Visitors will need to pre-register for a FREE 90-minute slot to visit the Jones Island Water Reclamation Facility. Jones Island Tours will not be open to walk-up visitors.

Visitors will learn about the history of Jones Island, the water reclamation process, MMSD programs, the making of Milorganite®, and Veolia North America. Kids won't want to miss the "workhorses of wastewater," collecting a set of "bug" cards, and getting up close and personal with the big trucks! Visitors will also receive a free 5 lb. bag of Milorganite® upon their exit while supplies last.
