Company
Overview
$135M in Revenue
Annual Revenue
The firm generates substantial annual revenue as a privately held company, now fully employee-owned through an ESOP.
125 Years
Company Milestone
In 2024, the company celebrated its 125th anniversary, marking over a century of innovation in wastewater treatment and environmental services.
Founded in 1899 by Robert Spurr Weston, the firm pioneered U.S. wastewater treatment and grew with George Sampson to become a water-treatment innovator.
From a one-person consultancy in Boston, it expanded across the East Coast into a multi-practice engineering and environmental services firm.
Today it delivers interdisciplinary design, engineering, and environmental services for public and private sectors, tackling projects from parks to water treatment plants.
Typical engagements include large urban park renewals, flood mitigation studies, PFAS removal at treatment facilities, and structural engineering for civic plazas.
Sector strengths include infrastructure systems and water resource projects, supported by environmental permitting, geotechnical, landscape architecture, and construction management.
Unusual facts: it continues to build on century-old innovations in wastewater treatment while evolving into climate resiliency and community revitalization.
