JEFFERSON CITY, MO, JULY 12, 2010 – A power outage resulting from severe weather Sunday resulted in the release of an estimated 2,500 gallons of wastewater from a lift station in Lake Ozark, according to the Missouri Department of Natural Resources.
Lake Ozark city officials notified the Department of Natural Resources this morning that a lift station on Legion Road was knocked out of service by severe weather Sunday afternoon, allowing wastewater to back up and eventually flow into an unnamed tributary of the Osage River.
The overflow began at approximately 4 p.m. and continued until approximately 5:30 p.m. City crews cleaned and treated the ground over which the wastewater flowed before reaching a ditch that eventually reaches the Osage River. The rain that accompanied the storm system mitigated the impact of the spill on the waterway, rendering an on-site investigation impractical.
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 mechanical failure; obstructions in sewer lines; 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.
