Changes

Sewers transport waste away from businesses, homes and other sources to septic tanks, other treatment systems, or community sewers. They are constructed out of plastic, clay or iron pipe and laid at a constant grade of 2% that helps to maintain proper speed of the sewage in the pipeline to minimize clogging. Proper design, installation and maintenance are critical for proper operation.
