WALKER (KWWL) -

Waste water in Walker is now substantially cleaner.

The town recently finished construction of a new treatment facility, which features some unique equipment.

"It's a new system, a continuous flow system," said Kevin Shoop, a Walker Public Works technician. "It's the first one operating in the state of Iowa."

Though it looks like little more than a few ponds and dirt patches, there is more to it than meets the eye. The dirt is actually insulation for 6-foot-deep pits which contain Submerged Attached Growth Reactors (SAGRs), the first for Iowa.

This addition came on the heels of pressure from the Department of Natural Resources.

"The (previous) system did not have adequate capacity and did not meet design standards from the DNR, so the DNR was ready to take enforcement action against the city," said project manager Matt Wildman.

When water enters the facility, it is bright yellow, and is essentially raw sewage. Once it flows through three holding ponds, it's much cleaner, and is filtered clear. After that, it flows through a UV filter, and then out into the nearby creek. This same creek flows right through town.

But now, it's so clean that it could almost be drinking water.

"It's actually probably cleaner water than what is in the creek," Shoop said.
