Active groundwater inflows through joints and pipe penetrations in three sanitary manholes sealed by polyurethane injection — without taking the sewer out of service.

Infiltration through pipe penetrations in a precast manhole stopped with water-activated resin, keeping fines out of the sewer and the structure in service.

Deteriorated access ladders and landings in two deep sanitary manholes replaced by confined space entry, with the drop pipe secured — manholes safe to enter again.
