Waste arrives at the treatment plant by way of an interceptor sewer, and with the help of lift stations. There are approximately 473 miles of combined sanitary and storm sewers. Placed throughout the City with a continuously monitored alarm system, 25 lift stations and 2 storm stations keep the flow moving in order to complete the journey to the treatment plant. The sewers, lift stations, and all equipment involved require regular maintenance.
Industrial Pretreatment Program
General Industries: 5
The 1st defense against pollution involves public education and Industrial Monitoring. This is called pretreatment. The federal government's role in pretreatment began with the passage of the Clean Water Act in 1972. The act required the U.S. EPA to develop national standards to control industrial discharges into sewer systems. The standards are uniform national requirements which restrict the level of certain pollutants in the sewage from industries. All publicly owned treatment works must enforce the federal standards.
