Smart Irrigation Month is an annual observance held in July to raise awareness about the importance of efficient water use in irrigation practices. The goal is to encourage individuals, businesses, and communities to adopt sustainable irrigation technologies and techniques to reduce water waste while maintaining healthy landscapes and gardens.
It’s not unusual for those with sprinkler systems to simply set a timer and let the irrigation system go to work. However, without the proper components in place, this can easily lead to unnecessary water usage. Here are some smart technologies and practices that you can use to aid in water conservation efforts.
weather sensors
Rain sensors recognize weather conditions and can turn off automatic sprinklers when Mother Nature is already doing the job.
soil sensors
These sensors measure the water content in soil at the active root zone. If the moisture level is above the set point, the sensor will bypass the sprinkler cycle.
update sprinkler zones
Ideally, you don’t want sprinkler zones to overlap or be placed in areas with little need for moisture. Water is often wasted due to poor design that has sprinklers spraying onto driveways, sidewalks, or roads. Zones may need to be adjusted over time as landscaping changes, so it’s a good idea to have your system evaluated by a professional.
upgrade sprinkler heads
Updating your sprinkler heads is an affordable way to make your system more sustainable. Newer sprinkler heads are designed to be more efficient than older models.
replace spray heads with drip or micro-irrigation
These systems can be used in non-turf areas to reduce evaporation by delivering water directly to the root of plants.
make efficient use of time
Don’t set your sprinklers for the middle of the day, particularly during peak summer season. More water is wasted when evaporation rates are highest.
landscape with native plants
Native plants are already acclimated to our area’s weather conditions which gives them the advantage of needing less water.
use mulch
Mulch retains moisture better than many other landscaping materials, reducing the need for frequent watering.
cycle-and-soak
Areas with clay soils or steep slopes may experience water run-off before the yard can properly absorb moisture. The EPA recommends a method called cycle-and-soak in these environments, which divides irrigation runtimes into short intervals with breaks in between. It also suggests alternating the runtime between sprinkler zones.
do a regular audit of your system
Breaks, leaks, and obstructions can impact the efficiency of your irrigation. Make sure you’re regularly checking your system and enlist the help of professionals to service your system at least twice a year. Cleanings should be performed in late fall and late spring. Keep this checklist from the EPA handy in order to assess sprinkler issues.
Now is the perfect time to update your irrigation system! Doing so not only helps the environment, but it can also lower your utility bill, add convenience to your property, and help maintain the health of your yard and garden beds.
