Tri-Valley Water Roundtable Discussion Notes Page 3 still being evaluated, it appears that 8,700 acre feet is a reliable estimate. In our analysis, we are identifying options that will not dramatically increase the cost of water. • Desalination is a regional project;we would share the costs as well as the eventual supply for desalinated water.The desalinated water would not come from the ocean directly, but from the Bay estuary which will have less expensive operations costs. • One limitation of desalination is that it is not a locally controlled water source (the broader region would invest in this alternative together). • Cost estimates for the analysis likely do not include inflation. • What would happen if the Delta Fix was never completed? How would that affect our reliability projections, given our current plan?Response: We would expect reliability to drop to 46-51% (at or below health and safety levels). Short-term solutions need to be explored, but the study does have a scenario where the Delta Fix is not completed until 2048. • There is grant money available (potentially$7.5 million) for collaborative projects; if we developed a regional project,we could get some attention. We should come together as a group for the Phase 2 effort. • What is the best approach for elected officials to take towards these issues? Response: Even with El Nino, we're not out of the drought; let's move now and collaborate as partners; local control is a key concern. • The state is already giving money away and eager to show they are doing something tangible; we should move jointly to apply for these funds. • Part of our job is to make sure the byproducts of the IPR process are not harmful. Presentation by the West Basin Water District A presentation was delivered by Ron Rildermuth, the Manager of Public Information and Conservation of the West Basin Water District about recent efforts to gain community support for recycled water and indirect potable reuse.Attachment B includes the slides from this presentation. Workshop participants were invited to provide comments and ask clarifying questions about the presentation. Comments and clarifications included: • Is there is a difference in the public perception of injection versus replenishment (augmentation)? Response: The latter is easier. • Would you suggest preparing a survey before sharing information with the community? Response: Initial survey can be done now and another can be done in two years; staff and elected officials can begin communicating with the public about the concept now. • How did you get the environmental community on your side? Response: We actually could have done a lot more in this area. • Would you expect even stronger community support now for these projects (given the drought)? Response:Absolutely. • Could national laboratories be a potential partner and supporter? Response: It really depends. • For its public outreach,West Basin Water District reached out to elected officials, the business community (Chamber of Commerce), community groups, and other formal and informal leaders in the community. • It is important to build trust and reliability within our communities;West Basin was lucky to have high trust even before public outreach began;they had relatively good
