Lead Service Lines in Worcester, MA

Worcester's water system serves about 208,000 people through 22 different water utilities. The largest provider is Worcester DPWP, Water Supply Division, which serves roughly 206,500 residents.

What we know about lead service lines in Worcester

Massachusetts requires water utilities to maintain an inventory of lead service lines—the pipes that connect homes to the main water lines under the street. These inventories are still being compiled across the state, so complete data isn't always available yet.

For Worcester's main utility (Worcester DPWP), the lead service line inventory status is currently unknown. This doesn't mean there are no lead lines; it means the utility is still in the process of identifying and documenting them. This is normal for many communities in Massachusetts.

Why this matters

Lead service lines are the most common source of lead in drinking water. Even small amounts of lead exposure can affect children's development and learning. If you have an older home in Worcester (built before the 1950s), lead service lines are more likely—though they can exist in newer homes too.

How to find out if your home has a lead service line

Your water utility keeps records about service lines for individual addresses. The first step is to contact Worcester DPWP directly and ask about your specific property.

You can also:

  • Ask a licensed plumber to inspect your home's pipes
  • Request a free or low-cost water test through your local board of health
  • Check if your utility has posted its lead service line inventory online

If you find a lead service line

You don't need to panic, but you should take action. The EPA recommends flushing your tap for 30 seconds before drinking or cooking if water has been sitting in pipes overnight. Using a certified lead-removing water filter is also an option while you plan a replacement.

Many communities offer rebates or financing to help residents replace lead service lines. Contact Worcester DPWP to ask about available programs.

Next steps for residents

  • Call your water utility (Worcester DPWP, Water Supply Division) and ask about the lead service line at your address
  • Request a water test through the City of Worcester Board of Health
  • Visit the EPA's lead website for immediate steps to reduce exposure at home
  • Consult your pediatrician if you have young children and are concerned about lead exposure
