Low Pressure Pipe (LPP) System Using EZflow® by Infiltrator Handles Large Flows for Long Term Performance

Stockton State Park in Cedar County, Missouri is a popular recreation and boating area that attracts thousands of visitors each year. Extensive guest facilities include campsites, cabins and duplexes, restroom/shower houses, and a 300-slip marina with a 22-seat snack bar, and watercraft pump-out station. A recreational vehicle (RV) dump station is also provided.

The existing wastewater treatment system was more than 15 years old and consisted of a single-cell lagoon and slow rate land application system. There was also an inactive, dried up lagoon on the site. Total design capacity was less than 150 persons, well below existing or future needs. The discovery of karst activity near the existing site caused the Division of State Parks to initiate efforts to construct new wastewater treatment facilities and properly close the existing active and inactive lagoons.
