According to the American Waterworks Association (AWWA) industry database, there are approximately 1,483,000 km (876,000 miles) of municipal water piping in the U.S. The sewer system consists of 16,400 publicly owned treatment facilities that release some 155 million m3 (41 billion gal) of waste water per day. The total annual direct cost of corrosion for drinking water and sewer systems is $36 billion, which includes the costs of replacing aging infrastructure, lost water from unaccounted-for leaks, corrosion inhibitors, internal mortar linings, external coatings, and cathodic protection.
