FROM: John Moss, Utilities Directo
Prepared By: Gary W. Hend son, Water Division Manager
SUBJECT: REQUEST FOR PROPOSALS FOR UTILITIES SUPERVISORY CONTROL
AND DATA ACQUISITION SYSTEM UPGRADE
CAO RECOMMENDATION
Approve the request for proposals (RFP) for Engineering Services for Utilities Supervisory
Control and Data Acquisition System (SCADA) Upgrade, and authorize contract award by the
CAO, if the selected proposal is within the approved budget of$100,000.
DISCUSSION
The City of San Luis Obispo Utilities Department uses SCADA systems to monitor and/or
control water reservoirs, pump stations, water treatment plant operations, water reclamation
facility operations, sewer lift stations and other related facilities. The systems have been installed
over the years, many by in-house staff, and many of the components are over fifteen years old.
There are several different software systems being used to control the operations and within
several years many of the components will no longer be supported by the suppliers due to their
age.
Consultant services are being sought to provide a detailed evaluation of the existing control
systems and provide recommendations for meeting future operational needs. The systems are
heavily relied upon by operations staff to insure safe and reliable delivery of water and
wastewater services. The systems also alert staff to a number of potential system emergencies or
system failures, even during "off hours". The final product produced by the selected consultant
will be a detailed request for proposals to design and install the new hardware, software and
associated programming to provide a fully functional SCADA system to meet the operational
needs for five separate Utilities Department sections: Whale Rock Reservoir, Water Treatment
Plant, Water Distribution, Wastewater Collections, and Water Reclamation Facility.
CONCURRENCES
The Finance and Information Technology Department has been involved in the development of
the request for proposals and concurs with the recommended approach to accomplishing this
proj ect.

FISCAL IMPACT
This project is identified in the 2007-09 Financial Plan, Appendix B, page 3-499. Funding for
the Utilities SCADA (Telemetry) System Upgrade study in the amount of$100,000 is currently
available within the existing Capital Improvement Plan budget, as follows:
Funding Sources Budget
CIP Project#90490951
Water Fund 50,000
Sewer Fund 40,000
Whale Rock Fund 10,000
Total $1009000
ALTERNATIVES
Do not approve the request for proposals. Continued reliance on an old, outdated and
unsupported SCADA system will likely result in future system failures and impacts to system
operations which could result in impacts to customers, violations of regulatory requirements, and
potential regulatory fines. Therefore, this alternative is not recommended.
