Bypass type sold moisture irrigation controllers use water content information from the
sensor to either allow or bypass scheduled irrigation cycles on the irrigation timer. The
threshold value of soil water content is set by the user.
Another type of control technique with SMS devices is on-demand where controller
initiated irrigation is done at low threshold and terminates irrigation at high threshold.
Smart Irrigation Controller - ANSWER * Available for use in Residential and commercial
applications since early 2000's
1991 Florida Law for water conservation for all new irrigation systems. - ANSWER Since
1991, Florida law requires an operating cutoff switch on all automatically controlled
irrigation systems.
In 2004 Florida legislature issued a directive that requires a rain sensor on all new
irrigation systems.
* Rain sensors are available in both wireless and hard-wired versions.
* They employ hygroscopic disks that operate an electric switch.
SMS: Soil Moisture Sensor - ANSWER Designed to estimate soil volumetric water
content based on dielectric constant of the soil.
They monitor site conditions to determine how much irrigation water is applied
outdoors. These controllers receive feedback from the irrigated system, and irrigation
duration and/or frequency is altered accordingly.
*
Smart controllers come in two varieties
1. Climatologically-based controllers
, 2. Soil moisture-based controllers
*State requirement: The controller shall be able to communicate with a rain sensor in
order to turn off irrigation if sufficient rain has fallen. "Smart irrigation controller that is
connected to the internet is a good idea but not required.".
Irrigation system using reclaimed water. - ANSWER All piping, heads, valves, fixtures
etc. of reclaimed water are to be color-coded, by law, in INDUSTRY STANDARD PURPLE
and labeled "Do not drink this water."
* Do not provide hose connections on irrigation systems that utilize non-potable water
supplies
SDPR pipe shall be manufactured to a minimum wall thickness equivalent to SDR-26 and
shall be identified for non-potable service by either marking or industry standard purple
color
Turfgrass.- ANSWER Water Application Amount An efficient watering wets only the
turfgrass root zone, does not saturate the soil nor allows water to run off.
Florida soils are typically sandy and hold 1" of water in the top 12 inches of soil.
Irrigation head best adapted and most efficient to irrigate a sports field or golf course. -
ANSWER Rotary sprinklers (rotors) are designed to irrigate large turf areas and most
effective for large landscapes.
Spaced 45 feet apart and even further with specialized equipment.
Schedule of PVC pipes most commonly used for pressurized main lines in an irrigation
system. - ANSWER Schedule 40 PVC Pipes are most commonly used for irrigation main
lines which are constantly pressurized.
Pressure ratings drop as pipe size increases.
Industry standard rule is that your normal operating pressure should not exceed 1/2 of
the rated pipe pressure.
