Comprehensive Sanitary Sewer System Inspection Continues

The City of Westerville Public Service Department regularly monitors, inspects and maintains 174 miles of sanitary sewer lines and more than 4,000 manholes to ensure the proper functioning of the critical infrastructure. In January 2023, the City embarked on a comprehensive plan to improve the sustainability of its sanitary sewer system and contracted RedZone Robotics to provide a baseline snapshot of the entire public sanitary sewer system.

Inspection results will enable the City to make repairs for any imminent areas of concern and develop a sustainable budgeting and project planning process for future projects.

“What we’ve done in the past has been very good for the community, so we’re trying to do the right thing for the future,” said Westerville Public Service Superintendent Tom Hockman.

Since the inspection began, RedZone has identified one issue that required immediate attention. Contractors also identified potential sewer backups, which Service Department staff repaired, avoiding critical repairs in the future.

“The Redzone team shared that Westerville has been one of the best communities to work in and our system is in good condition overall,” said Westerville Utilities Maintenance Supervisor R Johnson.

RedZone will resume inspections this spring, which will only include inspection of the City’s public infrastructure; not residential laterals. Residents who have a manhole on their property are encouraged to clear any coverings that may inhibit or delay inspections. The inspection process includes three phases, so contractors may access manholes on multiple occasions. Residents will be notified via door hanger if property access is needed.

Inspections are projected to be completed in late summer or early fall 2024. RedZone will share deliverables and additional findings with the City, which will be incorporated into a plan for future monitoring, inspection and maintenance.

“Sustainability is really at the forefront of the project and what we’re creating for the future,” said Hockman.
