We received a call from a local apartment complex that suffered a broken sewage line under their building in the crawlspace. The leak had been going on for several months without anyone's knowledge.
The cleanup was pretty substantial, it required first a pump-out of standing water then several days of drying using our compact dehumidifiers such as the one pictured here.
A normal sized dehumidifier is about 3x the compact size and could not have fit into the crawlspace. Having the right equipment and training to use that equipment is critical to a successful sewage mitigation.
