Pollution prevention resources and recommendations vary between sectors, since different types of facilities and organizations may handle or generate different pollutants. Below are links to pages with pollution prevention information specific to certain sectors:

Pollution Prevention Week 2019

Each year, the district highlights its pollution prevention initiatives during Pollution Prevention Week. This year, the district is asking community members to make a "clean water pledge" -- a promise to take action to protect water. We'll start off this initative during Pollution Prevention Week (Sept. 16-22) by posting example clean water pledges to our social media pages. Some example pledges include:

Visit our Facebook and Twitter pages during the week to see clean water pledges and to share your own! 

To close out the week, we're also hosting bike tours of the treatment plant on Saturday, Sept. 21 starting at 9 and 10 a.m. Bike on over to see the water you protect every time you keep pollutants out of the drain! Tours are free and open to all. Please RSVP to Emily Jones at

When water goes down the drain, it doesn't just go away. It travels through the sewer system to Madison Metropolitan Sewerage District's Nine Springs Wastewater Treatment Plant before being returned to the environment. While many pollutants are removed at the plant, returning safe, fishable and swimmable water to nature, some pollutants are not removed from wastewater. By preventing these pollutants from reaching the plant in the first place, we can help protect clean water while keeping sewer bills low. 

There are three principles guiding the district's pollution prevention work: Conserve, Protect, and Reflect.


  • Conserve water to ensure an adequate supply of clean, fresh water for future generations.
  • Protect water from pollutants that could threaten human health or the environment.
  • Reflect the value of water in your actions.
