ProgramProtectming the Sacramento Ism- R'i ve Welcome to the Sacramento Region Wastewater Treatment Plant 2017 What We Will Learn Today • Who is Sacramento Regional County Sanitation District (Regional San) and what do we do? • How are we regulated? • How are we funded? • What happens during the wastewater treatment process? • How do we protect the environment? ------------- 1 Milestones in Sacramento's Wastewater Treatment • 22 separate Sacramento County, With one of the wastewater collection the City of largest single federal and treatment Sacramento and, the grants in the nation, systems in City of Folsom form the District begins Sacramento region Sacramento Regional construction of the County Sanitation Sacramento Regional • Many discharged into District (Regional Wastewater local waterways, San) Treatment Plant many into the (SRWTP) American River A$460 million regional program is Construction • Clean Water Act developed completed and passed in 1972 operational in 1982 ------------- Our Service 4 AreartfM e � f i-.:i(]`74 k Fokom Today, Regional Sant , �.

Conveyance Treatment Plant � (SRWTP) 169 miles of interceptor pipes 1,050 acres of process area; 2,150 acres of Bufferlands 58 miles of force mains Handles about 130 millio n 11b gallons per day of wastewater 11 pump stations System operates 24/7/365 ------------- Wastewater Treatment is Highly Regulated • Wastewater treatment plants must obtain and comply with a "Discharge Permit" to operate • Permits renewed every five years • Our Discharge Permit is issued by State of California in accordance with State and Federal law • Discharge Permits dictate the quality of water that must be discharged and are enforceable; non-compliance can result in violations and fines 4 Major Upgrades to Treatment Plant • State required higher level of treatment to remove ammonia, nitrates, and further reduce pathogens • Driven by concerns over Delta ecosystem, water quality • Largest upgrade since Plant's inception; named the "EchoWater Project" • Ammonia removal must be operational by 2021 ; filtration/enhanced disinfection by 2023 Now_ What is the EchoWater Project? • Will replace and upgrade many of our existing EchoWater treatment processes Project Bringing Water Back • Result in a "tertiary treatment" process (from existing "secondary" process) • Will add filtration and additional disinfection as final steps 5 EchoWater P Stats • Program cost estimate: ~$1 .7 billion • Number of discrete projects: 2 0 • Peak monthspending: ;� .. ~$27 million • Estimated daily workers at site: ~300 @ peak ------------- The EchoWater Project Replacing the "heart" of the treatment process IL • — �y y' • • • --- tti^ - Ap , IlkE r s - 4. 6 EchoWater Costs and Status • State Revolving Fund financing approved in April 2015 will save more than a half billion dollars in debt costs over traditional bond funding • Construction climate favorable and many bids coming in below engineers' estimates • Project is UNDER BUDGET • Project is ON SCHEDULE MONO Recent & Future Customer Rates • EchoWater Project funded solely by customer rates • In 2010, monthly rate was $20 • Our current monthly rate is $35; will be $36 on July 1 • Costs continually $35 $32 refined over time $Z9 $2 • Monthly rate in =Zo $ZZ 2023 expected to be $39 ".`n11 2012 2 13 2014 2015 2016 7 So. . ..What Do We Do With All That Wastewater? It all comes here! *V t iiis it ZVI;i Elmo 0 MEWN b.-. Running the Wastewater Treatment Plant • Plant operates around the clock, 365 days per year • Over 375 highly qualified staff at the plant, including: — Operators, mechanics, electricians, lab technicians, engineers, personnel, and IT staff • Plant operations staff are certified by the State • Laboratory also State certified iLT W l 8 What Do We Do With All That Wastewater? - • First bar screens remove large objects from the influent such as wood, rocks, and large items that could damage pumps • Next, wastewater (influent) is pumped into plant ■ MONO r What Do We Do With All That Wastewater? • We remove the grit (coarse material) from the influent in aerated grit tanks Next, primary treatment occurs in covered tanks where heavier material sinks, lighter material floats 9 Grit and Primary Animation What Do We Do With All That Wastewater? • Next, primary effluent is mixed with natural organisms or "bugs" and pure oxygen • The "bugs" breakdown the organic matter ► • The mixture is sent to the secondary sedimentation . Y tanks Video from the Florida State University Research Foundation(FSURF)and Qympus A menca, Inc Rawl 10 What Do We Do With All That Wastewater? • During secondary treatment, the "bugsIft " and organic matter settle out and are removed The clean water (secondary effluent) is then disinfected with chlorine to destroy the �-�M remaining micro-organisms What Do We Do With All That Wastewater? tl • Finally, the effluent flows two miles `- T' ft from SRWTP to the Sacramento River, where it is - dechlorinated � �,• � �� before release till _ • The treated water is discharged from a 1 0-foot diameter pipe along the river bottom ------------- 11 What's Left Behind: Solids Processing Anaerobic Digestion: • Anaerobic "bugs" eat the waste in large heated tanks Sludge is pumped to Solids Storage Basins after 15 days • Methane gas is produced and sent to SMUD's Cogeneration Plant P -@6--.Lwwwww"i What's Left Behind: Solids Processing • Solids Storage Basins: Sludge stored there for 3-5 years • Next: Solids are pumped out; portion of them injected into Dedicated Land Disposal sites - • Other portion sent to Biosolids Recycling Facility; processed _ further and turned into pellet fertilizer i z_• 12 Biosolids Management Anaerobic Digestion ►1� 1� (Existing) 20 Dry Ton/Day Zs�io "" BRF Biosolids o- Solids Storage Basins Recycling Facility (SSBs) (Existing) Lined Dedicated Land � —1 Disposal w _ (L-DLDs) 3 Lined DLDs "Beneficial Use" Biosolids Recycling Facility Design-Build-Own-Operate Agreement • Marketing of biosolids product • Private sector experience — modify operations for optimum product quality • Contractual single point of contact — all functions; design, construction, finance, ops. • Reduced District risk — no service fee payment until facility operational and accepted by District • Unproven technologies • Financial protection against project failure -------------- 13 Proposal Evaluation Criteria Category Criteria Weighting Technical Reliability and Viability 20 —Technical reliability —Technical viability Environmental Impacts 15 Price Competitiveness of Service Fee 40 Financial Qualifications,Financial Plan,Legal Standing,and 20 Contract Position —Financial qualifications* —Financing plan —Legal standing* —Contract osition Proposer Team Experience* 5 Total 100 *Evaluated as part of the SOQ evaluation process.
