Lead Pipe Replacement Programs

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. The programs are either initiated by DC Water or by the customer. Read below to find out more about the programs and determine which would be right for you.

Check our map for information about the material of your service pipe.

DC Water Initiated Lead Replacements

Each year, DC Water replaces lead service pipes in conjunction with other construction projects including small diameter water main replacement projects (SDWM) and CIPERR By-Block (CBB) 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.

If both portions are lead, and construction work isn’t planned,
the homeowner is responsible for all private-side costs..

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

Customer Initiated Lead Replacements

In areas where no construction is planned, DC Water offers two programs to help customers replace there lead service lines, Private-side only replacements and voluntary full replacements. These programs allow customers who wish to replace there lead service with assistance from DC Water.

Private side Only Lead Replacements

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.

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

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

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

If your private side pipes are lead but the public spaces pipes are not, you are eligible for this program. Property owners can apply with the Department of Energy and Environment (DOEE).

Voluntary Full Lead Replacements

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

If both the public and private portions of the 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 DC Water initiated 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
