Lead Pipe Replacement Occurs During Construction Projects or By Request

Like most older cities, homes built before the 1980's were typically built with a lead service line—the pipe that connects the city water supply to your household plumbing. DC Water operates several programs for lead service line replacement.

DC Water always pays for lead pipe replacement in public space, and new District funds help customers pay for replacement on private property.

Construction Project Lead Replacements 

If both portions are lead, and work is planned,
the District will pay for 100% of private-side costs.

Each year, DC Water replaces lead service pipes in conjunction with other construction projects. These projects include water main replacements, emergency repairs and District Department of Transportation (DDOT) projects. DC Water will contact you if there are any planned projects in your neighborhood

During these projects, replacement on private property is FREE for all residents—regardless of income. We strongly encourage property owners to take advantage of this opportunity so that we can replace the entire lead pipe at one time. Questions about planned projects, or the replacement agreement for these projects should be sent to

Private-side Only Lead Replacements

If only the portion on private property is lead, 
the District will pay for 50%, 80%, or 100% of private-side costs. 

For residents with lead pipe on private property, and non-lead pipe in public space, the Lead Pipe Replacement Assistance Program (LPRAP) uses District funds to provide a free or discounted replacement.

Each property owners can receive a 50% discount, regardless of income. Some residents will qualify for 80% or 100% coverage depending on household size and income.

Qualifying properties are listed here. Property owners can apply with the Department of Energy and Environment (DOEE).

Voluntary Full Lead Replacements

If both portions are lead, and NO work is planned,
the homeowner pays for private-side costs. 

If both the public and private portions of service line are lead, and no capital improvement projects are planned for the neighborhood, customers can enroll in the Voluntary Replacement Program. Similar to replacement during construction projects, DC Water will pay for all work in public space, and coordinate work so both portions are replaced at the same time. The property owner pays for work on private property. For more information visit the voluntary lead service replacement page, or email
