Inflow & Infiltration (I&I) FY25-26 - SR-II-25 - City of Jacksonville

This project will represent the City's ongoing effort to reduce infiltration of groundwater and inflow of stormwater into the sewer collection system which usually is attributable to aging infrastructure that needs maintenance or replacement. Reduction of I&I translates to reduced operational and maintenance costs as well as reducing the risk of sewer system overflows (SSOs) during periods of high rainfall. The first phase of this work will involve identifying sources of I&I by one or more of the following: flow monitoring, smoke testing, and video inspection. These sources will be prioritized based upon severity and location along with other sources discovered via other utility projects and through the work of the City's Utilities Maintenance Division. Once I&I sources are identified and prioritized, a project will be undertaken to correct as many of the deficiencies as the available budget will allow. It is expected that the project will involve several repair and rehabilitation methods including but not necessarily limited to, complete manhole-to-manhole line replacements, spot repairs, manhole repairs and Cured-In-Place Pipe Lining (CIPPL). This project is in included in the City of Jacksonville FY 2023-2032 Capital Improvement Plan (CIP). As of July 13, 2022, further details regarding design and construction 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.
