Our sewer line backed up during heavy blasting as part of the Carl T. Jones construction during the week of 18-21 Feb 2019. We called Roto Rooter who ran a camera down the sewer line and discovered the PVC had been completely severed with a clean break resulting in a 3" separation between the line and the broken pipe. All of this occurred at approximately 5ft depth and away from any trees or tree roots. The plumber said the giant limestone boulder had clearly moved and severed the sewer line the day we contacted them. According to the City's Terpo Seismographic Services contractor, our home is located within 800 ft of the Carl T. Jones blasting area. I have attached an image that shows the Roto Rooter plumber and the boulder in the excavated area where our sewer line was crushed. We have repaired the sewer line, but at a cost of $3,096.74 to Roto Rooter. Please help me identify how to file this claim.
