioner of Health has determined in writing to be as protective
as the disinfection procedure described in subparagraph (i) of this
paragraph.
(2) The water
system shall then be flushed and free chlorine residual disinfection
concentrations measured at representative points in the distribution system to
ensure that no free chlorine is present if a waiver of disinfection has been
issued, or that a free chlorine residual of greater than 0.2 mg/l and less than
4.0 mg/l is present in a system with continuous disinfection.
(3) Bacteriological samples shall then be
collected from each water source at representative points in the distribution
system and analyzed at a laboratory certified by New York State Department of
Health.
(4) The facility operator
must report sample results, if positive for total coliform or escherichia coli
to the permit-issuing official as soon as possible but no later than 24 hours
of being notified by the laboratory. Pre-operational water analysis reports
must be submitted to the permit-issuing official prior to permit issuance. All
other water analysis reports required to be made by this Subpart or requested
or ordered by the permit-issuing official shall be submitted to the
permit-issuing official within 10 days of the end of each quarter in which
samples were collected.
(c) Water distribution and treatment.
Facilities shall be provided and maintained for the satisfactory treatment and
distribution of water. In addition, such facilities shall meet the following
requirement:
(1) Submission of plans; prior
approval. A plan for a new or modified water source, or distribution and
treatment facilities shall be submitted to the permit-issuing official at least
60 days prior to construction. No construction of new or modified water
distribution and/or treatment facilities shall commence until plans and
specifications have been submitted to and approved by the permit-issuing
official. Construction shall be in accordance with the approved
plans.
(d) Minimum
standards. Potable hot or tempered and cold running water shall be adequate in
quantity and quality and shall be readily available to occupants of the
temporary residence. Only potable water shall be easily accessible. Any
non-potable water supply shall be conspicuously labeled as a non-potable
supply. An adequate supply shall mean a minimum of 50 gallons per person per
day or more dependant upon amenities provided at the facility, unless otherwise
justified in writing by a professional engineer or registered architect
licensed to practice in New York State and deemed acceptable by the
permit-issuing official.
(e)
Connections prohibited. There shall be no physical connection between the
potable water supply and any non-potable water supply. Any fixture,
installation or equipment, which is subject to back-siphonage, shall be
adequately installed and maintained to protect against contamination of the
water system.
(f) A minimum
pressure of 20 pounds per square inch, at peak demand, shall be maintained in
all parts of the water distribution system.
(g) A common drinking utensil shall not be
provided for individual consumption of potable water.
(h) Interruptions, changes in sources or
treatments. Any incident or condition, which affects the quantity or quality of
the on-site potable water supply, shall be reported to the permit-issuing
official within 24 hours of occurrence. There shall be no changes made to the
source or method of treatment of a potable water supply, either temporary or
permanent, without first receiving approval from the permit-issuing official.
An adequate supply of potable water must be provided and maintained during all
times of operation.
