Interesting Feature of a Water Meter and Backflow Preventer Building

HDC was on M-Engineering’s team to design two buildings to house new backflow preventer and water meters where OSU’s water system connects with the City of Columbus’ infrastructure. Construction completion was delayed due to issues in delivering the specified brick, but the contractor was able to achieve substantial completion in December of 2021.  The available infrastructure made traditional floor drains very expensive, so the team was charged with coming up with another solution if the equipment suffered a catastrophic failure and flooded the buiilding. Our solution: flap valves on the rear elevation that only open with sufficient water pressure!

The southeast corner shows the round openings that are the flap valves that release water during a catastrophic failure
