>> date meyerson, sfpuc project manager. as john described in the systems there will be both potable water sources tend seawater sources. in fact on the east side we will have to develop more seawater sources so you're going to have a combination of sources providing the 255,000 gallons per minute . >> thank you. >> i'm looking at one slide about water supply sources. it says there's approximately 60,000 gallons per minute of new sea water supply required for the conventional ef ws. i'm assumingthat's part of the 255,000 demand projection . what is the seawater supply required for the west side or the potable efwf. >> that's 90,000 gallons per minute but we need to meet the demands on the potable. that can be met through potable supplies combined with lake merced. that's what option one is stating that we can meet those through those sources and those options two and three are othe ways to meet that 90,000 gallons per minute . so it's the same performance for all three options, just different water sources, different costs,
