Caltrans is trying to cut down its water consumption on highways in Santa Barbara, and San Luis Obispo Counties to help cope with the drought.
The transportation agency says it will install a number of what it calls “smart irrigation” controllers at key locations on Highway 101, and Highway 1. Caltrans officials say the controllers can reduce water usage by more than 50%.
The controllers not only turn off the irrigation systems when it rains,
they can monitor plant health, and just provide water when its absolutely necessary.
The agency is also going to start using recycled water for the landscaping at its facilities in San Luis Obispo.
