Comprehensive Planning for Recycled Water Facilities: December 2010 Workshop Insights

This document presents the findings from the Technical Workshop held on December 6, 2010, by the Foothill Municipal Water District on planning for recycled water facilities. It reviews historical studies, facility capacities, and draft paper insights on water supply characteristics, wastewater management, and hydrologic features. Key recommendations, next steps, and funding opportunities, including a grant that could provide up to $75,000 in matching funds, are outlined. The report aims to guide future planning and decision-making related to recycled water projects in the area.

  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
