Frequently Asked Questions

The Village has storm sewers and sanitary sewer systems.

Storm sewers are designed to collect and direct storm water to storage areas or to creeks. Storm water is not treated. You should never pour unwanted chemicals or other foreign substances in the storm sewer.

Sanitary Sewers provide direct waste pumping stations that pump to the treatment plant for treatment and discharge to the West Fork of the North Branch of the Chicago River.

Section 16-7 of the Municipal Code states that all repairs and maintenance of the services lines from the public sewer, including the connection to the public sewer, to the premises served and in the sanitary sewer system of the building served shall be made by and at the expense of the owners of the premises served.

Always contact the Public Works Department first at 847-317-7245 (Monday - Friday, 7 a.m. to 3:30 p.m.). After 3:30, call the non-emergency number for the Deerfield Police Department at 847-945-8636 and they will direct your call to the Sewer Department.

Usually this occurs in the winter time as the trap in the floor drain dries out, allowing the sewer odor to enter the house. To fix the problem, add water to the floor drain and the smell should go away. If this method doesn't work, contact the Public Works Sewer Department at 847-317-7245 for further assistance.

Sewage is pumped to the Deerfield Wastewater Reclamation facility. The sewage is treated and disinfected and discharged into the West Fork North Branch of the Chicago River. In many cases, the discharged water is cleaner than the water in the river.
