Saint Paul Regional Water Services (SPRWS) provides water to approximately 450,000 customers. To facilitate this, we operate and maintain a complex system of water supply, treatment, and distribution infrastructure. Our system provides Saint Paul and many surrounding communities with approximately 40 million gallons of high quality treated water on a daily basis. Below you will find detailed information about particularly important aspects of our work and projects we'd like to highlight to our customers.
SPRWS restores, replaces, and installs several miles of water main each year to help maintain the water distribution system that delivers water from our treatment plant to homes and businesses. Our Water Construction Projects page provides information on planned water main construction and lead service line replacement projects.

Our Water Meter Register Replacement page explains what a water meter register is, why it is being replaced, and what to expect during installation. Customers selected for replacement will receive a letter from SPRWS with instructions to schedule an appointment. Visit the Water Meter Register Replacement page for more information.
The McCarrons Water Treatment Plant, a century-old establishment in Saint Paul, is undergoing significant enhancements to fortify its commitment to delivering clean, high-quality drinking water to the community. Recognized with the esteemed Presidents' Award for Water Treatment, our mission is to modernize aging infrastructure, boost operational efficiency, and integrate state-of-the-art technologies such as ozonation. We're not only preserving a legacy but securing the future of water resources for over 450,000 customers.
Most lead services were installed in homes built prior to 1926. There were also a small percentage of homes built between 1942 and 1947 that 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 to interpret the results of their tests. Eliminating these lead service lines is the best long-term solution to the problem of lead in drinking water.
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
