The Walsh Group is the No. 1 Builder of Water and Wastewater Treatment Plants in 2018

CHICAGO – The Walsh Group continues to be the national leader in the construction of water treatment plants, desalination plants and wastewater treatment plants in 2018, according to the latest rankings from Engineering News-Record (ENR) magazine. ENR’s Top 400 Contractors Sourcebook lists The Walsh Group as the United States’ top-ranking contractor in two major environmental categories:

- No. 1 Water Treatment and Desalination Plant Contractor
- No. 1 Wastewater Treatment Plant Contractor

“Water is our lifeline, and communities across the country are in consistent demand of fresh water,” said Roy Epps, senior vice president of water and wastewater of The Walsh Group. “From New York to California, we take tremendous pride in enhancing the treatment plants and delivery systems that millions of homes and businesses depend on.”

The company’s environmental portfolio includes some of North America’s most complex water and wastewater treatment projects, including upgrades to the San José-Santa Clara Regional Wastewater Facility in California, the facilities expansion at the Snapfinger Wastewater Treatment Plant in Georgia, the 70 MGD expansion at Wylie Water Treatment Plant in Texas, facility upgrades at the Middlesex County Utilities Authority Edison Pump Station in New Jersey, and the construction of a new treatment plant at the Temecula Valley Regional Water Reclamation Facility in California.

The Walsh Group has been ranked as the No.1 Water Treatment and Desalination Plant Contractor since 2014, as well as the No. 1 Wastewater Treatment Plant Contractor since 2016.

Engineering News-Record performs annual surveys and ranks companies engaged in general contracting, specialty contracting, engineering, architecture and environmental services, among other specialties. These rankings are based on contracting revenue and are published in the magazine’s 2018 Top 400 Sourcebook.

The Walsh Group is a 120-year-old family-owned company providing design, build, finance, operation and activation services throughout the building, transportation and water markets.
