The City of Fairfield Wastewater Treatment Plant
The City of Fairfield Wastewater Treatment Plant (WWTP) collects wastewater from homes, commercial buildings, and industrial facilities and transports it through a series of pipes known as the collection system to the WWTP.

Wastewater treatment removes harmful organisms and other contaminates from sewage so it can be discharged safely to a receiving stream.

The Fairfield WWTP is a Grade 3 activated sludge oxidation ditch wastewater treatment process. The plant performs the filtration processes that would occur in nature to help remove organic materials. The cleaned water is then returned to the environment via Crow Creek and the biosolids that are generated are stored and applied to designated farmland.

We are located about 1.5 miles southeast of Fairfield at:
2275 Marigold Blvd.
Fairfield, IA 52556

Go south on Highway 1 and turn east on 227th Street (a gravel road). Go due east ½ mile, passing the Iowa DOT maintenance shop. Afterward, 227th Street will turn into Marigold Boulevard, which travels in a southeast direction. Go ½ mile southeast on Marigold and the plant entrance is at the northeast side of an “S” turn.
