Irrigation and water districts are faced with the challenge of managing a complex network of facilities to make sure water is delivered where it is needed.  Knowledge of how their systems are connected is vital. In order to help our Districts with their facilities Provost & Pritchard’s GIS staff has created sets of large scale detailed facilities maps.  These highly portable map books were customized for clients.  For example, Shafter-Wasco Irrigation District and Southern San Joaquin Municipal Utility District use their map books to see their facilities as they know them, with labels that are familiar to all staff.  The map books created a common tool for staff to locate facilities as well as plan new projects and maintenance.
