BACKGROUND:
In April 2021, the Water Utilities issued Bid 21-105, 2021 Naperville Heights Water Main Replacement. The project includes Webster Street, Main Street and 14th Avenue with north and south limits at Bauer Road and Ogden Avenue.
The purpose of the project is to replace aging and functionally deficient water main within the Naperville Heights neighborhood. The bulk of the existing water main is four-inch diameter and was built in the 1930s and 1940s. The water main will be replaced with eight-inch diameter water main which will increase fire flows in the area and provide a consistent level of service for residents of the neighborhood.
