DeKalb County DWM | Standby Engineering Lift Station Upgrades and Collection System Improvements

Established in 1942, DeKalb County Department of Watershed Management (DWM) services more than 5,000 miles of water and wastewater pipes in the county system. Over the years, Gresham Smith has provided standby engineering services on multiple projects for DWM, including the design and upgrade of numerous lift stations. Our work not only replaced aging infrastructure but also enhanced each station’s performance by making them more energy- and operationally efficient, helping prevent the occurrence of flooding and sewage backups.
