Lead Service Lines in Middletown, Delaware

Middletown's water systems serve about 25,431 people across 14 water utilities. The largest is Middletown Water Department, which provides water to roughly 17,700 residents.

What we know about lead in Middletown's water

Lead enters drinking water through old pipes—mainly service lines that connect the main water line in the street to your home. Lead service lines are most common in homes built before 1986, though they can exist in any age of house.

Current inventory status: The water systems serving Middletown have not yet reported confirmed lead service lines to the state. This doesn't mean lead service lines don't exist in the area—it means either inventories are incomplete or lead hasn't been identified yet. Many utilities across Delaware are still completing their lead service line surveys, which are required under federal Safe Drinking Water Act rules.

What to do if you're concerned

If your home was built before 1986, there's a reasonable chance your service line could contain lead or be galvanized steel (which often corrodes and releases lead). The only certain way to know is to have it tested.

Contact your water utility to ask:

  • Whether they've identified lead or galvanized service lines on your property
  • What testing or replacement programs they offer
  • Whether you qualify for financial assistance (some utilities cover replacement costs)

The main utility in Middletown is the Middletown Water Department (PWSID: DE0000614). If you receive water from one of the smaller systems listed below, reach out to that utility directly.

If your home has a lead service line, using a certified water filter (NSF/ANSI Standard 53) can reduce lead in drinking water while you plan for replacement. For health questions, contact your pediatrician or the CDC.

Next steps for residents

  • Contact your water utility to ask about your service line status and testing options.
  • Check your home's age—if built before 1986, lead lines are more likely.
  • Request a free or subsidized lead service line test if your utility offers one.
  • Ask about replacement programs that might cover costs for removal and replacement.

Common questions

Does Middletown, Delaware have lead in the water?

Lead enters water through old pipes called service lines, not from the water source itself. Middletown's utilities haven't reported confirmed lead service lines yet, but many homes built before 1986 may have them. Contact your water utility to ask about your specific property.

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

The only reliable way is to have your service line tested. Ask your water utility (Middletown Water Department is the largest) whether they offer free or low-cost testing. Homes built before 1986 are at higher risk.

Is it safe to drink tap water in Middletown?

Middletown's water systems treat and monitor water for safety. However, if your home has a lead service line, lead can leach into your water. Use a certified water filter (NSF/ANSI 53) while you investigate your line's status, and contact your pediatrician with health concerns.

Can the city replace my lead service line?

Some utilities offer replacement programs or financial assistance. Contact Middletown Water Department or your specific water provider to ask whether they have grants, loans, or cost-sharing for lead service line replacement.
