§ 33-1 Purpose.

The purpose of this bylaw shall be:
A. 
To protect the public potable water supply served by the Barre Water Commission from the possibility of contamination of pollution by isolating such contaminants or pollutants which could backflow or backsiphon into the public water system.
B. 
To promote the elimination or control of existing cross-connections, actual or potential, between its customers in-plant potable water system and nonpotable systems.
C. 
To 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 by cross-connection.

§ 33-2 Responsibility of Water Purveyor; rules and regulations.

A. 
As provided in the Federal Safe Drinking Water Act of 1974 (Public Law 93-523), and the Commonwealth of Massachusetts Drinking Water Regulations, 310 CMR 22.22, the Water Purveyor has the primary responsibility for preventing water from unapproved sources or any other substances from entering the public potable water system.
B. 
Barre Water Commission Rules and Regulations are hereby adopted.

§ 33-3 Installation of backflow prevention device by owner; discontinuance of water service for failure to comply.

The Water Commission 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 Commission determines that an approved backflow prevention device is required at the town's water service connection or as in-plant protection on any customer's premises, the Commission, or its delegated agent, shall issue a cross-connection violation form to said customer to install approved backflow prevention devices. The customer shall, within a time frame determined by the Commission, 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.

§ 33-5 Compliance with program and regulations.

A. 
The Commission will operate an active cross-connection control program, to include the keeping of necessary records, which fulfills the requirements of the State DEP's Cross-Connection Regulations and is approved by the Department.
B. 
The owner shall allow his property to be inspected for possible cross-connections and shall follow the provisions of the Commission's program and the Department regulations.

§ 33-6 Responsibilities of Commission and owners.

A. 
Commission.
(1) 
On new installations the Commission will provide on-site evaluation and/or inspection 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) 
For premises existing prior to the start of this program, the Commission will perform surveys of the premises and reviews of as-built plans and issue a cross-connection violation form to the owner detailing any corrective action required, the method of achieving the correction, and the time allowed for the correction to be made. The time period allowed shall depend upon the degree of hazard involved.
(3) 
The Commission will not allow any cross-connection to remain unless it is protected by an approved backflow preventer for which a permit has been issued and which will be regularly tested to ensure satisfactory operation.
(4) 
If the Commission determines at any time that a serious threat to the public health exists, the water service will be terminated immediately.
(5) 
The Commission shall have on its staff, or shall have a delegated representative, who is a backflow prevention device tester certified by the Commonwealth of Massachusetts.
(6) 
The Commission will begin initial premises inspections to determine the nature of existing or potential hazards, following the approval of this program by the Department, during calendar year 1996. Initial focus will be on high-hazard industries and commercial premises.
B. 
Owner.
(1) 
The owner shall be responsible for the elimination or protection of all cross-connections on his premises.
(2) 
The owner shall be responsible for applying for and obtaining 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.
(3) 
The owner shall have any device that fails an inspection or test repaired by a licensed plumber.
(4) 
The owner shall inform the Commission of any proposed or modified cross-connection and also any existing cross-connections of which the owner is aware but has not been found by the Commission.
(5) 
The owner shall not install a bypass around any backflow preventer unless there is a backflow preventer of the same type on the bypass. Owners who cannot shut down operation for testing of the device(s) must supply additional devices necessary to allow testing to take place.
(6) 
The owner shall install backflow preventers in a manner approved by the Department and by the Commission.
(7) 
The owner shall install only reduced-pressure backflow preventers and double check valve assemblies approved by the Department.
(8) 
The owner of any residential premises having a private well or other private water source will not be allowed a physical connection with the public water supply system.
(9) 
The owner shall be responsible for the payment of all fees for permits, device testings, retesting in the case that the device fails to operate correctly, and second reinspections for noncompliance with Commission or Department requirements.

§ 33-7 Containment devices for unprotected cross-connections.

The Commission recognizes the threat to the public water system arising from cross-connections. As such, the Commission, whereas it is responsible for the quality of the public water supply, may require a containment device on the water service entrance to any customer who, as a result of unprotected cross-connections, could contaminate the public water supply system.

§ 33-8 Increase in degree of hazard.

Any existing backflow preventer shall be allowed by the Commission to continue in service unless the degree of hazard is such as to supersede the effectiveness of the present backflow preventer or results in a unreasonable risk to the public health. Where the degree of hazard has increased, as in the case of a residential installation converting to a business establishment, any existing backflow preventer must be upgraded to a reduced-pressure backflow preventer, or a reduced-pressure backflow preventer must be installed in the event that no backflow device was present.

§ 33-9 Periodic testing.

A. 
Reduced-pressure backflow preventers and double check valve assemblies shall be tested and inspected at least semiannually by the Commission.
B. 
Periodic testing shall be performed by the Commission's certified tester or his delegated representative, who shall be a certified tester.
C. 
The testing shall be conducted during the Commission's regular business hours. Exceptions to this, when at the request of the owner, may require additional charges to cover the increased costs to the Commission.
D. 
Reduced-pressure backflow preventers and double check valve assemblies must be tested annually by the owner independent of the semiannual test by the water supplier, and said test must be conducted by a certified tester.
E. 
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 compliance date of not more than 14 days after the test date will be established. The owner is responsible for spare parts, repair tools or a replacement device. Parallel installation of two devices is an effective means of the owner ensuring that uninterrupted water service remains during testing or repair of devices and is strongly recommended when the owner desires such continuity.
F. 
Backflow prevention devices will be tested more frequently than specified above in Subsection A in cases where there is a history of test failures and the Commission feels that, due to the degree of hazard involved, additional testing is warranted. Cost of the additional tests will be born by the owner.

§ 33-10 Records and reports.

A. 
Records. The Commission will initiate and maintain the following:
(1) 
Master files on customer cross-connection tests and/or inspections.
(2) 
Master files on approved cross-connection installations.
(3) 
Copies of lists and summaries supplied to the Massachusetts Department of Environmental Protection.
