City of Waukesha’s Clean Water Plant
The Waukesha clean water treatment plant treats an average of 10 to 12 million gallons a day, although it’s capable of handling an average of 18.5 million gallons a day and a peak flow of 23 million gallons a day.
It’s a big and important undertaking. Waukesha has over 260 miles of sanitary sewer pipes that carry wastewater to the plant. The pipes range from 8 to 72 inches in diameter. They’re cleaned at least yearly — more often if necessary.
