Citizens Reservoir Wins ACEC Engineering Excellence Honor Award

We’re excited to share that the Citizens Quarry Reservoir project has been awarded the American Council of Engineering Companies (ACEC) Engineering Excellence Honor Award!

This 88-acre, 250-foot-deep former limestone quarry is now the largest reservoir built in Central Indiana since 1968. With the capacity to store 3.5 billion gallons of water, Citizens Reservoir will be vital to helping the region surmount serious drought conditions that caused mandatory water restrictions in the past.  Citizens Reservoir will also ensure adequate water supply to accommodate population and regional economic growth over the next 20 years at a fraction of the cost of building a conventional reservoir.

Schnabel was the engineer-of-record for the tunnels, shafts, and geotechnical design of surface facilities for this great project. We were instrumental in evaluating design alternatives to help the owner select a cost-effective approach. Our project scope comprised subsurface investigation, hydrogeologic model review of groundwater influence on neighboring properties during reservoir filling and operations, development of geotechnical data and engineering reports, and design of the facility’s tunnels, shafts, and tunnel protection canopies to prevent rockfall blockage.

Congratulations to our fellow team members Citizens Energy Group and Arcadis!

Citizens Reservoir will also ensure adequate water supply to accommodate population and regional economic growth over the next 20 years.
