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?

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

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.

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
