(2)     An irrigation system used on or by an agricultural operation as defined by Agriculture Code Section 251.002.

Sec. 3.11.003     Irrigation system design, installation and operation

Within the City and its extraterritorial jurisdiction, all irrigation systems shall be designed, installed, maintained and operated in accordance with Texas Commission on Environmental Quality (TCEQ) rules adopted under Title 30 Texas Administrative Code Chapter 344, rules for landscape irrigation, said rules, as amended, being adopted by reference and incorporated for all purposes herein.

Sec. 3.11.004  Backflow Prevention Methods and Devices

a               Any irrigation system that is connected to the potable water supply must be connected through a backflow prevention method approved by the TCEQ. The backflow prevention device must be approved by the American Society of Sanitary Engineers; or the Foundation for Cross-Connection Control and Hydraulic Research, University of Southern California; or any other laboratory that has equivalent capabilities for both the laboratory and field evaluation of backflow prevention assemblies. The backflow prevention device must be installed in accordance with the laboratory approval standards or if the approval does not include specific installation information, the manufacturer's current published recommendations.

 

(b)        If conditions that present a health hazard exist, one of the following methods must be used to prevent backflow: 

(1) An air gap may be used if: 

(A) there is an unobstructed physical separation; and

(B) the distance from the lowest point of the water supply outlet to the flood rim of the fixture or assembly into which the outlet discharges is at least one inch or twice the diameter of the water supply outlet, whichever is greater. 

 

(2) Reduced pressure principle backflow prevention assemblies may be used if: 

 

A              the assembly is installed with the termination point a minimum of twelve (12) inches above finished grade in a location that will ensure that the assembly will not become submerged; and 

 

(B) drainage is provided for any water that may be discharged through the assembly relief valve. 

(3) Pressure vacuum breakers may be used if: 

(A) no back-pressure condition will occur; and

(B) the device is installed at a minimum of 12 inches above any downstream piping and the highest downstream opening.  Pop-up sprinklers are measured from the retracted position from the top of the sprinkler.

(4) Atmospheric vacuum breakers may be used if: 

(A) no back-pressure will be present;

(B) there are no shutoff valves downstream from the atmospheric vacuum breaker;

(C) the device is installed at a minimum of six inches above any downstream piping and the highest downstream opening. Pop-up sprinklers are measured from the retracted position from the top of the sprinkler;

(D) there is no continuous pressure on the supply side of the atmospheric vacuum breaker for more than 12 hours in any 24-hour period; and 

(E) a separate atmospheric vacuum breaker is installed on the discharge side of each irrigation control valve, between the valve and all the emission devices that the valve controls. 

(c)        Backflow prevention assemblies used in applications designated as health hazards must be tested upon installation and annually thereafter. 

 (d)      If there are no conditions that present a health hazard, double check valve backflow prevention assemblies may be used to prevent backflow if the device is tested upon installation and test cocks are used for testing only.

(e)         If a double check valve is installed below ground: 

(1) test cocks must be plugged, except when the double check valve is being tested;

(2) test cock plugs must be threaded, water-tight, and made of non-ferrous material; 

(3) a y-type strainer is installed on the inlet side of the double check valve; 

(4) there must be a clearance between any fill material and the bottom of the double check valve to allow space for testing and repair; and 

(5) there must be space on the side of the double check valve to test and repair the double check valve.

(6) Double check assemblies must be tested upon installation and every 3 years thereafter. 

(f)        If an existing irrigation system without a backflow-prevention assembly requires major maintenance, alteration, repair, or service, the system must be connected to the potable water supply through an approved, properly installed backflow prevention method before any major maintenance, alteration, repair, or service is performed.

(g)        The irrigator shall ensure the backflow prevention device is tested prior to being placed into service and the test results provided to the local water purveyor and the irrigation system's owner or owner's representative within ten business days of testing of the backflow prevention assembly.

(h)        The City is not responsible for any pressure loss created by the installation of a backflow assembly.

Sec. 3.11.005  Specific Conditions and Cross-Connection Control

a               Before any chemical is added to an irrigation system connected to the potable water supply, the irrigation system must be connected through a reduced pressure principle backflow prevention assembly or air gap. 

 

b               Connection of any auxiliary water supply to an irrigation system that is connected to the potable water supply can only be done if the irrigation system is connected to the potable water supply through a reduced pressure backflow prevention assembly or an air gap separation.

 

c               Irrigation system components with chemical additives induced by aspiration, injection, or emission system connected to any potable water supply must be connected through a reduced pressure principle backflow assembly. 

(d)       If an irrigation system is designed or installed on a property that is served by an onsite sewage facility, as defined in Title 30 Texas Administrative Code Chapter 285, then:

(1) all irrigation piping and valves must meet the separation distances from the On-Site Sewage Facilities system as required for a private water line in Title 30 Texas Administrative Code Section 285.91(10); 

(2) any connections using a private or public potable water source that is not the City’s potable water system must be connected to the water source through a reduced pressure principle backflow prevention assembly as defined in Title 30 Texas Administrative Code Section 344.50; and 

(3) any water from the irrigation system that is applied to the surface of the area utilized by the On-Site Sewage Facility system must be controlled on a separate irrigation zone or zones so as to allow complete control of any irrigation to that area so that there will not be excess water that would prevent the On-Site Sewage Facilities system from operating effectively. 

(e)        Quick couplers or hose connections of any type installed within the irrigation system shall require the proper installation of a reduced pressure backflow prevention assembly. The assembly shall be tested upon installation and annually thereafter.

Sec. 3.11.006     Duties and responsibilities of the city plumbing inspectors
