The purpose of these regulations is to safeguard the Village of Nassau's
potable water supply by preventing backflow of hazardous and nonpotable material
into the public water system through service connections. It is the intent
of this chapter to recognize that there are varying degrees of hazard and
to apply the principle that the degree of protection should be commensurate
with the degree of hazard.
As used in this chapter, the following terms shall have the meanings
indicated:
APPROVED PROTECTION DEVICE
A backflow prevention device that has been approved by the New York
State Health Department, including double check valve assemblies, reduced
pressure zone devices, and air gaps.
AUXILIARY WATER SOURCE
Any water source on or available to the premises other than the Village
of Nassau's public water system.
BUILDING INSPECTOR
The employee of the Village of Nassau in charge of overseeing building
inspections and code compliance.
CERTIFIED WATER OPERATOR
The employees of the Village of Nassau overseeing the day-to-day
operations of the Water Department, who are New York State certified water
operators.
CROSS CONNECTION
Any connection between any part of the Village of Nassau's public
water system and any source or system containing water or a substance that
is not approved as equally safe, wholesome, and potable for human consumption.
PUBLIC WATER SYSTEM
The water mains, pipes, pumping stations, and storage facilities
owned and operated by the Village of Nassau.
WATER SUPERINTENDENT
The Superintendent of Water as designated by the Village Board of
the Village of Nassau, or his/her designated representative.
Where the potential cross-connection is limited to a single fixture
in one building on the premises, the Water Commissioner may, after consultation
with the water operator, allow the approved protection device to be installed
on the piping to that particular fixture rather than the service entrance
pipe.
In determining where an approved protection device shall be required,
and the appropriate type of device, the water operator shall use the most
current guidance material provided by the New York State Health Department.
A water customer required to install an approved protection device shall
submit plans and specifications for such installations to the Building Inspector,
who must approve the plans prior to installation. In the event the device
to be installed is a reduced pressure zone device, the plan must be prepared
by a New York State licensed professional engineer or registered architect,
and must conform to the guidelines of the New York State Health Department.
The Building Inspector may refer the plans to the Rensselaer County Health
Department for review and approval.
This chapter shall take effect on January 1, 2007. Compliance for existing
customers shall occur on or before June 30, 2007.
