JEFFERSON CITY, MO, SEPT. 10, 2010 – A power outage at a Parkville sewage pump station this morning resulted in the release of an estimated 2,500 gallons of wastewater to a local creek, according to the Missouri Department of Natural Resources.

Parkville officials contacted the department this morning to report an electrical failure at a pump station caused wastewater to back up and escape from a manhole near 9001 McAffe in Parkville. The wastewater then ran into White Aloe Creek in Platte County.

 The overflow began at 6:40 a.m. and was stopped by 7:15 a.m. City crews have cleaned the area and removed debris in the discharge location. 

The department has also directed the city to post public notices at the creek and to take water samples from the creek to be analyzed for E. coli.

Clean water regulations require the city to submit a report detailing the release to the department within five days. The department will base future enforcement action on the city’s report.

 The department considers discharges of wastewater from sanitary sewer collection systems to be potential threats to public health and the environment. Such discharges have the potential to contaminate lakes and streams, causing serious water quality problems.

Sanitary sewer overflows can be caused by obstructions in sewer lines, mechanical failure, infiltration of rainwater and snow melt into aging systems, or undersized systems that cannot compensate 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.

To report an environmental emergency, including after-hour sewage overflows, please contact the DNR spill line at 573-634-2436. To report sewage overflows during regular business hours, contact the nearest regional office.
