HomeMy WebLinkAboutEDB Response to Resident CCCP Compliance EXECUTIVE SUMMARY
AGENDA ITEM:
Recommendation to uphold the policies and procedures of the Cross-Connection Control Policy
(CCCP) as adopted by the Authority for the property owners; Sansom-210 Foxridge Drive and
Moore-2801 Stagecoach Drive.
Date: February 7, 2023
BACKGROUND:
During the 01/17/23 Board of Supervisors meeting, Mr. Sansom (210 Foxridge Drive) and Ms.
Moore(2801 Stagecoach Drive)presented comments to the Board requesting relief from CCUA's
Cross Connection Control Policy. CCUA staff was made aware there is an active pressurized
auxiliary water source(i.e.,well)on each property and had previously advised the property owners
of their compliance options with CCUA's CCCP by either 1) installing a reduced pressure
backflow prevention device (commonly known as an RP) or 2) capping and sealing the existing
co
well on the property, if the well is no longer active.

w Staff met with both Mr. Sansom and Ms. Moore on 01/26/23 at their homes subsequent to the
o f'board meeting. Both customers were informed of the intent of the CCCP and the staff
c willingness to work with the homeowners regarding concerns related to the backflow location(s)
and compliance time. While the customers disagree with the compliance requirement to install a
cc backflow device, it is required by the State of Florida and by CCUAs Cross Connection Control
policy. The purpose is to protect the public water supply.
CCCPs are State mandated plans for utilities to protect public water supply systems from potential
cross connections that could introduce contamination into the public supply system. Staff will
provide an overview presentation of the CCUA's CCCP. The policy was adopted by CCUA in
1995 and was amended in 2000.
Cross Connection Control is a preventative business, not a reactionary one. The program focuses
on eliminating or isolating potential backflow and cross-connection situations on the customer side
of the meter that could create backflow by back-pressure or back-siphonage in CCUA's potable
water supply. There are numerous such situations that require devices or air gaps to protect the
water system: staff will provide an overview of these situations and the CCC policy.
RECOMMENDATION:
Staff respectfully recommends Board to uphold the requirements of CCUA's CCCP. Staff will
work with the Clay County Health Department to improve communication on CCUA's CCCP, for
those property owners requesting a well permit(s). Staff will continue to work with Mr. Sansom
on relocating the RP to a mutually agreed-upon location,to avoid vehicular damage. Additionally,
staff will continue to work with Ms. Moore to allow sufficient time to consult with backflow
installers.

Re: Reduced Pressure Backflow Assembly—210 Foxridge Road
Dear Owner:
On 12/14/2022, it was brought to our attention that a private well is located at the above-
referenced property. The Clay County Utility (CCUA) has no objection to the existing private
well on your property. However, CCUA does require that a reduced pressure backflow assembly
be installed on the upstream side of the potable water meter. Without a reduced pressure
backflow assembly, this could create a potential cross-connection violation, which is prohibited
by the Florida Administrative Code (FAC) 62-555.360. If the well is not in use, your other
option would be to cap and seal the well and a backflow prevention assembly would not be
required.
The safety of the public is of the utmost important to CCUA.Now that we are aware of this
potential cross connection hazard,we have an obligation to ask that you make the necessary changes
to be in compliance with FAC Code 62-555.360 (see attached). For your convenience, I have
attached a list of contractors who have registered their backflow prevention credentials with our
office. The contractor will need to test your device after installation and generate a report. Please
provide a copy of your passing backflow report to me no later than 01/14/23 to avoid disconnection.
Thank you for your attention in this matter. Please feel free to contact me at(904)-213-2466
or via e-mail at sconner@clayutility.org,if you have any questions or require additional information.
Sincerely,

Section 1
Purpose and Intent
1.1 Schedule of Compliance
It is the intent of the Clay County Utility Authority ("CCUA") to fully comply with the
requirements of the F.A.C., Rule 62-550.360 with regard to cross-connection control;
thereby reducing potential sources of contamination and pollution of its approved water
supply system.
Since the Florida regulations pertaining to cross-connection control and backflow
prevention became effective (see Section 3.2) the Authority and/or its predecessor
organizations have required backflow prevention assemblies in accordance with F.A.C.,
Rule 62-550.360. Prior to that time, backflow prevention assemblies were not required.
CCUA has identified all prior general service accounts that are required to have backflow
prevention assemblies under current rules and has prioritized the retrofit of these based
on potential health hazards associated with each account. The CCUA is in the process of
requiring compliance by systematically addressing those retrofit accounts that present a
health hazard. The highest potential health hazards will be addressed first and staff will
then address the other health hazards in the order of priority as established by staff.
Subject to the retrofit requirements herein, those general service accounts that are
considered to be no more risk than a residential account, which do not have a well, shall
not be fitted with a backflow assembly. In addition, the CCUA is in the process of
developing a program to identify which single family residences have an on-site well.
Once those accounts are identified, the CCUA will then initiate a systematic program to
have an appropriate backflow prevention assembly installed at such locations. Such
retrofit program will be pursued as rapidly as it becomes economically feasible to do so.
CCUA's system shall be protected immediately, or as soon thereafter as is feasible,
against"known" cross-connections and any other"known" hazards which CCUA's staff
believes to be a direct threat to public health and welfare.
1.2 Protection
To protect the public potable water supply from contamination or pollution by evaluating,
and where deemed appropriate, isolating cross-connections, in the water distribution
system that will otherwise create backflow by back-pressure or back-siphonage into the
public potable water supply (Ref.: F.A.C., Rule 62-555.360, or its successor rule), subject
to the provisions of Section 1.1.
1.3 Elimination of Cross-Connections
To protect the potable water distribution system from cross-connections between the
potable water system(s) and sources of contamination as required by the applicable
governmental regulations (refer to 62-555.360).
1.4 Cross-Connection Control Program
To provide for the maintenance and operation of a continuing program of cross-
connection control which will systematically and effectively prevent the contamination or
pollution of the CCUA's potable water distribution system, as required by the Florida
Department of Environmental Protection regulations (Ref.: F.A.C., Rule 62-555.360 or
its successor rule).
Section 2
Definitions
2.1 Air-gap separation shall mean a physical separation between the free flowing discharge
end of a potable water supply pipeline and an open or non-pressure receiving vessel. An

Section 3
Authority
The following authorities are justification for establishing a cross-connection control program.
3.1 Safe Drinking Water Act
The Safe Drinking Water Act 42 U.S.C. secs. 300f, et seq. (PL 93-532), was signed into
law by Congress on December 16, 1974. The purpose of the law is to assure that the
nation's potable water supply systems meet minimum National Health Standards for the
protection of public health. In accordance with the Safe Drinking Water Act, the National
Interim Primary Drinking Water Regulations were promulgated on December 24, 1975
and became effective on June 24, 1977. These regulations replaced the Public Health
Service Drinking Water Standard of 1962. It is stated in Appendix A of the rule that
"minimum protection should include programs that result in... prevention of health
hazards, such as cross-connections." The Safe Drinking Water Act and its regulations
cover all public potable water systems with 15 or more service connections and systems
that regularly serve 25 individuals. The Safe Drinking Water Act allows states to
maintain primary enforcement responsibilities for their water quality program. However,
the state's regulations must be equal to or exceed federal regulations. The administrator
of the Environmental Protection Agency retains authority over states that do not obtain
primacy.
3.2 Florida Regulations
The State of Florida was granted primacy over the water program under the authority of
the "Florida Safe Drinking Water Act" Florida Statutes, Chapter 403, Part VI (secs.
403.850, et seq.). Regulations under the Florida Act became effective November 1977,
under Florida Administrative Code (F.A.C.), Chapter 17-22). The Florida regulations
were revised in November 1987 to address the topic of cross-connection control and
backflow prevention and incorporated more specific language than that contained in the
federal regulations. The Florida regulations (Chapter 17-22, F.A.C.) were revised again,
and renumbered in January 1989 as Florida Administrative Codes 62-550, 62-555, and
62-560. Rule 62-550.200(20), F.A.C., defines a cross-connection as "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. By-pass
arrangements, jumper connections, removable sections, swivel or changeable devices,
and other temporary or permanent devices through which or because of which backflow
could occur are considered to be cross-connections."
Rule 62-555.360(1), F.A.C., states, "Cross-connection as defined in Rule 62-550.200,
F.A.C., is prohibited."
Rule 62-555.360(2) states, "Community water systems, and all public water systems
which have service areas that are also served by reclaimed water systems as defined in
Chapter 62- 610, Part III, F.A.C., shall establish a routine cross-connection control
program to detect and prevent cross-connections that create or may create an imminent
and substantial danger to the public health ..."
The water purveyor is given the authority and responsibility to discontinue service to any
customer who refuses installation of a backflow preventer where an actual and/or a
potential cross-connection may exist under Rule 62-555.360(3), F.A.C. The authority to
control and supervise the installation of approved backflow prevention devices rests with
the "supplier of water or his designated representative..." under Rule 62-555.360(4),
F.A.C.
3.3 Objectives
Backflow may result in the contamination or pollution of the potable water system.
Therefore, it is necessary to establish and maintain a cross-connection control program in
compliance with Rule 62-550.360 to protect the health of the CCUA water system
consumers.
3.4 Retrofit of Existing Facilities
Upon complete examination of the details of specific situations it may be deemed
unreasonable to enforce strict compliance with the specific assembly required for a
specific situation. In such situations, the Executive Director may authorize specific
exceptions to this policy. Items to be considered in making such decisions shall include,
but not be limited to level of hazard, location of meter, practical limitations on the
location of above ground assemblies, practical limitations on the location of below
ground devices, or economic feasibility.
3.5 Ownership and Maintenance
Ownership and maintenance of any residential dual check valve device at the discharge
side of the meter shall be the responsibility of CCUA. The ownership and maintenance of
testable backflow prevention assemblies shall be the responsibility of consumer.
Records and Enforcement
4.1 Responsibility
4.1.1 Water Purveyor Section 4
CCUA is ultimately responsible for the prevention of contamination and pollution of the
public water mains to the extent required by Rule 62-550.360. Such responsibility begins
at the point of origin of the public water supply and ends at the point of connection to the
consumer's service connection. In accordance with the intent of the CCUA's Cross
Connection Control Policy, when required, an approved backflow prevention assembly
shall be installed. The CCUA will designate the location of all backflow prevention
assemblies. Failure, refusal, or inability on the part of the consumer to install a backflow
assembly shall constitute grounds for refusal of water or fire service or the
discontinuance of water or fire service to the premises until such an assembly or
assemblies have been properly installed.
4.1.2 Consumer
The consumer has the primary responsibility of preventing contaminants and pollutants
from entering consumer's water supply system and from entering the CCUA's water
main or water source from consumer's water supply system. The consumer shall protect
its water supply system against actual or potential cross-connection, backflow or
backsiphonage, as required by this policy and other applicable regulations. The consumer
shall be responsible for the testing and maintenance of all testable backflow prevention
assemblies installed on consumer's potable water system.
4.2 Records
Commencing on the effective date of this policy, records concerning testing shall be kept
by the CCUA and shall be accessible for a period of not less than ten (10) years. Testing
information must be documented on approved CCUA testing forms, complete with
original signature, tester certification number, test gauge certification number, meter
number, and meter reading. Test reports shall be submitted to CCUA within ten (10)
days.
4.3 Violations
Submission by any person of any false statement or misrepresentation in any application,
record, report, plan, or other document required by this policy shall constitute a violation
of the conditions for water service. Any person who has not complied with Federal, State,
and Local Laws or Ordinances regarding cross-connection control shall be considered in
violation of the conditions for water service. Any person not complying with the policies
and guidelines within the CCUA's Cross-Connection Control Policy shall be considered
in violation of the conditions for water service.
4.4 Written Notice and Interruption of Service
Notice of the requirement to install and/or repair an approved testable backflow
prevention assembly along with the type and proposed location of the assembly shall be
issued by the Backflow Administrator in writing to the consumer. Upon receipt of such
written notice, the consumer shall have 30 days to install and test the required approved
backflow prevention assembly at the sole expense of the consumer. A final notice via
certified mail to those consumers failing to fully comply, will give an additional seven
days to deliver an acceptable test report to the Backflow Administrator. The consumer's
failure to respond to the second notice will result in discontinuance of their service
immediately after the expiration of the final seven day period and approval by the
CCUA's D&C Superintendent. The service interruption will remain until certified CCUA
staff has inspected and approved the assembly installed by consumer. This interruption of
service will also result in the appropriate service charges being assessed to the account.
This same procedure shall be utilized for the notification and enforcement of the annual
test requirement. In the event that a cross-connection is discovered that presents a serious
contamination threat to CCUA's potable water system, then CCUA shall require the
consumer to immediately remedy the cross-connection and install the prescribed •
backflow assembly in accordance with the provisions of the previous paragraph. The
Executive Director may, at his discretion, have the required backflow assembly installed
at the sole expense of the consumer.
4.5 Enforcement Policy
Water service to a consumer shall be disconnected in accordance with the CCUA's
Cross-Connection Control Policy, if a backflow prevention assembly required by this
policy is not installed, tested, and maintained, or if it is found that a backflow prevention
assembly has been removed, by-passed, or an unprotected cross-connection exists on the
premises with no approved backflow prevention assembly in place. Service shall not be
restored until such conditions or defects are corrected at the consumer's expense.
4.6 Inspections
4.6.1 Proposed Construction
All construction plans for proposed new facilities shall be made available to the CCUA
and reviewed by their engineering and/or cross-connection control departments to
determine the degree of possible cross-connection hazards. At that time, backflow
prevention requirements in accordance with this policy will be initiated.
4.6.2 Authority for Inspection
The Executive Director or duly authorized CCUA employees appointed by the Executive
Director, bearing proper credentials, certification, and identification, shall request
permission to enter upon all properties for the purpose of sampling and testing of the
water, or make inspections and observations of the connections to the public water supply
system. Refusal to allow inspection of any water using equipment, plumbing, or other
cross connections may constitute a violation of this policy and cause the CCUA to
discontinue water service or alternatively to require the consumer to install a testable
backflow prevention assembly where such an installation may not otherwise be required.
4.6.3 Cost
All costs associated with the disconnection or re-connection of utility service as a result
of enforcement action will be paid by the consumer.
4.7 Installation
CCUA engineering, Backflow Administrator, and/or certified distribution and collection
staff shall designate the installation location of an approved backflow prevention
assembly. With regard to above ground backflow assemblies, CCUA staff shall work
with consumers to design the location of meters and such backflow assemblies in areas
where such assemblies can be screened for aesthetic purposes wherever possible. CCUA
recommends multistory buildings which have a number of flushometer toilets or facilities
requiring an uninterrupted source of water, be equipped with parallel assemblies.
Experience has shown that if the water supply is shut off to this type of building,
flushometers may have to be reset manually. In addition, parallel assemblies will allow
backflow prevention assembly repairs without interrupting water service. The parallel
installation permits one assembly to be left on while the other is being tested or serviced.
Usually the two assemblies are sized one size smaller than the service line, (i.e. one 2
inch assembly or two 1 inch assemblies, one 8 inch assembly or two 6 inch assemblies).
4.8 Auxiliary Water Supply
The public water system shall be protected against backflow and back-siphonage by the
installation of an approved backflow prevention assembly if an auxiliary water supply, as
defined herein, is found on the consumer's premises. Such assemblies shall be consistent
with those required for that specific class of customer under this policy unless a specific
cross-connection is found. Should such cross-connection be discovered, the highest
quality backflow prevention assembly, as recommended by CCUA staff, shall then be
required.
Section 5
Reclaimed Water Installation Program
5.1 Effective Date
Thirty (30) days after Board's approval of the policy, for all developments that have not
met the filing requirements of the County's Zoning Department, which requires each new
development to be reviewed by the Development Review Committee (DRC), or for those
developments not requiring DRC approval, which have been quoted charges to connect to
the Clay County Utility Authority's (CCUA) water and/or wastewater systems within
twelve months prior to the effective date of the reclaimed policy. A filing for a DRC
meeting, which is incomplete as of the effective date of this policy, shall not be
considered as filed timely for the prior policy to apply. If the developer has not
commenced substantial construction on his project, which was filed with DRC prior to
the effective date of this policy, within fifteen months after the effective date of the
policy,then said development shall come under the provisions of this policy.
5.2 Applicability
This policy will be applicable to all developments that file for a Development Review
Committee review after the effective date of this policy. This shall include:
5.2.1 Optional
Developments occurring under Development of Regional Impact (DRI) agreements
which may not be technically required to install residential reclaimed, but who choose to
do so in settlement of minor and/or major modifications to the structure and composition
of developments within the DRI. These shall be regulated and charged under this
proposed policy and effective date criteria the same as all other developments.
5.2.2 Exceptions
Exceptions to the applicability of this policy and/or effective date are as follows:
I. Developments occurring under DRI agreements or Florida Quality Development
(FQD) agreements, which are not required by said agreement to install residential
reclaim and who do not volunteer to provide residential reclaimed piping systems.
2. Developments which, as of the date of enactment of this policy, own and maintain
their own reclaimed pumping plant and purchase bulk service from the CCUA.
3. Developments which have prepaid connection fees prior to January 1, 1998, at a
prior approved rate and still have an inventory of prepaid connections, shall be
exempt until such prepaid connections are used up.
4. Developments and/or communities that own, operate and maintain their own
reclaimed infrastructure as of January 1, 1998.
5.3 Developments Required to Install Wastewater Effluent Reclaimed Piping Systems
and Take Reclaimed Water When it is Available
All developments occurring after the effective date of this policy will be reviewed by the
CCUA staff for feasibility of the installation of a reclaimed piping system for irrigation
purposes. These shall include commercial, public facilities, industrial, as well as
residential developments.
5.4 Summary of Criteria to be Utilized by Staff to Evaluate and Determine if Reclaimed
Piping Systems will be Required
1.2.
3.
Financial feasibility of extending a trunk main to an area at that time, or some
planned future date, to provide reclaimed water to the proposed reclaimed system.
This item shall consider the size of the development, distance to nearest master
planned reclaimed trunk main or planned reclaimed plant, remaining developable
property in the area, complexity of existing development of area which trunk
mains must pass through, natural geographical barriers (or obstacles),
environmental damage, etc.
Remaining developable land in the area (new area with very little existing
development and much growth potential will be considered more feasible than an
already built-out area).
Availability of adequate reclaimed water within a reasonable time to service the
reclaimed system.
4. CCUA's budgetary restraints.
5. Length of time before a reclaimed plant or pump station is expected to be built in
the area.
5.5 Surcharge for Developments not required to Install Reclaimed Piping Systems
Due to the built-out condition of certain geographical areas and the other evaluation of
feasibility considerations noted above, it will not be practical to require all areas to install
reclaimed piping systems. All developments that are not required to install the reclaimed
system shall pay a surcharge per ERC as its share of the burden of the reclaimed system
installations at a rate set forth in the "proposed charges for service availability".
5.6 Responsibility for Design and Installation of Reclaimed Piping Systems
Where reclaimed piping systems are required, the design engineer for the project shall
design, at Developer's expense, the reclaimed piping system for the development and any
reasonable trunk mains necessary to connect to the nearest source of reclaimed water, and
developer shall install said system at its expense. The CCUA's existing policy regarding
cost sharing for oversized mains, refundable agreements, plan review and approval, and
adherence to CCUA's specifications and details, shall apply to these reclaimed piping
systems, the same as the potable water distribution systems and wastewater collection
systems.
5.6.1 Design Requirements
All reclaimed water systems shall be designed and constructed in accordance with
Chapter 62-610, F.A.C. The CCUA in its criteria for the construction of reclaimed water
systems shall, as a minimum, include those requirements specified in Chapter 62-610. If
the criteria are found to be in conflict or less restrictive than the provisions of Chapter 62-
610, then the provisions of Chapter 62-610 shall prevail and govern the design and
construction of reclaimed water systems owned and operated by the CCUA. Specifically,
these requirements shall include, as a minimum, the following items:
1. Cross Connection Control
The cross-connection of reclaimed water systems with any potable water system
is specifically prohibited (ref. Rule 62-610.469(7)(a), F.A.C.).
A residential dual check valve device shall be installed on any potable water line
serving residential property that is also served by reclaimed water.
2. Setback and Separation of Facilities
Reclaimed water application systems will not be considered or permitted within
75 feet of an existing or future Florida Department of Environmental
Protection/Florida Department of Health and Rehabilitative Services permitted
potable water supply well (ref. Rule 62-610.471 (3), F.A.C.).
A minimum horizontal separation of five (5) feet (center to center) or three (3)
feet (outside to outside) shall be maintained between reclaimed water mains and
potable water mains or sewage collection and transmission lines (ref. Rule 62-
610.469 (7)(c), F.A.C.).
Minimum vertical separations between reclaimed water mains, potable water
mains, and wastewater collection and transmission mains shall be maintained in
accordance with Rule 62-604.400(g)—(j), F.A.C.
It shall be the consumer's responsibility to utilize low trajectory spray heads or
methods approved by Florida Department of Environmental Protection for all
reclaimed water irrigation systems located within 100 feet of public eating,
drinking, or bathing facilities.
It shall be the consumer's responsibility to construct and operate their reclaimed
water irrigation system so as to minimize over-spray onto impervious surfaces.
Rotor heads must NOT spray across sidewalks.
3. Signage and Coding
Developers of subdivisions and commercial sites installing reclaimed water
systems shall be required to provide public notice signs at entrances and other
strategic areas identifying the area as a reclaimed water use area. Consumers of
reclaimed water for non-irrigation purposes shall provide similar notification
signage at the point of reclaimed water use (ref. Rule 62-610.468, F.A.C.).
All reclaimed water transmission mains shall be color coded, marked with marker
tape and/or labeled to specifically identify said piping as reclaimed water mains.
Marker tape in lieu of colored pipe shall only be allowed in situations where
colored pipe is not reasonably available. Approval of such variance by the
Executive Director shall only occur on a case by case basis after examination of
the facts of each situation. The requirement for reclaimed water systems in new
subdivisions shall be governed by CCUA's Reclaimed Policy.
4. Prohibited Uses
Reclaimed water shall not be connected to the on-site potable water plumbing.
There shall not be any above ground hose bibb connections to the reclaimed water
system. All reclaimed flushing devices must be located in below grade, locked
vaults clearly labeled as being non-potable.
Reclaimed water shall not be used to fill swimming pools, hot tubs, wading pools,
spas, or similar facilities.
Use of reclaimed water for any purpose other than those allowed by Chapter 62-
610 F.A.C. is prohibited.
5. Other Uses
Reclaimed water shall not be designated as the source for fire protection without a
specific, independent agreement between the Executive Director and the
applicant. Said agreement shall include verification of compliance with the
provisions of the F.A.C.
5.6.2 Installation Requirements
Main lines for reclaimed water shall be SDR21/Class 200 PVC. The pipe shall be
Pantone purple 522C in color. All valve boxes for reclaimed water shall have the words
"Reuse" or "Reclaimed" in raised lettering on the outside top and be painted Pantone
purple 522C. All installations of reclaimed water systems shall be in accordance with
CCUA's standard specifications, details, and approved materials.
5.7 Wells
All developments where reclaimed piping systems are installed shall prohibit the
installation of wells for irrigation purposes.
5.8 Requirement for Reclaimed Meter
All customer classes that have reclaimed piping systems available shall pay for the
installation of a reclaimed meter at the same time the domestic meter is requested.
5.9 Approval of Reclaimed Water Irrigation System Contractors
It is deemed by CCUA to be important that reclaimed water irrigation system contractors,
be thoroughly educated with regard to reclaimed water and their systems in an effort to
eliminate any potential cross connection with the potable water system. In this regard, all
irrigation contractors installing or maintaining irrigation systems in conjunction with this
reclaimed program must pre-qualify with CCUA by passing a qualification interview
with CCUA's staff for the purpose of demonstrating knowledge of the key issues
regarding use of reclaimed water. The reclaimed irrigation system contractor
qualification criteria stated herein shall apply to all contractors that install, modify, or
repair reclaimed water irrigation systems within CCUA's service area.
I. All contractors shall register in person with an authorized representative of
CCUA. All contractors shall provide a current copy of their certificate of
competency for installation of an irrigation system issued by the Clay County
Building Department or a copy of their master plumber's license.
2. All contractors shall provide documentation that names CCUA as an additional
insured on their comprehensive general liability insurance policy. Minimum
coverage shall be $500,000 per occurrence, $1,000,000 aggregate.
Note: The contractor must obtain a permit from the Clay County Building
Department to install an irrigation system. In order to receive this permit, the
contractor must be registered with CCUA.
5.10 Requirement for Installation of an Automatic Sprinkler System
All developments where reclaimed piping systems are required shall install or require to
be installed an automatic sprinkler irrigation system acceptable to CCUA for the
development of each separate parcel (lot) within the development. All reclaimed water
irrigation systems shall be permanent, in-ground systems. For identification purposes,
each on-site reclaimed irrigation system shall be constructed with color-coded pipe.
Reclaimed irrigation piping shall be a purple color (Pantone purple, 522C) per
requirements of the F.A.C.
1. Rain sensors shall be incorporated into each irrigation system. These rain sensors
shall prevent the irrigation system from operating when soil moisture is adequate
for healthy lawns and landscaping without additional watering.
2. Each reclaimed irrigation system shall include an automatic control function. This
control feature will allow the homeowner to program the frequency and duration
of each zone within the irrigation system.
3. The use of hose bibbs on any reclaimed water irrigation system is strictly
forbidden. Under no circumstances shall hose bibbs be installed on irrigation
systems using reclaimed water(see F.A.C. 62-610.469 (3).
4. The irrigation system shall be designed so that all the pervious area within the
property is irrigated. No surface water run off is allowed into any storm water
swale, drain, ditch, or roadway. Installation of low trajectory nozzles around
swimming pools is recommended to reduce aerosol formations.
5.11 Requirement for Payment of Reclaimed Base Facility Charge
All customer classes that have reclaimed piping systems available shall be required to
pay the Base Facility Charge for reclaimed water whether they use the reclaimed water or
not.
5.12 Activation
All reclaimed water connections will be tested by certified CCUA staff to verify the
absence of a cross connection. All newly installed reclaimed water connections must pass
a cross connection inspection prior to the initial activation. Applicants for reclaimed
water service must pass a cross connection inspection, as performed by certified CCUA
staff, prior to activation. A satisfactory cross connection inspection is required every time
there is a 'turn on' of service requested at an address. An inspection is also required after
all modifications to any reclaimed irrigation system. All residential sites receiving
reclaimed water must have a residential backflow prevention device on the incoming
potable water supply line per the requirements of CCUA's Cross-Connection Control
Policy.
1. Inspection Procedures:
To run a cross-connection check on a system that has reclaimed water, the
following procedures need to be followed:
A.B.
C.
D.
Check the ph and chlorine residual at the hose bibb, then shut off the
potable water system at the meter.
Open a hose bibb on the building that is connected to the potable system
and relieve the pressure on the system.
Attach a pressure gauge to the hose bibb.
Open the hose bibb and observe there is no pressure on the system.
E. Leaving the hose bibb open and the potable meter shut off, the reclaimed
sprinkler system is exercised one zone at a time through its electrical
timing device. The gauge is monitored to make sure no change in pressure
has occurred. (If the inspection is with an irrigation contractor/plumber
and no electricity is available, the inspection will be conducted manually
through the control valves.)
F. If the test proves to be acceptable, the cross-connection test is approved
and signed off, and the potable system is placed back in service. If
pressure is observed, the potable system is locked off. The cross-
connection is removed. Disinfection is introduced to the system for 24
hours at 50 ppm. The system is then flushed and sampled for two
consecutive days. If satisfactory results are received from the samples, the
service is then unlocked and placed in service. If unsatisfactory results are
received, samples are re-taken until two consecutive days of satisfactory
results are achieved.
Note: This cross connection inspection is performed each time an application is received
in new or existing service areas that are providing reclaimed water to residential and/or
commercial customers.
Approval for activation shall be given only after all inspection items have been
completed and approved in writing by certified CCUA staff.
5.13 Deactivation
All customer classes that have reclaimed irrigation systems are subject to the provisions
and restrictions contained within this policy. Any violations of this policy may result in
the discontinuance of reclaimed water service; such violations may include unauthorized
irrigation system alterations, cross connections with potable water, or anything that may
endanger public health or damage the reclaimed supply system. Deactivated reclaimed
water service will not be restored to a customer until the violation has been corrected and
a satisfactory cross connection inspection has been completed.
5.14 Charges for Service Availability

(1)Cross-connections, as defined in Rule 62-550.200, F.A.C., are prohibited unless appropriate backflow protection is provided
to prevent backflow through the cross-connection into the public water system. This does not prohibit a public water system from
being interconnected to another public water system of the same type without backflow protection (i.e., a community water system
[CWS] may be interconnected to another CWS without backflow protection, a non-transient non-community water system
[NTNCWS] may be interconnected to another NTNCWS without backflow protection,and a transient non-community water system
[TWS] may be interconnected to another TWS without backflow protection).
(a) Appropriate backflow protection for various applications is described in Recommended Practice for Backflow Prevention
and Cross-Connection Control: AWWA Manual M14, Third Edition, as clarified and modified in paragraphs(b) and(c), below, and
in Table 62-555.360-2, which appears at the end of this section. The third edition of AWWA Manual M14 is incorporated herein by
reference; is available from the American Water Works Association, 6666 West Quincy Avenue, Denver, CO 80235,
www.awwa.org; and is available for review at the Department of Environmental Protection, Source and Drinking Water Program,
MS 3520, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, at the Department of Environmental Protection district offices,
and at the Approved County Health Departments.
(b) Except for the temporary cross-connections described in paragraph (c), below, cross-connections between a public water
system and a wastewater system or reclaimed water system are prohibited (i.e., an air gap shall be maintained between any public
water system and any wastewater system or reclaimed water system). The Department shall allow an exception to this requirement if
the supplier of water provides justification for the exception and provides alternative backflow protection that achieves a level of
reliability and public health protection similar to that achieved by an air gap (e.g., two biannually-tested reduced-pressure principle
assemblies installed in series); however, in no case shall the Department allow a single, annually-tested mechanical backflow
preventer to be used as the only protection against backflow of wastewater or reclaimed water into a public water system.
(c) Temporary cross-connections may be made between a public water system and a wastewater system or reclaimed water
system for either of the following purposes:
1. To supply water for flushing or testing a new wastewater force main or new reclaimed water main, in which case a double
check valve assembly or reduced-pressure principle assembly shall be provided at the cross-connection.
2. To supply water for temporarily operating a new reclaimed water main that has not yet been connected to a reclaimed water
supply, in which case a reduced-pressure principle assembly shall be provided at the cross-connection.
(2) Each community water system (CWS) shall establish and implement a cross-connection control program utilizing backflow
protection at or for service connections from the CWS in order to protect the CWS from contamination caused by cross-connections
on customers' premises. This program shall include a written plan that is developed using recommended practices of the American
Water Works Association set forth in Recommended Practice for Backflow Prevention and Cross-Connection Control: AWWA
Manual M14, Third Edition, as clarified and modified in paragraph (a), below. The third edition of AWWA Manual M14 is
incorporated herein by reference and is available as indicated in paragraph 62-555.360(1)(a), F.A.C.
(a) The minimum components that each CWS shall include in its written cross-connection control plan are listed and described
in Table 62-555.360-1, which appears at the end of this section. The categories of customers for which each CWS shall ensure
backflow protection is provided at or for the service connection from the CWS to the customer are listed in Table 62-555.360-2,
which appears at the end of this section.
(b)Each CWS serving more than 10,000 persons shall prepare and submit cross-connection control program annual reports. The
first annual report shall cover calendar year 2016, and subsequent annual reports shall cover each calendar year thereafter. These
reports shall be prepared using Form 62-555.900(13), Cross-Connection Control Program Annual Report, effective 5-5-14, which is
incorporated herein by reference and which is available as described in Rule 62-555.900, F.A.C., and at
http://www.nrules.orgiGateway'reference.asp?No—Ref-04104. These reports shall be submitted to the appropriate Department of
Environmental Protection district office or Approved County Health Department within three months after the end of the calendar
year covered by the report.
(3) Upon discovery of a prohibited or inappropriately protected cross-connection, public water systems either shall ensure that
the cross-connection is eliminated, shall ensure that appropriate backflow protection is installed to prevent backflow into the public
water system, or shall discontinue water service. If the discovered cross-connection is on the premises of a customer of a community
water system (CWS) and if the customer's premises is in a category described in Table 62-555.360-2, which appears at the end of
this section, the CWS shall ensure that appropriate backflow protection is provided at or for the water service connection to the
customer regardless of whether the cross-connection is eliminated or whether internal backflow protection is installed at the cross-
connection to the customer's plumbing system.

2 The CWS shall determine the degree of hazard."Low hazard"or"non-health hazard" and"high hazard"or"health hazard"are
defined in AWWA Manual M14 as incorporated in paragraph 62-555.360(l)(a),and subsection 62-555.360(2), F.A.C.
3 A DC may be provided if it was installed before 5-5-14; and if such a DC is replaced on or after 5-5-14, it may be replaced
with another DC.
4 For the purpose of this table,"auxiliary water system"means a pressurized system of piping and appurtenances using auxiliary
water, which is water other than the potable water being supplied by the CWS and which includes water from any natural source
such as a well, pond, lake, spring, stream, river, etc., includes reclaimed water, and includes other used water or industrial fluids
described in AWWA Manual M14 as incorporated in paragraph 62-555.360(1)(a), and subsection 62-555.360(2), F.A.C.; however,
"auxiliary water system" specifically excludes any water recirculation or treatment system for a swimming pool, hot tub, or spa.
(Note that reclaimed water is a specific type of auxiliary water and a reclaimed water system is a specific type of auxiliary water
system.)
The Department shall allow an exception to the requirement for backflow protection at or for a residential or non-residential
service connection from a CWS to premises where there is an auxiliary or reclaimed water system if all of the following conditions
are met:
• The CWS is distributing water only to land owned by the owner of the CWS.
• The owner of the CWS is also the owner of the entire auxiliary or reclaimed water system up to the points of auxiliary or
reclaimed water use.
• The CWS conducts at least biennial inspections of the CWS and the entire auxiliary or reclaimed water system to detect and
eliminate any cross-connections between the two systems.
6 For the purpose of this table,"residential service connection"means any service connection, including any dedicated irrigation
or fire service connection, that is two inches or less in diameter and that supplies water to a building, or premises, containing only
dwelling units; and"non-residential service connection"means any other service connection.
A DuC may be provided only if there is no known cross-connection between the plumbing system and the auxiliary or
reclaimed water system on the customer's premises. Upon discovery of any cross-connection between the plumbing system and any
reclaimed water system on the customer's premises, the CWS shall ensure that the cross-connection is eliminated. Upon discovery
of any cross-connection between the plumbing system and any auxiliary water system other than a reclaimed water system on the
customer's premises, the CWS shall ensure that the cross-connection is eliminated or shall ensure that the backflow protection
provided at or for the service connection is equal to that required at or for a non-residential service connection.
8 Reclaimed water regulated under Part III of Chapter 62-610, F.A.C., is a low hazard unless it is stored with surface water in a
pond that is part of a stormwater management system, in which case it is a high hazard;well water is a low hazard unless determined
otherwise by the CWS; industrial fluids and used water other than reclaimed water are high hazards unless determined otherwise by
the CWS;reclaimed water not regulated under Part III of Chapter 62-610, F.A.C.,and surface water are high hazards.
9 Upon discovery of any cross-connection between the plumbing system and any reclaimed water system on the customer's
premises,the CWS shall ensure that the cross-connection is eliminated.
10 A DC may be provided if both of the following conditions are met:
• The dedicated irrigation service connection initially was constructed before 5-5-14.
• No chemicals are fed into the irrigation system.
" The CWS may rely on the internal backflow protection required under the Florida Building Code or the predecessor State
plumbing code. The CWS may, but is not required to, ensure that such internal backflow protection is inspected/tested and
maintained the same as backflow protection provided at or for service connections from the CWS.
12 The Department shall allow an exception to the requirement for backflow protection at or for a residential or non-residential
dedicated fire service connection from a CWS to a wet-pipe sprinkler, or wet standpipe, fire protection system if both of the
following conditions are met:
• The fire protection system was installed and last altered before 5-5-14.
• The fire protection system contains no chemical additives and is not connected to an auxiliary water system as defined in
Footnote 4.
13 Upon discovery of any cross-connection between the fire protection system and any reclaimed water system on the
customer's premises,the CWS shall ensure that the cross-connection is eliminated.
14 The CWS shall ensure that backflow protection commensurate with the degree of hazard is provided at or for the service
connection from its fire hydrant.
