Understanding the issue

How Stormwater Affects Our Community

Stormwater is rain or melted snow that does not soak into the ground. As it moves across rooftops, roads, driveways, and lawns, it can collect soil, chemicals, litter, and other pollutants.

Our Management Program

The Village works to minimize stormwater pollution through public education, outreach, and practical household guidance that helps residents protect water quality.

What We’re Doing

Following the U.S. EPA Phase II Rule, the program addresses public education, community participation, construction runoff, illicit discharges, post-construction controls, and municipal operations.

Common Pollutants

Motor oil, pesticides, fertilizer, soil, pet waste, and litter can wash into storm drains. These materials can harm aquatic life and create risks for people and the environment.

Why It Matters

Stormwater reaches local water bodies without treatment. Pollution can cause algae growth, oxygen depletion, habitat loss, and reduced opportunities for swimming, fishing, and recreation.

Know the difference

Storm Sewers and Sanitary Sewers

These systems serve different purposes. Understanding where water goes helps prevent harmful materials from entering local streams and waterways.

Storm Sewer

Collects rain and snowmelt from streets and other surfaces, then carries that water directly to local water bodies—usually without treatment.

Sanitary Sewer

Carries household and business wastewater to a treatment facility or septic system, where it is processed before being released.
