Project Audit
In July 2025, WSSC Water engaged WSP USA, Inc., an outside consulting firm, to conduct an independent evaluation and audit of this pipeline project. The goal of this independent review was to identify the underlying root causes of the challenges encountered and capture lessons learned to strengthen future project delivery.
