Water Conservation & Rehabilitation Efforts

Two studies completed in 2003 utilizing Prop. 13 Funds1.  Modernization of the Distribution System

a.  Considered converting open ditch system to pressurized, piped system; andb.  Considered improvements to existing distributionfacilities to provide system and on‐farm efficiencies

2. Evaluated supply benefits derived from system improvements, from the reoperation of its reservoir system, and from conjunctively managing groundwater supplies with existing surface supplies
