Carollo Engineers has opened new offices in New York City and northern New Jersey to better serve municipal water and wastewater entities in the New York/New Jersey Metro area.

Big time water expertise for the Big Apple

The Northeast area of the country, and specifically, the New York/New Jersey Metro area, faces daunting water challenges. With Carollo’s singular focus on water, we bring proven solutions to help utilities address aging infrastructure, adapt to climate change, improve resiliency, and comply with new, more stringent regulatory requirements. The New York City Metro offices represent another East Coast foothold for the firm – adding to its offices in Massachusetts, Washington, D.C., Virginia, North Carolina, and Florida.

Notable projects along the Eastern Seaboard include pioneering some of the most innovative pipeline inspection tools for the Washington Suburban Sanitary Commission’s Water Main Condition Assessment Program and designing wastewater sludge thickening and dewatering facilities for two of Miami-Dade County’s wastewater treatment plants – a capital project valued at $175 million.
