McCarrons Water Treatment Plant Improvements

In January, 2021, SPRWS began an exciting project aimed at upgrading the McCarrons water treatment plant.

Since the mid-1910s, the McCarrons Water Treatment Plant has been providing reliable, quality drinking water to residents of Saint Paul and neighboring communities. Though the facility has been expanded on several occasions, much of the infrastructure which supplies our customers with water is nearing 100-years in age. Despite its age, the treatment plant continues to perform well and produce high quality drinking water for 450,000 people in St. Paul and the surrounding communities.  In fact, the McCarrons water treatment plant is one of only 31 facilities in the nation to have received the Presidents’ Award for Water Treatment from the Partnership for Safe Water. Our staff is proud of the role that our exceptional water quality plays in maintaining public health.

While current water quality remains exceptional, SPRWS is proactively looking towards the future and planning to make significant improvements to the McCarrons water treatment plant. These improvements will position SPRWS to continue providing high quality water far into the future. Most of the changes to the facility will be targeted at improving reliability and flexibility and will enable the utility to continue to meet the needs of customers in the future. The utility has a longstanding history of proactively investing in infrastructure. Those investments have made the utility one of nation’s best, and modern investments build on that tradition. 

Overall, SPRWS expects to replace roughly 2/3rds of the existing treatment process with more modern technology.  We are also considering the potential addition of ozonation, a treatment process which may offer significant benefits for our customers.

While this project is still in its early stages, a significant milestone was reached when SPRWS signed a contract with Jacobs Engineering to perform the design and construction services for the project.

SPRWS staff will provide updates on this webpage as the project progresses.

Lead Service Replacements, Payment Plans, and Free Testing

Lead Service Replacements

We own and maintain the portion of the water service in the street right of way and we replace that portion of the service in conjunction with street maintenance projects, when a homeowner replaces their lead service in private property, or during targeted replacement projects.

The property owner owns and is responsible for maintenance and replacement of the service within private property. If a property owner outside a street maintenance project elects to replace their portion of the lead service line, we will replace the portion within the right of way at no cost to the property owner.

To find out if your water service line contains lead, look up your address on our service material map or call our engineering service desk at 651-266-6270

Voluntary Assessment Program (Payment Plan)

We offer an assessment program for Saint Paul residents that allows for the costs of lead service line replacement work in private property to be assessed and collected through property taxes over time. If a property owner outside a street maintenance project elects to replace their portion of the lead service line, we will replace the portion within the right of way at no cost to the property owner.

For more information on the assessment program, refer to our lead replacement packet (PDF - 1.39 MB) or call our engineering service desk at 651-266-6270.
