On the Radio: Think Before You Flush


Our latest radio segment highlights the efforts of University of Iowa researchers Gene Parkin and Craig Just, who are developing an affordable and sustainable way to treat wastewater. Listen.

Iowans, do you think before you flush?

This is the Iowa Environmental Focus.

When you press down on your toilet lever, you probably don’t take the time to think about where your waste goes. You essentially flush it from memory.

But thinking about waste is important. Today, more than 600 communities in Iowa lack adequate sewer or wastewater treatment systems. Some lack a system entirely.

So in some cases, a flush could end up flowing directly into our rivers and streams.

Updating all of Iowa’s wastewater systems to conventional standards would cost more than $1 billion, according to the American Water Works Association.

But Gene Parkin and Craig Just, engineering professors at the University of Iowa, are researching a more sustainable way to treat wastewater at a lower cost to Iowa communities.

They have created a micro-wetlands test site that treats ammonia and other human wastes using plants and nature’s own processes.

This is important research that could soon help small communities across Iowa.
