Major Projects
AlexRenew’s major projects are a vital investment in the public health of the community we serve, and a commitment to preparing for a future with continued access to clean water and healthy waterways.
RiverRenew
RiverRenew is the largest infrastructure initiative in the history of Alexandria. RiverRenew includes multiple projects that consist of a new tunnel system and upgrades to Alexandria's wastewater treatment facility. Once complete, it will prevent over 120 million gallons of combined sewage from entering our waterways each year.
Commonwealth Interceptor Study
AlexRenew is studying a portion of the Commonwealth Interceptor — a separate sanitary sewer that is owned and operated by the authority — to evaluate alternatives to mitigate capacity issues in the interceptor due to excess infiltration and inflow.
Alternatives being evaluated include:
- Improving the existing stormwater system capacity to minimize flooding (City project)
- Disconnecting rain leaders from the separate sanitary sewer system (City project)
- Eliminating discharges from foundation drains and sump pumps into the separate sanitary sewer system (City project)
- Removing cross-connections (City project)
- Sealing manhole covers on separate sanitary sewers in low-lying areas (City project)
- Rehabilitating existing separate sanitary sewers, manholes, and laterals (City project)
- Increasing the capacity of Commonwealth Interceptor (AlexRenew implemented project)
