IMMOKALEE WATER & SEWER DISTRICT CROSS CONNECTION CONTROL PROGRAM

    1. INTRODUCTION

    2. General

      The Immokalee Water & Sewer District operates a public water utility serving the area in and around the town of Immokalee located in north central Collier County, Florida.

      Under FAC 17-555.360, Permitting and Construction of Public Water Systems, all community water systems are required to…“establish a routine cross connection control program to detect and prevent cross connections that create or may create an imminent and substantial danger to public health.” This document provides the framework for meeting this regulatory requirement. The term cross connection shall mean:

      1. Any unprotected actual or potential connection or structural arrangement between any part of the District’s potable water system, which is used and intended to supply water for drinking purposes, and any source or system containing water or substances that is not or cannot be approved as safe, wholesome and potable for human consumption.


      2. Any unprotected actual or potential connection or structural arrangement between any part of the District’s reclaimed/IQ water system, which is used and intended to supply water for irrigation, and any source or system containing water or substances that is not or cannot be approved as safe.

    3. Program Objectives

This program provides a basis from which to implement appropriate cross connection control requirements within the District’s system. Implementation of the program involves several key elements. These elements include inspection of existing customer services and on-site water use practices, risk assessment, establishing requirements and responsibility for cross connection control, establishing criteria for implementing cross connection control, establishing related guidelines and establishing the impact of non- compliance with cross connection control requirements.

      In the case of continuing conflict, the interpretation of District Director shall be final.

    3. Definitions

      The following definitions are established and shall be used in interpreting the requirements of this program.

      1. Backflow

        The undesirable reversal of flow into the District’s or consumer’s potable water system as a result of a cross connection.

        Backflow of substances from the customer’s water system into the District’s water system can be caused by backpressure or backsiphonage. Backpressure results when a customer’s water system is connected to the District’s system and the pressure in the customer’s water system is greater than the pressure in the District’s water system.

        Backsiphonage results when a negative or substantially reduced pressure is created in the District’s water system in relation of the customer’s water system.

      2. Backflow Preventer – Customer-Owned

        An assembly or means to prevent Backflow that is purchased, owned, and maintained by the water customer. The following defines backflow preventer systems which may be approved for use, by customers served by the District, on a case by case basis to protect and/or isolate areas of the Customer’s Water System:


        1. Air Gap (AG)

          The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet conveying water or waste to a tank, plumbing fixture, receptor, or other assembly and the flood level rim of the receptacle. These vertical, physical separations must be at least twice the diameter of the water supply outlet, never less than 1 inch.

        2. Reduced-Pressure Backflow Prevention Assembly (RPBA)

          The approved reduced-pressure backflow prevention assembly consists of two independently acting approved check valves together with a hydraulically operating, mechanically independent pressure differential relief valve located between the check valves and below the first check valve. These units are located between two tightly closing resilient-seated shutoff valves as an assembly and equipment with properly located resilient-seated test cocks.

        3. Double Check Valve Assembly (DCVA)

          The approved double check valve assembly consists of two internally loaded check valves, either spring loaded or internally weighted, installed as a unit between two tightly closing resilient-seated shutoff valves and fittings with properly located resilient-seated test cocks. This assembly shall only be used to protect against a non-health hazard (that is, a pollutant).

        4. Vacuum Breaker – Atmospheric Type (AVB)

          The approved atmospheric type vacuum breaker assembly consists of a float check, a check seat, and an air inlet port.

        5. Vacuum Breaker – Pressure Type (PVB)

          The approved pressure type vacuum breaker assembly consists of an independently operating internally loaded check valve and an independently operating loaded air inlet valve located on the discharge side of the check valve, with properly located resilient-seated test cocks and tightly closing resilient- seated shutoff valves attached at each end of the assembly.

      3. Backflow Preventer – District-Owned

        An assembly or means to prevent Backflow that is installed on the customer’s water service line to protect either the District’s Potable Water System or the District’s

        Reclaimed/IQ Water System, which is owned and maintained by the District. The following defines backflow preventer system which are approved for use:


        1. Reduced-Pressure Backflow Prevention Assembly (RPBA)

          The approved reduced-pressure backflow prevention assembly consists of two independently acting approved check valves together with a hydraulically operating, mechanically independent pressure differential relief valve located between the check valves and below the first check valve. These units are located between two tightly closing resilient-seated shutoff valves as an assembly and equipment with properly located resilient-seated test cocks.

    4. Certified Technician-Backflow Prevention

      The term certified technician shall mean a person employed by the District who is trained in the maintenance, repair and testing of backflow prevention devices. A certified technician will have successfully completed a training course, recognized by the State of Florida, specifically related to backflow prevention, backflow preventer testing and maintenance, and the rules and regulations applicable to cross connection control.

    5. Customer’s Water System

      The term customer’s water system shall mean water pipes and appurtenances, pumps, tanks and other facilities connected to the District’s water system downstream of the District’s RPBA, or in the case of Collier County-owned Facilities, downstream of the District’s service connection to the customer.

    6. Cross Connection

      A connection or potential connection between any part of the Districts water system and any other environment containing other substances in an manner that, under any circumstances would allow such substances to enter the District’s water system. Other substances may be gases, liquids or solids, such as chemicals, waste products, steam, water from other sources (potable or non-potable), or any matter that may change the color, add odor or change the chemical or biological composition of the water.

    7. District’s Water System

      The water supply facilities, treatment facilities, storage facilities, pumping facilities, transmission mains, distribution mains, water meters, and service laterals up to the customer’s side of the District’s RPBA or water meter, as applicable.

      1. District’s Water System - Potable

        This is the public potable water system which provides water of a quality that is suitable for drinking.

      2. District’s Water System – Reclaimed/IQ

        This is the public non-potable water system which treats and conveys the effluent from the wastewater treatment plant to a quality that is suitable for irrigation, but is unsuitable for drinking.

    8. Hazard, Degree of

      The term establishes the potential risk to public health and the adverse effect of the hazard upon the District’s water system.

      1. Hazard – Health

        A cross connection or potential cross connection involving any substance that could, if introduced in the potable water supply, cause death, illness, spread of disease, or have a high probability of causing such effects.

      2. Hazard – Non-Health

        A cross connection or potential cross connection involving any substance that generally would not be a health hazard but would constitute a nuisance or be aesthetically objectionable, if introduced into the potable water supply.

    9. Pollution

      The presence of any foreign substance in water that tends to degrade its quality so as to constitute a non-health hazard to impair the usefulness of the water.

    10. Water-Potable

      Water that is safe for human consumption as described by public health authority having jurisdiction.

    11. Water – Reclaimed/IQ

Highly-treated effluent from the wastewater treatment plant that is suitable for irrigation, but is not safe for human consumption.

    1. CROSS-CONNECTION CONTROL – SERVICE CONNECTIONS

    2. Services

      Services shall be defined as any connection to the District’s water system where either potable or reclaimed/IQ water is conveyed from the District’s water system to the customer’s water system through a meter. The cross connection control program for customer’s service locations shall be implemented in a manner and or a schedule as outlined hereinafter.

    3. Classification of Connections

      The purpose of generally classifying customer services into one of the following six groups is to establish a hierarchy based on the potential for cross connections which might present a hazard

      to the District system and establish a priority for site inspections. The District shall compile a list of all customer services categorizing each service into one of the following groups listed in order of hazard potential from least to greatest:

      • SINGLE FAMILY RESIDENTIAL (e.g.: one single family dwelling per lot)


      • MULTI-FAMILY RESIDENTIAL (e.g.: duplexes, apartments, condominiums, trailer parks)


      • COUNTY FACILITIES (e.g.: courthouse, parks, public library, public facilities owned and maintained by Collier County)


      • COLLIER COUNTY SCHOOL BOARD (e.g. public schools)


      • LIGHT COMMERCIAL (e.g.: restaurant, laundry, commercial office, private schools, private facilities, motels, hotels, hardware stores, supply houses, car repair facilities)


      • INDUSTRIAL (e.g.: dry cleaning, packing house, freezer facilities, manufacturing site, pest control, chemical or industrial supply houses)


      • MULTI-STORY BUILDINGS (e.g.: any building or dwelling greater than one story that has an increased potential for backflow into the District’s system)


    1. DISTRICT’S RESPONSILIBILTIES


    2. Existing Services Without Cross-Connection Control Devices

      The District shall install, own, operate, and maintain an RPBA backflow assembly on each existing service which existed prior to the effective date of this Resolution that currently does not have a cross-connection control device. At the discretion of the District, a residential area may be served by one or more RPBA’s in lieu of providing an RPBA for each service connection.

      The District shall give advance notice of when the RPBA will be installed. RPBA’s are to be installed as close as practical after the meter in order to avoid the future possibility of by-passing the device.

    3. Existing Services With Cross-Connection Control Devices

      The District shall notify all property owners that have existing Cross-Connection Control Devices at the water meter in writing of the District’s policy established by this Resolution to own, operate, and maintain RPBA’s. The notification shall also state that the District shall inspect and test all existing cross-connection control devices which existed prior to the effective date of this Resolution to verify that they are RPBA devices in good working order.

      If the RPBA is found to be in good working order, then the RPBA will become the property of the District, with the exception of facilities owned by Collier County and the Collier County School Board. Collier County and the Collier County School Board will continue to own, operate, and maintain RPBA devices for its facilities. Collier County and the Collier County

      School Board will continue to be required to furnish the District with copies of certified inspection, testing, and repair reports.

      If the existing cross-connection control device is found to be an RPBA in a condition which does not adequately protect the District’s system from potential hazards, the District shall notify the property owner in writing that they have thirty (30) days from the date of the letter to correct the situation at the customer’s cost and to notify the District when the necessary repairs have been made. At that time, the District will re-inspect the RPBA to verify that it is in good working order. Once the RPBA has been found to be in good working order, then it will become the property of the District.

      If the existing cross-connection control device is found to be in good working order but is not an RPBA, the District shall notify the property owner that the existing device does not meet the requirements as set forth in this Resolution and that arrangements will be made to minimize the amount of time that the water service will be shut off so that a new RPBA device can be installed by the District at the District’s cost.

      If the existing cross-connection device is found to be a device other than an RPBA in a condition which does not adequately protect the District’s system from potential hazards, the District shall notify the property owner in writing that they have thirty (30) days from the date of the letter to install a new RPBA at the customer’s cost and to notify the District when the installation has been completed. At that time, the District will inspect the RPBA to verify that it is in good working order. Once the RPBA has been found to be in good working order, then it will become the property of the District.

    4. New Service Connections


      All new connections to the District’s water system shall be reviewed for compliance to the requirements of this program. The District shall, as part of their normal pre-construction plan, review process, complete an evaluation of cross connection control needs for the service. The District shall define the specific cross connection control requirements for the connection. The RPBA(s) required by the District shall be paid for and installed by the developer, but shall become the property of the District upon final acceptance of the project by the District.


      The connection shall be considered as certified for service upon the District performing an inspection of the completed installation to determine that the system has been constructed in accordance with the approved construction documents.

    5. Site Inspections

      The District shall perform an annual physical inspection of each customer service location commencing on the effective date of this program. The District shall provide a continuing cross connection control inspection program through continually updating the list of customer services which have not been either inspected or certified as having appropriate cross connection control safeguards. Each customer service shall be inspected annually to determine that the customer’s on-site system and processes have not been reconfigured in a manner which would alter the potential cross connection hazard of the site. The inspections shall be conducted by a certified representative of the District staff concurrently with the testing and maintenance responsibilities

      stipulated in Section 4.6. An inspection report shall be completed for each site. A copy of the inspection report form is contained in Appendix H of the USEPA Cross-Connection Control Manual. The completion of the inspection and report shall have several objectives including:

      • Protect the District water supply from possible contamination which could be introduced through the customer’s water piping system.


      • Eliminating or controlling cross connections, either existing or future potential, between the customer’s on-site service piping, process piping and related facilities, and the District’s water system.

        District Staff shall have the authority to enter on and inspect the Customer’s property and facilities as required to accomplish the objectives of this program.

    6. Inspection Records

      The District shall maintain a file of all locations requiring inspection and all locations inspected. This file shall be available for inspection by the appropriate regulatory agencies on an as- requested basis.

    7. Testing and Maintenance

      The District shall perform an annual physical test of each RPBA at each customer service location commencing on the effective date of this program. The tests shall be conducted by a certified representative of the District staff concurrently with the inspection responsibilities stipulated in Section 4.4. A test report shall be completed for each site, and any deficiencies found shall be corrected at the time of the test. A copy of the test and maintenance report form is contained in Appendix I of the USEPA Cross-Connection Control Manual.


    8. Establishment of Flat Fee


The District shall establish a monthly flat fee for each size of RPBA based on recouping the District’s costs associated with the annual testing and repairs anticipated to be necessary. The monthly flat fee schedule is as follows:
