Pollution Prevention for Municipalities

Beyond the environmental benefits of pollution prevention, municipalities served by the District stand to benefit as customers by preventing pollution from reaching the treatment plant. A major goal of the District's pollution prevention work is to avoid the need to construct facility upgrades to remove pollutants of concern, since upgrades would be expensive and relatively inefficient in reducing pollution overall. The expense of facility upgrades would be passed along to our customers in sewer rates, so pollution prevention is an effort to protect water quality while keeping rates as low as possible.

As a municipality, you can assist the District in its pollution prevention efforts by minimizing pollution in municipal buildings, encouraging businesses in your municipality to enact pollution prevention measures, and educating residents about what they can do to reduce pollution. This page includes some specific steps you can take to minimize pollutants that the District is focusing on reducing at the treatment plant:


  • Follow required steps of municipalities for chloride reduction in MMSD’s Sewer Use Ordinance (Section 4.7.2).
    • Note that there are different reporting dates specified for various actions. If you choose, you can send items (a), (b) and (c) at the same time to MMSD, attn. Kathy Lake, by June 30 of each year.
  • Improve water softeners in municipal building to minimize salt discharges to the sewer system. To incentivize chloride reductions, MMSD is providing grants for projects that permanently reduce chloride contributions to the sewer system.
  • Send municipal salt applicators to a winter maintenance training with an environmental protection component to learn about optimal salt application rates and de-icing practices. The District offers an annual training jointly with the Madison Area Municipal Stormwater Partnership and Madison Water Utility on safe and effective winter maintenance.
  • Enact a winter maintenance policy for your municipality that incorporates best practices for salt and other ice melter application. Recommended application practices and actions for municipal leaders are part of WI Salt Wise outreach.
  • Educate your residents about steps they can take to reduce water softener salt and road salt. For example, you can distribute MMSD's home salt reduction brochure to your residents through mail or in municpal buildings.


  • Minimize or eliminate mercury in municipal buildings, developing and implementing a mercury minimization plan if necessary. Label any remaining mercury-containing materials, such as boiler switches, to help ensure they are properly disposed of when replaced.
  • Educate residents and businesses in your community about proper disposal of mercury-containing household products, such as by directing them to Dane County Clean Sweep and procedures for spill cleanup.


  • Promote the use of MedDrop for disposal of unused household medications by including information about the program in your outreach to residents.
  • If your community does not have a MedDrop box, you can:
    • Establish a collection box in your police department; or
    • Host medication collection events in your community. The Wisconsin Department of Justice funds statewide drug takebacks twice a year and coordinates with local law enforcement agencies to implement these events.
