2015 smoke testing location map

2015 Smoke Testing

Project Type:

Smoke testing helps us to find cracks, leaks or faulty connections that allow rainwater into the sanitary sewer system. These rainwater connections can overwhelm the sewer system during larger storm events and can cause Combined Sewer Overflow (CSO) to the Mississippi River. The smoke testing project is a part of the City's CSO Program which includes sanitary sewer repairs and upgrades aimed at eliminating CSO. Although the City has significantly reduced the occurrence of CSO more progress is needed to comply with the Federal Clean Water Act and to avoid fines and or additional surcharges for wastewater treatment.
