Simple Yet Powerful

Improvements at an Indiana treatment plant and collections system save operating costs and forestall construction of a new plant

A simple change in effluent filters at the wastewater treatment plant is saving the Indiana city of Crown Point money, time and labor while improving effluent quality. The city is also taking steps to reduce stormwater flows and inflow and infiltration into its combined sewer system, helping delay the $30 million cost of a new treatment plant.

“Our original tertiary filters had gone beyond their useful life,” says Chris Previs, plant superintendent. “They were 30 years old, and needed to be replaced.” Switching filter technology is projected to save $70,000 a year on operations and maintenance.
