Underground petroleum storage tanks — See Ch. 112.
Water supply — See Ch. 189, Art II.
The purpose of this chapter is:
To protect the public potable water supply served by the Blackstone Water Department from the possibility of contamination or pollution by isolating such contaminates or pollutants which could backflow or backsiphon into the public water system.
To promote the elimination or control of existing cross-connections, actual or potential, between its customers in-plant potable water system and nonpotable systems.
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.
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.
Town of Blackstone Water Department Rules and Regulations adopted July 25, 1989.[1]
Editor's Note: Copies of the rules and regulations are available from the Water Department.
The Water Department shall be responsible for the protection of the public potable water distribution system from contamination or pollution due to the backflow or backsiphonage of contaminates or pollutants. If, as a result of a survey of the premises, the Blackstone Water Department 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 Blackstone Water Department, 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 Blackstone Water Department, 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.
As used in this chapter, the following terms shall have the meanings indicated:
The method of preventing backflow through the use of an unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture or other device and the flood level rim of the receptacle.
Accepted by the reviewing authority as meeting an applicable specification stated or cited in this regulation or as suitable for the proposed use.
A method to prevent backflow approved by the Department for use in Massachusetts.
An approved backflow device used to prevent backsiphonage which is not designed for use under static line pressure.
Any water supply of unknown or questionable quality on or available to the premises other than the supplier's approved public potable water supply.
The flow of water or other liquids, mixtures or substances into the distribution pipes of a potable water supply from any source other than the intended source.
A device having two independently operating check valves separated by an intermediate chamber with a means for automatically venting it to the atmosphere, in which the check valves are forced loaded to a normally open position.
Pressure created by mechanical means or other means which causes water or other liquids or substances to flow or move in a direction opposite to that which is intended.
A form of backflow due to reduced or subatmospheric pressure within a water system.
A loop of pipe rising at least 35 feet, at its topmost point, above the highest fixture it supplies.
The Town of Blackstone Water Department or owner or operator of a public water supply system.
Any physical, chemical, biological or radiological substance or matter in water.
Any actual or potential connection between a distribution pipe of potable water from a public water system and any waste pipe, soil pipe, sewer, drain or other unapproved source.

Any individual, corporation, company, association, trust, partnership, the commonwealth, a municipality, district, or other subdivision or instrumentality of the United States, except that nothing herein shall be constructed to refer to or to include any American Indian tribe or the United States Secretary of the Interior in his capacity as trustee of Indian lands.
An approved backflow prevention device designed to prevent only backsiphonage and which is designed for use under static line pressure and which has necessary appurtenances for testing.
An approved backflow prevention device incorporating two more check valves, an automatically operating differential relief valve located between the two checks, two shutoff valves and necessary appurtenances for testing.
An assembly of two spring-loaded, independently operating check valves without tightly closing shutoff valves and test cocks, generally employed immediately downstream of the water meter to act as a containment device.
The Department, its designee, or the local Plumbing Inspector, authorized by MGL c. 142 and licensed by the Board of State Examiners of Plumbers and Gas Fitters, whichever is responsible for the review and approval of the installation of an approved backflow prevention device.
The Blackstone Water Department will operate an active cross-connection control program to include the keeping of necessary records, which fulfills the requirements of the State Department of Environmental Protection's cross-connection regulations and is approved by the Department of Environmental Protection.
The owner shall allow his property to be inspected for possible cross-connections and shall follow the provisions of the Blackstone Water Department's program and the Department of Environmental Protection regulations.
Blackstone Water Department.
On new installations, the Blackstone Water Department 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.
For premises existing prior to the start of this program, the Blackstone Water Department 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.
The Blackstone Water Department 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.
If the Blackstone Water Department determines at any time that a serious threat to the public health exists, the water service will be terminated immediately.
The Blackstone Water Department shall have on its staff, or shall have a delegated representative who is, a backflow prevention device tester certified by the Commonwealth of Massachusetts.
The Blackstone Water Department 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 1991. Initial focus will be on high-hazard industries and commercial premises.
The owner shall be responsible for the elimination or protection of all cross-connections on his premises.
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.
The owner shall have any device that fails an inspection or test repaired by a licensed plumber.
The owner shall inform the Blackstone Water Department of any proposed or modified cross-connection and also any existing cross-connections of which the owner is aware but have not been found by the Blackstone Water Department.
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.
The owner shall install backflow preventers in a manner approved by the Department of Environmental Protection and by the Blackstone Water Department.
The owner shall install only reduced-pressure backflow preventers and double check valve assemblies approved by the State Department of Environmental Protection.
Any owner of industrial, commercial or institutional premises having a private well or other private water source must have a permit if the well or source is cross-connected to the Blackstone Water Department's system. Permission to cross-connect may be denied by the Blackstone Water Department. 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 Blackstone Water Department's system.
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.
The owner shall be responsible for the payment of all fees for permits, device testings, retestings in the case that the device fails to operate correctly and second reinspections for noncompliance with Blackstone Water Department or Department of Environmental Protection requirements.
The Blackstone Water Department recognizes the threat to the public water system arising from cross-connections. As such, the Blackstone Water Department, 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.
The Blackstone Water Department 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.
Any existing backflow preventer shall be allowed by the Blackstone Water Department to continue in service unless the degree of hazard is such as to supersede the effectiveness of the present backflow preventer or result in an 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.
