Workers fix odor coming from wastewater plant in Washington, Mo

Posted: Updated:
WASHINGTON, Mo. (KMOV.com) -- The city of Washington's wastewater treatment plant went online in 2009. It created a powerful odor that had residents holding their noses when they'd drive by.

The plant had more than the normal smells because it was designed to help solve another problem.

"It's a process by which we attempt to break down the solids further down so we have less solids to handle and dispose of," said Jim Briggs, the city's administrators.

After years of complaints and brainstorming to find a solution, workers used some boards, a fiberglass screen and some bags of peat moss to create an air filter that sits over the vents where the smells came out. 

Even better for residents: it cost about $300. It's much cheaper for residents paying for air scrubbers that some plants use.

Since the peat moss filters went in, the complaints have disappeared and so has the smell. Periodically, the moss has to be replaced and the smell returns for a few minutes.
