Industrial Wastewater Treatment Systems Engineering Firm, 47-Year Texas Fabricator

Full Editorial Writeup

This is a nearly five-decade-old professional engineering and fabrication firm operating out of Texas that designs, builds, and installs industrial wastewater treatment systems. With over 1,000 systems installed worldwide, the business offers turnkey solutions across the full project lifecycle: feasibility studies, design engineering, in-house fabrication, installation, and startup. The vertical integration is the story here, they control the process from concept to commissioning, which supports quality and margins in a way that pure engineering shops or pure equipment resellers cannot match.

The firm operates from a 4-acre owned site with two production buildings (15,000 and 12,000 sq. ft.) plus a 3,600 sq. ft. office building. It runs lean with 13 employees (9 full-time, 4 part-time) and holds the ability to secure treasury-rated performance bonds for major projects, a meaningful signal of financial credibility that gates them into larger institutional and industrial contracts. Two regional and six to seven national/international competitors define a specialized, high-barrier niche.

The headline economics need scrutiny. The $7.05M ask carries $3.8M of real estate, so on a pure-operations basis the business is roughly $3.25M against $674,810 of cash flow, closer to a 4.8x operating multiple than the 10.45x the headline implies. Regulatory tailwinds around PFAS treatment and zero-liquid-discharge (ZLD) systems give this a genuine growth thesis, but this is a project-based, engineer-dependent business, not a subscription machine, and the retiring owner is central to that expertise.
