Storm Water Pollution Prevention Program

Protecting Our Water Resources

Inver Grove Heights is fortunate to have an abundance of surface water resources. The city is dotted with wetlands and lakes, and the Mississippi River is the city’s eastern border. These resources are essential to the health of the area’s water table and need to be protected from pollution.

Over the years, our city has adopted a number of policies to protect our water resources for current and future residents. Not only do these policies help protect water quality, but they also prevent property damage due to flooding.

As part of our program to protect water resources, the city applied for and received a National Pollutant Discharge Elimination System (NPDES) storm water permit in 2003. 

A Plan to Control Water Pollution

This federal  permit requires that the city, develop and implement a Storm Water Pollution Prevention Plan (SWPPP) to reduce the discharge of pollutants from its storm sewer system as much as possible. The city’s plan must include the following measures:

  • Public education and outreach by the city
  • Public participation and involvement 
  • Illicit discharge detection and elimination
  • Construction site runoff control
  • Post-construction site runoff control
  • Pollution prevention and good housekeeping measures

Goals Measured Annually

The city must identify Best Management Practices (BMPs) and measurable goals associated with each measure. Our Municipal Storm Sewer Systems Annual Report provides a summary of the city’s compliance with the storm water permit and its progress toward goals.

Please direct questions about the Storm Water Pollution Prevention Plan to the City Engineer.

Did you know that right under your feet there are 106 miles of storm pipe and 5,200 storm drains?

This year the city provided a review of our Storm Water Pollution Prevention Plan (SWPPP) on April 28, 2022:

We want to hear from you! 

Residents and IGH property owners are strongly encouraged to provide feedback on the annual SWPPP report. You may email your input to through May 27.

The SWPPP is a document required by the State and Federal government that outlines how the city will work towards reducing pollution in storm water runoff.
