1 CHAPTER -0 DRINKING WATER STANDARDS, MONITORING, AND REPORTING Definitions For Public Water Systems. For the purpose of this chapter and Chapters - and -0, F.A.C., the following words, phrases, or terms shall have the following meaning: (1) through () No change. New subsection () is being added under Rule to define the word backflow. This definition of backflow is consistent with definitions of backflow in the Third Edition of AWWA Manual M1, Recommended Practice for Backflow Prevention and Cross-Connection Control, and the American Water Works Association s Water Distribution Systems Handbook, both of which are engineering references incorporated into Rule -.0, F.A.C. 1 () BACKFLOW means the reversal of flow of water in a public water system or customer s potable water system in such a way that contaminants or foreign substances enter the public water system or customer s potable water system through a cross-connection. Foreign substances are any substances other than the potable water being supplied by the public water system, including gases, liquids, or solids, such as chemicals, water products, steam, water from other sources (potable or nonpotable), or any matter that may change the color or taste of water or add odor to water. 1 () through (1) renumbered () through () Subsection () under Rule is being renumbered and revised to make the definition of cross-connection consistent with definitions of cross-connection in the Third Edition of AWWA Manual M1, Recommended Practice for Backflow Prevention and Cross-Connection Control, and the American Water Works Association s Water Distribution Systems Handbook, both of which are engineering references incorporated into Rule -.0, F.A.C () () CROSS-CONNECTION means an actual or potential connection between any part of a public water system or customer s potable water system and any other environment containing contaminants or foreign substances in a manner that, under any circumstances, would allow contaminants or foreign substances to enter the public water system or customer s potable water system any physical arrangement whereby a public water supply is connected, directly or indirectly, with any other water supply system, sewer, drain, conduit, pool, storage reservoir, plumbing fixture, or other device which contains or may contain contaminated water, sewage or other waste, or liquid of unknown or unsafe quality which may be capable of imparting contamination to the public water supply as the result of backflow. Foreign substances are any substances other than the potable water being supplied by the public water system, including gases, liquids, or solids, such as chemicals, steam, water from other sources (potable or nonpotable), or any matter that may change the color or taste of water or add odor to water.

5 CHAPTER - PERMITTING, CONSTRUCTION, OPERATION, AND MAINTENANCE OF PUBLIC WATER SYSTEMS -.0 Engineering References for Public Water Systems. In addition to the requirements of this chapter, the requirements and standards contained in the following technical publications are hereby incorporated by reference and shall be applied in determining whether permits to construct or alter public water system components, excluding wells (but including well pumping equipment and appurtenances), shall be issued or denied. Each of these publications is available from the publisher or source listed for the publication. The specific requirements contained in this chapter supersede the requirements and standards contained in these publications. Where there are conflicts between these publications, suppliers of water and construction permit applicants shall comply with any one of the publications. Where there are multiple options or alternatives in these publications, suppliers of water and construction permit applicants shall comply with any one of the options or alternatives. The Department shall allow exceptions to the requirements and standards in these publications if suppliers of water or construction permit applicants provide justification for each exception and provide alternative design and construction features that achieve the same purpose and that afford a similar level of strength, durability, reliability, and public health protection. (1) through () No change. Subsection () under Rule -.0 is being revised to list the latest edition (i.e., the Third Edition dated 00) of AWWA Manual M1, Recommended Practice for Backflow Prevention and Cross-Connection Control () Recommended Practice for Backflow Prevention and Cross-Connection Control, AWWA Manual M1, Third Second Edition, 00, 10, American Water Works Association (AWWA).

Subsection (1) under Rule -.0 is being revised to State that cross-connections are prohibited except where an appropriate backflow preventer is installed to control, and prevent backflow through, the cross-connection. It is not practical to prohibit or eliminate all cross-connections, and this change is consistent with Section 0. in the Florida Building Code, Plumbing, which states, Cross connections shall be prohibited, except where approved protective devices are installed. State that appropriate backflow preventers for various applications are described in AWWA Manual M1 and in subparagraph -.0()(a). Clarify that a public water system may connect to another public water system of the same type without installing a -1- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

6 backflow preventer if both systems are being operated and maintained in accordance with Chapter -, F.A.C., and Chapters -0 and -0, F.A.C. 1 (1) Cross-connections, as defined in Rule -0.00, F.A.C., are is prohibited except where an appropriate type of backflow preventer is installed to control, and prevent backflow through, the cross-connection. Appropriate types of backflow preventers for various applications are described in AWWA Manual M1 as incorporated into Rule -.0, F.A.C., and in subparagraph -.0()(a)., F.A.C. A However, a person who owns or manages a public water system may interconnect to another public water system of the same type without installing a backflow preventer if both that systems are being is operated and maintained in accordance with this chapter and Chapters -0 and -0, F.A.C. Subsection () under Rule -.0 is being revised to Specify that only community water systems (CWSs) must establish and implement a written cross-connection control program. Few non-community water systems are served by reuse systems regulated under Part III of Chapter -, F.A.C. Furthermore, a cross-connection control program for non-community water systems generally would involve simply complying with the Florida Building Code instead of ensuring backflow protection at service connections as discussed under subsection (). Under paragraph (a), specify the following seven elements to be included in written cross-connection control programs: o Legal authority for the program. o A policy establishing where backflow protection at water service connections is mandatory. o A policy regarding installation/ownership, testing, and maintenance of backflow preventers at service connections and regarding testing and maintenance of internal backflow preventers accepted by the CWS in lieu of backflow preventers at service connections. o Procedures for assessing new or existing service connections to determine the need for backflow preventers at service connections. o Procedures for keeping cross-connection control program records. o Procedures for educating the public about cross-connection control and backflow prevention. o Procedures for investigating, and responding to, backflow incidents. Under subparagraph (a)1., clarify that legal authority for a cross-connection control program may be established in an ordinance for publicly owned CWSs or in service rules and regulations, service contracts, or a resolution for investor-owned CWSs. Under subparagraph (a). o Clarify that, except as otherwise indicated, backflow protection at service connections shall be at least as stringent as recommended in Chapters and of AWWA Manual M1. o Clarify that, contrary to recommendations in AWWA Manual M1 and consistent with longstanding Department policy, CWSs must ensure that an appropriate type of backflow preventer is installed at service connections to premises where there is an auxiliary water system but need not ensure that a backflow preventer is installed at service connections to premises where there is an undeveloped auxiliary water supply or source. o Clarify the type(s) of backflow preventer required at service connections to commercial premises where there is an auxiliary or reclaimed water system and give CWSs the option to select from among a menu of service-connection backflow preventer types and additional backflow protection measures for use at residential premises where there is an auxiliary or reclaimed water system. o Clarify the type(s) of backflow preventer required at dedicated fire protection system service connections and clarify that, for premises where there is a fire protection system connected internally to the customer s potable water system, CWSs may accept an internal backflow preventer installed at the location where the fire protection system connects to the customer s potable water system in lieu of a backflow preventer at the service connection. Note that requirements for backflow preventers at dedicated fire protection system service connections are being made consistent with the Florida Building Code requirements for internal backflow preventers where fire protection systems connect internally to the customer s potable water system. o Clarify the type(s) of backflow preventer required at dedicated irrigation system service connections and clarify that, for premises where there is an irrigation system connected internally to the customer s potable water system, CWSs may accept an internal backflow preventer installed at the location where the irrigation system connects to the customer s potable water system in lieu of a backflow preventer at the service connection. Note that requirements for backflow preventers at dedicated irrigation system service connections are being made consistent with the Florida Building Code -- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

7 requirements for internal backflow preventers where irrigation systems connect internally to the customer s potable water system. o Clarify that multistoried buildings means buildings having more than four floors at or above ground level. o Clarify that a backflow preventer generally is not required at service connections to residential premises where the plumbing system meets current Florida Building Code requirements and there is no auxiliary or reclaimed water system, no fire protection system, no irrigation system, and no solar hot-water system. Under subparagraph (a). o Clarify that CWSs may install/own, test, and maintain backflow preventers at service connections by including them as part of the CWS s meter installation or in the CWS s piping or CWSs may require customers to install/own, obtain testing of, and maintain backflow preventers at service connections by requiring customers to install them in the customer s potable water system after any CWS meter installation. o Clarify that customer-owned backflow preventers at service connections shall be installed at a location as close as practical to the CWS s meter installation or the CWS s piping, but in all cases, before the first branch or water distribution system pipe off the customer s water service pipe. o Clarify that new CWS-owned double check valve assemblies and reduced-pressure principle assemblies shall conform to AWWA Standards C and C, respectively. o Clarify that backflow prevention assemblies necessary to comply with recommendations in AWWA Manual M1 as modified and clarified under subparagraph -.0()(a). must be tested immediately after installation or repair and at least annually. o Require that backflow prevention devices necessary to comply with recommendations in AWWA Manual M1 as modified and clarified under subparagraph -.0()(a). must be overhauled or replaced at least every five years. o Advise CWSs that Chapter, F.S., and Chapter A-, F.A.C., contain installation requirements, design/performance standards, and testing and maintenance requirements applicable to backflow preventers installed in piping used exclusively for a fire protection system and Chapter, F.S., Chapter 1G-1, F.A.C., and the Florida Building Code contain installation requirements, design/performance standards, and testing and maintenance requirements applicable to customer-owned backflow preventers installed in the customer s potable water system. Under subparagraph (a). o Clarify that CWSs shall assess new service connections (to determine the need for backflow preventers at the service connections) before providing water service to the service connections. o Clarify that CWSs shall assess existing service connections (to determine the need for backflow preventers at the service connections) whenever there is a change in the customer of record and require that all CWSs except non-community water systems that are reclassified as CWSs assess all existing service connections at least once by no later than December 1, 01 (five years after the deadline for submitting a written cross-connection control program complying with subparagraph (a) to the Department for approval). Non-community water systems that are reclassified as CWSs are being required to assess all existing service connections at least once within two years after the system is reclassified or by December 1, 01, whichever occurs later. Under subparagraph (a)., clarify the type of cross-connection control program records to be kept by CWSs and for how long. CWSs are being required to keep a copy of the latest assessment questionnaire or inspection report for each service connection indefinitely; keep an up-to-date inventory of backflow preventers installed at service connections and backflow preventers installed at locations where a fire protection or irrigation system is connected internally to the customer s potable water system if the CWS accepts such internal backflow preventers in lieu of backflow preventers at service connections; keep records of backflow preventer tests for at least five years; and keep annual cross-connection control program activities reports and backflow incident reports for at least five years. Under subparagraph (a)., clarify that CWSs must include a brief description of their cross-connection control program in their consumer confidence report and must distribute educational brochures about cross-connection control and backflow prevention to customers at least every three years. Under paragraph (b), clarify that CWSs may establish cross-connection control programs with more elements, or with more stringent requirements, than those specified in paragraph (a). Under paragraph (c), require that all CWS submit a written cross-connection control program complying with paragraph (a) to the Department for approval and that CWSs submit any subsequently revised written cross-connection control program to the Department for approval. Existing CWSs are being required to submit a program to the Department before January 1, 01; new CWSs are being required to submit a program to the Department before the CWS is placed into operation or before January 1, 01, whichever occurs later; and non-community water systems that are reclassified as CWSs are being required to submit a program to the Department within one year after the system is reclassified or before January 1, 01, whichever occurs later. Under paragraph (d), require that CWSs prepare an annual cross-connection control program activities report for the Year 01 and each subsequent year and submit it to the Department within three months after the end of each reporting year. 1 () Community water systems, (CWSs) and all public water systems that have service areas also served by reclaimed water systems regulated under Part III of Chapter -, F.A.C., shall establish and implement a written -- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

Subsection () under Rule -.0 is being revised to State that prohibited cross-connections either must be eliminated or must be controlled by installation of an appropriate backflow preventer instead of stating that prohibited cross-connections must be eliminated by installation of an appropriate backflow preventer. Installation of an appropriate backflow preventer does not eliminate a cross-connection but instead controls the cross-connection by preventing backflow through the cross-connection. State that the water system must ensure that a prohibited cross-connection is eliminated or is controlled by installation of a -1- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

17 backflow preventer instead of stating that the water system itself must eliminate the cross-connection or install a backflow preventer. The water system could install the backflow preventer if the system will own and maintain the backflow preventer, or the water system could require the customer to install the backflow preventer. Change the phrase backflow prevention device to backflow preventer. A backflow preventer is a means, assembly, or device that prohibits backflow, whereas a backflow device is a category of backflow preventers that generally do not have test cocks and shutoff valves to allow for field testing in place. State that the water system shall discontinue service until the cross-connection is controlled or eliminated instead of stating that the water system shall discontinue service until the contaminant source is eliminated. State that appropriate backflow preventers for various applications are described in AWWA Manual M1 and in subparagraph -.0()(a). 1 () Upon discovery of a prohibited cross-connection, public water systems shall either shall ensure that the cross-connection is eliminated; shall ensure that an appropriate backflow preventer is installed to control, and prevent backflow through the cross-connection; eliminate the cross-connection by installation of an appropriate backflow prevention device acceptable to the Department or shall discontinue service until the cross-connection contaminant source is controlled by a backflow preventer or eliminated. Appropriate backflow preventers for various applications are described in AWWA Manual M1 as incorporated into Rule -.0, F.A.C., and in subparagraph -.0()(a)., F.A.C. New Subsection () is being added under Rule -.0 to Clarify that water systems must telephone the appropriate DEP District Office or ACHD as soon as possible, but no later than noon of the next business day, after discovery of a backflow incident. Require that water systems submit a written backflow incident report to the appropriate DEP District Office or ACHD within one month after the discovery of a backflow incident () Public water systems shall telephone, and speak directly to a person at, the appropriate Department of Environmental Protection (DEP) District Office or Approved County Health Department (ACHD) as soon as possible, but never later than noon of the next business day, after discovery of a backflow incident. The phrase backflow incident means an event where contaminants or foreign substances (i.e., any substances other than the potable water being supplied by the public water system, including gases, liquids, or solids, such as chemicals, water products, steam, water from other sources [potable or nonpotable], or any matter that may change the color or taste of water or add odor to water) is found within a public water distribution system or a customer s potable water system and the occurrence of the contaminants or foreign substance is known, or reasonably suspected, to have been caused by backflow as defined in Rule -.00, F.A.C. Also, within one month after discovery of a backflow incident, public water systems shall prepare and submit to the appropriate DEP District Office or ACHD a written backflow incident report that includes the following information: (a) The date and approximate time of discovery of the backflow incident. (b) The source and cause, or suspected source and cause, of the backflow incident. -1- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

18 (c) The type and concentration of contaminants or foreign substances found within the public water distribution system or the customer s potable water system as a result of the backflow incident and the portion of the public water distribution system affected by the backflow incident. (d) The precautionary and corrective actions taken in response to the backflow incident and the date and approximate time of completion of each action. (e) To the extent known by the public water system, the number and type of illnesses or physical health problems reportedly resulting from the backflow incident. Existing subsection () under Rule -.0 is no longer necessary and being deleted because Subsections (1), (), and () under Rule -.0 are being revised to specify that appropriate backflow preventers for various applications are described in AWWA Manual M1 and in subparagraph -.0()(a)., and Chapter in AWWA Manual M1 already contains detailed descriptions of each type of appropriate backflow preventer. Subsection () under Rule -.0 is being revised to specify that customer installed/owned backflow preventers at service connections shall be installed at a location as close as practical to the community water system s meter installation or the community water system s piping, but in all cases, before the first branch or water distribution pipe of the customer s water service pipe () Only the following are considered to be backflow prevention devices. They shall be installed in agreement with and under the supervision of the supplier of water or his designated representative (plumbing inspector, etc.) at the consumer's meter, at the property line of the consumer when a meter is not used, or at a location designated by the supplier of water or the Department. The devices are: (a) Air gap separation A physical separation between the free-flowing discharge end of a potable water supply pipeline and an open or non-pressure receiving vessel. An "approved airgap separation" shall be at least double the diameter of the supply pipe measured vertically above the top of the rim of the vessel. In no case shall it be less than 1 inch. (b) Reduced pressure backflow preventer A device containing within its structure a minimum of two independently acting approved check valves, together with an automatically operating pressure differential relief valve located between the two check valves. The first check valve reduces the supply pressure a predetermined amount so that during normal flow and at cessation of normal flow the pressure between the 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 checks less than the supply pressure. The unit shall include tightly closing shutoff valves located at each end of the device, and each device shall be fitted with properly located test cocks. (c) Atmospheric vacuum breaker A backflow prevention device which is operated by atmospheric pressure -1- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00

19 in combination with the force of gravity. The unit is designed to work on a vertical plane only. The one moving part consists of a poppet valve which must be carefully sized to slide in a guided chamber and effectively shut off the reverse flow of water when a negative pressure exists. (d) Pressure vacuum breaker A pressure vacuum breaker is similar to an atmospheric vacuum breaker except that the checking unit poppet valve is activated by a spring. This type of vacuum breaker does not require a negative pressure to react and can be used on the pressure side of a valve. (e) Double check valve assembly An assembly composed of two single, independently acting, check valves, including tightly closing shutoff valves located at each end of the assembly and suitable connections for testing the water tightness of each check valve. A check valve is a valve that is drip-tight in the normal direction of flow when the inlet pressure is one psi and the outlet pressure is zero. The check valve shall permit no leakage in a direction reverse to the normal flow. The closure element (e.g., clapper) shall be internally weighted or otherwise internally loaded to promote rapid and positive closure. (f) Residential Dual Check A compact unit manufactured with two independent spring actuated check valves. The residential dual check is acceptable only as added back-flow prevention in areas served by reuse systems defined in Chapter -, Part III, F.A.C., when the cross connection control program identifies activities specific to ()(a) and ()(b) of this section. Subsection () under Rule -.0 is no longer necessary and is being deleted because Public education is an important element of all cross-connection control programs (not just those cross-connection control programs specific to reuse systems regulated under Chapter -, Part III, F.A.C.), and thus, subsection () under Rule -.0 is being revised to specify that all cross-connection control programs shall have procedures for educating the public about cross-connection control and backflow prevention. Subsection () under Rule -.0 is being revised to clarify the circumstances under which dual check valve devices may be used/allowed as backflow protection at service connections to residential premises with a reclaimed water system and to specify additional backflow protection measures, including premises inspections, for use in conjunction with dual check valve devices at service connections () Cross-connection control programs specific to reuse systems defined in Chapter -, Part III, F.A.C., shall consider the following: (a) Enhanced public education efforts towards prevention of cross connections. (b) Enhanced inspection programs for portions of the distribution system in areas of reuse for detection and elimination of cross connections. (c) Dual check valves shall be considered acceptable for reducing risks from back-flow only at residential properties served by reclaimed water unless: -1- Chapter -, F.A.C./Rule Development Workshop Draft/January 1, 00
