The La Grange Park Department of Public Works sits in an easy-to-find location beneath the village's large water tower. On-call 24/7, the department is responsible for maintaining the public areas of the village of La Grange Park, including streets, sidewalks, parkways, lighting and public vegetation. In addition to those responsibilities, the department also monitors the sewer systems and potable water of the village. During winter, the department clears the streets and sidewalks of snow.
