Lead and Household Water

What is SPRWS doing about lead?

Treatment

Lead can leach from lead service lines or lead solder in the home. To reduce leaching, we treat our water by constantly monitoring and adjusting the pH and alkalinity levels. This process, called corrosion control, creates a protective scale on the inside of the pipe between the water and the lead. Our treatment processes are in strict compliance with the Safe Drinking Water Act, Lead and Copper Rule, and Minnesota Department of Health regulations.

Our lead corrosion control treatment process:

• Add lime and sodium hydroxide to the water to increase the water’s pH levels so that the water is minimally corrosive to lead
• Add chlorine as a disinfectant for added protection
• The two water chemistry adjustments work together to form a protective film covering surfaces that have lead which minimizes how much lead can enter the water
• We then check the effectiveness of this process per regulations

Testing

We test our water for lead often. The U.S. Environmental Protection Agency (EPA) requires the testing we do as part of the federal Safe Drinking Water program.

Investigating Complaints

We take all water quality complaints and issues seriously. If you are experiencing an issue, contact us at 651-266-6350.

We respond to customer complaints about water quality, such as colored water or taste and odor concerns. We will flush the system in problem areas and test the water if there are taste and odor or health complaints.

Free Lead Testing for Customers

What can I do to reduce lead in my water?

The best way to reduce lead is to remove lead water service lines and replace them with copper. See Lead Service Line Replacements and Payment Plans below for more information.

Other actions you can take include:

• Confirming if you have a lead service by looking up your address in our service material map, calling SPRWS engineering at 651-266-6270, or performing a "scratch test" on the pipes leading to your water meter.
• Testing your water for lead for free by picking up and returning a collection bottle from our customer service staff at 1900 Rice Street.
• If you have a lead service, taking proactive steps to reduce your risk:
  • Do not drink or cook with water that has collected in your plumbing for more than six hours
  • Clear water lines by running cold water for 3-5 minutes before use
  • Run the water before you drink from any faucet in the house
  • Use cold water for cooking, drinking, and making baby formula - hot water dissolves lead more quickly
  • Clean faucet aerators at least once a month
  • Treat your water using a pitcher or filtration system that is NSF certified for lead

Lead Service Line Replacements and Payment Plans

We own and maintain the part of the water service in the street right-of-way. We replace that part of the service during some street maintenance projects. The property owner owns and is responsible for maintaining and replacing the service within private property.

We are developing a 10 year plan to replace all lead water service lines in our service area (both the public and private side of the service) at no cost to property owners. The program will begin in full in 2023. For more information, visit our Lead Free SPRWS program page.

If you have lead in your service line and do not want to wait for the Lead Free SPRWS program to replace it, you also have an option. Our assessment program for Saint Paul residents allows the costs of such replacement work to be assessed and collected through property taxes. For information on the assessment program view our lead replacement packet (PDF - 396KB) or call the SPRWS engineering division at 651-266-6270.

Free Lead Testing

Most lead services were installed in homes built before 1926. A small percentage of homes built between 1942 and 1947 also have lead service lines. These homes are at higher risk of lead leaching from the pipes. We offer free lead testing for these customers and help them interpret the test results. Replacing these lead service lines is the best long-term solution to the lead in drinking water problem.

Lead testing kits are available for customers at the customer service desk at:

1900 Rice St
Saint Paul MN, 55113
Monday - Friday from 8:00 am - 4:30 pm

For more information call customer service at 651-266-6350.

If you live outside our service area, a private laboratory can test your household water. Contact the Minnesota Department of Health for a list of certified laboratories.
