Enterprise Automation (EA) was engaged directly by City of Huntington Beach (COHB) with a multi-year contract to provide control system engineering services for the water and wastewater SCADA department. COHB’s first project priority was bolstering the stability and longevity of their Wonderware System Platform water and wastewater SCADA system.

Due to a large quantity of physical servers, EA proposed a solution to virtualize COHB’s platform, upgrade to the latest Microsoft OS versions, upgrade to the latest Wonderware product versions, and establish a platform replica (test platform) to develop and test changes before deploy to site.

Scope for the project included a new server rack, robust enterprise class servers, storage area network (SAN), a new SCADA network core,  improvements to Wonderware architecture, Domain architecture, network architecture, upgrade of COHB’s Wonderware configurations, optimization of remote site communications, and startup.

The project resulted in a reduction of 13 physical servers to 3 servers with an SAN. The two primary physical servers provide redundancy for SCADA services via primary and standby virtual machines. In addition, EA stratified COHB’s SCADA network, from 1 flat network to 4 isolated networks according to function and criticality.

Before the project was completed, EA guided COHB through a Department of Homeland Security SCADA audit of their legacy system. EA cybersecurity knowledge and feedback from the DHS audit workshop was incorporated into the SCADA infrastructure.
