Sewer system evaluation tools available

摘要

The U.S. sanitary sewer infrastructure is aging. Some sewers are more than 100 years old. Nationwide, there are more than 19,500 municipal sanitary sewer collection systems serving an estimated 150 million people and about 40,000 sanitary sewer overflow (SSO) events per year. Addressing aging water infrastructure challenges is one of the top national water program priorities and a top priority of the U.S. Conference of Mayors (Washington, D.C.).
