Jones Island History:

Opened in 1926, this facility was designated a National Historic Civil Engineering Landmark in 1974. World-renowned for pioneering the way in modern wastewater treatment technology, Jones Island was also one of the first facilities in the world to produce fertilizer as the by-product of the water reclamation process: Milorganite®.  Capable of treating more than 300 million gallons a day, the facility is owned and governed by the Milwaukee Metropolitan Sewerage District (MMSD) and operated and maintained by Veolia Water Milwaukee.

Downspout Disconnection

Every downspout on your home can send 12 gallons of water a minute to the sewer system, which increases the risk of basement backups and sewer overflows. Disconnect and help keep excess water out of sanitary sewers.
