Waste Water Treatment Plant


The Moberly Wastewater Treatment Facility (WWTF) was constructed in 1997, financed by a Missouri State Revolving Fund loan that was repaid using a .5 cent sales tax passed by the voters of Moberly. 


Facilities include a dual cell SBR, 2 aerobic digesters, two sludge storage basins, and a biosolids land application farm. Ultra-Violet Disinfection of the wastewater was added in 2010 to reduce the discharge of bacteria to the local stream during the recreation season. 

In addition to the WWTF, 15 pump stations move wastewater and combined sewage and stormwater to the WWTF east of Moberly.  The treated effluent from the WWTF is discharged into a tributary to Coon Creek which meanders through several streams that eventually end up in Mark Twain Lake

Plant Operations

Plant personnel also are responsible for lift station monitoring and maintenance. There are currently 15 lift stations in Moberly, and each lift station is checked daily for proper operation. In the last 15 years, the City has upgraded or rebuilt four of the main lift stations, added two more to serve the Airport and the Walmart Distribution Center, and eliminated one in Allendale Manor. 


WWTF personnel are responsible for testing the wastewater and monitoring the processes to assure that the effluent discharged to the stream meets the limits of the City’s NPDES Permit issued by the State of Missouri.
