Atlantic Wastewater Treatment Plant Improvements

Prior to construction, the City of Atlantic, Iowa, was operating on a 70-year-old wastewater treatment plant that was in critical need of upgrades. In its current condition, the treatment plant was unable to handle the amount of flow being conveyed into it, resulting in untreated waste water bypassing into the East Nishnabotna River.

Hawkins constructed preliminary treatment facilities, a raw waste station, a flow equalization lagoon, sequencing batch reactors, UV disinfection facilities, sludge holding facilities, and sludge reed beds. These improvements have extended the life of the plant by 50 years, and have increased the design capacity from 3 million gallons per day (MGD) to a peak flow of 15 MGD (a 500% increase).

Included in the scope of work was demolition of most of the existing treatment structures and one building, as well as renovation of the existing operations and laboratory buildings. 

This project was recognized in 2015 by the American Council of Engineering Companies (ACEC) Engineering for its outstanding achievements in engineering, which could not have been accomplished without a successful project delivery. The City of Atlantic, IA and FOX Engineering Associates received the 2nd place Honors.

“Hawkins Construction Company has brought ideas to the District for both cost savings as well as scheduling to keep projects both on time and on budget. To help do this they make time early in the project for both collaborative value engineering as well as learning the intricacies of our projects to avoid potential schedule problems. This understanding of the project helps them with the management of subcontractors and makes for a more organized construction process.”
