Lead Service Lines in CTWC - Unionville System
What you need to know
CTWC - Unionville System serves about 14,700 people in Connecticut. Like many older water systems, lead service lines—the pipes connecting homes to the main water supply—may be present in this area.
A lead service line is a potential health concern because lead can leach into drinking water, especially if the water is corrosive or treatment isn't optimized. The only way to know if your home has one is to check your own property or contact your water utility directly.
What this utility has reported
As of now, CTWC - Unionville System has not published a complete inventory of lead service lines in its service area. This doesn't mean lead lines aren't there—it means the utility hasn't yet finished mapping them, shared those findings publicly, or both.
Connecticut law requires water utilities to maintain and eventually share this information. If you're concerned about lead exposure in your home, you don't need to wait for a utility-wide inventory to take action.
How to find out about your home
Contact your water utility directly. Ask them:
- Do you have a lead service line on your property?
- Have you had your water tested for lead?
- What's your timeline for finishing a full service line inventory?
You can also:
- Hire a licensed plumber to inspect the pipe entering your home.
- Request a free or low-cost water test through your local health department.
- Have an independent lab test your water if you want a second opinion.

Frequently asked
How do I know if I have a lead service line?
Contact your water utility and ask about your address. You can also have a plumber inspect the pipe where it enters your home—lead pipes are soft, dull gray, and leave a mark if you scrape them with a coin.
Is lead in drinking water dangerous?
Lead exposure can affect the brain and nervous system, especially in young children. Talk to your pediatrician or the CDC for health concerns. The good news: treatment and testing can reduce risk.
What should I do if I have a lead service line?
Flush your pipes before drinking, consider a certified water filter, and contact your utility about replacement options. Some utilities offer financial help or have replacement programs.
