BACKGROUND

The City requires a reliable Supervisory Control and Data Acquisition (SCADA) system to effectively monitor the City’s water supply and distribution system (wells, treatment plants, reservoirs, and pressure stations) 24 hours a day, 7 days a week.  Components of the current SCADA system have reached the end of their useful life due to obsolete hardware.  In addition, upgraded SCADA system components are required to support future water infrastructure expansion.

 

ISSUES/ANALYSIS

The City utilizes a Water Distribution (SCADA) system to control and monitor the City’s Water Distribution System (System).  Currently, the existing SCADA system utilizes Bristol 33XX (Bristol) hardware.  This hardware has not been available for purchase from manufacturers since 2009 and is considered to be obsolete.  Staff is recommending replacing the Bristol hardware to a ControlWave Micro hardware with Ethernet capability, and upgrading equipment including the server, computers, and laptops.  Updating the System’s hardware will facilitate System expansion and improve reliability.

 

Emerson Process Management Power & Water Solutions, Inc. (Emerson) designed and installed the City’s existing SCADA system and has provided continued technical assistance.  The SCADA system upgrade includes modifications to the existing proprietary Emerson equipment.  Replacement of the Emerson proprietary SCADA equipment with a mainstream SCADA software package would require complete removal and replacement of the existing SCADA system software and components, which represents a much larger effort and therefore a higher cost to the City.

 

The Water Facilities Authority (WFA), of which the City is a member agency, performed a similar SCADA upgrade during fiscal year 2016-17.  Prior to conducting the WFA SCADA upgrade, the City, along with the other WFA member agencies, retained a consultant to prepare preliminary cost estimates to either upgrade the WFA’s existing Emerson SCADA equipment, or to remove and replace the existing SCADA system software and components with a different SCADA software package.  Results of the cost comparison showed that it would cost about 8 times more to remove and replace the existing SCADA system software and components with a different SCADA software package.  In addition, the cost to upgrade WFA’s existing SCADA equipment is comparable to the proposed cost to upgrade the City’s SCADA system.
