Emily Jones, Pollution Prevention Specialist, Madison Metropolitan Sewerage District
Next time you’re at Camp Randall Stadium, take a look around and picture twenty 50-pound bags of water softener salt stacked on top of each of the 80,321 seats. That’s about how much salt makes its way down the drain and to Madison Metropolitan Sewerage District’s wastewater treatment plant every year.
But the salt doesn’t stop there. The treatment plant isn’t designed to remove salt, so salt passes through the plant into local streams, where it can threaten freshwater life. Removing salt at the treatment plant would be expensive and energy-intensive, so MMSD is working to protect water more efficiently by reducing the salt that goes down the drain.
