The purpose of this regulation is as follows:
A. 
To protect the public potable water supply of the city of Revere from the possibility of contamination or pollution by isolating within the customer's internal distribution system(s) or the customer's private water system(s) such contaminants or pollutants which could flow into the public potable water supply; and
B. 
To promote the elimination or control of existing cross connections between the customer's in-plant potable water system(s) and nonpotable water system(s), plumbing fixtures and industrial piping systems; and
C. 
To provide for the maintenance of a continuing cross connection control program which will systematically and effectively prevent contamination or pollution of all potable water systems.
(C.O. 07-23 § 1 (part))
The city of Revere plumbing department (hereinafter called the "city") shall be responsible for the protection of the public drinking water supply from contamination or pollution due to the backflow of contaminants or pollutants through the water service connection. If, in the judgment of the city, an approved backflow prevention assembly is required at the customer's private water system, for the safety of Revere's public water supply, the city shall give notice in writing to said customer to install an approved backflow prevention device(s) at specific location(s) on the customer's premises. The customer shall immediately install such approved devices, at the customer's expense. The failure, refusal or inability on the part of the customer to install, have tested and maintain said devices shall constitute grounds for the disconnection of water service to the premises until such requirements have been satisfactorily met.
(C.O. 07-23 § 1 (part))
As used in this section, unless the context indicates otherwise, the following words shall have the following meanings:
"Air gap separation"
means 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 of the receptacle.
"Approved backflow prevention device" or "device"
means a method to prevent backflow approved by the Massachusetts Department of Environmental Protection for use in Massachusetts.
"Atmospheric vacuum breaker"
means an approved backflow device used to prevent back siphonage which is not designed for use under static pressure.
"Backflow preventer with intermediate atmospheric vent"
means 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 force-loaded to a normally closed position and the venting means is force-loaded to a normally open position.
"Backflow"
means 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.
"Barometric loop"
means a loop of pipe rising at least thirty-five feet, at its topmost point, above the highest fixture it supplies.
"Contaminant"
means any physical, chemical, biological or radiological substance or matter in water.
"Cross connection"
means any 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. Without limiting the generality of the foregoing, the term "cross connection" shall also include any bypass arrangements, jumper connections, removal section swivel or changeover connection and other temporary or permanent connection through which backflow can or may occur.
"Double check valve assembly"
means a backflow prevention device which incorporates an assembly of check valves, with shutoff values at each end and appurtenances for testing.
"Potable water"
means water from any source which has been approved by the department of environmental protection for human consumption.
"Pressure vacuum breaker"
means an approved backflow prevention device designed to prevent only back siphonage and which is designed for use under static line pressure.
"Public water supply system"
means a system for the provision to the public of piped water for human consumption as defined in 310 CMR 22.02(8).
"Reduced pressurer backflow preventer"
means an approved backflow prevention device incorporating (1) two or more check valves; (2) automatically operating differential relief value located between the two checks; (3) two shutoff valves; and (4) necessary appurtenances for testing; and which is designed to operate so that (5) the pressure in the zone between the two check valves is maintained at a value less than the pressure on the public water system side of the device; and (6) at cessation of normal flow, the pressure in the zone between the two check valves is maintained at a value less than the pressure on the public water system side of the device; and (7) in the case of leakage of either check valve, the differential relief valve shall operate to maintain reduced pressure in the zone by discharging to the atmosphere.
(C.O. 07-23 § 1 (part))
The water system shall be considered as made up of two parts: the utility system and the customer system.
A. 
The utility system shall consist of source facilities and the distribution system, and shall include all those facilities of the water system under the complete control of the utility, up to the point where the customer's system begins. In this definition, the "source" shall include all components of the facilities utilized in the production, treatment, storage and delivery of water to the distribution system; and the "distribution system" shall include the network of conduits used for the delivery of water from the source to the customer's system.
B. 
The customer system shall include those parts of the facilities beyond the termination of the utility distribution system which are utilized in conveying utility delivered domestic water to points of use.
(C.O. 07-23 § 1 (part))
A. 
No water service connection to any premises shall be installed or maintained by the water purveyor unless the water supply is protected as required by Massachusetts state laws and regulations and this chapter. Service of water to any premises shall be discontinued by the city if a backflow prevention assembly required by this chapter and Massachusetts law is not installed, tested and maintained, or if it found that a backflow prevention assembly has been removed, bypassed or if an unprotected cross connection exists on the premises. Service will not be restored until such conditions or defects are corrected.
B. 
The customer system should be open for inspection at all reasonable times to authorized representatives of the city to determine whether cross connections or other structural or sanitary hazards, including violations of this chapter, exist. When such a condition becomes known, the city shall deny or immediately discontinue service to the premises by providing for a physical break in the service line until the customer has corrected the condition(s) in conformance with the department of environmental protection regulations and this chapter relating to cross connections.
C. 
No person shall construct or install or contract with another person for the construction or installation of any air gap separation with tank and pump arrangement, reduced pressure backflow preventer, or double check value assembly required by the department of environmental protection or this chapter unless a design data sheet with plans showing the method of protection of the city public water supply has been approved by the city for the installation of such device.
D. 
Prior to the installation of any pressure or atmospheric vacuum breaker, backflow preventer with intermediate atmospheric vent, or barometric loop, the plans and specifications for the plumbing work must receive a permit issued pursuant to 248 CMR 2.04(3) by the plumbing inspector. For these devices, a plumbing permit issued under 248 CMR. 2.04(3) shall constitute installation approval pursuant to these regulations.
E. 
Any person owning or occupying any premises where a cross connection is present shall apply annually to the city for a permit for each reduced pressure backflow preventer and double check valve assembly installed on the premises. Applicants for the annual permit must be made on the Massachusetts Department of Environmental Protection permit application form on or before January 1st of each year. Applications must be accompanied by the appropriate permit fee and the owner inspection and maintenance report form.
F. 
The Department of Environmental Protection shall revoke any approval or permit for any installation or change in installation of any backflow prevention device which is found to be in noncompliance with 310 CMR 22.22.
G. 
It shall be the duty of the customer-user at any premises where backflow prevention devices are installed to have certified inspections performed on reduced pressure backflow devices twice each year by the city, and double check valve assemblies shall have certified inspections performed once each year by the city. In those instances where the city deems the hazard to be great enough, the city may require certified inspections at more frequent intervals. These inspections and tests shall be at the expense of the customer and shall be performed by the city or its agents. These assemblies shall be repaired, overhauled or replaced by the customer, at the customer's expense, whenever such assemblies are found to be defective. Records of such tests, repairs or overhaul shall be kept and made available to the city.
(C.O. 07-23 § 1 (part))
The city shall maintain the following records and reports: (1) all survey and inspection reports; (2) copies of backflow device tests and re-tests; (3) copies of lists, summaries and annual reports submitted to the Department of Environmental Protection; (4) design data sheets and plumbing plans; and (5) copies of violation report forms.
The water customer shall maintain the following records and reports: (1) copies of violation report forms; (2) copies of all backflow device tests and re-tests; and (3) copies of design data sheets and plumbing plans.
(C.O. 07-23 § 1 (part))
A. 
Any person or entity violating this chapter, by maintaining a cross connection without a permit, or maintaining a cross connection without installing the appropriate backflow prevention device required by the Massachusetts Department of Environmental Protection or this chapter, is subject to a fine of up to three hundred dollars per offense. Each day that the owner is in violation shall constitute a separate offense.
B. 
Any violation of this chapter shall be subject to the administrative penalty provisions of 310 CMR 5.00.
C. 
In order to ensure the delivery of a fit and pure water supply, the city may issue a written order, pursuant to M.G.L. c. 111, Section 160 requiring the supplier of water to cease supplying water to any premises if one or more cross connections are maintained in violation of the requirements of this chapter, or requiring any person to take such actions as are reasonable and necessary to prevent or to eliminate cross connections.
D. 
The plumbing inspector, the health agent and/or code enforcement officers of the board of health shall have the right to enforce this chapter pursuant to the noncriminal disposition procedures set forth in Chapter 1.12.
