City of Oneonta

Wastewater Treatment Plant Upgrades

Project Cost:
$8.6 million

Facility Capacity
4.0 MGD

Like many municipalities, the City of Oneonta owns and operates a wastewater treatment plant that was built more than 40 years ago, and contained equipment that reached the end of its useful life.  Because the plant is located in the Chesapeake Bay watershed, and because many different entities depend on City sewer service (2 colleges, a hospital, 2 nursing homes, and dozens of small and medium-sized businesses), upgrades to this critical infrastructure became necessary.

Following a comprehensive review of plant conditions, Delaware worked with City officials and plant operators to determine the highest-priority aspects of the project and worked to engineer a comprehensive solution to aging infrastructure while staying within the City’s budget.   Delaware further assisted the City by applying for and securing, a WIIA grant of more than $2 million.

Delaware provided engineering and design, bid/award, and construction inspection services to the City for the project, which involved improvements to the control building, primary and secondary clarifiers, trickling filter, RBC’s, dewatering facilities, sludge drying beds, and primary digester. 

Construction was completed in  June 2021. With these upgrades, the plant should provide another 30 years of operation and compliance with stringent effluent limits.
