Weston & Sampson

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.
