US 17 Spring/Fishburne Drainage Improvements
Solutions
Our team started by conducting hydrologic and hydraulic analysis of the study area. We identified the most efficient means of collecting, conveying, and discharging stormwater runoff. The solution resulted in the construction of a deep conveyance tunnel network, a 360,000 GPM pump station, and an outfall into the Ashley River. This new tunnel drainage system allows for more reliable stormwater service under a range of tidal outfall conditions, including sea level rise and storm surge scenarios.
