3 — CCCSD Finances/Owns/Operates
Pros
cons
• CCCSD has experience
• Requires long-term, secure form of
owning/operating WWTPs
debt repayment
• Reduces nearby agency
• Potential impact on CCCSD future
concerns (e.g. odors, SSOs)
borrowing capacity
• Eligible for SRF loan '
• Requires additional CCCSD staff and
• Reduced effluent discharge
resources
• CCCSD responsible for all regulatory
• Eliminates potential zoning
compliance
concerns
• Raw wastewater availability may not
• Private partnership interest exists
meet customer needs
• Reduced effluent discharge
• Potential impacts on collection
system and treatment plant O&M
May not be eligible for tax exempt bonds
4 - Public Private Partnership (P3) -
Third Party Finances/Owns/Operates
Pros
Cons
• Lower risks to CCCSD
• Does not require CCCSD capital funds
• Raw wastewater availability
• Does not impact CCCSD borrowing
may not meet customer
capacity
needs
• Does not require CCCSD O&M staff and
• Potential impacts on
resources
collection system and
• P3 experienced in owning/operating
treatment plant O&M
WWTPs
• Potential zoning concerns
• Private partnership interest exists
• Contract operations
• Reduced effluent discharge
5 — Regional Water Partnership
("Water Wheeling")
Pros
Cons
• Centralized recycled water production
9 More complex
(1 centralized plant vs. -20+ SW RFs)
coordination/agreements
• Optimizes O&M efficiency
between water agencies
• Offset refinery recycled water project
State concurrence on water
costs
• Lower cost recycled water compared to
offset concept
Current recycled water quality
SW RFs (economies of scale)
provided CCCSD may not
• Eligible for SRF loan & better positioning
match water quality required
for grant funding
by customers
• Reduced effluent discharge
Longer implementation
• Raw wastewater availability nearly
schedule
guaranteed

Implementing SWRF Program -
Risks to District
Financial Risks
• Qualification for Tax Exempt Financing
• How to ensure full cost recovery of services?
• How guarantee repayment of debt service?
• What is impact on District Debt Capacity and
Credit Rating?
• Will O&M costs be considered too high over
time?
• How to prioritize SWRF vs. District needs?
• How to ensure replacement costs of SWRF
infrastructure are funded in the future?,
0&M Risks
• Change nature of wastewater treated at
Martinez WWTP (Fluws/Luads/Biulugy)
= Increased maintenEimu of c;ulluutiun system
• Unfamiliar technology
= Ruspunsibility fur cumplaint5 (e.g. udur, traffic)
SWRF Customer Impacts
• Raw wastewater availability may not meet
customer needs
• Interruption of service: Operations or
technical issues
• Water duality may not meet Customer
expectations Tor end use
