(j) “Cross-connection” means any arrangement whereby backflow can occur.
(k) “Double check valve assembly” means an assembly composed of two single, independently-acting check valves, including tightly closing shut-off valves located at each end of the assembly and suitable connections for testing the water tightness of each check valve.

(r) “Person” means the state, any political subdivision, public or private corporation, individual, partnership, association, trust or other legal entity.
(s) “Pollution” means the presence in water of any foreign substance that tends to degrade its quality so as to constitute a health hazard or impair the usefulness or quality of the water to a degree which does not create an actual hazard to the public health but which does adversely affect such waters for domestic use.
(t) “Potable water” means water which is satisfactory for drinking, culinary and personal hygienic purposes and meets the requirements of the Department of Health.
(u) “Process fluids” means any fluid or solution which may be chemically, biologically or otherwise contaminated or polluted in a form or concentration such as would constitute a health, pollutional or system hazard if introduced into the public or a potable consumer's water system. This includes, but is not limited to:

(w) “Reduced pressure principle backflow prevention device” means a device containing a minimum of two independently acting check valves, together with an automatically operated pressure differential relief valve located between the two check valves. During normal flow and at the cessation of normal flow, the pressure between these two checks shall be less than the supply pressure. In case of leakage of either check valve, the differential relief valve, by discharging to the atmosphere, shall operate to maintain the pressure between the check valves at less than the supply pressure. The unit must include tightly closing shut-off valves located at each end of the device, and each device shall be fitted with properly located test cocks.
(x) “Service connection,” means the terminal end of a service line from the public water system. If a meter is installed at the end of the service, then the service connection means the downstream end of the meter.
(y) “System hazard” means a condition posing an actual or potential threat of damage to the physical properties of the public water system or a consumer's potable water system.
(z) “Pollutional hazard” means a condition through which an aesthetically objectionable or degrading material not dangerous to health may enter the public water system or a consumer's potable water system.
(aa) “Used water” means any water supplied by a water purveyor from a public water system to a consumer's water system after it has passed through the service connection and is no longer under the control of the water purveyor.
