TRI-VALLEY WATER AGENCIES I ESI Joint Tri-Valley Potable Reuse Technical Feasibility Study <br /> Existing wastewater facilities include the DSRSD wastewater treatment plant(WWTP)and the <br /> Livermore Water Reclamation Plant(LWRP)as shown in Figure ES.2.Both DSRSD and <br /> Livermore have existing non-potable recycled water irrigation programs.Secondary effluent <br /> that is not used for producing recycled water is discharged to the San Francisco Bay through the <br /> Livermore-Amador Valley Water Management Agency(LAVWMA)and East Bay Dischargers <br /> Authority(EBDA)facilities. <br /> I - J, -r <br /> r <br /> . - = -r- lE6EtIQ <br /> ■ ar w..a <br /> ww.r. <br /> titre# °,, `.-� '"r"'•'^.m <br /> tie 1 'M«n , <br /> 1 <br /> I . 14 <br /> a , <br /> '6%; - <br /> // <br /> - "'w""k...,J .»N <br /> . or 4araamallon P.W.On <br /> `i" Tr�nara ,' Plant Paan Waw <br /> �V 11 Treatment <br /> Plant <br /> ( '4 i-4‘' '''..-''''''' <br /> i'„ikef, ..: ',,, ''', ? — , : . <br /> +Y ?, �•, Oat Yaffewaw <br /> 1 i ?'aliment Plant <br /> e 3.234 GNI, USW <br /> fit. A. E <br /> Figure ES.2 Existing Water and Wastewater Facifitles <br /> Potable Reuse Status and Regulations <br /> Potable reuse has been utilized successfully by California agencies over 30 years as a means to <br /> extend water supplies.Other states have also successfully implemented potable reuse while <br /> being protective of public health.Project-specific permits for potable reuse have been issued in <br /> California for many years,although now regulations are clearly defined for groundwater <br /> recharge by the 2014 Groundwater Replenishment Reuse Projects(GRRPs)requirements <br /> included in Title 22 and the surface water augmentation SWA regulations were adopted <br /> following a released for public comment period in March 2018.The September 2016 draft report <br /> by the State Water Resources Control Board(SWRCB),titled"Investigation on the Feasibility of <br /> Developing Uniform Water Recycling Criteria for Direct Potable Reuse,"found that it is feasible <br /> to develop uniform water recycling criteria that would incorporate a level of public health <br /> protection as good as or better than what is currently provided in California by conventional <br /> drinking water supplies(SWRCB,2016).The state is now moving forward with developing <br /> regulations for other types of potable reuse. <br /> The term"potable reuse"incorporates all types of reuse whereby recycled water is safely <br /> incorporated into potable water supplies.For the purposes of this study,the term"potable <br />
