Sewer service involves the collection and treatment of wastewater. Wastewater is "used" water that is deposited into drains by residents and businesses. Flushing the toilet, taking a shower, and running the washing machine are all examples of everyday activities that produce wastewater. This wastewater drains down the sink or toilet and travels through a network of underground pipes known as the sanitary sewer system. Reclaiming wastewater is fundamental to protecting our water supply and guarding against water pollution.

The District is a public sewer utility formed by the voters of Boone County in 1973 to work with the County Commission on wastewater planning. In 1985, due to growth and the increased need for quality wastewater management, the District acquired collection and treatment facilities from private companies, individuals and homeowners' associations. The District is regulated by the Missouri Department of Natural Resources (MDNR).

The flags are on your property because a request was made to Missouri One Call (MO1Call) to locate underground utilities. Each color represents a different utility or has a different meaning.
