In 2021, the federal government enacted new regulations to mitigate exposure to lead from water service lines. A service line is the pipe that moves water from the city’s water system into homes and businesses. The city owns the water service line from the water main (typically under the street) to the meter, and the customer owns the water service line from the water meter into the home or building.
To comply with the new regulations, all drinking water providers in the U.S. must inventory their water service lines to identify and develop a plan to replace any made of lead. Some service lines made of galvanized steel may also require replacement.
The city is not aware of any lead service lines in our public system, and the water leaving our treatment plants does not have lead in it. However, customer-owned water service lines that connect to older homes and businesses might. The city has started a program to identify if lead is present in water service lines to every home and business in Boulder.
To do this, we need our customers’ help to identify what their property’s water service line is made of.
