SAN Jose Water Lead Service Line Inventory
San Jose Water serves approximately 1.04 million people across the San Jose area. Like all US water utilities, it is required by the EPA to identify and inventory lead service lines (LSLs)—the pipes that connect the public water main to homes.
What we know about San Jose Water's inventory
San Jose Water has not yet reported completion of a public lead service line inventory to the EPA. This does not mean the system has no lead lines; it means the utility is still in the process of identifying them.
The utility draws its water primarily from surface sources. As of our last update, detailed counts of lead, galvanized, or non-lead service lines were not publicly available.
Why this matters
Lead service lines are a known source of lead in drinking water, especially in homes built before 1986. Even at low levels, lead exposure—particularly in children—carries health risks. The only way to fully eliminate this risk is replacement.
If you live in San Jose Water's service area and your home was built before the 1980s, it is reasonable to assume your service line could contain lead, even if the utility has not yet confirmed it. A simple test of your tap water can tell you whether lead is present in your home's water.
What San Jose Water is doing
Your utility is required by law to complete its service line inventory and develop a replacement plan. You can contact the utility directly to ask about their timeline and whether they have specific information about your address.
Next steps for residents
- Test your water: Contact San Jose Water or your local health department for a free or low-cost lead test kit. Results will tell you if lead is in your home's water right now.
- Ask about your service line: Call San Jose Water and ask if they know whether your property has a lead, galvanized, or non-lead service line.
- Stay informed: Check back on this page or contact your utility for updates on their inventory progress.
- Health questions: If you have young children, talk to your pediatrician about lead exposure; the CDC also has guidance on lead and health.

Frequently asked
Does San Jose Water have lead in the pipes?
San Jose Water is still completing its inventory of lead service lines. Older homes (pre-1980s) are more likely to have lead pipes. A water test will show whether lead is in your home's water.
How do I know if my house has a lead service line?
Contact San Jose Water directly with your address—they may have records. You can also have a plumber inspect the service line connection at your home, or test your tap water to see if lead is present.
Is lead in water dangerous for kids?
Yes. Even low levels of lead exposure can affect children's development. Talk to your pediatrician about your home's water and consider testing. The CDC also has resources on lead safety.
What should I do right now about lead?
Get your water tested (contact your utility or health department), ask your utility about your service line, and if lead is found, discuss treatment or replacement options with them.
