Peru, Indiana, a town of nearly 16,000 on the Wabash River, is known as the circus capital of the world. At one time the winter headquarters of several famous circuses, including Ringling Brothers and Buffalo Bill's Wild West Show, it's host to the International Circus Hall of Fame. It's also one of the few cities in the state with combined sewers.
Peru Utilities needed to upgrade its two wastewater treatment facilities to reduce operations costs and expand capacity to promote economic growth. It also needed to upgrade its old main plant to handle stormwater flows as high as 26 million gallons a day (MGD) and prevent combined sewer overflows the plant had been experiencing.
