(A) On customer request. Each customer about to vacate any premises supplied with water service by the Water Department shall give the Water Department a request to discontinue service prior to the specific date service is to be discontinued. The customer is responsible for all water supplies to the premises until water service is actually discontinued by the city or 2 days after the city received notice, whichever occurs first.
(B) Nonpayment of bills. A customer's water service may be discontinued if the water bill is not paid in accordance with the procedures listed in these rules and regulations.
(C) Improper customer facilities.
(1) Unsafe facilities. The Water Department may refuse to furnish water and may discontinue service to any premises without prior notice where plumbing facilities, appliances, or equipment using water are dangerous, unsafe, or not in conformity with the State Plumbing Code;
(2) Cross connections or physical connections with other water supplies or systems. Neither cross connections nor physical connections of any kind shall be made to any other water supply, whether private or public, without the written approval of the Water Department. Included in this category are all pipelines, appurtenances, and facilities of the Water Department's system; and all pipes, appurtenances, pumps, tanks, storage reservoirs, facilities, equipment, and appliances of other systems, whether located within or on public or private property, or the premises of a water user. Except with written approval of the Water Department, no person shall connect a separate source of water supply to a plumbing system theretofore connected to the city's water system, nor shall any person by application therefore cause the city water system to be connected to a plumbing system supplied also by another water source, whether such a separate water source can be separated by a valve or not. Whenever cross connection to other water supply into the city system is found or whenever any other condition is found which presents the possibility of contamination or pollution, the water supply to the premises and/or other premises from which cross connection is made shall be discontinued immediately until the cross connection is eliminated or the condition remedied. The control or elimination of cross connections shall be in accordance with the following cross connection control requirements.
(a) A backflow prevention device shall be installed where a cross connection may exist.
(b) For community water distribution systems where the following conditions may exist on the user premises, the device shall be installed in or just ahead of the user service pipeline or immediately inside the building:
1. Where an auxiliary water supply exists which may not be potable;
2. Where any substance is handled under pressure in a manner that may permit its entry into the potable system. This includes process water and water originating from the potable system which may have deteriorated in quality; and/or
3. Where an internal piping cross connection exists that is not correctable or where an intricate plumbing arrangement makes it impractical to determine whether or not a cross connection may exist.
(c) The type of protection required for cross connection control shall depend upon the degree of hazard as follows:
1. Where there is an auxiliary water supply as stated in division (C)(2)(b)1. above, the potable system shall be protected by an approved air gap separation or an approved reduced pressure principal backflow prevention device;
2. Where a substance that would be objectionable but not hazardous to health, if introduced into the potable system, an approved double check valve assembly shall be provided; and
3. Where there is material dangerous to health which is handled in such a manner that may permit entry into the potable system, an approved air gap separation or an approved reduced pressure principle backflow prevention device shall be provided. Examples of premises where these conditions may exist include sewage treatment plants, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries, plating works, medical clinics, and car washes
(d) A protective device required herein shall be a model approved by the Oregon Health Division. A double check valve or a reduced pressure principal backflow prevention device, to be approved, shall be one which has successfully passed performance tests by a reputable testing laboratory either in conformance with standards established by the University of Southern California Engineering Center Report 48-101 of 1-30-1959, or those standards presented in the Manual of Cross Connection Control, Fifth Edition, published by the Foundation for Cross Connection Control Research or in the Cross Connection Control Manual, Second Edition, July 1973, published by the Pacific Northwest Section of the American Water Works Association.
(e) All presently installed backflow prevention devices which do not meet the requirements of this section but were approved devices for the purposes described herein at the time of installation and which have been properly maintained shall, upon inspection, be excluded from the requirements of this chapter so long as they satisfactorily protect the water system. Whenever the existing device is moved from the present location or requires more than minimum maintenance or constitutes a hazard to health, the unit shall be replaced by a backflow prevention device meeting the requirements of this section.
(f) A pit housing a backflow prevention device shall be drained to daylight. Ample space shall be provided for access to and testing a device.
1. For the purpose of this section, the separate water source shall be considered connected to the city water system unless there be a complete break in the piping between the separate water source and the city water system. The city shall require a backflow prevention device of pattern, design, and size which it approves as reasonably adequate to prevent contamination. The city shall also regulate the location, installation, and testing of the device. These inspections and tests shall, at the expense of the owner of the property, be performed only by a person currently certified by the state as a backflow prevention device tester. Charges for the inspections and tests, when performed by the city, shall be added to the charges for water against the premises necessitating the inspection or tests.
2. Any corrective measure, disconnection or change on private property shall be at the sole expense of the person in control of the property. The cost of any change required in the city system outside the property or between the meter and the supply lines or distribution system and any charges for cut-off or disconnection shall be added to the charges for water against the premises necessitating the expenditures.
3. The Superintendent or other authorized representative shall have the right, without being considered guilty of trespass or unlawful act, to check the premises of users for physical connections with other water supplies. Any such connection shall be removed immediately by the customer; otherwise the Water Department shall discontinue any connection that it may have for the service of water to the premises.
4. All plumbing within the building served by the Water Department shall be so installed and all plumbing fixtures by back-siphonage or cross connections. Water service to any premises known or found to have the defects and hazards shall be disconnected and not restored until the defects and hazards have been eliminated.
(D) Water waste. Where water is wastefully or negligently used on a customer's premises, seriously affecting the general service, the Water Department may discontinue service if the conditions are not corrected after due notice by the Water Department.
(E) Service detrimental to others. The Water Department may refuse to furnish water and may discontinue service to any premises where excessive demand by 1 customer will result in inadequate service to others.
(F) Fraud or abuse. The Water Department will refuse or discontinue service to any premises where it is considered necessary to protect the Water Department from fraud or abuse. Discontinuance of service for 1 or both of these causes will be made immediately upon receipt of knowledge by the Water Department that the condition or conditions exist.
(G) Unauthorized turn on. Where water service has been discontinued for any reason and the water is turned on by the customer or other unauthorized person, the water may then be shut off at the main or the meter removed. The charges for shutting off the water at the main or removing the meter shall be computed at actual cost to the Water Department, plus 15% overhead, but not less than $10. These charges shall be billed to the offending customer, and water shall not be furnished to the premises until the charges are paid and the Water Department has reasonable assurance that the violation will not recur.
(H) Noncompliance with rules and regulations. The Water Department may, upon 5-days' notice, discontinue service to a customer's premises for failure to comply with any of the provisions of these rules and regulations. This division does not prevent immediate continuance when authorized by this chapter.
