Rain Sensors

Keep your lawn green while saving water, money
Does your automatic sprinkler turn on even if it's pouring rain? There is a way to prevent that!

Rain sensors are now required on all newly installed sprinkler systems in Woodbury per Minnesota Statute 103G.298 - Landscape irrigation systems.

A rain sensor detects when it's raining and shuts off the sprinkler system. Sensors can be purchased from some home improvement stores or from your lawn sprinkler service company. The cost for parts is between $40 and $100. There is an additional charge if professional installation is needed.

The savings in water charges from the use of a rain sensor could pay for its cost in the first season. It's estimated that a rain sensor will save at least 1,225 gallons of irrigation water per household on every rainy day. If a household is in the second tier of water rates ($1.88 per thousand gallons per quarter), the savings is $2.30 per watering event when the rain sensor senses adequate moisture.

If you would like more information about rain sensors, contact your sprinkler supplier, home improvement store, or the Woodbury Public Works Department at (651) 714-3720 or click on publicworks@ci.woodbury.mn.us.
