The Effect on Wisconsin
Although you may not always be thinking about what you or your company puts into the sewer system, any material flushed has a large effect on us and our natural habitat and environment.
What we put into the sewer system can impact:
- Water quality for the organisms in the streams.
- Worker health and safety.
- Biology of the treatment plant.
- Quality of our Metrogro.
- Sewers and pumping stations.
Visit and read MMSD’s Sewer Use Ordinance to discover what can and cannot be placed in our sewer system. With the proper education and practices, we can begin to make strides toward a better Wisconsin.
MMSD Takes Preventative Measures
Our advanced treatment plant removes organic material and pollutants like nitrogen and phosphorus, but toxic pollutants can harm treatment facilities or even pass through to the state’s waterways. To avoid this, MMSD has created a pretreatment program to keep Wisconsin safe.
Our Industrial Pretreatment program aims to keep toxic and non-compatible pollutants out of our sewer system by utilizing our protection, prevention and permit philosophy.
- Protection controls pollutants capable of causing immediate or long-term problems.
- Prevention makes sure that toxic or incompatible materials are not flushed down the drain by households and industrial sources.
- Permits and regulations keep toxic pollutants out of the sewer system.
The Importance of Permits
Wastewater pretreatment might be the most successful environmental program that relies on all three levels of government. National, state and local pretreatment regulations all help keep our wastewater safe.
