Benefits of a Sprinkler System Rain Sensor

December 12, 2018

For the last several years, Kansas and much of the Midwest was in a drought, and it rained so infrequently that running your sprinklers in the rain wasn’t much of an issue. Then, in May of 2015, the area received record-breaking rainfall, and over watering became a big issue. Wichita was inundated with 11.77 inches of rain during this time, which is the second-highest May rainfall total since 2008, and over 7 inches higher than average.

With the unpredictable and often extreme Kansas weather, installing a rain sensor on your lawn irrigation system is an easy way to make sure your yard isn’t being watered when it rains. This relatively inexpensive device can help you save money and water, keep your lawn healthy, and reduce the amount of pollutants running off into the groundwater.

How does a lawn irrigation rain sensor work?

A rain sensor should be mounted in your yard, away from trees and the house so it can collect rainwater freely. It is connected to the controls of your lawn irrigation system wirelessly or with a direct wire connection. Rain water is collected in a small cup, and when enough water accumulates, the sensor stops your sprinkler system from running. Depending on the type of sensor, the amount of rain can be measured by weight, an electrode, or with an expansion disk.

Benefits of Installing a Rain Sensor

Convenience

The weather in central Kansas is known for being unpredictable, but manually shutting off your sprinklers every time it rains is a hassle. If you’re at work and there’s a downpour, you’re probably not going to be able to rush home and turn off the sprinkler system. And, if you forget to turn them back on after the storm, you may not notice until your lawn begins to brown. When you’re traveling, a rain sensor will be more reliable than your neighbor when it comes to shutting off the sprinklers during a storm.

Prevent over watering

With the frequent, heavy rains experienced in Wichita during May 2015, many lawns suffered the effects of over watering and too much rain: nutrient loss, disease, shallow roots, more weeds, and an increased need for fertilizer.

Save money

Running your lawn irrigation system uses both water and electricity, but rain water is free. Running your sprinkler system only when needed will lower your utility bills. In fact, you could save as much as 45% on your summer water bill! You’ll also save money on fertilizer, because your grass won’t be stripped of nutrients by excessive amounts of water.

Conserve water

Watering your lawn more than necessary, and especially during a rain storm, wastes water. This may not seem like a big issue when it’s actually raining, but it’s important to save water for when it’s needed, like during drought conditions.

Minimize runoff

The soil in your yard can only absorb so much water at a time. Once the ground becomes saturated, any additional water runs off the surface, carrying pollutants such as pesticides, pet waste, and fertilizer into the groundwater system.
