Wastewater Treatment


The City of Auburn Water Pollution Control Facility is located on 23.16 acres at 13790 Jodi Road. The treatment plant process consists of head works with bar screens and grit removal followed by two aerated lagoons operated in series with rock filtration.

Equipment is maintained by daily inspections and a preventive maintenance program. The city also maintains six (6) sewer lift stations.

Self Monitoring Program
The facility operates under the National Pollution Discharge Elimination System (NPDES) permit # IL0022403 and has a designed average flow of 0.62 million gallons per day (mgd).

The facility is operated by an Illinois EPA certified Class 4 Wastewater Operator.

The operator conducts periodic self-monitoring of the treatment system through the sampling and testing of influent, lagoons and effluent.

Analytical testing is performed on-site and is done in accordance with Title 40 Code of Federal Regulations, Part 136 (40 CFR 136). Monitoring is done for Flow, Biochemical Oxygen Demand, Suspended Solids and pH.

The information obtained by the self-monitoring program must be reported to the Illinois EPA on a monthly basis in the form of a Discharge Monitoring Report (DMR).
