AGENDA ITEM: Resolution Approving the Installation of SCADA Panels by Best Electric at City’s Domestic Wastewater Treatment Plant and Five Lift Stations.
MEETING DATE: December 1, 2015
PREPARED BY: Alfonso Manrique, Alternate City Engineer
REVIEWED BY: Eddie Duque, City Manager
Adopt Resolution No. 2015- , awarding the installation of Tesco Supplied SCADA panels at the City’s domestic wastewater treatment plant and five sewer lift stations to Best Electric.
Since March 2015, the City has been working with Tesco Instruments, Inc. (Tesco) to upgrade the existing SCADA Telemetry System and the integration of five lift stations to the System.
The contract with Tesco Instruments was approved on March 3, 2015 at a regular Council meeting at a contract cost of $208,000.
Tesco’s scope of work did not include the installation of the telemetry equipment panels required at each of the five lift stations and at the WWTP.
Tesco has supplied the panels that are stored at the City’s Public Works Yard ready to be installed. Tesco provided a quote for the installation of the panels using a subcontractor in the Sacramento area. The City requested separate quotes for the same scope of work from three (3) other electrical contractors. Best Electric, a Merced based electrical contractor, was the lowest responsive and qualified bidder at $36,244.00.
Staff is recommending that Best Electric be awarded the contract to install the Panels at each of the five lift stations and WWTP.
The City’s Domestic Wastewater Treatment Plant (DWWTP) was constructed in 2004. The current SCADA system has been in service since the plant was constructed. Some of the hardware and software components are obsolete and need to be upgraded to improve the reliability of the remote monitoring system and to preserve the integrity of the data stored in the servers.
The City’s sewer collection system has five sewer lift stations that are not remotely monitored. Problems at these lift stations are usually detected during necessary routine inspections. A SCADA system at these five lift stations would allow remote monitoring of the equipment and liquid levels. The SCADA will minimize the risk of sewer backups and sewer overflows.

The City’s water system SCADA and DWWTP SCADA use Tesco Controls technology. Staff is familiar with the performance and service provided by Tesco Controls. To maintain consistency in the water and sewer utilities, staff recommended that Tesco Controls provide the upgrade and integration of the DWWTP SCADA and the five lift stations.
Tesco Controls provided a proposal to complete this work. Tesco’s proposal was competitive in price and staff recommended that the project be awarded to Tesco Controls. Tesco’s proposal did not include the installation of SCADA Control Panels at each of the lift stations and at the WWTP. Tesco proposed to use their own electrical subcontractor to perform the installation of the control panels. Staff requested quotes from qualified electrical contractors to install the SCADA Control Panels at each of the lift stations and at the WWTP. Three quotes, in addition to the quote provided by Tesco Instruments have been received and are summarized in the following table:
Tesco Controls (by subcontractor)
After a careful review of all bids, it appears that the lowest responsible bidder is Best Electric with $36,244.00.
Costs associated with the installation of the SCADA Control Panels are not included in Tesco’s Scope of Work and are the responsibility of the City.
The SCADA Upgrades totaling $208,000 are being paid by the Sewer Fund. The additional cost to install the SCADA Control Panels was not specifically budgeted for.
Management is considering using the $22,000 line item for equipment purchases towards this project instead under the sewer fund and/or use funding from the Special District areas know as the Benefit Assessment Districts (BADs) to cover expenditure.
