JEFFERSON CITY, MO., MARCH 26, 2010 – A clogged sewer line in Sedalia resulted in the release of an estimated 2,625 gallons of untreated sewage into a local stream Thursday afternoon, according to the Missouri Department of Natural Resources.

City officials notified the department shortly before 10 a.m. that a clog caused by rags and other debris resulted in a sewer overflow Thursday from a manhole in the 3200 block of West Broadway, allowing the untreated wastewater to reach a ditch that flows into Brushy Creek.

The sewage overflow began approximately 4:15 p.m. City crews cleared the line and the overflow stopped at approximately 6 p.m. The area leading from the manhole to the creek has been cleaned and treated.

 The department considers discharges of wastewater from sanitary sewer collection systems to be threats to public health and the environment because of their ability to contaminate lakes and streams and cause serious water quality problems.

Sanitary sewer overflows can be caused by obstructions in sewer lines, such as in this case, mechanical failure, infiltration of rainwater and snow melt into aging systems or undersized systems that cannot compensation for sudden increases in wastewater.

Communities across Missouri produce millions of gallons of wastewater that must be properly transported and treated before being released to waterways. However, some communities are facing challenges in accomplishing this.

In order to protect public health and the environment, the department requires communities to take appropriate action to eliminate their sanitary sewer overflow issues. To do this, communities should develop a system to track information about such incidents, including the date, time, location and size of the overflow, weather data, who notified them, when they notified the department and the measures taken to respond. The community can then use this data to aid in developing a plan to inspect the collection system, and plan and finance system upgrades.
