Manhole Inspections in Cincinnati, OH, and the Surrounding Areas

Manhole inspections in Cincinnati, OH

Manhole inspections are generally performed to give an accurate representation of the sewer’s collection system.  They help to determine structural damage to the chamber, assess inflow and infiltration concerns, discover the size of incoming and outgoing pipes and show evidence of surcharge conditions.

Common causes of manhole problems include corrosion, cracks/fractures, displaced joints, deposits in the channel and infiltration.  Leaks can be caused by poorly-fit covers, shifted frames and damaged adjusting rings.

SWS field technicians thoroughly inspect all components of the manhole including cover condition, ring size, structure material, depth to invert measurements, channel flow and any surcharge conditions.  Using a digital camera to record the inspection, further enhances the reporting documentation.
