About Us

Family-owned and Trusted since 1957

Welcome to Commercial Utilities, Inc., a beacon of excellence in the underground sewer and water industry and a proud hallmark of St. Paul’s cityscape. As the city’s oldest sewer and water company, our journey began in 1957, founded by the visionary Ralph Curella. Originally named Curella Sewer and Water, our humble beginnings were rooted in a deep commitment to quality and reliability.

In the early 1970s, a new chapter unfolded as Ralph Curella Junior took the helm, ushering in an era of expansion and innovation. Recognizing the evolving landscape of our business, he rebranded the company as Commercial Utilities, Inc., a name that resonated with our growing prowess in commercial projects. This strategic shift not only elevated our brand but also expanded our horizons, allowing us to serve a wider array of clients with the same foundational values of excellence and precision.

The legacy of commitment and quality service was seamlessly passed onto Ralph Junior’s son, Tony, who took over in 1998. Under Tony’s visionary leadership, Commercial Utilities, Inc. has continued to flourish, blending traditional craftsmanship with modern techniques. Tony’s tenure has been marked by a relentless pursuit of perfection, ensuring that each project we undertake is a testament to our unwavering attention to detail and dedication to customer satisfaction.

Today, as a third-generation family-owned business, we stand tall as an emblem of trust and expertise in the industry. Our rich history is not just a record of our past but a guiding light for our future, as we continue to innovate and lead with the same passion and integrity that Ralph Curella instilled over six decades ago. At Commercial Utilities, Inc., we don’t just lay pipes; we build the lifelines of communities, ensuring every project we undertake is a part of our enduring legacy of excellence.
