Project Design a stormwater drainage system for the city of Bluffdale • Assess current infrastructure • Assess current drainage needs for a 100 year 24 hour storm • Design of new infrastructure using EPA SWMM • Prepare a cost estimate N
Existing Infrastructure Map of Existing Inlets and Pipe Locations Map of Existing Inlets and Pipe Locations
Existing Infrastructure • 3 Drains in Neighborhood • 1 drain has no pipe exit • 2 drains empty into trench • 9 Drains on Northern Street • Pipes over to Bangeter Highway system
Steps Map of Drainage Basins • Create drainage basins for each inlet • Find the depth of the 100 year 24 hour storm • Calculate flow lines and accumulations • Calculate curve number using soil type and land use data • Export information into HEC-HMS Analysis of Drainage Needs
