The heavy rains we received this past weekend have overloaded storm drainage systems around the state and sent large quantities of untreated sewage into Michigan’s lakes and streams. The Saginaw News reports:
In Chesaning, 1.15 inches of rain fell between 7:30 a.m. Saturday and 5 a.m. Sunday. Combined with melting snow, that sent an unknown volume update this of untreated sewage and rain and snow water into the Shiawassee River, said Rodney Cantu, operator of the village’s Wastewater Treatment Plant.
The overflow began at 5 a.m. Sunday and ended at 7 p.m. Sunday.
In Saginaw Township, 0.97 inches of rain and melting snow caused the discharge of approximately 44 million gallons of treated water from the Center Retention Basin into the Saginaw River starting at 1:30 p.m. Saturday. The flow was ongoing as of Tuesday morning, said John C. Henning III, superintendent of the Wastewater Treatment Plant.
This has been an enormous problem for decades in Michigan, where many communities have sewer systems that hold storm drainage and waste water together. Whenever a big storm hits, the sewers overflow and untreated raw sewage is discharged into local rivers and streams.
