Look up your address, understand what DC Water's programs cover, and avoid the one mistake that can cost you the discount.

Water Lines & LeadEasy to check yourself20 minApplies to DCPrepared by PHI Group · Last reviewed

The water service line is the pipe that brings water from the main under the street into your house. In older parts of DC, some of those pipes are lead, and lead can get into drinking water. Finding out what yours is made of takes about twenty minutes, and DC Water has programs that can pay for replacement. This guide explains how to check, which program applies, and what to avoid.

Step 1: Look up your address

DC Water's Lead Free DC construction dashboard shows the status of your address. It will be one of five:

Blocks are chosen each year using a prioritization model, and construction is scheduled as funding is confirmed. The map is updated as blocks are added, so check back. If your status looks wrong, DC Water asks you to photograph the pipe where it enters the house and email lead@dcwater.com, or call 202-787-4044.

Step 2: Look at the pipe yourself

The utility's records are the starting point, not the last word. The service line usually enters the house in the basement or utility area, near the meter and the main shutoff. Lead is a dull gray, soft metal. Galvanized steel is also gray, but a magnet sticks to it. Copper is brown. EPA's advice is to ask your water utility, or a licensed plumber, to help identify the material. Do not scrape or file the pipe hard to test it.

Step 3: Know which program applies

Lead Free DC replaces lead lines on the schedule above. If your address is on the schedule, you do not need to hire anyone.

The Lead Pipe Replacement Assistance Program (LPRAP) is for homes where the private-side pipe is lead, galvanized or brass and the public side is not lead. DC Water's page says homeowners enrolled in the program receive a 100% discount on the private-side replacement. DC Water and DC's Department of Energy and Environment now run a single application, which DC Water says began in October 2026.

Two rules matter more than any other:

If you are hiring a plumber for this work, ask whether they are on the current Approved Contractor List before you sign anything.

Funding is the open question. DC Water's board was told in January 2026 that the District's funding for the program had been cut sharply and could run out within months. Ask DC Water whether funds are available before you plan around the discount.

Step 4: Protect yourself in the meantime

If you have, or may have, a lead line, EPA recommends that you:

EPA's action level for lead is 15 parts per billion. If more than 10 percent of tap samples at a water system exceed it, the system must take further steps. A test of your own tap can tell you more than the average.

Do it yourself or call a pro

Checking the dashboard and looking at the pipe are DIY jobs. Replacing the line is not. It involves digging, connecting to the meter, a permit, and in DC's program, approved paperwork before the first shovel. If your status says "contact DC Water for options" or you think the map is wrong, call DC Water first, then a plumber.
