Zanja Madre
historic aqueduct in Los Angeles, California)
The Zanja Madre (Spanish: [ˈsaŋxa ˈmaðɾe], "Mother Trench") is the original aqueduct that brought water to the Pueblo de Los Angeles from the Río Porciúncula (Los Angeles River). The original open, earthen ditch, or zanja was completed by community laborers within a month of founding the pueblo. This water system was used for both domestic uses and irrigation to fields west of town. The main zanja ultimately fed eight branch zanjas. This availability of water was essential to the survival and growth of the community founded here. Brick conduits 3 to 3.5 feet (0.91 to 1.07 m) in diameter were built to improve the system after 1884. Eventually the system did not supply enough water to keep pace with population growth and irrigation demand. The system was abandoned by 1904 though portions were still used for storm water purposes. It was maintained by the Zanjero of Los Angeles.
