Demands within the City of Marysville, OH, water system have increased steadily in the past 5 to 10 years due to continued growth and associated population increases.  Consequently, the City will initiate a $20 million construction effort next year which includes an inflatable dam and reservoir. 

Special Features

The 4.5-foot-high inflatable diversion dam (one of the first of its kind built in Ohio) and 1.4-billion-gallon reservoir will help to ensure that sufficient supply is available to meet future City water system needs.

Project Components

Replacing an existing surface water supply system, the reservoir will convey water by gravity through a 24-inch raw water main to an existing water treatment plant.  It will be built on a 180-acre upland site.

The Upland Reservoir project also includes a 40 MGD raw water pumping station on Mill Creek that will pump flow through a 36-inch raw water main to the reservoir site.  A raw water intake on Mill Creek is provided behind the diversion dam.  The design additionally includes 18,000 LF of raw water line.

Long-Term Vision

The construction effort is a result of Gannett Fleming planning and design for a new raw water supply that will service the City through the year 2022.
