Each year, potentially millions of gallons of rainwater enters the City’s sanitary sewer system through private infrastructure defects due to age, cracks, and improper connections. This rainwater is unnecessarily treated at the wastewater treatment plant, increasing utility costs. Rainwater entering the sanitary system can also contribute to sewer backups and basement flooding.

The City of Superior Environmental Services Division (ESD) is conducting a study to determine the amount of rainwater removed from residential homes through basement sump pumps. The study area is associated with planned sewer rehabilitation efforts parallel to Newton Creek. Learn more about the 2018 Newton & Nelson Creek Sewer Improvement project.

Your help is requested in assessing the amount of rainwater that is pumped from basement sumps. Information from this survey will only be used for quantifying sump pump discharge and evaluating rehabilitation projects. There is no cost to participants and no further actions will be required from homeowners who complete the survey or participate in the study.

All survey participants living in the project area (see map of project area below) who complete the survey by July 15th will be registered to win a $100 Visa Card
