Situation at WSSC Before EBS Upgrade

The Washington Suburban Sanitary Commission (WSSC) is a political subdivision of the State of Maryland that provides safe drinking water and wastewater treatment for Montgomery and Prince George’s Counties in Maryland.

WSSC was running version R12.1.3 of Oracle EBS Applications (on-premises) with Oracle Database 11 and was facing operational issues with peripheral systems, as well as end of support by Oracle. The client sought an experienced partner who could help upgrade their system applications to EBS R12.2.9 with Database 19c, upgrade Linux to version 7.9, and Oracle Exadata X2 to X7 in order to maintain system operations, compliance, and ensure continued support by Oracle. This technical upgrade of the system would also provide WSSC with:

  • Enhanced functionality and additional features
  • Improved security
  • The latest GUI
  • Greater accessibility with mobile devices

We are live on R12.2.9. I couldn’t have done it without you guys. The AST Team was tremendous. Thanks for all your support and patience. Our senior management is very happy with the accomplishments of this project. We hit all of our targets.”
