40 MGDThe challenge
Upgrading Arlington County’s water pollution control plant to meet the Environmental Protection Agency’s Chesapeake Bay pollutant reduction requirements posed a complex challenge. The plant’s capacity was being expanded from 30 MGD to 40 MGD, and Alberici was faced with executing construction on a confined site near a residential area while ensuring seamless operations throughout the project.

Challenge met
Alberici’s innovative approach combined engineering excellence and collaborative value engineering to overcome the challenges. The project encompassed multiple critical components, including new clarifiers, aeration basins, and pump stations. Facing budget constraints, Alberici engaged in a productive partnership with the owner and identified over $29 million in cost savings while reducing the program schedule by six months.
The project’s proximity to a residential zone and Reagan National Airport required precision and noise control. Alberici’s pre-assembly offsite mitigated these challenges and minimized on-site disruptions. Seamless logistics and just-in-time material deliveries were ensured through meticulous coordination. Alberici’s expertise, adaptive strategies, and commitment to innovation led to the successful completion of this essential environmental initiative.
