Sewer Responsibility Seattle. If you live in Seattle, you are responsible for the sewer line from your property to the main Seattle sewer line. Cured in place pipe lining is an approved and widely used method of restoration for sewer lines. It’s a good idea to have your Seattle sewer line televised so you can see the condition of it before any possible sewer problems get worse and your responsibility gets costly! Perma-Liner will be providing live demonstrations on all of our equipment January 11th – 13th in Clearwater, FL. What better time to get away from the cold, Seattle weather? Call us for details!
