Welcome to the DFI Homepage!

For 25 years, we've been serving the water, wastewater and related industries by providing the best environmental shelters and sound enclosures on the market. Our customers have placed our buildings in every state, and on every continent (except Antarctica... so far!) We are not generally restricted to size, quantity or configuration, and we offer in-house designs and specifications to match the needs of contractors, engineers and their customers. But we remain a small-town business in the way we do things--which means we pass our lack of overhead costs on to you!

(Please be aware that we are a small American company
whose employees only speak English!
Also, we are not a contractor, so although we can schedule shipments to American ports,
we lack the resources to schedule most shipments to foreign ports
or through other countries.)
