Fine-Tune Your Irrigation System
to Save Water and Money

For a healthy, drought- arid stress-tolerant lawn and landscape, use less water. Adopting
water-savvy habits also is essential to maintaining and extending your community's
water supply, especially during peak use. Water-efficient habits will result in a healthier
lawn and landscape, in addition to conserving water and saving money. With some simple
practices and new technology, existing irrigation systems can be made more efficient—
lowering your water bill, reducing runoff, and saving water.
Reduce demand. Use native plants in
your landscape—they require less care
and water than ornamental varieties—and
apply mulch around shrubs and garden
plants to reduce evaporation.
Less is more. If you step on your lawn
and the grass springs back, it does not need
to be watered. Watering plants too much
and too frequently results in shallow roots,
weed growth, disease, and fungus.
Look for the label WaterSense labeled
irrigation controllers act like a thermostat
for your sprinkler system, telling it when to
turn on and off using local weather data.
WaterSense labeled controllers can help
you save water, time, and
money when compared
to use of a conventional
Seasons change, so
should your system.
Familiarize yourself with the
settings on your irrigation
controller and adjust the
watering schedule regularly,
if you haven't upgraded to a
weather-based controller,
to conform with seasonal
weather conditions.
Play "zone" defense.
Schedule each individual
zone in your irrigation
system to account for the
type of sprinkler, sun or
shade exposure, and the soil
type for the specific area. The same watering
schedule rarely applies to all zones in the
Make it a date. Inspect your irrigation
system monthly. Check for leaks, broken or
clogged sprinkler heads, and other problems,
or engage an irrigation professional
to regularly check your system. Clean
micro-irrigation filters as needed.
Get your head adjusted. Correct
obstructions in sprinkler heads that
prevent sprinklers from distributing
water evenly. Keep water off
pavement and structures.
Check for WaterSense!
A certified irrigation professional can
design, install, maintain, or audit your
system to ensure optimal
efficiency using the proper
amount of water to maintain
a healthy landscape. Ask if
your irrigation contractor has
been certified by a WaterSense
labeled program, a mark of
distinction that means he or
she has been certified by a
program that focuses on water efficiency.
Flip to a switch, Rain shutoff switches,
required by law in many states, turn off your
system in rainy weather and help compensate
for natural rainfall. This inexpensive device
can be retrofitted to almost any system.
Easy does it. Install low-volume micro-
irrigation for gardens, trees, and shrubs.
Micro-irrigation includes drip (also known
as trickle), micro-spray jets, micro-sprinklers,
or bubbler irrigation to irrigate slowly and
minimize evaporation, runoff, and overspray.
Watch the clock. Water when the
sun is low or down, winds are calm, and
temperatures are cool to reduce evaporation.
You can lose as much as 30 percent of water
to evaporation by watering when it's hot and
