Wastewater Treatment Plant Audit
Encina Wastewater Authority
Customer Background
The Encina Wastewater Authority (EWA) is a public agency located in Carlsbad, California. EWA provides wastewater treatment services to more than 400,000 residents in northwestern San Diego County. EWA’s facilities and services are essential for protecting the local ocean environment, preserving public health, and providing recycled water resources for the region. Enterprise Automation has provided sole-sourced automation and integration services to EWA since 2017 as part of a five-year professional services agreement.
Project Background
EWA’s SCADA and controls system has grown over time as a result of numerous contractor projects. Its current condition, in many cases, is not specifically known and new projects or upgrades lack documented justification. As one of the first steps towards justifying a multi-year plan for automation projects, EA engineers spent weeks on-site investigating and documenting the current status and condition of the system.
EA Solutions
EA was able to document the condition of the controls network, as well as the condition of all control panels including pictures and drawing reviews. Site programs were collected and stored for easier access, and for review. A final report summarizing the findings was prepared for EWA staff. This report has been instrumental in planning capital improvement projects and requesting funding for them from EWA board members.
