ACEC-Kentucky recognized two GRW-designed projects during its 2020 Engineering Excellence Awards program in November.
The awards went to two long-time GRW clients: the City of Murray, KY, and Louisville-Jefferson County Metropolitan Sewer District (Louisville MSD).
City of Murray, KY | Bee Creek Water Resource Recovery Facility Expansion: Murray’s Investment in the Future
-
The Bee Creek WRRF Expansion involved increasing plant capacity from 5.25 million gallons per day (MGD) average daily flow (ADF) to 8.75 MGD ADF. The WRRF Expansion combines “the old with the new” by incorporating existing tankage and buildings into the expanded facility to reduce costs. With an eye to the future, the design also focuses on plant performance, operational flexibility, and anticipated regulatory limits. A vertical loop reactor (VLR) – only the second of its kind in Kentucky – was the chosen technology. Read more here.
Louisville MSD | Louisville MSD’s Clifton Heights CSO Storage Basin, Pump Station & Force Main: Giant Underground Basin Exemplifies Collaboration & Waterway Protection
-
The Clifton Heights CSO basin is a below-grade, cast-in-place concrete tank approaching the size of a football field. It’s filled by gravity and emptied by pumping. The basin holds 7.0 MG of CSO water when the basin is full to a depth of 26 feet and empties at a maximum pumping rate of 9.0 MGD. A single-sided basin wall forming method was used in lieu of a double-sided forming method. This resulted in reduced blasting, excavation, rock removal, and concrete wall reinforcement requirements while saving Louisville MSD approximately $2 million. Read more here.
