President Biden on Tuesday announced $2.6 billion in funding to replace all lead pipes in the United States as part of a new EPA rule that will require lead pipes to be identified and replaced within 10 years using the new funding from the Bipartisan Infrastructure Act.
Generally the pipes inside your home and the service line (from the property line to your house) are your responsibility. So I would assume this is for Municipality owned pipes.
My city is currently having residents report to the city what thier service line is made of, by having us make assessment following thier instructions and sending pictures of the water line connected to the water shutoff valve. While they’re not currently replacing them for us, they are helping residents connect with reputable plumbers.
