CANAL LINING - Considers lining a reach of the AII- <br /> <br />American Canal between Pilot Knob and Drop 1 to salvage seepage <br /> <br />water, at a unit cost of $47.50 per acre-foot. <br /> <br />2. DESAL TI NG OCEAN WATER - Considers a desalting plant on <br /> <br />the California coast at Los Angeles to desalt ocean water, at a unit <br /> <br />cost of $617 per acre-foot. <br /> <br />3. DESALTING PLANT IN IMPERIAL VALLEY - Considers a <br /> <br />desalting plant to desalt either New River or Alamo River water, at a <br /> <br />unit cost of from $256 to $443 per acre-foot. <br /> <br />4. DOMESTIC WASTEWATER RECLAMATION - Considers treat- <br /> <br />ment of effluent from urban areas large enough to provide the maxi- <br />mum quantity of replacement water, at a unit cost of $62 per acre-foot. <br /> <br />5. FEDERAL ACQUISITION OF WATER RIGHTS - Considers <br /> <br />Federal purchase of private water rights to the extent of providing <br /> <br />ii <br />
