The Downers Grove Sanitary District invites the community to visit the Wastewater Treatment Center for the 29th annual Open House on Saturday, Oct. 6.


The Open House is a free, family-friendly event from 9 a.m. to noon on Saturday, Oct. 6 at the District’s Treatment Center, 5003 Walnut Avenue in Downers Grove (three blocks north of Maple Avenue at the Burlington Northern railroad tracks). This is a unique opportunity for residents to experience firsthand how a local wastewater treatment plant operates.


This year plunge into the world of biosolids, one of the by-products of the wastewater treatment process. Learn how they are made, what the benefits of biosolids are and even take some home with you! It’s FREE!


Visitors can tour the plant with one of the District’s wastewater experts to learn about the different processes used to clean wastewater that comes from homes and businesses. They can also talk with sewer system and lift stations experts, see live microorganisms used to clean wastewater and explore the equipment and trucks used around the treatment plant. Refreshments will also be provided.


A majority of the tour is walking outdoors and visitors should dress accordingly for outdoor weather conditions. Tours are good for scout groups looking for merit badges or students seeking extra credit. Anyone bringing a group should call the office at 630-353-3606 to schedule a tour. Individuals requesting accommodations for special needs are asked to call in advance.
