CC 2017-01-24_12b SSLOCSD RWFPS Presentation RECYCLED WATER FACILITIES PLANNING STUDY (STUDY) 2/9/2017 Item 12.b 1 Background In 2014, the Council directed staff to pursue the following goals: Meet the City’s future projected water demand of its buildout population by: Meeting the reduction in per capita use as prescribed in the Water Conservation Act of 2009; Proceeding with work necessary to develop a recycled water project that can be used to prevent seawater intrusion in order to provide long-range protection of the City’s groundwater supply; and Ensure water use efficiency and drought protection through regional conjunctive use, storage and management of surface and groundwater supplies. 2 Background – Recycled Water Progress NCMA Technical Group’s Strategic Plan (2014) Regional Recycled Water Strategic Plan (2014) Integrated Regional Water Management Program funded a basin characterization of the Santa Maria Groundwater Basin (2015) City of Pismo Beach Recycled Water Facilities Planning Study (2015) SSLOCSD/City of Arroyo Grande Satellite Water Resource Recovery Facility (2015), which became the Recycled Water Facility Planning Study in 2016 Regional Groundwater Sustainability Project Letter of Intent (2017) 3 Discussion Today we are happy to report a major milestone with the Study. The past eight months, District and City of Arroyo Grande staff has been busy working with WSC to complete the Study. A full copy of the Study is posted on the District’s website. 4 January 24, 2017 Arroyo Grande City Council Presentation South San Luis Obispo County Sanitation District Recycled Water Facilities Planning Study 5 Presentation Overview Water Supply Treatment Requirements Alternative Analysis Funding and Financing 6 Groundwater Water Supply Ongoing drought has impacted groundwater levels Seawater intrusion detected in 2009 7 Storage in Lopez is Low – 33% 8 Treatment Requirements 9 Treatment Process 10 Alternatives Analysis 11 Onsite Option ATP 12 Offsite Option ATP 13 Phase 2 Quantitative Analysis Results 14 Quantitative Analysis Summary Phase 2 Onsite Option Phase 2 Offsite Option 15 Qualitative/Non-Economic Analysis 16 Onsite vs. Offsite Option Findings Onsite Option Offsite Option 17 Groundwater Recharge vs. Hybrid Findings Groundwater Recharge Alternatives Hybrid Alternatives 18 Funding and Financing 19 Next Steps 20 Acknowledgements We would like to acknowledge the contributions of Project Stakeholders, which include Gerhardt Hubner and John Clemons of the South San Luis Obispo County Sanitation District and Teresa McClish of the City of Arroyo Grande, as well as board members and staff from the other participating stakeholder agencies, shown below.
