The City provides drinking water to residential, commercial, industrial, and private utilities covering over 40 square miles across Will and Kendall Counties. The City’s water distribution system consists of 6 water pumping stations, 3 underground storage tanks, 2 standpipes, 5 elevated tanks, and 580 miles of water main. The age of the system ranges from the 1880s to the present day and sections of the system are rapidly deteriorating. The deterioration of the system results in a higher frequency of water main breaks. These breaks have a significant impact on the City’s expenses because the City not only pays for the labor, equipment, and materials to make the repairs, but also must pay for the water that is lost.
In order to address the declining condition of the water system and to maintain current levels of service, the City has developed a 5-Year Watermain Rehabilitation Program. For a map of the proposed project locations click here. The goal of the program will be to replace 1% (approximately 5 miles) of water main annually. Projects in the program were selected based upon the frequency of water main breaks, criticality, water quality, and fire flow requirements. Rehabilitation techniques such as traditional open cut replacement, horizontal directional drilling, and water main lining were evaluated for cost effectiveness and suitability for the project locations. Based on a review of the conditions, sizes, and ages of existing pipes, it was determined that traditional open-cut replacement will be the most feasible and cost effective means to improve fire flow and reduce water main breakage for the majority of the water main rehabilitation projects. Lining was recommended for water main rehabilitation projects that had limited service line connections and did not require an increase in pipe size.
Construction of the identified projects is dependent upon available funding. It may be necessary for the City to modify the program based upon system needs.
