Investing in the Future: Water Capital Improvements Plan

Archived News Release: January 27, 2023 - The City of Ann Arbor plans for investments in its infrastructure and assets through the annual updating of the Capital Improvements Plan (CIP). This six-year plan outlines and prioritizes the capital spending needed to maintain public infrastructure and continue to provide critical services to our community, such as providing safe drinking water, collecting and treating wastewater and capturing and conveying stormwater. The current CIP includes 500 projects and almost $1.2 billion worth of identified needs over the six-year period. Learn more about the CIP, why it's needed, and what's included at a2gov.org/CIP.

Long-term asset management planning, regulatory compliance, safety and risk of failure are all critical considerations when identifying and prioritizing capital improvement projects for utility infrastructure. Staff identifies project needs by assessing current conditions, evaluating maintenance history and considering community input and requests.

In the drinking water asset group, projects include replacement of mains with water quality issues or history of breaks, consolidation of parallel mains to decrease operations and maintenance costs, replacement of old, small mains with larger ones to service present needs, as well as significant, and much needed, capital improvements at the city water treatment plant.

In the sanitary asset group, several new projects are proposed at the wastewater plant, in addition to capital maintenance projects in the city sanitary sewer collection system. 

Recently added stormwater projects include infiltration projects in areas with good soil and slope conditions, in coordination with planned road work to provide cost efficiencies and minimize construction disruption. New studies and plans will help city staff better understand conditions of existing systems, determine future investment needs and assess the technical feasibility of planned improvements.
