The purpose of this article is as follows:
A. To protect the public water supply from contamination or pollution
by isolating, within the property owner's water system, contaminates
or pollutants which could backflow through the service connection
into the public water system.
B. To promote the elimination or control of existing cross-connections,
actual or potential, between public and outside water supplies and
nonpotable water system, plumbing fixtures and sources or systems
containing process fluids.
C. To provide for the maintenance and continuation of a cross-connection
and backflow control program which will prevent the contamination
or pollution of the public water supply.
The type of protection required under §
170-23A,
B and
C of this article shall depend on the degree of hazard which exists, as follows:
A. An approved air gap separation shall be installed where the public
water supply system may be contaminated with substances that are dangerous
to public health and could cause a severe health hazard and where
such a device would be technically feasible and or practical.
B. An approved air gap separation or an approved reduced pressure zone
device shall be installed where the public water supply system may
be contaminated with a substance that could cause a system or health
hazard.
C. An approved air gap separation, an approved reduced pressure zone
device, or an approved double-check valve assembly shall be installed
where the public water supply system may be polluted with substances
that would be objectionable but not dangerous to health.
All geothermal heating and cooling systems must remain physically
disconnected (no cross-connections allowed) from public and private
water systems.
Only authorized persons shall be permitted to use fire hydrants.
Tampering with the hydrants by unauthorized persons is prohibited.
Any person wishing to use a fire hydrant other than the Doylestown
Township Municipal Authority or other provider of public water or
fire company must obtain a permit from the Doylestown Township Municipal
Authority or other provider of public water. No cross-connection in
the use of a fire hydrant is permitted.
