Carollo Engineers

For more than 90 years, Carollo Engineers has been dedicated exclusively to water and wastewater solutions. Water is not just part of what we do—it’s all we do. We see more in clean water: more than the science, the planning, and the design. We see the families and communities we serve and the fragile ecosystems we protect. That perspective drives us to deliver innovative, sustainable solutions that improve performance, minimize risk, reduce costs, and ultimately create healthier environments. As an environmental engineering firm, we specialize in the planning, design, and construction of water and wastewater facilities. Our sole focus on water means our clients benefit from unmatched expertise and collaboration, and our employees find purpose in work that changes lives and shapes a better world. Since 1933, our commitment to water has remained unwavering. We come to work every day passionate about creating a brighter, more resilient future for our communities and our planet.
