Recycled Water: Growth Management Challenges and Opportunities 2011 CALAFCO Annual Conference Thursday, September 1, :15 – 4:45 PM Keene Simonds, Napa LAFCO, Moderator Robert Shibatani, Shibatani Group, Presenter Hossein Juybari, East Municipal Water District, Presenter Harry Ehrlich, San Diego LAFCO, Presenter 1

Recycled Water: Growth Management Challenges and Opportunities Exploring Practices and Trends in Recycled Water Uses and its Relationship with LAFCOs’ Role in Facilitating Orderly Urban Growth Central Session Points… Traditional potable supplies (i.e. snow pack/rainfall/groundwater) are being increasingly taxed with respect to accommodating current demands. Scarcity of traditional potable water supplies is helping to make recycled water an increasingly important component in supporting new growth. Southern California agencies have taken a lead role – by necessity – in investing and expanding recycled water uses to support new growth. Key question going forward: Should recycled water become subject to LAFCO oversight? 2

Recycled Water: Growth Management Challenges and Opportunities First, a Macro Perspective According to Robert… California Annual Average Water Balance Managed Water Use Urban, Ag, Environmental Show magnitudes - spatial contexts Supply Sources It's all about System Yield Diminishment Threats Consumptive Regulatory Institutional Natural/Forced Variability – Hydroclimatology Augmentation Strategies Going Forward Recycled Water 3

Recycled Water: Growth Management Challenges and Opportunities Second, a Micro Perspective from Eastern Municipal Water District… I will be discussing EMWD’s recycled water program (background, usage by customers classifications, treatment capacity, percent recycled used vs. wastewater generated in the service area {this is a good score card}, recycled water rate, Mandatory use policy, & loan program), current and future projects. 4

Recycled Water: Growth Management Challenges and Opportunities Third, What Does this Mean for LAFCO? Wastewater Effluent - Historically a Byproduct of Treatment Recycled Water after Treatment is Now a Valued Commodity Value of Water Supply Sources has Increased Exponentially Reuse of Water Rather than Developing New Water Supply Sources Reinvesting in Community Infrastructure Encouraging Community Development as Environmental Benefit Conservation of Resources – Priority or Requirement? Total Water Management – All Water is Usable Recycled Water Supply Meets Goals of Offsetting Development Impacts & Implementing Conservation Meeting Determinations of Cortese-Knox-Hertzberg Act – GC 56668(b) & (k) Developing a Water Supply Reliability Policy 5
