Backflow prevention devices are used to prevent the contamination
of the Salem Public Works Department, Water Division, system from
possible backflow of water or other contaminants into the system.
The Town of Salem follows the regulations set by the New Hampshire
Department of Environmental Services Administrative Order No. 2071,
as of July 1, 1982.
The purpose of this regulation is to identify and prevent the
contamination of the Salem water distribution system from possible
backflow of water or other liquids, gases, mixtures and process chemicals
into said system by action with its origin beyond the outlet of the
customer's water meter.
The Water Division will determine, as part of its granting of
a water service, those sites which will require a backflow prevention
device. There must be an approved backflow prevention device installed
and inspected by the Salem Water Division at those designated sites
prior to the water service being activated. This regulation will apply
to all municipal water customers with the level of hazard established
by the Salem Department of Public Works.
The Town of Salem acknowledges its responsibility to protect
the sanitary and aesthetic quality of its distribution system by enforcing
this article.
A. The Water Division will not permit any water connection to its system
that has the potential for backflow contamination without an approved
backflow prevention device. A permit will be supplied from this Department.
B. The Water Division will specify the location and type of device to
be installed in each location.
C. The Water Division will maintain records of these devices and will
perform a testing of the device as per this schedule:

There will be installed a proper, approved backflow prevention

Division. This installation is the customer's responsibility and will
be performed by competent plumbers, mechanical contractors, and those
licensed to provide plumbing services, under the direction of the
Water Division and/or the Building Division, as per the implementation
schedule:
A. Where water service must be continuous, an approved bypass will be
installed.
