How MMSD’s Deep Tunnel System Operates During Heavy Rain
If you have standing water in your basement, DO NOT go into the basement! Electricity + Water = Danger.
Wait for the water to drain out of the basement before entering. Or, call a qualified electrician to disconnect the power before you enter a flooded basement.
Call your municipal public works department to report local flooding, and call your homeowners/renters insurance agent.
Please fill out the "Report a Basement" form to help track flooding in our area, which is shared with the 29 municipalities MMSD serves.
