Collection Systems & Conveyance
The system of underground pipes and maintenance structures that convey wastewater has brought dramatic improvements to public health. Most sewers carry wastes from households and commercial establishments and are referred to as sanitary sewers. U.S. EPA estimates the U.S. has about 805,000 km (500,000 miles) of publicly-owned sanitary sewers with a similar expanse of privately-owned sewer systems.
