America’s Aging Service-Line Problem

Across the United States, millions of homes remain connected to public water mains through lead service lines, legacy pipes installed decades ago, before the health risks of lead were fully understood. The EPA estimates that approximately 9 million lead service lines remain in use nationwide, posing an ongoing public health concern. Often buried beneath streets and lawns, these pipes are easy to overlook, yet they remain a significant pathway through which lead can enter household drinking water.

The scale of the problem reflects the age of America’s water infrastructure. Many systems were built in the early 1900s, when lead was valued as a durable, malleable plumbing material. Cities such as Chicago, Cleveland, and Milwaukee used lead extensively, leaving extensive underground networks that continue to serve some residents today.

Replacing these pipes has been challenging for several reasons. Responsibility is often divided between municipalities and property owners: utilities typically manage the public portion of a service line, while homeowners are responsible for the private section connecting to the house. This split can create confusion over costs, coordination, and who must arrange the replacement.

The problem is further complicated by incomplete municipal records. Many communities do not have reliable inventories showing which properties are connected to lead pipes. Identifying and documenting these lines therefore requires extensive work involving utility crews, mapping systems, and information from residents.

Although awareness has increased following crises such as Flint, replacement efforts remain a major undertaking. Without sustained federal funding, many communities, particularly low-income and rural areas, face difficulties keeping pace. Lead contamination testing across New York City can help identify potential concerns in drinking water, while broader infrastructure programs are needed to address the pipes themselves. Ultimately, replacing aging service lines is both an engineering and an equity challenge that requires long-term investment, coordinated planning, and public engagement.

The Cost and Timeline of Full Replacements

Eliminating every lead service line in the United States is a monumental but necessary undertaking. Experts estimate the total cost to range from $30 billion to $60 billion, depending on regional labor rates, pipe lengths, and soil conditions. For individual properties, replacement typically costs between $4,000 and $15,000. Because lead service lines can run dozens of feet underground, excavation must often extend into private yards and basements, adding further expense and coordination.

Funding sources include federal and state programs like the Drinking Water State Revolving Fund (DWSRF) and the Bipartisan Infrastructure Law, which allocated $15 billion specifically for lead service-line removal. However, even with this unprecedented investment, experts warn that complete national replacement could take 20 to 30 years at the current rate of progress.

Replacing lead pipes is not as simple as digging and swapping materials. Each project involves identifying line ownership, securing homeowner consent, closing water service temporarily, excavating safely around utilities, and restoring landscaping or pavement afterward. Municipalities must also balance these projects with other critical infrastructure needs like sewer repairs, roadwork, and water main upgrades.

Some cities have proven that rapid progress is possible. Madison, Wisconsin, completed full replacement in 2011 through strong local mandates and cost-sharing programs. Lansing, Michigan, followed suit with a decade-long campaign that removed every known lead line. Their success demonstrates that proactive planning and community involvement can overcome financial and logistical barriers.

Nationwide, achieving full replacement will require not just money, but transparency, prioritization, and accountability. Without these, the timeline will stretch far beyond a generation leaving millions of Americans still at risk from an invisible contaminant that should have been eliminated decades ago.

Mapping Major Cities with Ongoing Line Replacements

Tracking the progress of lead service-line replacement across major cities reveals a patchwork of progress and delay. Chicago, for example, holds the largest concentration of lead service lines in the nation estimated at more than 400,000. Despite this, large-scale replacement only began recently, supported by new state and federal funding.

Pittsburgh, Cleveland, and Milwaukee have launched ambitious removal programs, prioritizing schools, childcare centers, and low-income neighborhoods where the risk is highest. Newark, New Jersey, once considered a hotspot of contamination, completed the replacement of more than 20,000 lines in under three years proving that decisive political leadership can make a difference.

To increase transparency, the EPA’s Lead Service Line Inventory Rule now requires every water utility in the country to identify and publicly share which properties may still have lead connections. This mandate, enacted in 2024, represents a major step toward national accountability. Cities are building interactive maps that allow residents to check if their home or street is affected.

At LeadWaterWatch, we compile this information from city databases, federal filings, and local reports to provide a unified national picture. Our upcoming interactive map will show where replacements are ongoing, completed, or yet to begin empowering residents, journalists, and policymakers with real-time data.

By visualizing progress, mapping turns abstract statistics into human stories. It highlights which neighborhoods are being protected first and which are still waiting. The more transparent these maps become, the more communities can hold leaders accountable for the promises made in the pursuit of safe, lead-free drinking water.
