Title XVI Success Stories Purpose: History of Title XVI in SF Bay Area Implementation: South Bay Water Recycling (SBWR) in Silicon Valley Expansion: Bay Area Recycled Water Program Innovation: Bay Area Recycled Water Coalition Future Directions: Improving Title XVI Delivery

Title XVI “Reclamation Wastewater and Ground Water Studies” of 1992 Reclamation Projects Authorization and Adjustment Act (PL ) …to “investigate and identify” opportunities for water reclamation and reuse in the West, for design and construction of “demonstration and permanent facilities to reclaim and reuse wastewater, and to conduct research, and surface waters” including desalting, for the reclamation of wastewater and naturally impaired ground… The Secretary is authorized to conduct research and to construct, operate, and maintain cooperative demonstration projects for the development and demonstration of appropriate treatment technologies for the reclamation of municipal, industrial, domestic, and agricultural wastewater, and naturally impaired ground and surface waters…

Recycled Water Provides the Most Cost-Effective, Reliable Water Supply Sacramento-San Joaquin supplies continue to be threatened by multiple stressors – Drought – Climate change – Degradation of fragile ecosystems Locally produced, renewable recycled water provides an immediate supply that “bridges the gap” to other long-range solutions

South Bay Water Recycling “Providing drought proof, high-quality water for our community.”

SBWR Regulatory History SF Regional Water Quality Control Board Basin Plan prohibits discharges into south San Francisco Bay: – Less than 10:1 minimum initial dilution, – Discharge to dead-end sloughs, and – Discharge south of the Dumbarton Bridge. SJ/SC WPCP upgrades to 3° treatment, forms South Bay Dischargers Association (SBDA) with Palo Alto, Sunnyvale to demonstrate “net benefit” RWQCB reviews SBDA study, recommends 120 MGD flw limit on San Jose discharge due to fresh water conversion of salt marsh (Order No )

SBWR Regulatory History (cont’d) City of San Jose “South Bay Action Plan” provides for alternative to construction of deep water outfall: – 380 A salt marsh mitigation – 12 MGD water conservation – MGD of water recycling State and Regional Boards accepts SBAP in lieu of 120 MGD flow limit (Order WQ 90-5) and require construction of 15 MGD SBWR Phase 1A and up to 47 MGD of future reuse projects (91-152, ) San Jose Area Reclamation and Reuse Program Authorized in Title XVI of PL

System Capital Cost = $248 million Phase 1A: $140 million ($32.5 million federal) Phase 1B: $82 million ($20.5 million) Phase 1C (ARRA): $15 million ($6.5 million)

San Jose’s proposed indoor use requirements Existing Outdoor Use Rules > 10,000 sf must be plumbed for recycled water (§ ) Must connect to recycled water when available (§ ) Planning Director can exempt facilities from requirements Proposed Indoor Use Rules Install dual-plumbed systems for indoor use within SBWR Service Area (1/2 mile) or >50ksf. Connect when recycled water available. Planning Director can exempt facilities from requirements

USBR-funded research helped SBWR address salinity issues Comparison of Advanced Treatment Methods for Partial Desalting of Tertiary Effluents (USBR, SCVWD, City of San Jose, 2004) compared reverse osmosis, electrodialysis reversal to improve recycled water quality.

Bay Area Recycled Water Coaltion (BARWC) Expands to SF Bay Area

BARWC Brings Communities Together and Promotes Sustainable Water Use

“The challenge for Congress is that stakeholders’ perspectives on how to improve the program are fundamentally different. Project sponsors generally prefer a more streamlined project development process and expanded program appropriations, while the Administration supports a smaller, more focused program with long-term objectives tied to federal interests.”

How Can We Improve? 1.Continue to invest in research and development of new technologies to speed construction, improve water quality 2.Federal funding should continue to bring partners together to promote sustainable water reuse – Encourage local agencies to work across jurisdictional boundaries – Incentivize new customer connections (e.g. tax credits for industrial customers) – Emphasize benefits to gain support for funding authorized projects 3.New competitive programs should augment, not replace existing Title XVI project funding – Minimize duplication of local, state planning and design effort – Create ongoing local-state-federal working group to provide “continuous improvement” of Title XVI program

Conclusion On a life-cycle basis, recycled water projects continue to provide the least expensive, most reliable water supply available in the Western US Federal support is needed to ensure that long- term benefits are not obscured by cheaper short- term alternatives The Title XVI program continues to play a major role in developing the recycled water market and ensuring the success of future local projects
