In Englewood, we had a costumer with a failing sewer line. The problem was the sewer line cross by the driveway, there was a telephone pole on top and major utilities in the way. The existing 4″ cast iron became deteriorated, while the inside diameter was shrinking from rust barnacle buildup.
Dutra had to replace from foundation to the street curb which was 210 feet long. We dug one hole to install the new 4 inch HDPE sewer pipe through the existing sewer line. The second hole is for the hydraulic powered winch that will burst the old pipe out while pulling the new pipe.
Dutra was able to replace the old 4 inch cast iron line with HDPE which is a seamless pipe done by Pipe Fusing, this process makes a joint less pipe which makes the pipe stronger. By replacing the pipe without digging the entire line up, Dutra will not disturb any existing structures (Driveway, patios, garages, etc).
