Sanitary Sewer Inspections
Starting in February 2020, a contractor (Redzone Robotics) hired by the Village of Carol Stream will be inspecting the Village’s sanitary sewer system. Inspections will occur 7 days a week between the hours of 7:00 am and 7:00 pm.
A condition assessment will be produced on over 500,000 feet of sanitary sewer and nearly 2,500 manholes, most of which has not been inspected since their installation. The inspection is projected to take anywhere from 6 to 10 months, weather permitting. Knowing the condition of our entire sanitary sewer system will allow the Village to program maintenance and capital projects in the most cost-effective manner, while lowering the risk of a sudden failure by identifying sewers that would most benefit from timely and proactive repairs or replacement.
Different equipment will be used depending on the size of the sewer, but the RedZone Robotics vehicles, crews, and equipment will generally be comparable to Figure 2. They are gaining access to the sewer system through manholes, which may require them to partially block a street or access private property via Village easements. All public safety authorities will be notified prior to the inspections. Your presence is not necessary during the inspections, but please mention this notice to your neighbors to help us spread the word and minimize the potential for conflicts.
From our experience with Redzone Robotics in 2017, we know that this process does not normally interrupt sewer service or otherwise disrupt your daily routine. Even though we are not inspecting individual service lines, in rare instances, residents may experience increased water levels into floor drains or lower-level toilets. However, these conditions should only be temporary and dissipate within several minutes.
If you have any questions or concerns regarding this project, or experience any problems during this work, please contact the Department of Public Works at (630) 871-6260. To report problems after regular business hours (7:00am - 3:30pm), please call the Police Department non-emergency line (630) 871-6213.
