body
BACKGROUND INFORMATION:
The City of Lodi owns and operates a number of water and wastewater facilities, which include the Surface Water Treatment Facility (SWTF), the White Slough Water Pollution Control Facility (WSWPCF), 28 groundwater wells, 17 storm water pumping stations, and 10 sewer lift stations. All of these facilities utilize a computer-monitored alarm response, control, and data acquisition system, commonly referred to as a supervisory control and data acquisition (SCADA) system. The central SCADA system for the water system and storm and sewer lift stations is located at the SWTF. WSWPCF operates independently on its own SCADA system. In addition to the current facilities monitored by SCADA, the Public Works Department has current and future projects that will require SCADA integration, such as the new 1.5 million gallon water storage tank to be located at well site No. 28. The current Professional Services Agreement with Telstar expires on June 30, 2026. Additionally, the SCADA communications hardware that allows for the remote operation of infrastructure has reached end of life and Telstar will be doing the programming of the replacement hardware for the water, storm, and sewer collections systems to allow for a seamless transition between systems.
On June 7, 2023, Council authorized the City Manager to execute a Professional Services Agreement with Telstar Instruments for supervisory control and data acquisition, instrumentation, maintenance and integration services ($225,000). The scope of work included instrument calibration, trouble-shooting, and SCADA integration services at new and existing storm water, water, and wastewater facilities. In addition, Telstar supports the City in case of emergencies.
In May of 2025, the WSWPCF had a catastrophic hardware failure with the main computer server requiring Telstar Instruments on-call emergency services. On August 20, 2025, Council authorized Amendment No. 1 to provide for additional funds ($180,000) to cover the emergency costs.
Currently, there are three capital improvement projects at the WSWPCF, and it is critical that we maintain consistency with the current integrator for a seamless transition to full operations. Telstar Instruments is a highly qualified SCADA service provider with experienced staff. This amendment, if approved, will provide sufficient funding for the integration of these three projects, as well as the normal on-call services necessary to maintain our system through June of 2028.
Staff recommends authorizing the Interim City Manager to execute Amendment No. 2 to Professional Services Agreement with Telstar Instruments, of Concord, for supervisory control and data acquisition and instrumentation, maintenance, and integration services, in the amount of $175,000 (for a total agreement not-to-exceed $580,000), and to extend the current agreement for two (2) years through June 30, 2028.
FISCAL IMPACT:
This work is necessary to optimize remote operation and to comply with monitoring and reporting requirements for the water and wastewater utility infrastructure. This work will not impact the General Fund.
