The water supply section oversees the 10,200,000 gallon water reservoir at Touhy Avenue located just west of Milwaukee Avenue, the 5,000,000 gallon reservoir at Cumberland just north of Ballard, one overhead storage tank whose capacity is 250,000 gallons, and the 1,000,000 gallon stand tank located within the Four Flags Shopping Center.
The water supply section is ultimately responsible for the availability of water from Lake Michigan via the City of Chicago. The water plants' combined pumping capacity is 26,000 gallons per minute. The Village of Niles sells approximately 3.5 million gallons of water per day to the North Suburban Public Utility Company through a 1990 agreement.
Quite contrary to the old saying "Out of sight, out of mind," the Department of Public Services adheres to a proactive approach for infrastructure maintenance, especially for water and sewer.
