  5. Draft Paper Review • Introduction

  6. Draft Paper Review • Study Area Characteristics • Hydrologic Features – Raymond and Verdugo Basins • Historic extractions and recharge • Water quality of groundwater and surface water • Land Use • Population Projections – Draft UWMP – Retail agencies (Please see handout) • Beneficial Uses and effluent discharges

  7. Draft Paper Review • Water Supply Characteristics and Facilities • Description of all wholesale and retail entities • Sources of water, facilities, costs, prices • Capacities of facilities and flows • Groundwater management, recharge, overdraft • Water use trends, projections (see handout) • Quality of Supplies • Sources of additional water and plans for new facilities

  8. Draft Paper Review • Wastewater Characteristics and Facilities • Description of wastewater entities • Description of facilities, flows, etc. • Water quality of effluent and seasonal fluctuations • Additional facilities needed • Source of industrial or other problems • Existing recycling • Existing rights to use of treated effluent • Wastewater flow variations

  9. Draft Paper Review • Treatment requirements • Potential uses water quality • Health related water qualities (see handouts) • Discharge requirements – no discharge other than beneficial use • RWQCB requirements – General Permit
