What L.D. Docsa Associates does

L.D. Docsa Associates, Inc. is a privately held, family-owned engineering and construction contractor specializing in water and wastewater treatment infrastructure for municipal and industrial clients in North America. Founded in 1958 as Docsa-Smith and incorporated in 1963, the company pivoted to the water and wastewater sector in the late 1990s after winning its first major wastewater project in 1998. Service offerings span consulting and design, metals and process pipe fabrication (via an in-house shop with certified welders), self-performed construction, and ongoing service and maintenance, with delivery through design-build, fixed-price design-build, and Energy Savings Performance Contracts (ESPC) administered through a partnership with NORESCO.

The company self-performs the majority of its construction work — reported at 80% on the Clemens Food Group design-build wastewater pretreatment project — maintaining direct control over schedule, quality, and cost on water, wastewater, biogas, UV, and leachate treatment projects. Core technical competencies include dissolved air flotation (DAF) systems, biogas generation, UV treatment, pretreatment plant construction, and process pipe fabrication. Revenue is project-based, generated through custom contracts with project-specific pricing; no standardized pricing tiers are published.

L.D. Docsa serves a diversified base of municipal governments (City of Kalamazoo, BHSJ Joint WWTP, City of Marshall, City of Dowagiac, Village of Kinross, Rollin Woodstock) and industrial food-processing and rendering customers (JBS USA, Clemens Food Group, Savencia Cheese, Darling Ingredients, Carbon Limestone Landfill), with engineering partners such as Stantec supporting specification work. Sustained annual volume is stated at $25M across 1,000+ completed projects. Operations remain concentrated in Michigan under family leadership (David Docsa, P.E. as Chairman of the Board and Jason Docsa, P.E. as President), with no external institutional investors or public listing identified.
