REPORT - SOLE SOURCE CONTRACT SPECIFICATION FOR TESCO
PROGRAMMABLE LOGIC CONTROLLERS AND SCHNEIDER ELECTRIC
RADIO TELEMETRY SYSTEM FOR CONTROLLER AND RADIO UPGRADES AT
WATER PUMP STATIONS AND SEWER LIFT STATIONS, CONTRACT NO.
C02052
BACKGROUND: The City of Santa Rosa (City) Water and Wastewater (Local)
Operation Division supervisory control and data acquisition (SCADA) and radio
telemetry system provides means for remote monitoring, collection and storage of
operational data, and control of its water pump stations and sewer lift stations. In
August of 2019, a predesign report by Kennedy Jenks identified both the existing
SCADA and existing radio telemetry system as being vulnerable to obsoletion.
The system is comprised of existing solid-state equipment manufactured in the
1980’s and 1990’s, and integrated hardware and software from different
manufacturers. Non-uniform hardware and software has resulted in an increased
frequency of communications errors between various facilities.
Local Operations has standardized its SCADA system with Tesco Controls, Inc.
(Tesco) programmable logic controller (PLC) equipment and technology to provide
remote management of various processes involved with water and wastewater
operations. To support the system, the Water Department is staffed with factory
trained instrumentation technicians that control, maintain, monitor and respond to
system failure. Local Operations is also proposing to standardize its radio
telemetry system with Schneider Electric equipment and technology in an effort to
match the Water Reuse Division. The existing telemetry system is subject to
obsolete equipment and discontinued manufacturer technical support. Upgraded
radios will minimize operational impacts, provide higher data rates, reduce
interference, and provide more efficient use of the overly dense existing wireless
spectrum. It is for these reasons that Local Operations requires Tesco series PLC
equipment and Schneider Electric radio telemetry equipment for the Controller and
Radio Upgrades at Water Pump Stations and Sewer Lift Stations (Project).
Approving such a proprietary specification will maintain reliability and uniform
compatibility with existing equipment and minimize operational impacts to the
division.
RECOMMENDATION: It is recommended by the Transportation and Public Works
Department and the Water Department that the Board of Public Utilities, by
resolution, approve the sole source contract specifications for Tesco Controls, Inc.
