Opérateur de transport de Wallonie

Opérateur de transport de Wallonie (OTW) (French for: Transport Operator of Wallonia), formerly Société régionale wallonne du transport (SRWT) (French for: Walloon Regional Transport Company), is responsible for the supervision, strategic planning and marketing of a group of five regional public transport directorate branded as TEC or "Transport En Commun" (French for: Public Transport) in Wallonia, Belgium. It is primarily a bus operator, but also operates the Charleroi tram system, and will operate the tramway in Liège once completed. TEC buses and trams are distinctively painted yellow and red.

TEC was founded in 1991 through the breakup of the former Belgian NMVB/SNCV into separate companies for Wallonia and Flanders.

TEC sells the MOBIB smartcard branded "TEC it easy" and runs a chain of shops called Espace TEC.
