CONSUMER. The owner or person in control of any premises supplied by or in any manner connected to a public water system.
CONSUMER'S WATER SYSTEM. Any water system, located on the consumer's premises, supplied by or in any manner connected to a public water system. A household plumbing system is considered to be a consumer's water system.
CONTAMINATION. An impairment of the quality of the potable water by sewage, industrial fluids, or waste liquids, compounds or other materials to a degree which creates an actual or potential hazard to the public health through poisoning or through the spread of disease.
CONTROLLED CROSS-CONNECTION. A connection between a potable water system and any other water system with an approved backflow prevention assembly properly installed and maintained so that it will continuously afford the protection commensurate with the degree of hazard.
CROSS-CONNECTION. Any physical connection or arrangement of piping or fixtures between two otherwise separate piping systems one of which contains potable water and the other non-potable water or industrial fluids of questionable safety, through which, or because of which, backflow may occur into the potable water system. This would include any temporary connections such as swing connections, removable sections, four-way plug valves, spools, dummy section of pipe, swivel or change-over devices or sliding multiport tube.
CROSS-CONNECTION CONTROL BY CONTAINMENT. The installation of an approved backflow prevention assembly at the water service connection to any customer's premises where it is physically and economically infeasible to find and permanently eliminate or control all actual or potential cross connections within the customer's water system; or, it shall mean the installation of an approved backflow prevention assembly on the service line leading to and supplying a portion of a customer's water system where there are actual or potential cross-connections which cannot be effectively eliminated or controlled at the point of the cross-connection.
DEGREE OF HAZARD. A term derived from an evaluation of the potential risk to the public health and the adverse effect of the hazard upon the potable water system.
DOUBLE CHECK VALVE ASSEMBLY. An assembly of two, independently operating, approved check valves with tightly closing shut-off valves on each end of the check valves, plus, properly located test cocks for the testing of each check valve. The entire assembly shall meet the design and performance specifications as determined by a laboratory and field evaluation program resulting in an approval by a recognized and certified testing agency for backflow prevention assemblies. To be approved these assemblies must be EPA approved and readily accessible for in-line testing and maintenance.
HEALTH HAZARD. Any condition, device or practice in the water supply and its operation which creates, or in the judgment of the Mayor, may create a danger to the health and well-being of any water consumer. "Severe" as used to qualify "health hazard" means a hazard to the health of any consumer that could reasonably be expected to result in significant morbidity or death.
INDUSTRIAL FLUIDS SYSTEM. Any system containing a fluid or solution which may be chemically, biologically, or otherwise contaminated or polluted in a form or concentration such as would constitute a health, system, pollutional or plumbing hazard if introduced into an approved water supply. This may include, but is not to be limited to polluted or contaminated waters: all types of process waters and used waters originating from the public potable water system which may have deteriorated in sanitary quality, chemicals in fluid form; plating acids and alkalines; circulating cooling waters connected to an open cooling tower and/or cooling towers that are chemically or biologically treated or stabilized with toxic substances; contaminated natural waters such as from wells, springs, streams, rivers, lakes, bays, harbors, seas, irrigation canals or systems, etc., oils, gases, glycerine, paraffins, caustic and acid solutions and other liquid and gaseous fluids used for firefighting purposes or for industrial or other purposes.
INTERCHANGEABLE CONNECTION. An arrangement or device that will allow alternate but not simultaneous use of two sources of water.
MAY. It is permissive.
MAYOR. The Mayor of the village or his authorized representative.
NONPOTABLE WATER. Any water which is not approved for human consumption, personal or culinary use.
PLUMBING HAZARD. A plumbing type cross-connection in a consumer's potable water system that has not been properly protected by an approved air gap or approved backflow prevention assembly.
POLLUTION. The presence of any foreign substance (organic, inorganic, or biological) in water which tends to degrade its quality so as to constitute a 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 and unreasonably affect such waters for domestic use.
POLLUTIONAL HAZARD. An actual or potential threat to the physical properties of the water system or to the potability of the consumer's potable water system which would constitute a nuisance or be aesthetically objectionable or could cause damage to the system or its appurtenances but would not be dangerous to health.
POTABLE WATER. Any water which, according to recognized standards, is safe for human consumption, culinary and domestic purposes.
PUBLIC WATER SYSTEM. The potable water system publicly owned and operated by the village.
REDUCED PRESSURE PRINCIPLE ASSEMBLY. An assembly of two, independently acting, approved check valves together with an operating, mechanically independent differential pressure relief valve located between the check valves and at the same time below the first check valve. The unit shall include properly located test cocks and tightly closing shut-off valves at each end of the assembly. The entire assembly shall meet the design and performance specifications as determined by a laboratory and a field evaluation program resulting in an approval by a recognized and certified testing agency for backflow prevention assemblies. The assembly shall operate to maintain the pressure in the zone between the two check valves at an acceptable level less than the pressure on the public water supply side of the assembly. At cessation of a normal now
the pressure between the two check valves shall be less than the pressure on the public water supply side of the device. In case of leakage of either of the check valves the differential relief valve shall operate to maintain the reduced pressure in the zone between the check valves by discharging to the atmosphere. When the inlet pressure is two pounds per square inch or less, the relief valve shall open to the atmosphere. To be approved these assemblies must be EPA approved. They must be readily accessible for in-line testing and maintenance and must be installed in a location where no part of the assembly will be submerged.
SERVICE CONNECTION. The terminal end of a service connection from the public water system, i.e., where the water purveyor loses sale jurisdiction and sanitary control over the water system at its point of delivery to the customer's water system. If a meter is installed at the end of a service connection, then "service connection" means the downstream end of the meter. There should be no unprotected take-offs from the service line ahead of any meter or any backflow prevention assembly located at the point of delivery to the customer's water system. Service connection shall also include water service connection from a fire hydrant and all other temporary or emergency water service connections from the public potable water system.
SHALL. It is mandatory.
SYSTEM HAZARD. An actual or potential threat of severe damage to the physical properties of the public potable water system or the consumer's potable water system or of a pollution or contamination which would have a protracted effect on the quality of the potable water in the system.
USED WATER. Any water supplied by a water purveyor from a public potable water system to a consumer's water system after it has passed through the point of delivery and is no longer under the sanitary control of the water purveyor.
VILLAGE. Village of Smithville, Ohio, or authority.
WATER PURVEYOR. The owner or operator of a public potable water system, i.e., the village.
