10 Filling the Supply Gaps Strategic Elements Additional Edwards Supplies (underway) Brackish Groundwater Desalination (underway) Expanded Local Carrizo Aquifer (new element) Regional Water Supply Project (RFCSP underway) Demand Reductions (national leader) Page 10

11 Planned Supplies Brackish Desalination Program Southern Bexar County on SAWS property Three-Phase Program Phase 1: 12,200 ac-ft/yr (2016) Phase 2: 12,200 ac-ft/yr (2021) Phase 3: 6,105 ac-ft/yr (2026) $229 million estimated total program cost $145 million for Phase 1 Currently under design Construction award in Feb 2014 Page 11

12 Planned Supplies Expanded Carrizo a New Project Concept In conjunction with ASR Local Carrizo wells Geology and preliminary feasibility indicate up to 21,000 acre-feet of production Total capital costs $34,000,000 Page 12

18 Successful Water Management Increased supplies by 39% since 2004 Including Aquifer Storage & Recovery (ASR), increased by 79% ASR Storing water even during drought Cornerstone of regional Edwards Aquifer Recovery Implementation Program solution Historic Regional Water Partnership with Schertz-Seguin Local Government Corporation Saving ratepayers over $88 million International Model of Water Conservation Page 18

19 Sanitary Sewer Overflows Compliance with the Clean Water Act In March 2007, SAWS was orally notified by the EPA of alleged failures to comply with the Clean Water Act due to the occurrence of sanitary sewer overflows. Negotiations with the EPA/DOJ are ongoing any settlement, consent decree, or enforcement action will result in the imposition of a civil penalty and in required capital improvements and increased annual maintenance and operating expenses - SAWS Comprehensive Annual Financial Reports (CAFRs) Disclosure ( ) Page 19
