PROJECT
N
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

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

ANALYSIS OF DRAINAGE NEEDSSTEPS 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
