A History of Progress

When Robert Spurr Weston began his consulting practice in 1899, he established a tradition of engineering excellence. A pioneer in the field of sanitary engineering, Weston, along with business associate George Sampson, formed the Weston & Sampson partnership in 1916. Together, they were instrumental in developing innovative approaches to the new science of water treatment. The engineering practices fostered by Weston & Sampson continue to this day as the basis of state-of-the-art treatment processes.
