Lead Service Lines in SCWA MATHER-SUNRISE
SCWA MATHER-SUNRISE serves about 30,825 people in California. Like all water systems in the US, it is required to create and maintain an inventory of lead service lines—the pipes that may carry water from the main line under the street into your home.
What you need to know
A lead service line is a potential source of lead in drinking water. Lead is a toxic metal that can harm health, especially in children and pregnant people. The good news: lead in water is preventable through testing, filtration, and pipe replacement.
Current inventory status: SCWA MATHER-SUNRISE has not yet completed a full count of lead service lines in its system. This is not unusual—many water systems across the country are still in the early stages of mapping their pipes.
What this means for your home
You may or may not have a lead service line. The only way to know is to:
1. Contact your water utility directly and ask whether your address has a known lead, galvanized, or unknown service line. 2. Get your water tested if you're concerned. Testing is often free or low-cost through your local health department. 3. Use a filter certified to remove lead while you wait for more information or plan replacement.
Your water utility is required to share inventory data with you upon request, even if the inventory is incomplete.

Frequently asked
Does SCWA MATHER-SUNRISE have lead in the water?
The utility is still inventorying its service lines, so a full picture is not yet available. Lead in water comes from old pipes, not the source water itself. Contact the utility to find out if your home's service line is lead.
How do I know if my house has a lead service line?
Call SCWA MATHER-SUNRISE and give them your address. They should tell you what material your service line is made of, even if the system-wide inventory is incomplete. You can also hire a plumber to inspect the line where it enters your home.
Is lead service line water safe to drink?
Lead levels depend on water chemistry, pipe age, and how long water sits in the line. Some homes with lead lines have safe water; others don't. The only way to know is to test. If you're worried, use a pitcher or faucet filter certified for lead removal.
What should I do if I have a lead service line?
Have your water tested, use a certified lead-removal filter on drinking and cooking water, and flush your pipes by running cold water for 30 seconds to 2 minutes before use. Your utility may offer replacement assistance or rebates—ask about programs in your area.
