AGENDA ITEM: Resolution Awarding a Contract for the Water SCADA System Upgrade Project to Tesco Controls.
MEETING DATE: August 2, 2016
PREPARED BY: Noe Martinez, Interim Public Works Director
REVIEWED BY: Odi Ortiz, Interim City Manager
Adopt Resolution No. 2016-_, awarding a contract for the Water SCADA System Upgrade Project to Tesco Controls.
BACKGROUND AND DISCUSSION:
A supervisory control and data acquisition (SCADA) system is used for remote monitoring of equipment operations and for documenting/recording equipment performance. The SCADA system allows the City to operate the water and sewer systems more efficiently and reliably. SCADA records can be used for optimizing system performance and for creating reports such as the annual consumer confidence report and mandatory water report to the California State Water Resources Control Board Division of Drinking Water.
The City’s current water SCADA system was installed in 2006 and no upgrades have been made since it was originally installed. The hardware and software components 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 software component has been obsolete for over five (5) years as it is no longer supported for maintenance or upgrades. The water SCADA system is necessary to provide a safe and reliable drinking water supply to the Livingston residents. SCADA can quickly detect system malfunctions such as pipe breaks or equipment shutoff and send alarms to Public Works staff for immediate response.
The current water SCADA system monitors eight (8) water wells, one 1-MG tank, four (4) storm lift stations, and four (4) sewer lift stations. The new Well 17 is currently under construction and will be added to the water SCADA system once completed.
Public Works staff in the Water Division is able to remotely monitor these facilities. However, Sewer Division staff is not able to do so and must rely on the Water staff when there are calls for service on any of the four (4) sewer lift stations currently integrated with the water SCADA system.
The City recently completed a separate SCADA project for five (5) sewer lift stations that were not been remotely monitored. This project was completed to automate inspections of the equipment and wetwell levels by the Sewer Division staff and minimize the risk for sewer backups and overflows.
The City’s current water and sewer SCADA systems use Tesco Controls technology. The use of other technologies would significantly increase the cost for operating and maintaining the water and sewer systems. There would be added costs for staff training on the use of different technologies and the City would have to maintain a larger inventory for differing system components.
The upgrade of the existing technology would not involve software development work for the water SCADA system compared to a different technology and therefore minimize the capital cost for system installation. Staff is familiar with the performance and service provided by Tesco Controls. To maintain consistency in the water and sewer utilities, staff recommends that Tesco Controls provide the upgrade of the water SCADA system.
Attached is the Tesco Controls proposal (#16E220Q01) to complete the water SCADA system upgrades. Also, attached is a separate Tesco proposal (#16G028Q03) to remove the four (4) sewer lift stations from the current water SCADA system and integrate into the sewer SCADA system for remote monitoring by Sewer Division staff. The SCADA work for the sewer lift stations could be done as a separate and future project if necessary.
Staff recommends that the water SCADA system upgrade work be awarded to Tesco Controls. Staff also recommends that the SCADA work for the sewer lift stations be awarded to Tesco and completed as part of this project unless the City Council elects to postpone this work.
The cost for the water SCADA system upgrade has been identified and will be included in the new FY 2016-2017 budget. The cost for the sewer lift stations integration work has not been allocated yet but can be added to the new FY 2016-2017 budget, if approved by the City Council.
The water SCADA system upgrade will be funded 100% from the water enterprise funds. The sewer lift stations integration work could be funded 100% from the sewer enterprise funds.
(Note from TheGardeningSnail. To find the cost of the projects, you need to look at the Resolution. According to the Resolution, you will find the following:
WHEREAS, the City Council desires to reduce project costs and maintain consistency on the SCADA system by procuring the system upgrade from Tesco Controls, Inc. for the quoted price of $55,475.24 (Base Price plus Optional Adder # 1); and
WHEREAS, the City Council desires to proceed with the integration work for the sewer lift stations at this time by procuring the programming services from Tesco Controls, Inc. for the quoted price of $33,336.64.)
