The City of Collinsville, Illinois is a growing bedroom-type community located approximately 10 miles from downtown St. Louis, Missouri. Due to growth in the area the wastewater treatment plant (WWTP) was nearing critical status. Plans were developed to expand and upgrade the plant. As part of the plans an evaluation of the collection system was initiated in order to determine the flows for plant sizing and permitting.

The collection system consists of 3,091 manholes and approximately 121 miles of sanitary sewer lines that range in diameter from 8-inches to 60-inches. Lift stations and force mains are also present in the system.

The current permit for the WWTP allows for an average daily flow (ADF) of 4.41 million gallons per day (mgd) with a maximum daily flow (MDF) of 7.5 mgd. The plant experienced a peak flow of 19.76 mgd during a rain event that occurred prior to field investigations performed on the collection system.
