Home to one of the oldest volunteer Surface Supplied Diving units in America

Telford Diving & Rescue Unit (TDU) is a non-profit volunteer organization that has been serving the community for over 75 years.

Located in Montgomery County, Pennsylvania, TDU provides services in and around the surrounding counties. We serve the public, assisting municipalities and government agencies wherever there is a need. We also respond to service requests outside the Commonwealth of Pennsylvania. Our missions have taken us as far north as Canada, and we have served across the state lines in Maryland, New Jersey, New York, and Ohio.
