Lead Service Lines in Fresno's Water System
The City of Fresno serves approximately 545,716 people. Like many California water systems, Fresno relies on surface water sources.
What you need to know
Lead service lines (the pipes that connect the main water line under the street to your home) are a legitimate concern in older cities. If your home was built before the 1980s, there's a chance your connection could contain lead. Even trace amounts can be a health risk, especially for young children and pregnant people.
Fresno has not yet completed a full inventory of lead service lines in the system. This means the utility doesn't have a comprehensive public list showing which addresses have lead pipes, which have safe alternatives, or which are still unknown.
Why this matters
Without a complete inventory, both you and the water utility lack clear information about your specific risk. The federal Lead and Copper Rule requires all water systems to identify and eventually replace lead service lines, but progress varies widely. Fresno is still in the data-gathering phase.
What Fresno is doing
Water systems across California are under increasing pressure to map their lead service lines, especially following state and federal funding opportunities. Check the City of Fresno's official website or contact the water department directly to ask about their current inventory progress and timeline.
Protect your water right now
While Fresno's inventory is being developed, you can take steps today:
- Have your water tested for lead by a certified lab (usually $20–50). The utility can recommend local labs.
- Flush your pipes each morning by running cold water for 30 seconds to 2 minutes before drinking or cooking.
- Use cold water for drinking and cooking. Hot water leaches lead faster.
- Ask your utility or a plumber whether your service line is likely lead based on your home's age and neighborhood.
If you have concerns about health effects, contact your pediatrician or the CDC.
Next steps for residents
- Contact the City of Fresno Water Department to ask about the lead service line inventory and when results will be public.
- Request a free or low-cost water test through the utility.
- Have a plumber inspect your service line if your home was built before 1980.

Frequently asked
Does Fresno have lead in the water?
Fresno treats its water to reduce lead, but the risk depends on your home's service line and indoor pipes. The city is still inventorying which properties have lead service lines. A water test will tell you if lead is present in your specific home.
How do I know if my house has a lead service line?
Fresno's complete inventory is not yet public. Contact the City of Fresno Water Department or hire a plumber to inspect the pipe between the street and your meter. Homes built before the 1980s are at higher risk.
Is it safe to drink Fresno tap water?
Fresno's water is regularly tested and treated. However, lead risk depends on your home's pipes, not just the main water system. Get your water tested, flush pipes before use, and use cold water for drinking and cooking to reduce exposure.
Will Fresno replace my lead service line?
Water systems are required by federal law to eventually replace lead service lines, but timelines and cost-sharing vary. Contact the City of Fresno Water Department to ask about replacement programs, funding, and whether your address is a priority.
