A new rain sensor law passed in Minnesota has potential to significantly reduce the amount of water wasted on rainy-day irrigation.
In fact, the Minnesota Nursery & Landscape Association is convinced the new regulation will save the state millions of gallons of water.
The law, which received bipartisan support, requires that all landscape systems installed after July 1 include a rain sensor. The sensor turns off an irrigation system during a significant rainfall and prevents a system from turning on when an adequate amount of rain is received.
For commercial systems, the sensor can pay for itself in as quickly as one rainfall – and in 1-2 years for homeowners.
MNLA is developing a brochure about the sensors.
