Catch basins are everywhere — in neighborhoods, along public streets, and lining highways. But most people don’t realize they play a critical role in protecting our environment 🌎 When oil or fuel spills occur, petroleum products like diesel, gasoline, and heating oil can enter these basins — which are connected underground — and eventually flow into ponds, streams, and rivers. That’s where Tri-State Environmental comes in. Our trained crews are certified for confined space entry and equipped with vacuum trucks to safely remove petroleum-impacted sediment, sludge, and pumpable liquids — helping communities stay safe and compliant. If you're a municipality, stormwater engineering firm, property manager, or simply have questions about environmental safety, we're here to help.

A leaking underground storage tank (UST) is not only a hazard to your property’s soil and groundwater, but it can also lead to expensive environmental cleanup costs.
