A. 
Purpose. The department's purpose in establishing a comprehensive distribution protection program is to prevent the contamination of drinking water to the last free-flowing outlets or consumer's tap. For this reason, the department strongly advocates the elimination of all cross-connections. The installation of backflow prevention devices does not eliminate a cross-connection. The installation of backflow prevention devices is a solution when replumbing or repiping is not feasible. All cross-connection protection devices shall be approved and permitted in accordance with 310 CMR 22.22, as set forth at 310 CMR 22.22(4) and 310 CMR 22.22(7)(b). Each owner of such device shall apply for and be issued a permit by the department.[1]
[1]
Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions).
B. 
Maintenance of a cross-connection.
(1) 
No physical cross-connection shall be maintained between the distribution system of a public water system, the water of which is being used for drinking, domestic or culinary purposes, and the distribution system of any water source not approved by the department as being of safe, sanitary quality, unless said connection has been approved by the department and a permit has been issued by the department in accordance with 310 CMR 22.22.
(2) 
Subject to applicable laws and regulations, public water systems shall have the authority to terminate any water service connection to any facility where cross-connections are found to be in noncompliance with 310 CMR 22.22. The supplier shall deny water service to any premises where cross-connections exist until corrective action is taken. If necessary, water service shall be disconnected for failure to test or maintain backflow prevention devices in a manner acceptable to the supplier. If it is found that the backflow prevention device has been removed or bypassed or otherwise rendered ineffective, water service shall be discontinued unless corrections are made immediately.
(3) 
The public water system shall establish a time for completion of necessary corrections or removal of actual or potential cross-connections, taking into consideration the degree of hazard involved and the time required to obtain and to install the needed equipment. The public water system shall use every means at its disposal to obtain voluntary compliance. However, if proper protection has not been provided after a reasonable period of time (following legal notification and subject to applicable laws and regulation), the public water system shall physically separate the public water supply from the on-site piping system in such a manner that the two systems cannot again be connected by an unauthorized person.
C. 
Owners' responsibilities. The owner of any cross-connection protection device shall:
(1) 
Apply for, obtain and comply with all necessary approvals and permits from the public water system and/or the department for the maintenance of cross-connections as specified in 310 CMR 22.22, including the permit issued by the department for each cross-connection protection device;
(2)
