Stormwater Pumping Station and Water Quality Retrofit, Ridley Athletic Complex
Loyola University Maryland, Baltimore, MD

Ridley Athletic Complex Stormwater Pumping StationWBCM provided civil engineering services for the design of a stormwater management solution for the Loyola University, Maryland’s Ridley Athletic Complex. During construction of the elevated athletic fields, which were designed by another firm, unforeseen site drainage problems associated with earth retaining structures became apparent. WBCM was brought onto the project to develop design solutions for these drainage issues while the project continued construction.

WBCM performed the analysis and design for the installation of a new stormwater pump station to convey stormwater from 28 acres of drainage area through a new force main to a stable outfall. The station was designed to handle 3 MGD at 50 feet with the ability to handle peaks of up to 138 MGD for the 100-year storm. WBCM designed all supporting grading, electrical, gas, and structural design as well as permitting and construction services.

The stormwater pump station has dual suction lines and a force main to de-water thRidley Athletic Complex Stormwater Pumping Statione existing stormwater ponding area. A sediment forebay was created in the ponding area to prevent debris from interfering with the suction lines. WBCM designed modifications to the existing gravity-fed storm drain system to receive the force main connection and the pump station’s discharge. WBCM also designed the electric service to the pump station, the pump station controls, and the gas main to serve the emergency auto-start generator for the pump station.

WBCM presented the design and technical specifications to Baltimore City’s Environmental Engineering Division and Planning Department, submitted permit documents, and obtained approvals for the new stormwater management facility and the pumping station.
