22 HDR Projects Receive National Recognition

ACEC Honors HDR at Annual Ceremony

The American Council of Engineering Companies has recognized 22 HDR projects with national awards. The projects represent a wide range of disciplines and regions across the United States.

Grand Award

HDR’s Virginia Initiative Plant Nutrient Reduction Improvements project for the Hampton Roads Sanitation District won a Grand Award at the ceremony of ACEC’s 53rd Engineering Excellence Awards Gala online, rescheduled from March this year. A panel of nearly 30 judges selected this year’s most outstanding engineering accomplishments from more than 200 entries, in what’s known as the “Academy Awards” of the engineering industry.

Facing a sanitary sewer overflow consent decree and imminent stricter treatment limits, HRSD initiated the $161 million Virginia Initiative Plant Nutrient Reduction Improvements project to lower nutrient discharges, expand hydraulic capacity and replace aging equipment. HDR designed a unique versatile bioreactor that provides treatment flexibility, allowing in-series or in-parallel operation with the existing 3-stage nutrient removal process to achieve required effluent quality of 5 mg/l total nitrogen and 1 mg/l total phosphorus. The peak flow capacity increased from 80 MGD to 100 MGD with the capability to handle more than 120 MGD in the future. Using a phased delivery approach and fast-tracked construction schedule, the team completed the project on budget and on schedule.
