Jones Island Water Reclamation Facility Turns 100
A Century of Protecting Public Health and Lake Michigan

Operational since 1925, the Jones Island Water Reclamation Facility (Jones Island) has been the public health and environmental stalwart of the Milwaukee region. Built in an era when waterborne disease sickened and killed many people, Jones Island immediately started to protect our residents and clean up Lake Michigan. Today, 100 years later, Jones Island continues to provide this service to a very high standard, resulting in recognition as a national landmark.

Jones Island’s impeccable record of service went beyond treating wastewater; it defined the term sustainability before many even thought of what it meant to be sustainable. Since 1926, the sludge produced at Jones Island has been converted to an organic-based fertilizer. This cradle-to-cradle approach, named Milorganite®, has continued to be an economic engine and an environmental cornerstone for the Milwaukee region. Milwaukee is known throughout the world by this product and attracts thousands of visitors who want to repeat this story in their regions.
Many may think that Jones Island represents the dirty underbelly of our urban society, but to me, it is an illuminating green star that takes the most polluted water and cleans it to an environmentally friendly level. Jones Island provides cleaner water to Lake Michigan and provides fertilizer to help feed our world. In the last 27 years, I have seen our public come to realize what an amazing place Jones Island is. Jones Island is also more than just the equipment that cleans our water; it is the people who have worked there all these years. Their passion and dedication are on exhibit every day. They make Jones Island work!

We are so lucky to have the Jones Island Water Reclamation Facility right here in downtown Milwaukee! Now on to the next 100 years!

Be Safe. Be Understanding. Be Kind.
Kevin L. Shafer, P.E.
Executive Director - Milwaukee Metropolitan Sewerage District
