The Milwaukee Metropolitan Sewerage District (MMSD) reported the following information to the Wisconsin Department of Natural Resources regarding sewer overflows that resulted from the record-setting rain event from heavy rain and snowmelt on February 27, 2023, to March 1st, 2023.
To reduce the risk of wastewater backing up into homes and businesses, a combined sewer overflow started at 11:30 am on February 27, 2023, and ended on March 1st, 2023, at 8:00 am.
MMSD Rain gauges showed at least six areas in the service area that received more than two inches of rain on top of melting snow on February 27, 2023.
One inch of rain in MMSD's service area equals 7.1 billion gallons of water.

As a region, we've invested over $4 billion to reduce sewer overflows. MMSD's current financial forecast through 2032 calls for investing $3.4 billion in clean water infrastructure, flood management, green infrastructure, and debt financing to help protect public health and Lake Michigan.
