1 DPR: Sustainable Water for California s Future Jennifer West WateReuse California November 9, 2016

2 Promotes responsible stewardship of California's water resources by maximizing the safe, practical and beneficial use of recycled water and by supporting the efforts of the of WateReuse Association.

3 Potable Reuse Around the World

4 Potable Use Projects PERMITTED GROUNDWATER (8) Existing 200,000 AFY 1.6 M People

5 Potable Use Projects PERMITTED GROUNDWATER (8) Existing 200,000 AFY 1.6 M People PLANNED GROUNDWATER (17) Planned 221,000 AFY 1.6 M People

6 Potable Use Projects PERMITTED GROUNDWATER (8) Existing 200,000 AFY 1.6 M People PLANNED GROUNDWATER (17) Planned 221,000 AFY 1.6 M People PLANNED SURFACE WATER AUGMENTATION (6) Planned 100,000 AFY 800,000 People

7 Namibia DPR Experience Windhoek, Namibia Longest-running direct potable reuse facility in the world; in operation since Providing 35% of the overall drinking water supply for the City. Source of pride for community.

8 Singapore NEWater NEWater can meet 30% of Singapore's total water demand currently, and is set to meet up to 55% of its demand by NEWater used for industrial and reservoir augmentation.

9 CA Legislative Mandate SB 918 (Pavley 2010) WRCA sponsored bill: report to the Legislature on feasibility of developing statewide DPR regulations Defined DPR Created Expert Panel to advise DDW SB 322 (Hueso 2013) WRCA sponsored Required Expert Panel to assess additional areas of research for DPR Established DPR Advisory Group

10 Major CA DPR Milestone Reached Release of draft report to the Legislature on feasibility of developing statewide DPR regulations. DDW Report Expert Panel Report Advisory Group Report Significant step in DPR future for CA.

11 Major Takeaways DDW agrees with Expert Panel that it is feasible to begin process of developing DPR regulations. Expert Panel: DPR research important but not critical for immediate DPR reg. development DDW: Regs can start but, Expert Panel identified DPR research and knowledge gaps need to be addressed and/or completed before DPR regulations are adopted.

12 DPR Definition Challenge DPR includes a spectrum of projects. Statute does not provide specific direction on DPR definition. Expert Panel Report: 2 months and less retention time DPR. SWA regulations not released yet.

13 Addressing Types of DPR DDW report: no specific definition of DPR. DDW recognizes three types of DPR: purified water to small surface water reservoirs purified water to treatment plant or surface water reservoir with reservoir providing no benefit. Purified water directly to a public water system s distribution system. DDW: Need common regulatory framework for all DPR types.

14 DRP Implementation Plan 14 point implementation plan, includes: Six research needs identified by Expert Panel DDW Knowledge gaps Example: Expert Panel stated that projects without R/O could be considered and approved. DDW needs specific reliability criteria.

15 WRCA Comments/Concerns Clarify Phased Process for Different Types of DPR Three types of DPR identified in report No Definition of DPR Align Report to SWA regulations Allow case-by-case approval of DPR project until regulations are developed

16 WRCA Comments Continued Include timelines and funding sources for DPR Implementation Plan Further clarify recommendations in the Implementation Plan. Monitoring raw wastewater Involvement of other Cal-EPA agencies Source control Support development operator certification program

17 Expert Panel Research More specificity and timelines needed to move forward quickly. Ex. Identifying low molecular weight compounds in finished effluent. Problem for all drinking water systems. Realistic and achievable research goals are needed for clear path to DPR.

18 Next Steps Report due to Legislature by Dec. 31, 2016 Release of the SWA draft regulations should help clarify DPR definitional issues WRCA to meet with DDW regarding comment.

19 Reuse Funding Options % low interest loans $960 million Committed Prop $625 million, half grant & half loan Largely Committed, loan pay back will make future grants possible Clean Water State Revolving Fund under stress Loan payback 30 not 20 years, great deal $3 billion in applications for water recycling

20 Conclusions

21 Need to ensure public health protection DPR will be a safe, new water supply for CA Multiple solutions must be pursued Non-potable reuse Indirect potable reuse Direct potable reuse Need additional sources of funding Public acceptance is critical
