Susquehanna Water Update (10/8/26): What Happens Next
Susquehanna Blended Water Expected to Reach Households by Friday. Residents can use DPW’s interactive tool to see if their address is within the expected service area.
Susquehanna River water is not yet in the City’s water distribution system. DPW expects Baltimore-area households to begin receiving a blend of Susquehanna water and water from the City’s reservoirs by Friday afternoon, Oct. 9.
On Monday, Oct. 5, the Baltimore City Department of Public Works (DPW) activated the system to begin bringing water from the Susquehanna River into the City’s current water supply. The water must travel nearly 40 miles to reach the City’s Montebello Water Treatment Plants.
The City is not switching to 100% Susquehanna River water. The initial blend is expected to contain approximately 20% to 40% Susquehanna River water, mixed with water from the City’s reservoir system. Because Susquehanna River water will be gradually blended with reservoir water, significant changes in water quality are not expected.
Once the Susquehanna water reaches the Montebello Water Treatment Plants, DPW will continue to treat and test the blended water to ensure it meets applicable drinking-water standards before it enters the water distribution system.
