Who we are

Watershed Growth Partners, LLC is a New‑York‑based advisory and investment firm focused on water, wastewater, and resource‑recovery—including domestic and hazardous waste.

We help private‑equity sponsors and strategic buyers:

·       Test the deal. We dig into technology, operations, and ESG to confirm (or kill) an opportunity.

·       Find the next bolt‑on. Targeted surveys and direct outreach uncover off‑market acquisitions.

·       Drive the plan. Clear 100‑day and three‑year roadmaps lift margins, sharpen sales, and stay ahead of new rules.

·       Stay on the board—and invest. We put our own capital in, then guide strategy, sales, M&A, and integration quarter after quarter.

With board‑room judgment and hands‑on operating experience, we turn solid environmental businesses into high‑performing platforms that reward both investors and management.
