We came across a customer that was having chronic problems with the sewer line for their septic tank clogging and backing up. After diagnosing, we determined that the sewer line was routed in a way that discourages drainage. It was also pitched improperly and full of grease. In order to remedy the problem we dug up the line and rerouted into the septic tank at a different location. Once we were done the sewer line and septic worked considerably better than before.
