M3 Engineering was a subconsultant to Lochmueller Group for an MSD project helped MSD reduce flooding and backups in the Black Creek watershed in an area north of Clayton Road and west of Big Bend Road in the City of Clayton, Missouri. Private sources of inflow were disconnected and directed to a new enclosed storm system that discharges to a proposed detention basin to reduce peal flows. Downspouts and area drains that were connected to the sanitary sewer system for residences in the Southmoor Subdivision were disconnected and directed to 2,825 feet of new 12 inch to 30 inch storm sewer. M3 Engineering modeled the existing and proposed systems using XP-SWMM to determine the optimal pipe size. The model also included the proposed detention basin, designed to mitigate peak flows before discharging into the adjacent creek.
