district serves about 230 thousand people in that county and it s an agency that almost ran out of water in the 1977 drought and despite major investments in imported water supplies and water recycling the fact is they have been operating in a water supply deficit. thankfully for that period we ve almost always had above average rain fall. if that occurred today, those residents despite all their plumbing facilities and other efficiency measures would have to reduce demand an additional 70 percent in order to keep from running out of water. the choices faces, them like many in the west are not easy and certainly not cheap. you re going to find a common thread the area of cheap and easy solutions to water supply is over. consider the fact that,mufd, is sponsoring around 8 hundred dollars an acre foot if any of you are paying more than that for incentive programs i would love to know but that probably is setg the pace. the district is considering a plant on san francisco bay to
