LINCOLN, Neb. (AP) — Lincoln’s wastewater is helping heat and cool a building on the University of Nebraska-Lincoln’s Innovation Campus.

About 70 percent of Lincoln’s wastewater is treated at the Theresa Street facility that’s near the campus.

The campus uses a renewable energy system that captures heat from the wastewater that’s funneled to the plant. It helps power heating and cooling systems for the Nebraska Innovation Commons and Conference Center.

Executive Director Dan Duncan of the Innovation Campus says the Centralized Renewable Energy System will eventually reduce heating and cooling costs for Innovation Campus partners by up to 30 percent. It’s also expected to be a way to attract companies needing office space but looking to reduce their carbon footprint.
