Presentation Notes
Talking points We recognize that an adequate and reliable supply of clean water is crucial to our sustained development. That is the reason, we have a diversified water supply portfolio. Today there are four primary sources of water for Santa Clara County… Imported water from the Sierra Nevada, Local surface and groundwater, Water Conservation, and Non-potable recycled water

Santa Clara Valley Water District constructed & owns a new recycled water purification facility – completed in early 2014
• 8 million gallons per
day of purified water
• Built in partnership –
Santa Clara Valley
Water District & the
City of San Jose
• Serves Silicon Valley
Presenter
Presentation Notes
This new facility is a vital part of the SCVWD’s plan to continue to ensure a clean, reliable water supply for Santa Clara County We built a duality in this facility in that it can produce 8 mgd of ultra purified water or serve 10 mgd of tertiary recycled water Built as a regional facility with a thought towards future expansion

Independent Advisory Panel Assures Quality
Nationally recognized experts review the District’s approach to potable reuse testing efforts at the purification center – assess,
review, and guide District’s potable reuse efforts

Presenter
Presentation Notes
Talking points In April the Independent Advisory Panel evaluating the District’s potable reuse opportunities and potential held its first meeting. The panel is appointed by the National Water Research Institute, will provide assessment on various issues related to potable reuse such as public health and safety, advanced water treatment design issues, permitting and regulatory requirements, and public outreach and advocacy. It will assess, review, comment and guide the district’s potable reuse efforts. The IAP will be instrumental in providing a third party review of the District’s approach to potable reuse and will be important for gaining public support for future potable reuse projects. Successful IPR projects in Southern California have utilized IAP as a component of these planning efforts.
Phase I: evaluate on-going operational data at SVAWPC – MF: filtrate turbidity, cleaning intervals, integrity
Phase III: quarterly testing over 1 year – Confirm Phase II results over long-term

SCVWD Operators
Large internal candidate pool
Career path mobility & cross-over training opportunities available
SVAWPC operators are T operators
Presenter
Presentation Notes
With three very large drinking water treatment plants, District had Drinking water T license - focus SCVWD has 32 drinking water T-license holders plus 3 with T-5 T licenses as district staff at the drinking WTPs. Over 50 years experience with T-license holders. SCVWD operators have growth opportunities at the District, the SCVWD pays fairly, and over (get data from HR) 90% of the operators stay for the long-haul – starting as entry-level, moving up and staying for 15-20 years. Opened the SVAWPC job postings to W & T, internal and external We started at the SVAWPC allowing for both T and WW operators to quality. We ended up with mostly T operators to begin with and quickly evolved to all T licensed operators and supervisor, while allowing for both. That’s our experience. Knowing that the State of California has more T operators than WW operators, we suspect the treand to continue. Going forward, the District may only advertise for T operators because of the ease of cross-training, career ladder etc. Currently all the operators at the SVAWPC are T operators, although initially there was one W operator for a short period of time. Career path mobility available at the district between the SVAWPC and the drinking WTPs – assistants, journey WTPOs, seniors, supervisors One Supervisor, one SWTO (in hire), WTO, Assistant WTO, career ladder – 7 days a week, all year 10 hour days.

Presenter
Presentation Notes
3 minutes – not animated - Read off list of Ops Training Sign-off sheet, SOPs, etc, It was successful to bring in the operators on the job before the plant became operation. Since that time, we have found our internal training program to be good and we have demonstrated that we can train T2 and T3 license holders to become proficient with the plants operations in about 4 months, less than a year. We have found a strong internal training program to be an essential part of our operator development program. We have a strong On-the-Job training program for our conventional WTPs and now we have developed an equally strong membrane plant OJT program.

Drivers for potable reuse
• Non-potable recycled water
(purple pipe) expansion insufficient to meet future needs
• Additional water conservation efforts insufficient to meet future needs – need the “wet stuff”
• Potable reuse identified as most reliable and cost-effective option, per the District’s Water Supply & Infrastructure Master Plan
Presenter
Presentation Notes
ANIMATED – 2 clicks Here are some drivers for my agency in its consideration for potable reuse. The District’s board has a goal of about 40,000 acre-ffet by year 2025 (10% of our county’s swater needs), and purple piepe non-potable expansion will not be sufficient. The low-hanging fruit on purple pipe has been plucked, and to get We, like other agencies in the state are maximizing our water conservation efforts We need local supplies, in-county supplies, drought-prrof supplies, and potable reuse fits this bill.
