A sewer manhole can look like a simple metal cover in a street, yard, or easement, but it plays an important role in maintaining the public sanitary sewer system.
Manholes provide access to the sewer main
Sanitary sewer mains are buried underground, so crews need designated access points. Manholes allow trained workers to inspect the system, lower cleaning or televising equipment into the pipe, and reach key locations when maintenance or repairs are needed.
Why they are placed where they are
Manholes are commonly located where sewer lines change direction, elevation, or size, where lines intersect, and at intervals that allow practical access for maintenance. That means some are in streets while others may be in yards or utility easements.
Keep the area accessible
If a manhole is on or near your property, avoid covering it with landscaping, structures, fences, stored materials, or permanent improvements that would prevent crews from reaching it. Reliable access can make a major difference during an inspection or emergency.
Never open one yourself
A sewer manhole is not a homeowner access point. Sewer systems can contain dangerous gases, moving wastewater, deep drops, and other hazards. Only trained personnel with the proper safety equipment should open or enter a manhole.
Manholes help us maintain the system before problems grow
Routine access supports cleaning, camera inspections, condition assessments, and repairs. These activities help identify cracks, roots, blockages, infiltration, and structural problems before they become larger failures.
If you have a question about a manhole, easement, or sewer facility near your property, contact the Ben Davis Conservancy District before making changes around it.
