FLORIDA BUILDING CODE — PLUMBING, 6th EDITION (2017) 155

APPENDIX F

PROPOSED CONSTRUCTION BUILDING CODES FOR

TURF AND LANDSCAPE IRRIGATION SYSTEMS

PART 1: GENERAL

A. Description.

1. Purpose. To establish uniform minimum standards

and requirements for the design and installation of

safe, cost effective, reliable irrigation systems for

turf and landscape areas which promote the effi-

cient use and protection of water and other natural

resources.

2. Definition. Turf and landscape irrigation systems

apply water by means of permanent above-ground

or subsurface sprinkler or microsprinkler equip-

ment under pressure.

3. Scope. These construction codes shall apply to all

irrigation systems used on residential and commer-

cial landscape areas. They address the design

requirements, water quality, materials, installation,

inspection, and testing for such systems. These con-

struction codes do not apply to irrigation systems

for golf courses, nurseries, greenhouses, or agricul-

tural production systems.

4. Application. All new irrigation systems and any

new work to existing irrigation systems shall con-

form to the requirements of this code.

5. Application to existing irrigation installations.

Nothing contained in this code shall be deemed to

require any irrigation system or part thereof, which

existed prior to the establishment of this code, to be

changed, altered or modified to meet the standards

of this code.

B. Permits.

1. Permits required. It shall be unlawful to construct,

enlarge, alter, modify, repair, or move any irriga-

tion system or part thereof, or to install or alter any

equipment for which provision is made or the

installation of which is regulated by this code with-

out first having filed application and obtained a per-

mit therefore from the building official. A permit

shall be deemed issued when signed by the building

official and impressed with the seal of the govern-

mental agency issuing said permit.

2. Exceptions. All work where exempt from permit

shall still be required to comply with the code. No

permit shall be required for general maintenance or

repairs which do not change the structure or alter

the system and the value of which does not exceed

$600.00 in labor and material based on invoice

value.

C. Preconstruction submittals.

1. Plans or drawings.

. S

le-family residence. Provide design draw-ings or

shop drawings, where required, for the installation prior to

start of construction. Design drawings shall be clearly

readable, to reasonable scale, show the entire site to be

irrigated, and include all improvements. Drawings can be

pre-pared by a properly licensed qualified contractor.

b. Commercial, industrial, municipal and multi-ple-family.

Provide professionally designed drawings prior to start

of construction. Design drawings shall be clearly readable,

to reasonable scale, show the entire site to be irrigated,

includ-ing all improvements, and shall include but not be

limited to: date, scale, revisions, legend, speci-fications which

list all aspects of equipment and assembly there of, water

source, water meter and/or point of connection, backflow

prevention devices, pump station size, pump station location,

design operating pressure and flow rate per zone, precipitation

rate per zone, locations of pipe, con-trollers, valves,

sprinklers, sleeves, gate valves, etc. The plans and

specifications shall be pre-pared in accordance with Section

107 of the Flor-ida Building Code, Building.

c. Sprinkler layout. Sprinkler layout may be modified to adjust

for field conditions provided it complies with part VI, Section

B, subsection 1 Sprinkler layout and spacing. Prior to final

inspection, the contractor shall submit a letter or as-built

drawing that reflects the modification to the authority with

jurisdiction.

D. Definitions.

ABS Pipe. Acrylonitrile-butadiene-styrene black,

semi-rigid, plastic pipe extruded to IPS. ABS pipe is in

limited use in present day irrigation systems. Solvent

weld fittings are used with this pipe (see ASTM

D1788).

Air Release Valve. A valve which will automatically

release to the atmosphere accumulated small pockets of

air from a pressurized pipeline. A small orifice is used

to release air at low flow rates. Air release valves are

normally required at all summits of mainline and sub-

main pipelines in an irrigation system.

Anti-Siphon Device. A safety device used to prevent

back-flow of irrigation water to the water source by

ack-siphonage.

Application Rate. The average rate at which water is

applied by an irrigation system, sometimes also called

precipitation rate. Units are typically inches/hr or mm/

hr.

Application Uniformity. Irrigation application unifor-

mity (also known as distribution uniformity) describes

how evenly water is distributed within an irrigation

zone.

Arc. The angle of coverage of a sprinkler in degrees

from one side of throw to the other. A 90-degree arc

would be a quarter-circle sprinkler.

Adopted: October 12, 2017

Effective: January 1, 2018

APPENDIX F

156

Atmospheric Vacuum Breaker. An anti-siphon

device which uses a floating seat to direct water flow.

Water draining back from irrigation lines is directed to

the atmosphere to protect the potable water supply.

Automatic Control Valve. A valve in a sprinkler sys-

tem which is activated by an automatic controller by

way of hydraulic or electrical control lines and controls

a single device or multiple devices.

Automatic System. An irrigation system which oper-

ates following a preset program entered into an auto-

matic controller.

Backflow Prevention Device. An approved safety

device used to prevent pollution or contamination of

the irrigation water supply due to backflow from the

irrigation system.

Belled (Pipe). Pipe which is enlarged at one end so that

the spigot end of another length of pipe can be inserted

into it during the assembly of a pipeline.

Block (of sprinklers). A group of sprinklers controlled

by one valve. Also called zones or subunits.

Block System. An irrigation system in which several

groups of sprinklers are controlled by one valve for

each group.

Bubbler Irrigation. The application of water to the

soil surface or a container as a small stream or fountain.

Bubbler emitter discharge rates are greater than the 0.5

to 2 gph characteristic of drip emitters, but generally

less than 60 gph.

Check Valve. A valve which permits water to flow in

one direction only.

Chemical Water Treatment. The addition of chemi-

cals to water to make it acceptable for use in irrigation

systems

Chemigation. The application of water soluble chemi-

cals by mixing or injecting with the water applied

through an irrigation system.

Contractor. Any person who engages in the fabrica-

tion and installation of any type of irrigation system on

a contractual basis in accordance with all stipulations

receiving his compensation.

Control Lines. Hydraulic or electrical lines which

carry signals (to open and close the valves) from the

controller to the automatic valves.

Controller. The timing mechanism and its mounting

box. The controller signals the automatic valves to

open and close on a pre-set program or based on sensor

readings.

Coverage. Refers to the way water is applied to an

area.

Cycle. Refers to one complete run of a controller

through all programmed controller stations.

Demand (or irrigation demand). Refers to the irriga-

tion requirements of the irrigated area. Demand primar-

ily depends on the type of crop, stage of growth, and

climatic factors.

Design Area. The specific land area to which water is

to be applied by an irrigation system.

Design Emission Uniformity. An estimate of the uni-

formity of water application with an irrigation system.

Design Pressure. The pressure at which the irrigation

system or certain components are designed to operate.

The irrigation system design pressure is that measured

at the pump discharge or entrance to the system if there

is no pump, and a zone design pressure is the average

operating pressure of all emitters within that zone.

Direct Burial Wire. Plastic-coated single-strand cop-

per wire for use as control line for electric valves.

Discharge Rate. The instantaneous flow rate of an

individual sprinkler, emitter, or other water emitting

device, or a unit length of line-source microirrigation

tubing. Also, the flow rate from a pumping system.

Double Check Valve. An approved assembly of two

single, independently-acting check valves with test

ports to permit independent testing of each check valve.

Drain Valve. A valve used to drain water from a line.

The valve may be manually or automatically operated.

Drip

Irrigatio

n. The precise low-rate application of

water to or beneath the soil surface near or directly into

the plant root zone. Applications normally occur as

small streams, discrete or continuous drops, in the

range of 0.5 to 2.0 gph.

Effluent water. Also referred to as reclaimed or gray

water is wastewater which has been treated per Florida

Statute, §403.086 and is suitable for use as a water sup-

ply for irrigation systems.

Emitters. Devices which are used to control the dis-

charge of irrigation water from lateral pipes. This term

is primarily used to refer to the low flow rate devices

used in microirrigation systems.

Fertigation. The application of soluble fertilizers with

the water applied through an irrigation system.

Filtration System. The assembly of physical compo-

nents used to remove suspended solids from irrigation

water. These include both pressure and gravity type

devices, such as settling basins, screens, media filters,

and centrifugal force units (vortex sand separators).

Flexible Swing Joint. A flexible connection between

the lateral pipe and the sprinkler which allows the

sprinkler to move when force is applied to it.

Flow Meters. Devices used to measure the volume of

flow of water (typically in gallons), or flow rates (typi-

cally in gpm), and to provide data on system usage.

Gauge (Wire). Standard specification for wire size.

The larger the gauge number, the smaller the wire

diameter.

Head. A sprinkler head. Sometimes used interchange-

ably with and in conjunction with “Sprinkler.”

thrust blocks in accordance with ASAE S-376.1.

 The trench bottom must be uniform, free of debris, and

of sufficient width to properly place pipe and support

it over its entire length. Native excavated material may

be used to backfill the pipe trench. However, the

initial backfill material to 6" above the top of the pipe

shall be free from rocks or stones larger than 1-inch in

diameter. The final backfill material shall be free of

rock or debris that is greater than 3" in diameter. At the

time of placement, the moisture content of the material

shall be such that the required degree of compaction

can be obtained with the backfill method to be used.

Blocking or mounding shall not be used to bring the

pipe to final grade.

6. Pipe sleeves must be used to protect pipes or wires

installed under pavement o

r roadways.

when

position

of irrigation pipes or wires conflict with pipes or

appurtenances of other trades.

Use pipe sleeves two pipe

sizes larger than the carrier pipe or twice the d

iameter of

the wire bundle to be placed under the paving or

roadway and extending a mini-mum of 3 feet beyond

the paved area or as required by the Florida Department

of Transportation (FDOT). Use sleeve pipe with wall

thickness at least equal to the thickness of Schedule 40

or PR 160 pipe, whichever is

thicker. Proper backfill

and compaction procedures should be followed.

B. Control valve installation.

proper operation and maintenance. Where valves

are installed underground, they shall be provided

with a valve box with cover extending from grade

to the body of the valve. The top of the valve body

should have a minimum of 6 inches (152 mm) of

cover in nontraffic and noncultivated areas and 18

inches (457 mm) of cover in traffic areas. The valve

box shall be installed so as to minimize the effect of

soil intrusion within the valve box with the use of

filter fabric, pea gravel, or other acceptable

material. If an automatic valve is installed under

each sprinkler, then the valve box may be omitted.

2. Install valve boxes so that they do not rest on the

pipe, the box cover does not conflict with the valve

stem or interfere with valve operation, they are

flush with the ground surface and do not present a

tripping hazard or interfere with routine mainte-

nance of the landscape.

3. Install quick coupling valves on swing joints or

flexible pipe with the top of the valve at ground

level.

4. Any above-ground manually-operated valves on

nonpotable water systems will be adequately identi-

fied with distinctive purple colored paint. Do not

provide hose connections on irrigation systems that

utilize nonpotable water supplies.

C. Sprinkler installation.

1. On flat landscaped areas, install sprinklers plumb.

In areas where they are installed on slopes, sprin-

klers may be tilted as required to prevent erosion.

inches) to secure the tubing and prevent it from

moving through the mulch bed.

D. Pump installation.

1. Install pumps as per the manufacturer’s recommen-

dations. Set pumps plumb and secure to a firm con-

crete base. There should be no strain or distortion

on the pipe and fittings. Pipe and fittings should be

supported to avoid placing undue strain on the

pump. Steel pipe should be used on pumps 5 horse-

power (hp) or larger whenever practical.

2. Pumps must be installed in a manner to avoid loss

of prime. Install suction line to prevent the accumu-

lation of air pockets. All connections and reductions

in suction pipe sizes should be designed to avoid

causing air pockets and cavitation.

3. Pumps must be located to facilitate service and ease

of removal. Appropriate fittings should be provided

to allow the pump to readily be primed, serviced,

and disconnected. Provide an enclosure of adequate

size and strength, with proper ventilation, to protect

the pump from the elements (except residential sys-

tems).

E. Low voltage wire installation.

1. Install low voltage wire (less than 98 volts) with a

minimum depth of cover of 12 inches (305 mm)

where not installed directly under the mainline.

2. Provide a sufficient length of wire at each connec-

tion to allow for thermal expansion/shrinkage.

3. As a minimum, provide a 12-inch (305 mm) diame-

ter loop at all splices and connections.

4. Terminations at valves will have 24-inches (610

mm) minimum free wire.

5. Install all above-ground wire runs and wire entries

into buildings in electrical conduit.

Exception: No conduit is required when wiring

above ground manifolds from the valve to the

ground immediately beneath it.

6. Provide common wires with a different color than

the power wires (white shall be used for common

wires).

7. Connections are to be made using UL approved

devices specifically designed for direct burial.

8. All splices shall be enclosed within a valve box.

F. Hydraulic control tubing.

1. For hydraulic control systems, use a water supply

that is filtered and free of deleterious materials, as

defined by the hydraulic control system manufac-

turer. Install a backflow prevention device where

the hydraulic control system is connected to potable

water supplies.

2. Install tubing in trenches freely and spaced so that it

will not rub against pipe, fittings, or other objects

that could score the tubing, and with a minimum

12-inch (305 mm) diameter loop at all turns and

connections. Provide a minimum depth of cover of

12 inches (305 mm).

3. Connect tubing with couplings and collars recom-

mended by the tubing manufacturer. All splices

shall be made in valve boxes. Prefill tubing with

water, expelling entrapped air and testing for leaks

prior to installation.

Install exposed tubing in a protective conduit manu-

factured from Schedule 40 UV protected PVC or elec-

trical conduit.

PART VI: TESTING & INSPECTIONS

A. Purpose. All materials and installations covered by the

Irrigation Code shall be inspected by the governing

agency to verify compliance wi

th the I

rrigation Code.

B. Rough inspections. Rough inspections will be per-

formed throughout the duration of the installation.

These inspections will be made by the governing

agency to ensure that the installation is in compliance

with the design intent, specifications, and the Irrigation

Codes. Inspections will be made on the following items

at the discretion of the governing agency:

1. Sprinkler layout and spacing: This inspection will

verify that the irrigation system design is accurately

installed in the field. It will also provide for alter-

ation or modification of the system to meet field

conditions. To pass this inspection, sprinkler/emit-

ter spacing should be within ± 5 percent of the

design spacing.

APPENDIX F

164

2. Pipe installation depth: All pipes in the system shall be

installed to depths as previously described in this code.

3. Test all

mainlines upstream of the zone valves as

follows:

a. Fill the completely installed pipeline slowly with

water to expel air. Allow the pipe to sit full of

water for 24 hours to dissolve remaining trapped

air.

b. Using a metering pump, elevate the water pres-

sure to the maximum static supply pressure

expected and hold there for a period of 2 hours,

solvent-weld pipe connections shall have no leak-

age.

c. For gasketed pipe main lines add water as needed to

maintain the pressure. Record the amount of water

added to the system over the 2-hour period.

d. Use the following formulas to determine the

maximum allowable leakage limit of gasketed

pipe.

DUCTILE IRON:

PVC, GASKETED JOINT:

Where:

L = allo

wable leakage (gph),

N = number of joints,

D = nominal diameter of pipe (inches), P

= average test pressure (psi), and

S = length of pipe (fi).

e. When testing a system which contains metal-

seated valves, an additional leakage per closed valve

f 0.078 gph/inch of nominal valve size is allowed.

C. Final inspection. When the work is complete th

e con-

tractor shall request a final inspection.

1. Cross connection control and backflow prevention.

a. Public or domestic water systems: Check that an

approved backflow prevention assembly is prop-

erly installed and functioning correctly. Review

the location of the assembly to check that it is not

creating a hazard to pedestrians or vehicular traf-fic.

b. Water systems other than public or domestic

water systems: Check that the proper backflow

prevention assemblies are provided.

c. All assemblies that can be, will

be tested by a

technician certified for backflow testing by a

State recognized certifying board prior to being

placed into service.

2. Sprinkler coverage testing.

a. All sprinklers must be adjusted to minimize over-

spray onto buildings and paved areas. Minor tol-

erances shall be made to allow for prevailing

winds.

b. All sprinkler controls must be adjusted to mini-

mize runoff of irrigated water. Water application

rates shall not exceed the absorption rate of the

soil.

c. All sprinklers must operate at their design radius

of throw. Nozzle sizes and types called for in the

system design must have been used. All nozzles

within the same zone shall have matched precipi-

tation rates unless otherwise directed in order to

increase efficiency by adjusting the nozzle selec-

tion to match site conditions.

d. Spray patterns must overlap as designed (a.k.a.

head to head coverage) or placed to achieve the

highest possible distribution uniformity using the

manufacturer’s specifications.
