ADMINISTRATION AND ENFORCEMENT
All duly appointed employees of the Water Department, under the direction of the Water Superintendent, shall have free access at all reasonable hours of the day to any and all parts of structures and premises in which water is or may be delivered for the purposes of inspecting connections, the conditions of conduits and fixtures, and the manner and extent in which the water is being used. The Water Department does not, however, assume the duty of inspecting the customer’s line, plumbing, and equipment, and shall not be responsible therefor.
(Prior Code, § 51.65) (Ord. 216, passed 6-3-1991)
(A) Responsibility for customer equipment. The Water Department shall not be liable for any loss or damage of any nature whatsoever caused by any defect in the customer’s line, plumbing, or equipment, nor shall the Water Department be liable for loss or damage due to interruption of service or temporary changes in pressure. The customer shall be responsible for valves on his or her premises being turned off when the water service is turned on.
(B) Responsibility for Water Department equipment. Water Department equipment on the customer’s premises remains the property of the Department and may be repaired, replaced, or removed by the Department employees at any time without the consent of the customer. No payment will be made to the property owner for the right to install, maintain, replace, or remove Water Department equipment on his or her premises. The property owner must keep vicious dogs or other animals secured or confined to avoid interference with the utility operation and maintenance.
(C) Damage to Water Department equipment. The customer shall be liable for any damage to equipment owned by the Water Department which is caused by an act of the customer, his or her tenants, agents, employees, contractors, licensees, or permittees. Damage to equipment shall include, but not be limited to, breaking of seals and locks, tampering with meters, injury to meters, including damages by hot water or steam, and damaged meter boxes, curb stops, meter stops, and other appurtenances.
(Prior Code, § 51.66) (Ord. 216, passed 6-3-1991)
No employee of the Water Department is authorized to suspend or alter any of the policies, rules, and regulations cited herein without specific approval or direction of the City Council, except in cases of emergency involving loss of life or property or which would place the water system operation in jeopardy.
(Prior Code, § 51.67) (Ord. 216, passed 6-3-1991)
CROSS-CONNECTION CONTROL
(A) (1) The city shall be responsible for the protection of the public from pollution due to the backflow or back siphonage of contaminates or pollutants through the water service connection.
(2) If, in the judgment of the city, an approved backflow device is required at the city’s water connection to any customer’s premises, written notice shall be given to said customer to install an approved backflow prevention device at each service connection to the customer’s premises.
(B) The customer shall, within 90 days, install such approved device, or devices, at his or her own expense, and failure or refusal, or inability on the part of the customer to install said device or devices within 90 days, shall constitute grounds for discontinuing water service to the premises until such device or devices have been properly installed and/or be subject to the penalty stated in § 51.999.
(Prior Code, § 51.75) (Ord. 98-229, passed 12-10-1998) Penalty, see § 51.999
For the purpose of this subchapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
AIR GAP. A physical separation sufficient to prevent backflow between the free flowing discharge end of the potable water system and any other system. Physically defined as a distance equal to twice the diameter of the supply side pipe diameter but never less than one inch.
APPROVED. Accepted by the city as meeting an applicable specification stated or cited in this regulation, or as suitable for the proposed use.
ATOMOSPHERIC VACUUM BREAKER. A device that prevents back siphonage by creating an atmospheric vent when there is either a negative pressure or sub-atmospheric pressure on a water system.
AUXILIARY WATER SUPPLIES. Any water supply, on or available, to the premises other than the supplier’s approved public potable water supply.
BACK PRESSURE. A condition in which the owner’s system pressure is greater than the supplier’s system pressure.
BACKFLOW. The flow of water or other liquids, mixtures, or substances, under positive or reduced pressure in the distribution pipes of a potable water supply from any source other than its intended source.
BACKFLOW PREVENTER. A device or means designed to prevent backflow or back siphonage. Most commonly categorized as air gap, reduced pressure principle device, double check valve assembly, pressure vacuum breaker, atmospheric vacuum breaker, hose bib vacuum breaker, or double check with intermediate atmospheric vent. Any device must be classified as an approved backflow device by the state’s Health Division.
BACK SIPHONAGE. The flow of water or other liquids, potable water supply system from any source other than its intended source, caused by the sudden reduction of the pressure in the potable water supply system.
CONTAINMENT. A method of backflow prevention that requires a backflow prevention device at the water service entrance.
CONTAMINANT. Any substance that will impair the quality of the water to a degree that it creates a serious health hazard to the public leading to poisoning or the spread of disease.
CROSS-CONNECTION. Any actual or potential connection between the public water supply and a source of contamination or pollution.
DEGREE OF HAZARD. The danger posed by a particular substance or set of circumstances is:
(1) LOW HAZARD. Generally, a low degree of hazard is one that does not affect health, but may be esthetically objectionable; or
(2) HIGH HAZARD. One that could cause serious illness or death.
DIVISION. The State of Oregon Public Health Division.
DOUBLE CHECK VALVE WITH INTERMEDIATE ATMOSPHERIC VENT. A device having two spring loaded check valves separated by an atmospheric vent chamber.
FIXTURE ISOLATION. A method of backflow prevention in which a backflow prevention device is located to correct a cross-connection at an in-plant location rather than at a water service entrance.
HOSE BIBB VACUUM BREAKER. A device which is permanently attached to a hose bib and which acts as an atmospheric vacuum breaker.
OWNER. Any person who has legal title to, or license to operate or habitat in, a property upon which a cross-connection inspection is to be made or upon which a cross-connection is present.
PERMIT. A document issued by the utility which keeps track of the devices and allows the person to use a backflow prevention device.
PERSON. Any individual, partnership, company, public or private corporation, political subdivision or agency of the state division, agency or instrumentality or the United States, or any other legal entity.
POLLUTANT. A foreign substance that, if permitted to get into the public water system, will degrade its quality so as to 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 water for domestic use.
PRESSURE VACUUM BREAKER. A device containing one or two independently operated spring-loaded air inlet valve located on the discharge side of the check or checks. The device includes tightly closing shut-off valves on each side of the check valves and properly located test cocks for the testing of the check valve(s).
PUBLIC WORKS SUPERINTENDENT. The superintendent, or his or her delegated representative, in charge of the city’s Water Department. This person is invested with the authority and responsibility for the implementation of a cross-connection control program and for the enforcement of the provisions of the subchapter.
REDUCED PRESSURE PRINCIPLE BACKFLOW PREVENTER. An assembly consisting of two independently operating approved check valves with an automatically operating differential relief valve located between the two check valves, tightly closing shut-off valves on each side of the check valves, plus properly located test cocks for the testing of the check valves and the relief valves.
UTILITY. The City Water Department.
WATER SERVICE ENTRANCE. That point in the owner’s water system beyond the sanitary control of the Water Department; generally considered to be the outlet end of the water meter and always before any unprotected branch.
