(B) In the case of any premises where, in the opinion of the water purveyor and/or building official, an imminent health threat is posed due to cross connection or a potential contamination hazard, water service to the facility may immediately be discontinued without prior written notice to customer/property owner. Although the city will attempt to provide notice as is reasonably practical, no notice shall be required prior to discontinuance. (4) Failure, refusal or inability on the part of the customer/property owner to install, have tested and maintain the backflow prevention assembly(s) shall be grounds for discontinuing water service to the premises until such requirements have been met as required by sections 28 .10.051, 28.10.053 through 28.10.054.
(5) Any reduction in water pressure caused by the installation of backflow prevention assembly devices shall not be the responsibility of the city. (b) Responsibilities of the customer/property owner. The customer's/property owner's system shall include those parts of the potable water conveyance facilities beyond the termination of the utility distribution system that are conveying potable water to the points of use of customer/property owner. (1) Backflow prevention assemblies shall be installed within the customer's/property owner's system at the customer's/property owner's expense at any time required by sections 28. l 0.052, 28. 10.053, or 28. 10.054 of the Code of Ordinances of the City of Lubbock and/or sections 312.9 or 608 of the 2009 International Plumbing Code, or sections P2503.7 or P2902 of the 2009 International Residential Code, or the USC Manual of Cross-Connection Control, American Water Works Association M14 Manual, as applicable. All backflow prevention devices must be installed and tested as required by: (A) Section 28.10.052, section 28. 10.053, and section 28.10.054 of the Code of Ordinances of the City of Lubbock; (B) Section 312.9 and section 608 of the 2009 International Plumbing Code; and (C) 30 TAC 290.44(h), 30 TAC 290.46U) and 30 TAC 290.47(i).

In addition to the remedies provided herein, in the event the backflow prevention assembly is installed by a licensed professional, failure by such licensed professional to follow the provisions of such permit will result in written notice to the applicable state licensing agency, in addition to being a violation of sections 28 .10.051, 28.10.053 through 28.10.054. (3) It shall be the responsibility of the customer/property owner and backflow prevention assembly tester performing the subject test(s) to send to the city the backflow prevention assembly test and maintenance records. These materials shall be delivered to the water
purveyor office of the city within ten (10) days of installation of the backflow prevention assembly. (4) The customer's/property owner's system shall be open for inspection at all reasonable times to authorized representatives of the city to determine whether cross connections or potential contamination hazards, including violations of sections 28.10.052, 28.10.053, or 28.10.054 of the Code of Ordinances of the City of Lubbock and/or sections 312.9 or 608 of the 2009 International Plumbing Code, or sections P2503.7 or P2902 of the 2009 International Residential Code, as applicable, exist. (S) If the customer or premises wherein potable water from the city is supplied or provided has an auxiliary water supply that is treated to a lesser degree than the public water supply or if the water quality is unknown, and which is either cross connected or poses a potential contamination hazard to the public water system, the public water system shall be protected against backflow or backsiphonage by an approved backflow prevention device. The described threat shall be deemed a health hazard when determining the type of approved backflow required.

Only city fire hydrant water meters with approved backflow prevention assemblies are allowed to be used within the city limits. Failure to comply with this subsection (b)(8) will result in the fire hydrant meter being removed from the premises by the water purveyor. (9) It shall be the duty of the customer/property owner at any premises where backflow prevention assemblies are installed to have certified inspections and operational tests made upon installation and at least once every three years in nonhealth hazard conditions. In those instances where the water purveyor and/or building official of the city deems the potential backflow to be a health hazard or a potential health hazard, certified inspections shall be required annually or at more frequent intervals as deemed necessary by the water purveyor.
