DELAVAN — Cleanup and recovery efforts remain underway across Delavan after severe flooding on Saturday, Aug. 15, left many residents dealing with water damage, overwhelmed drainage systems and extensive property losses.
In the days following the storm, city crews, county officials, contractors and residents have worked together to assess damage and begin the long process of recovery.
To assist homeowners faced with disposing of flood-damaged belongings, the City of Delavan provided free-use dumpsters at designated locations throughout the community. The dumpsters have allowed residents to remove waterlogged furniture, carpeting, drywall and other household items damaged by floodwaters. City officials said the service was intended to ease the burden on families facing significant cleanup challenges while helping neighborhoods recover more quickly.
Tazewell County also launched a damage assessment survey, encouraging residents affected by the flooding to report their losses. The self-assessment tool is designed to help county and state officials better understand the scope of the disaster and determine where recovery resources may be needed most. Officials emphasized that participation in the survey is critical, as the information collected can help support requests for additional assistance and aid programs.
At the state level, Gov. JB Pritzker signed a disaster declaration covering multiple Central Illinois counties impacted by the flooding, including Tazewell County. The declaration enables state agencies to coordinate resources and support local recovery efforts as communities continue to assess damage and address infrastructure concerns.
Among the most significant issues exposed by the flooding were vulnerabilities within portions of Delavan’s sanitary sewer system. During the storm, some residents reported sanitary sewer backups in their homes as the system struggled to handle the volume of water entering the network.
In response, National Power Rodding, a contractor retained by the City of Delavan, has intensified its ongoing inspection program of the community’s sanitary sewer infrastructure. The company is using specialized cameras to inspect and video record the city’s entire sanitary sewer system.
The goal of the project is to identify breaches, defects or other points of infiltration that may allow groundwater or stormwater to enter what is intended to be a closed-loop sanitary sewer network. During major rain events, excessive inflow and infiltration can overwhelm sewer systems, increasing the risk of backups and other service disruptions.
City officials say locating and repairing those problem areas will be an important step toward improving the system’s resilience and reducing similar issues during future flooding events.
While much work remains ahead, community members, local governments and state agencies continue working together to help Delavan recover.
