Duluth, MN (Northland's NewsCenter) --- Yesterday's heavy rain fall was the first big test of the new Lake Place sanitary overflow tank in Duluth and things couldn't have gone better.
No untreated overflow sewage made its way in Lake Superior all day Thursday.
Yesterday's three inches of rain hit the Northland hard causing flooding on numerous streets, raging creeks and wet basements, but Duluth's overflow tanks did their job keeping the raw sewage out of the lake.
The Lake Place overflow tank became functional back in January.
Duluth now operates five sewage overflow tanks and together they captured more than 7.8 million gallons of untreated sewage that ovoided overlow into Lake Superior, Thursday.
Duluth created the overflow storage tanks in response to an order from the U.S. Environmental Protection Agency to stop untreated sewage reaching Lake Superior by 2016 or face serious penalties including the blocking of all new development in the city.
