It will soon take less water to keep the plants green along Highway 101 through the Central Coast.
Caltrans is in the process of installing hardware that will cut potable water demand in half, if not more, for some stretches of the roadway according to District 5 spokesman Jim Shivers.
Part of the plan calls for hooking up to the City of San Luis Obispo's purple pipe system of recycled waste water to the existing network of pipes Caltrans uses to irrigate.
