PROPOSED GUIDING PRINCIPLES FOR
SATELLITE WATER RECYCLING FACILITIES
• Guiding Principle 1: Cost Neutrality
• Guiding Principle 2: Community Consent
• Guiding Principle 3: Wastewater Supply Availability
• Guiding Principle 4: Mitigation of Technical and Operational
Impacts
• Guiding Principle 5: Readiness and Ability to Proceed
z�
A. GUIDING PRINCIPLE 1: COST NEUTRALITY
1. SWRF Projects will be cost neutral to Central San ratepayers.
2. During the planning of a SWRF Project, and consistent with Central San's approach on new
development projects, appropriate Central San staff time spent supporting the project's
development will be paid by the project applicant.
3. During the start-up and operation of a SWRF Project, any additional operational or maintenance
costs borne by Central San will be fully reimbursed by the benefitting Country Club/golf course
owner/homeowners association (HOA).
4. Any regulatory fines or legal penalties resulting from sanitary sewer overflows from Central San's
collection system that are caused by a SWRF Project's wastewater diversion and/or discharge of
waste -activated sludge will be reimbursed by the benefitting Country Club/golf course
owner/HOA.
5. Central San revenues, generated from the sewershed upstream of a SWRF Project's wastewater
diversion location, will not be shared. These revenues include sewer service charges, Ad
Valorem taxes, and capacity fees.
6. Central San provides wastewater treatment, by a contract with the City of Concord, for the cities
of Concord and Clayton. Payment for this service is based on the flow ratio into Central San's
wastewater treatment plant. Therefore, accurate metering and regular reporting of the amount of
wastewater flow diverted from Central San's collection system will be required.
B. GUIDING PRINCIPLE 2: COMMUNITY CONSENT
Community consent for the overall project concept, its location, and
the financial/ structural arrangements for its construction, long-term
operation, and maintenance is essential for the successful
implementation of any SWRF Project. This includes consent by
Central San customers and any jurisdiction having authority over all or
portions of the SWRF Project, including a city, town, and/or Contra
Costa County.
C. GUIDING PRINCIPLE 3: WASTEWATER SUPPLY AVAILABILITY
1 Central San's mission is to protect public health and the environment. Central
San is committed to considering diversion of its available raw wastewater flow
for potential SWRF Projects, with the understanding that Central San's first
priority is the safe and effective operation of its wastewater collection system.
As Central San cannot control the volume of wastewater generated in the
upstream sewershed, Central San cannot guarantee the volume, quality, and
availability of wastewater flow to a proposed SWRF Project.
Potential regulatory changes, outside of Central San's control, could impact the
upstream wastewater supply volume available to a SWRF Project, including
reductions to indoor water use targets, which can lead to lower wastewater
generation rates.
To the extent it is within Central San's control, Central San will protect the
upstream wastewater supply at a proposed SWRF Project's identified diversion
location by not approving any diversions from Central San's upstream
sewershed. Affkq
D. GUIDING PRINCIPLE 4: MITIGATION OF TECHNICAL AND
OPERATIONAL IMPACTS
The proposed SWRF Project will need to be designed and
constructed in a manner that does not damage Central San's
infrastructure as a result of the diversion of wastewater.
Central San must maintain a minimum amount of wastewater flow in
its collection system to prevent solids from settling. If low flows from
a SWRF Project's diversion causes solids settling or odor issues,
Central San will enlist its collection system operations' crews to
clean the impacted portion of the collection system and the
benefitting Country Club/golf course owner/HOA will need to be
reimburse Central San for that additional cost and remedy the
cause.

E. GUIDING 'JRINCIPLE 5: READINESS AND ABILITY TO PROCEED
Interested applicants should be aware that implementing a SWRF
Project will require substantial planning and development and a
significant capital investment in addition to ongoing operation and
maintenance costs. To assure efficient usage of Central San's staff
resources and forward momentum on SWRF Projects, the following
requirements will be employed:
One-year terms will be used in all future preliminary MOUs and
planning agreements, with a provision to extend the term by written
mutual consent of the parties.
Completion of a feasibility study by the project applicant will be
required. Details of the study contents will be determined by
Central San staff.
