MILWAUKEE -- Overwhelmed by the amount of rainfall overnight, the Milwaukee Metropolitan Sewerage District (MMSD) initiated overflows early Wednesday in order to prevent basement back-ups.
 
Untreated sewage is currently being released into rivers like the Kinnickinnic River and then making its way to Lake Michigan.
  
A spokesperson with MMSD said intense rain can overwhelm the system.
 
He said their main priority is to prevent raw sewage from ending up in residents' basements. In order to do that, they trigger a relief valve that allows sewage to bypass the treatment process and be released.
 
The overflows will continue until the system can return to normal levels.
