MSD engineering: extreme, short-duration storms overwhelmed system; full fixes could cost billions
MSD engineers said intense, short-duration rainfall produced storm pulses beyond the system's design; prior East Side study estimated a $2.4 billion comprehensive fix for a 10-year design standard, while MSD identified 10 fast-track capacity projects to nominate for the capital program.
The full story
Reese Johnson, MSD chief engineer, presented engineering analysis showing the recent storms were characterized by very steep rainfall accumulation curves—large amounts of rain in very short intervals—which exceeds what sewer systems are designed to convey.
