Water Infrastructure Planning & Design
Infrastructure is critical to all water, wastewater, and stormwater systems. However, it’s also one of the most resource and maintenance intensive investments that utilities make. Carollo is committed to working with our clients on planning and designing efficient, sustainable infrastructure as well as identifying cost-effective maintenance and retrofit options that support the overall health of the utilities.

A leader in water infrastructure since 1933
In addition to aging, water assets across the country are now being affected by changes occurring in local watersheds as a result of shifting consumption trends and land use and extreme weather events. Consistently inspecting, repairing, and replacing these assets places significant burdens on utilities and the communities they serve. This is why the U.S. Environmental Protection Agency (EPA) now requires water infrastructure to be not only reliable in operations and capacity, resilient, and maintained in serviceable conditions but also managed to uphold long-term sustainability. No partner in the water and wastewater sector is more aware of these changes and challenges than Carollo. With cities, public utility districts, and community groups, we’ve built and grown alongside the infrastructure that continues to serve millions of Americans every day.

More than 1,000 projects planned, designed, and executed
We’ve supported the planning, design, and construction of water, wastewater, and stormwater infrastructure projects that included the following efforts:
- Assessment, rehabilitation, and design of over 700 miles in sewers.
- Engineering solutions for pipelines and pump stations that handle flows as little as less than 1 million gallons per day (mgd) to over 650 mgd.
- Pipeline resiliency designs that can mitigate potential seismic events.
