Lead Service Lines in Watertown, South Dakota
What you need to know about your water system
Watertown Municipal Utilities serves about 23,230 people in Watertown, South Dakota. The utility draws water from groundwater sources.
Right now, the utility has not yet completed a full inventory of lead service lines in the system. This means they haven't yet identified which homes and businesses are connected to the water main through lead pipes—a step required under federal lead regulations.
An important note: The absence of an inventory doesn't mean there are no lead service lines. It means the work to find them is still in progress. Many water systems across the country are in this phase of compliance.
Why this matters for your home
A lead service line is the underground pipe that carries water from the main water line under the street into your home. If yours is made of lead, some lead can leach into your drinking water—especially in homes with newer plumbing or higher water pressure, or if your water is naturally corrosive.
Even small amounts of lead exposure can affect children's development over time. There is no safe level of lead in drinking water.
The good news: lead service line replacement is possible, and federal funding is now available to help pay for it.
What Watertown is doing
Watertown Municipal Utilities is in the process of identifying which service lines contain lead. Until that inventory is complete, the utility cannot provide specific information about your address.
Federal funding through the Bipartisan Infrastructure Law is available to help water systems replace lead service lines. Many systems, including those in South Dakota, are using these grants to accelerate replacement.
Next steps for residents
- Contact Watertown Municipal Utilities directly to ask about the status of the lead service line inventory and whether your address has been surveyed.
- Request your service line material. Even before a full inventory is complete, the utility may have records about your home.
- Have your water tested if you're concerned about lead. A simple test kit is inexpensive and can tell you if lead is present in your home's water.
- Talk to your pediatrician if you have young children and live in a home that might have a lead service line; they can advise on testing and next steps.
