[HISTORY: Adopted by the Water Commissioners of the Town of Middleton 1-11-2000.
Amendments noted where applicable.]
The purpose of these rules and regulations is to:
A.Â
Protect the public potable water supply served by the
Middleton Water Division from the possibility of contamination or pollution
by isolating such contaminants or pollutants which could backflow or backsiphon
into the public water supply system.
B.Â
Promote the elimination or control of existing cross-connections,
actual or potential, between the Middleton Water System and the customer's
nonpotable water system.
C.Â
Provide for the maintenance of a continuing program of
cross-connection control which will effectively prevent the contamination
or pollution of all potable water systems.
A.Â
As provided in the Federal Safe Drinking Water Act of

Regulations, 310 CMR 22.22, the public water supplier is responsible for the
safety of the public water system under its jurisdiction.
B.Â
As of January 1, 1999, the Town of Middleton shall, in
accordance with 310 CMR 22.22, have the authority to review and approve design
data sheets and plans and to determine what type of cross-connection prevention
device is required for each individual case. This approval is required of
all facilities being served by the public water supplier, including fire connections
as required under 310 CMR 22.22.
A.Â
Town responsibilities. The Middleton Water Division within
the Middleton Department of Public Works shall be responsible for the protection
of the public potable water distribution system from contamination or pollution
due to the backflow or backsiphonage of contaminants or pollutants. If, as
a result of a survey of the premises, the Middleton Water Division determines
that an approval backflow prevention device is required at the Town's water
service connection or as in-plant protection on any customer's premises, the
Middleton Water Division, or its delegated agent, shall issue a cross-connection
violation form directing said customer to install approved backflow prevention
devices. The customer shall, within a time frame determined by the Middleton
Water Division, install such approved device or devices at his own expense,
and failure or refusal or inability on the part of the customer to install
said device or devices within the specified time frame shall constitute a
ground for discontinuing water service to the premises until such device or
devices have been properly installed.
B.Â
Property owner's responsibilities. No persons shall maintain
upon premises which they own or occupy a cross-connection between the distribution
system of the Town's public water supply, the water of which is being used
for drinking, domestic, or culinary purposes, and the distribution system
of an unapproved water source, unless the installation has been reviewed and
approved in compliance with these regulations and appropriate permits have
been issued.

will provide on-site evaluations and/or inspections of plans in order to determine
the type of backflow preventer, if any, that will be required and notify the
owner of plan approval requirements by the appropriate reviewing authority.
(2)Â
For buildings existing prior to enactment of these rules
and regulations, the program coordinator will perform surveys of all industrial,
commercial, agricultural, municipal, and institutional facilities served by
the Water Division to determine if cross-connections exist and that all cross-connections
are properly protected by an appropriate device.
(3)Â

all necessary approvals and permits for the maintenance of cross-connections
and installation of backflow prevention devices and applying annually for
the renewal of each permit.
(4)Â
The owner shall have any device that fails an inspection
or test immediately repaired by a licensed plumber.
(5)Â
The owner shall inform the Water Division of any proposed
or modified cross-connection and also any existing cross-connection of which
the owner is aware but has not been found by the Superintendent of Public
Works or his designated agent.
(6)Â
The owner shall be responsible for spare parts, repair
tools, or a replacement device and the cost of any additional testing required
in excess of the semiannual test schedule for (RPBP) reduced-pressure backflow
preventers or the annual test required for all (DCVA) double check valve assemblies.
(7)Â

approved by the Town.
(9)Â
The owner will install only reduced-pressure backflow
preventers and double check valves assemblies approved by DEP.
(10)Â
Any owner of industrial, commercial, municipal, or institutional
premises having a private water source must have a local permit if the well
or source is cross-connected to the Town's water system. Permission to cross-connect
may be denied by the Superintendent of Public Works or his designee. The owner
may be required to install a backflow preventer at the service entrance if
a private water source is maintained even if it is not cross-connected to

the premises as necessary to allow inspection and testing of devices by the
Middleton Water Division or his designated agent.
(14)Â
The owner shall be responsible for having spare parts
and repair tools for the backflow devices on the premises at all times. If
the backflow device is not able to be repaired the owner is responsible for
supplying a replacement device.
(15)Â
No person, including a licensed plumber, will install
a cross-connection device on any facility served by the Water Division without
first receiving approval from the Water Division and filing a notice of approval
with the Water Division and the local plumbing inspector.
C.Â
Local plumbing inspector.
(1)Â
The local plumbing inspector, as authorized by MGL c.
143 and as required under 248 CMR 2.14(b), will ensure that potable water
supply systems are designed, installed, and maintained in a manner as to prevent
contamination from nonpotable sources which may be introduced to the Water
Division system through cross-connections.
(2)Â
After reviewing the plans and specifications for plumbing
work under 248 CMR 2.04(5) and before issuing a permit, the plumbing inspector,
as required by 248 CMR 2.14, shall require the installation of appropriate
devices as approved by DEP.
The Superintendent of Public Works recognizes the threat to the public
water system arising from cross-connections. As such, the Water Division,
whereas it is responsible for the quality of the public water supply, may
require cross-connection prevention devices on the water service entrance
to any customer who, as a result of unprotected cross-connections, could contaminate
the public water supply system. All associated costs would be the responsibility
of the owner.
Any existing backflow preventer device shall be allowed by the Water
Division to continue in service unless the degree of hazard is such as to
supersede the effectiveness of the present backflow preventer. Where the degree
of hazard has increased, as in the case of a residential installation converting
to a business establishment, a reduced-pressure backflow preventer must be
installed.
A.Â
The Superintendent of Public Works shall not allow a
cross-connection to exist with the public water supply system unless it is
considered necessary and all appropriate approvals and permits have been issued.
B.Â
Only the Superintendent of Public Works and the program
coordinator for the Town of Middleton can classify a violation found during
a survey.
C.Â
After any violations of the cross-connection regulations
are found, in surveys or otherwise, the Superintendent of Public Works must
sent out a cross-connection violation form detailing the violation(s) and
a procedure for corrective action. This shall include a requirement for plan
submittal and will indicate the deadline for such submittal. A period of 30
days will be granted for plan submittal unless a more appropriate schedule
is necessary in the judgment of the Superintendent of Public Works.
D.Â
If the owner of any premises does not initiate corrective
actions by the prescribed deadline, the Superintendent of Public Works will
then issue a follow-up letter indicating that the owner remains in violation
under 310 CMR 22.22, Section 2(b), of the Drinking Water Regulations of the
Commonwealth of Massachusetts. Failure to comply with this regulation will
result in the owner having his service terminated, unless corrective work
is initiated within 15 days and completed within 30 days.
E.Â
If the owner of any premises remains in noncompliance
after the deadline established in this second letter, the property will be
posted for shutoff and the Town of Danvers will be notified to terminate water
service. The owner will be notified through U.S. Postal Service certified
mail, return receipt requested.
F.Â
If circumstances arise where a large number of violations
are found and it becomes a large financial burden to the owner of the premises,
a creative enforcement strategy will be undertaken whereby corrective work
is staggered over a reasonable period of time. However, the public water supply
distribution mains must never be at risk, and containment devices will be
a priority at any high-hazard facility.
G.Â
If the occasion should arise where termination of the
water supply will result in unreasonable risk to the public health of the
community, then the DEP will be notified and other enforcement strategies
will be necessary, including but not limited to the assessment of an administrative
penalty to any owner in noncompliance with Section 22 of the Drinking Water
Regulations of the Commonwealth of Massachusetts.
H.Â
The termination of the water service to the owner's property
shall remain in effect until the owner has received an approval from the Town
of Middleton that the service no longer poses a threat to the public water
supply system.
I.Â
To verify if a threat still exists to the public water
supply system, an on-site inspection must be conducted, and testing of any
installed devices must be successfully completed. The owner will then be responsible
for requesting the inspection and/or test as well as providing any access
or plans requested by the program coordinator, including any fees associated
with on-site inspections or testing. In addition, the owner will also be responsible
to the Town of Danvers for any turnoff, turn-on, or other fees incurred as
a result of this violation.
J.Â
The Town will maintain a copy of all violation notices
and certified mail receipts. In addition, a summary listing of all violations
shall be established.
A.Â
All installations of reduced-pressure backflow preventers
(RPBP) which are registered by the Town of Middleton must be tested semiannually
by a Massachusetts DEP certified backflow tester. Any RPBP which is on line
less than six months of the year must be tested at least once. All installations
of double check valve assemblies (DCVA) which are registered by the Town must
be tested annually by a Massachusetts DEP certified backflow tester. Care
must be taken to ensure that these devices are protected against freezing,
flooding, and mechanical damage.
B.Â
Periodic testing shall be performed by a certified backflow
prevention device tester.
C.Â
The testing shall be conducted during the regular business
hours of the Department of Public Works. Testing after the regular hours,
when at the request of the owner, shall require additional charges to cover
the increased cost to the Town of Middleton.
D.Â
Any backflow preventer which fails during a periodic
test must be repaired or replaced by a licensed plumber. When repairs are
necessary, upon completion of the repair, the device will be retested at the
owner's expense to ensure proper operation. High-hazard situations will not
be allowed to continue unprotected if the backflow preventer fails the test
and cannot be repaired immediately. In other situations, a date of not more
than 14 days after the test date will be established. Parallel installation
of two devices is an effective means of ensuring that uninterrupted water
service remains during testing or repair of devices and is strongly recommended
when the owner desires such continuity.
E.Â
The Superintendent of Public Works reserves the right
to test RPBP and DCVA devices more frequently where there is a history of
test failures and the program coordinator, or his designee, feels that due
to the degree of hazard involved additional testing is warranted. Cost of
the additional tests will be borne by the owner.
B.Â
Reports. The Town of Middleton will submit the following
to the DEP:
C.Â
Availability of reports and records to the Town of Danvers.
The Town of Middleton Public Works Department will make available all records
and reports to the Town of Danvers Public Works Department since both Towns
share the same water system.
A.Â
Surveying. Surveying will begin on February 1, 1998,
starting with all municipal buildings followed by all other industrial, commercial,
and institutional facilities. Surveys will be complete by December 31, 1998.
B.Â
Inspection. Inspections of all new construction will
begin upon enactment of these rules and regulations and will continue on an
ongoing basis, as needed.
C.Â
Backflow device testing. Backflow device testing will
begin by January 1, 1999.
The fee structure shall be established by the Middleton Board of Selectmen
acting in their capacity as Middleton Water Commissioners and shall be attached.
