Recent capital projects include the Bull Run (Envision Platinum) and Saco (Envision Silver) water treatment programs.
The business model is project-based general contracting and construction management for municipal water utilities, with an expanding industrial water segment following the August 2021 acquisition of Methuen Construction.
