The request of staff for the City Council consideration is to review and consider for approval the attached proposal and sole source form submitted by Alford, Woods and Childs, Inc (AWC), in the amount not to exceed $42,530.00 for the upgrade of the City’s Supervisory Control and Data Acquisition (SCADA) system software and licenses for the Reuse Reclamation Facility. The software and licenses are the property of Siemens and may only be purchased through their designated reseller, AWC, Inc.

As Council is aware the city employs the SCADA Win CC throughout its utility system, to include the Water Treatment Plant, the Reuse Reclamation Facility, and lift stations. The application of this program allows for the automation, monitoring, data collection and control of these facilities. The Reuse Reclamation Facility, also known as our WWTP, uses SCADA Win CC as a critical program that ensures our facility maintains compliance in its operations.

The SCADA Win CC has been in use at the Reuse Reclamation Facility since 2009 as an upgrade from the previous Realflex SCADA system. The current software upgrades proposed will upgrade the system from version 7.3 to version 19. These upgrades are necessary to improve our technology and security protocols. The upgrades will also allow for improved programming abilities, monitoring and troubleshooting of both the SCADA itself and the mechanical applications to which it is applied. Finally, these upgrades will achieve better functionality with the newer components, such as the Programmable Logic Controllers (PLCs) and HMI screens. The SCADA Win CC has been a secure and reliable program with a diverse array of applications and exceeds many of the industry standards.
