Waste Water Treatment Plant
The City of Marshfield operates a modern, Environmental Protection Agency (EPA) and Missouri Department of Natural Resources (MoDNR) permitted, Complete Mix Activated Sludge Wastewater Facility located on the north side of I-44 on Brinkley Road, in addition to 12 sewage pumping stations located at various locations surrounding the City and a 60-acre MoDNR approved sludge disposal site located two miles north of the City off North Marshall Road. The Department also maintains over 60 miles of sewage piping and over 1,050 manhole structures.
The wastewater facility was originally constructed in 1976 and extensively expanded in 2000 to provide treatment of up to 1.5 million gallons per day of sewage and up to 3.5 million gallons per day of wet weather inflow to the collection system. In 2004 the facility and lift pumping stations were updated to include fiber optic capabilities to remotely monitor operations and alarms including the ability to control some of the wastewater treating processes and all twelve lift pump stations.
The Department consists of seven employees presently providing Monday through Friday, 8-hour operation of the facility and equipment with 4-hour operation on weekends and holidays and 24 hour a day on call emergency response as needed.
Due to changing regulations the City in 2012 entered into an agreement with the MoDNR to improve the wet weather flow treatment processes while rehabilitating portions of the sewer collection piping that has served the City for over 90 years.
The proposed projects, funded by the "$9 Capital Improvement Project Fees" on the sewer use bills are projected to not only improve the quality of the wet weather discharge to the receiving stream but also to prevent additional inflows to the aged collection piping while extending the life of the sewer piping from 20 to 50 additional years.
The projects are already under way with completion of the replacement of Lift Station Number 5, located at North Elm Street and DD Highway, in January of 2015. This station has been in use since the early 1960s and has surpassed its cost effective life.
The sewer pipe Phase I lining project is expected to be completed in 2016; wet weather treating process improvements is expected to be completed in 2017 and sewer pipe lining projects Phase II and III is expected to be complete by 2020.
Even though our wastewater system and Department is "out of sight, out of mind" when working properly and meeting regulations, it is due in a large part to the historical attention and fore sight of the citizens of our City whom have supported both bond issues and rate increases to provide above average service for our community while maintaining some of the lowest sewer use rates in the surrounding area.
