Site work for a water / sewer project in Dubuque, Iowa. Conceptual plans call for site work for a water / sewer project.

In 2020, a condition report was completed on the primary force main system that runs between the Cedar Street lift station to the Terminal Street lift station to the W&RRC. Approximately 80% of all wastewater travels to the W&RRC for treatment via the force main leaving the Terminal Street lift station. The high points in this force main pipe network contain air releases that allow hydrogen sulfide gas to escape the pipe so that they don’t develop a concentrated pocket inside the pipe which can lead to accelerated deterioration and pipe failure. Several of these air releases are no longer functional and need to be replaced. These locations include 4th Street, 3rd Street, the valve house, CN rail yard, South Port levee, Julien Dubuque Drive and the softball fields. Funding in each of the fiscal years provide for purchasing a second air release for all air release locations on the force main system so that each location can be swapped out on an annual basis for maximum system performance and the replaced air releases can be cleaned and rehabilitated as time permits so that it is ready to be put back into service in the upcoming months. This project is included in the city's fy 2024-2028 Capital Improvement Program. As of July 18, 2023, further details regarding design and construction timelines have not been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
