In Savannah, Georgia, APS cleaned two 12 inch forcemains; one over two miles long and the other over three miles long. Built between 1985 and 1986, the forcemains were exhibiting overflow and very high pressure. APS had the goal of not only cleaning the forcemains but also restoring their original flow capacity and lowering the pressure. This video explains the project, the tools used, and the pigging process.
