Key Challenges & Solutions  

This multi-phase project involves complex coordination across multiple engineering disciplines, consultants, and contractors within an active wastewater treatment facility. The design includes a new combined sewer overflow (CSO) bypass system, influent conveyance modifications, upgrades to existing chlorine contact tanks, and a new chemical storage and feed building.

Honor served as the lead civil engineer to the prime A/E, responsible for site planning, layout, and ensuring constructability of design elements. Honor also supported technical review of design documents and development of front-end and technical specifications for bidding and construction phases.
