A deep-tunnel pumping system for Columbus, Ohio’s OARS project uses adjustable-speed Flygt pumps to manage extreme head variations and efficiently dewater a 215-foot-deep, high-capacity sewer tunnel after major flow events.

The most effective strategy to safely manage a force main inventory is to implement a risk based approach for any data collection, inspection, condition assessment, and management techniques. Using asset risk to guide the management strategies, an owner/operator can ensure they are implementing the right approach, at the right time, with the lowest financial impact.
