Toledo, Ohio

Jones & Henry teamed with Black & Veatch Corporation for the design and construction engineering of a new combined sewage overflow control and storage facility. The project site is on City-owned property at International Park, located the east side of the Maumee River. When overflow levels are beyond capacity for treatment at the Bay View Water Reclamation Plant, this facility will hold the sewage and allow measured release to the treatment facility.

Jones & Henry designed the storage facility to capture and store 6.90 million gallons of combined sewage to prevent overflow into the Maumee River. The primary storage structure consists of a 5.20 million gallon, below-grade, reinforced concrete structure on the International Park Site. The storage basin was fitted with a flushing system, a dewatering pump station, and appurtenant systems. The flushing system used flushing gates to remove debris accumulated inside the storage basin. Captured combined sewage is stored in the basin and is conveyed to the East Side Interceptor via the dewatering pump station and ultimately to the Bay View Wastewater Reclamation Plant for treatment.

New diversion/screening structures were constructed on the existing Main Street and Nevada Street sewers for the purpose of diverting potential overflows from the existing outfalls to the new storage facility. Screening equipment was included in the diversion structures to prevent excessive solids from being carried into the storage basin. Flows were directed to the storage basin via an 84-inch conveyance sewer (Main Street Regulator) and a 108-inch conveyance sewer (Nevada Street Regulator). These two conveyance sewers provided the remaining 1.70 mg storage capacity for the facility.

A replacement of the undersized Nevada Street Regulator outfall pipe with a new 72-inch by 108-inch concrete box outfall pipe with a design capacity of 131 mgd was constructed from the diversion structure to the Maumee River.

The Toledo Waterways Initiative began in 2002 and included more than 45 separate projects over the course of 18 years, at a total estimated cost of $527 million. The total Initiative was scheduled for completion in 2020.

Jones & Henry was proud to be part of this integral project to protect our region’s resources.
