Homeowners and residents in the South Florida community of Palm Beach can avoid many local water restrictions if they have so-called “smart” controllers, or advanced technology on their irrigation systems, according to an agreement reached last week between town officials and the South Florida Water Management District.

The only exception is when the water district itself imposes drought restrictions. Then, residents will have to abide by the restrictions.

Smart controllers, which can cut water use by 25 to 60 percent, precisely regulate irrigation according to local weather and soil conditions. Advanced irrigation systems include conservation-oriented sprinkler nozzles.

Palm Beach and local civic improvement associations have been lobbying residents to switch to “advanced irrigation.”
