A Water-Smart Solution for
Large Landscapes
,w ¦
Water Sense® labeled irrigation controllers use weather-based or soil moisture-
based technology to water only when needed. By installing one of these
controllers, your facility can reduce water waste, lower utility bills, and grow a
beautiful, healthy landscape.
OUTDOOR WATER USE
Facilities with large, maintained landscapes—schools,
office buildings, hotels, and parks—devote as much as
30 percent of their water use to keeping plants and turf
healthy. It is estimated that as much as 50 percent of
this water is wasted due to overwatering caused by
inefficiencies in irrigation methods and systems.
WATER-SMART SOLUTIONS
Traditional clock- or timer-based controllers adhere to
preset schedules, which can lead to unnecessary
watering, overwatering that damages vegetation, and
other costly inefficiencies. WaterSense labeled
irrigation controllers are designed to water only when
needed, saving you both time and money.
•	WaterSense labeled weather-based irrigation
controllers use local weather data and onsite
conditions to water only when needed.
•	WaterSense labeled soil moisture-based
irrigation controllers detect the amount of water
in the ground and keep sprinkler systems from
watering when not needed.
Both types can be used as stand-alone controllers or
installed with existing controllers as "add-on" or "plug-
in" devices to upgrade an existing clock-based
controller. With proper installation, programming, and
maintenance, facilities that use WaterSense labeled
controllers can use less water outdoors.

The Granite Park office complex reduced its irrigation water
use by about 40 percent after installing a WaterSense
labeled weather-based controller and other upgrades.
SELECT WATERSENSE AND SAVE
WaterSense labeled irrigation
controllers help businesses and
facilities save both water and
money. They are independently
certified to ensure water efficiency
and performance. Studies show
that WaterSense labeled irrigation
controllers can save 7,600 to 15,000 gallons of water
per year. By applying water only when plants need it,
they can reduce annual water bills and offer
convenience and peace of mind while keeping
landscapes healthy.
WATERSENSE LABELED CONTROLLERS IN ACTION: CURBING WATER WASTE
Project: Granite Park office complex 372,000-square-foot landscape in Dallas, Texas
Project overview: Following an irrigation audit, an irrigation professional certified by a WaterSense labeled
program improved the office park's irrigation system's efficiency by installing a weather-based irrigation controller,
rain sensor, and freeze sensor, as well as performing regular maintenance on the existing irrigation system.
Savings: 12.5 million gallons of water and $47,000 in its first year, for a simple payback of 1.5 years
