Rain sensors are now required on all newly installed sprinkler systems in Prior Lake 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 you would like more information about rain sensors, contact your sprinkler supplier, home improvement store, or the Prior Lake Public Works Department at (952) 447-9896.
