There are approximately 55 miles of sanitary sewer and 1150 manholes that belong to the City. We have a combination jetter vac sewer truck that aids in the cleaning of the sanitary and storm sewers.

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 contaminants 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.

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.
