16. Abstract

This circular provides a comprehensive and practical guide for the design of stormwater pump station
systems associated with transportation facilities. Guidance is provided for the planning and design of
pump stations which collect, convey, and discharge stormwater flowing within and along the right-of-way of
transportationsystems. Methods and procedures are given for determining cumulative inflow, system
storage needs, pump configuration and selection, discharge system size, and sump dimensions. Pump
house features are identified and construction and maintenance considerations are addressed.
Additionally, considerations for retrofitting existing storm water pump stations are presented.
