Kewo Engineering provided as-needed basis professional services for technical support during the design, bid, and construction of electrical, instrumentation, and SCADA projects. The existing SCADA configuration for the Long Beach water system is complex and gathers information from nearly 30,000 different data points via RTU sites and programmable logic controllers (PLCs) at 85 major equipment sites. The purpose of this project was to ensure and improve overall SCADA system reliability, accessibility, maintainability, and security.  

Kewo Engineering’s services for this project included: 

1. Performed detailed design, we will conduct thorough site walks and investigation at all sites to verify existing conditions and walk through a conceptual basis of design and approach. 

1. Worked side-by-side with the engineers from LWBD, AVEVA technical staffs, and technicians from LWBD to provide high-quality review for various submittals including wiring diagrams, ladder logic, SCADA equipment, and other related components.
