Efficient Irrigation via “ Smart” Control

Rick Foster

Sr. Product Manager



Current Water Issues

• The cost of water & power is rising annually

• As the population grows, limited water sources strain to

keep up with demand = DROUGHT

• In many cities, water delivery systems were designed to

service a much smaller number of people than is required

today = INFRASTRUCTURE IS STRAINED

• Irrigation is one the most visible forms of water use

and is usually the first to be regulated in a drought

or water shortage condition




• A recent report on the irrigation industry stated that

automatic irrigation systems are one of the largestcauses of over-watering:

– The controller on the typical irrigation system is adjusted an

average of 1-1/2 times per year and many are never adjusted

– Controllers are typically set to apply the peak irrigation

requirement of the year

– The average automatic irrigation system applies 2 to 3 times

the amount of water required by the landscape




• Current politics of irrigation:

– Water bans & restrictions

– Tiered water rates

– Lawn size and landscape restrictions

– Mandatory irrigation audits

– Mandatory “smart” controllers

– Water-efficient product rebates



Efficient Irrigation via “ SMART” ControlKey Concepts

1. Evapotranspiration – Plant Water Need Based on

Changing Weather Conditions

2. Management Allowed Depletion (MAD) – Proven

Method of Irrigation Scheduling




Evaporation




Transpiration is the process by

which plants return water to the

atmosphere. After absorbing water

from the ground, plants release

water through their leaves.

Transpiration helps plants stay cool,in the same way perspiration keeps

humans and animals cool.

Plant Transpiration



Efficient Irrigation via “ SMART” Control

Key Concepts

• Loss of water from

vegetation though thecombined processes of

soil evaporation and

plant transpiration

Evapotranspiration (ETo)




Key Concepts

• Temperature

• Wind

• Humidity

• Solar Radiation

Weather Factors ThatInfluence The ETo Amount




Key Concepts

Historical ETo by Month




Key Concepts

• Maximum % of Plant Available Water (PAW) taken outof soil before irrigating

– % removed; NOT % remaining

• MAD provides a safety buffer

– Broken mains

– Controller downtime

– Weather variations

• Varies by soil type – MAD Ranges from 35% to 50%

Management Allowed Depletion (MAD%)



“ Smart” irrigation controllers work by monitoring andusing information about site conditions (such as soil

moisture, rain, wind, slope, soil, plant type, and more),

and applying the right amount of water to the

landscape based on those factors.

How ET Manager Works

23



ET Manager Rain Gauge: Features• Measures rainfall on-sight so overwatering

does not occur during the next irrigation

event.

• Rainfall interrupt to shutoff irrigation

during the rain.

• Applies only the correct amount of rainfall

to future irrigation calculations

– During a heavy downpour the rain gauge

accounts for increased runoff

– During a light drizzle the rain gauge

accounts for higher absorption24

Rain Bird ESP-SMTSmart Modular Control System

“ ESP” – Extra Simple Programming

Continues the legacy of the Rain Bird ESP

family that customers have embraced due

to its “ease of use” and high quality

combined with

“ SMT” – Smart Modular

TechnologyUses proven scientific principles

to automatically optimize theirrigation schedule in order to

maintain healthy plant material




ESP-SMT Smart Control System

Comprised of:

1. On-Site ESP-SMT Weather Sensor

2. ESP-SMT Smart

Modular Controller




• On-site weather sensor

• Rain Measurement Capabilities

• Automatic "Cycle and Soak"

• Irrigation Schedule optimizing using "MAD" Approach

• Separate Grow-In and Established Modes

• Default or Custom/Advanced Mode

Key “ Smart” Features




Extra Simple – “Configure Controller” and

“Zone Set-Up” ProgrammingWizards

– Self-prompting Programming – HELP Screens

– English/Spanish Screen Text

• WR2’s mounting bracket easily

mounts on walls or gutters

Competition:

Hunter gutter mount is a separate SKU – an extra

expense and inconvenience

Both Hunter and Irritrol mounting brackets are not as

easy to install



Rain Bird’s WR2 Wireless Rain Sensor

Easier to Use and Superior Control

Six rainfall set points between 1/8”

and 1/2” inch

Rainfall adjustment is important

depending on your soil type

“Quick Shut Off” feature

Competition:

Hunter does not have rainfall set points

Irritrol only has four set points



Three adjustable temperature set points

Why is adjustability important?

Rain Bird’s WR2 Wireless Rain Sensor

Easier to Use and Superior Control

Competition: Hunter has only one set point at 37ºF

Irritrol only has one set point at 41ºF



Rain Bird’s WR2 Wireless Rain SensorEasier to Use

Antennas are contained within the sensor and

controller interface

Homeowners will prefer this neat look compared

with external wire antennas

product

Rain Bird’s WR2 Wireless Rain SensorEasier to Use

Competition:

Hunter’s battery life is shown as “good” or “bad”

Irritrol’s battery strength indication is confusing. A

single LED is responsible for communicating

multiple messages



Signals are updated every 45 seconds

Overcomes most line of sight restrictions for freedomin sensor placement

Communication distance of up to 700 feet line-of-

sight

– Calculate 80% of the known or estimated field capacity

• Use the SMRT-Y Auto-set feature



University of Florida Study:

45%-73% Water Savings

• Controller scheduled to irrigate 2 days per

week

• Less than normal rainfall during test

period

• Expect even greater savings when….

– Higher rain fall during test period

– Irrigation > 2 days/week
