The Sanitary District maintains detailed maps and records of the sanitary sewer system.  These records include not only maps of the public sanitary sewers, but also sketches of almost all building sewers constructed in the District since 1937.  Building sewers are owned and maintained by the property owner from the building to the connection with the public sewer.  Limited information is available for building sewers constructed prior to 1937 or for areas where sewers were constructed outside of the District and later annexed.  A property owner can obtain a copy of the sketch, when available, by contacting the Planning and Construction Department at 309-272-4844.  If any repairs or modifications are made to the building sewer, the owner is requested to contact the Planning and Construction Department to allow the District to update our records.

In addition to building sewer records, the District maintains a file of sanitary sewer easements.  You can also contact the Planning and Construction Department to determine the location of an easement or to inquire about any other available records of the sanitary sewer system.

Wastewater leaves residences and other buildings through 4-inch and 6-inch diameter building sewers. These building sewers are owned by the property owner to the point of connection with the publicly owned sewer. Maintenance and repair of the building sewer is the responsibility of the individual property owner. This includes both the portion on private property and the portion located beneath the public right-of-way (sidewalks and streets)
