Storm Water Management
Storm water is a product of precipitation – either rainfall or snow melt. Excess precipitation that is not soaked into the ground runs off through private and public property into storm sewers, ditches, ravines and ultimately into lakes and rivers. Storm water that is absorbed into the ground moves laterally in the form of ground water. In developed land areas, impervious surfaces (roofs, patios, driveways and street pavement) do not permit any absorption, so that precipitation runs off into the storm sewer drainage system. Saturated or frozen soil conditions will also result in run-off during heavy rainfall events.
The storm sewer system collects and discharges rain water runoff from streets and allowable home connections to natural drainage areas. Gutters and downspouts, sump pumps, yard drainage systems, and street inlets are all sources of water that enters the storm sewer system.
Storm sewers within the Village drain water to one of two final discharge points: Lake Michigan or the North Branch of the Chicago River. Residents are reminded that waters collected via the storm sewer system are directly discharged back into the environment without any treatment. The direct disposal of waste products (paint, oils, pet waste, etc) into the storm sewer system is strictly prohibited
If you witness the improper disposal of waste into the storm sewer system, report the incident via the Village's Report a Concern Portal
If you experience clearwater basement flooding, report the incident via the Village's Report a Concern Portal
Examples of clearwater flooding include:
- Seepage (through cracks in basement walls or floor)
- Water entering home through window well
- Water entering home under an exterior basement door
- Water entering garage under garage door
