Sewer Backup From time to time, the sewer may backup into a structure. To help prevent this, we suggest you have a backflow prevention valve installed on your sewer line if one is not already installed. These devices are designed to help prevent sewage coming back into the house when a blockage or pressure is caused in the sewer line. Many plumbing companies can assist in the installation process of a backflow valve.
The City of Marengo understands the frustration caused by a sewer backup issue. We have a sewer backup policy in place addressing how these issues are handled. The complete policy can be seen here.
Please note, the city's insurance has historically not covered claims submitted regarding sewer backups. Due to this fact, we suggest you first attempt to file a claim through your homeowner's insurance as some policies have backup coverage. As detailed in the policy, the city will not further consider a claim the insurance carrier denies.
