Lead Service Lines in San Bernardino, CA

San Bernardino's water is served by 40 different systems, with the City of San Bernardino and San Bernardino Valley Water District serving the largest populations of 214,665 and 109,608 residents respectively.

What we know about lead service lines here

Lead service lines are pipes that connect the water main in the street to your home. Water can pick up lead as it travels through these pipes, especially in older homes. Currently, none of the major water systems in San Bernardino have reported confirmed lead service lines in their inventories. However, most systems have not yet completed full inventories of their service lines—many records are incomplete or unknown.

This doesn't mean lead service lines don't exist here. It means they haven't been documented yet. San Bernardino has neighborhoods built in the mid-20th century when lead pipes were still in common use, so older homes in particular may have lead service lines even if they're not on official lists.

How to find out if your home is at risk

Your water utility maintains records of service line materials. Contact your local water system directly and ask:

  • Is my service line made of lead, galvanized steel, or copper?
  • Do you have records for my address?
  • If records are unclear, what testing options do you offer?

The City of San Bernardino and San Bernardino Valley Water District should be able to answer these questions. If you're outside these main systems, identify which of the 40 systems serves your area and reach out to them.

What you can do now

Even without knowing your service line material, you can reduce lead exposure:

  • Run your tap before drinking. Let water flow for 30 seconds to 2 minutes if the tap hasn't been used in 6+ hours.
  • Use cold water for cooking and drinking. Hot water dissolves lead faster.
  • Consider a point-of-use filter. Look for NSF/ANSI 53 certification, which removes lead.

If you have young children or are pregnant, talk to your pediatrician or doctor about lead testing—your utility or county health department can provide guidance.

Next steps for residents

  • Contact your water utility and request your service line material records
  • Ask if your system has a lead service line replacement program
  • If records are unavailable, ask about water testing at your home
  • Run your tap before using water for drinking or cooking until you know your service line type

Common questions

Does San Bernardino have lead in the water?

Lead gets into water through lead service lines (pipes connecting your home to the street) and old plumbing. San Bernardino's water systems have not reported confirmed lead service lines in their current inventories, but many records are incomplete. Your risk depends on your home's age and service line material.

How do I know if my house has a lead service line?

Contact your local water utility—for most of San Bernardino, that's the City of San Bernardino or San Bernardino Valley Water District—and ask if they have records of your service line material. If records are missing, they may offer water testing or a visual inspection.

Is it safe to drink tap water in San Bernardino?

San Bernardino's water systems treat water to meet safety standards. However, if you have a lead service line, lead can enter your water at home. Running your tap for 30 seconds before drinking and using cold water for drinking and cooking reduces exposure.

What should I do if I'm worried about lead and my kids?

Talk to your pediatrician about lead testing. You can also contact your water utility about water testing at your home and ask about lead service line replacement programs that may help you.
