South Mesa Water Company serves parts of both the City of Calimesa and the City of Yucaipa.

Our service area straddles the San Bernardino-Riverside county line.

The Company’s service area is generally bounded to the north by Wildwood Canyon road, by Holmes Street and a section line on the east, Avenue L and Myrtlewood Drive on the south, and a westerly irregular boundary which crosses Interstate 10 to the northerly boundary.
