Wind River Environmental
The Firm
Wind River Environmental describes itself as the leading provider of non-hazardous liquid waste services in the eastern United States: septic pumping, grease pumping, installations, inspections, repairs and drain cleaning. It has grown chiefly by acquisition and keeps a page listing the companies it has bought.
What separates it from most firms in this registry is the size of what it buys. These are not platforms or portfolios; they are single family-run pumping companies, often decades old, of exactly the sort a first-time buyer is shortlisting. Each is announced by name on the company's own blog, which makes the pace legible rather than inferred.
For a searcher that is worth knowing in both directions. An owner near retirement in this trade has a standing buyer who does this repeatedly and knows what the business is worth, so a seller may already have a number in mind. It also means a searcher who buys one and runs it well has an obvious eventual buyer.
What It Buys
Marlborough, Massachusetts. Owner-operated septic and grease pumping companies bought one at a time across the eastern states, which is the same business and the same size a searcher in this trade is looking at.
