TST was founded in Oregon in 1969 as a utility drafting services company. We later engaged in field inventories and utility management software. In the 1990’s we collaborated with several utilities and started the legacy of the software we sell today. The Plantworks and Mapworks products preserve that legacy and expand on it, and are the first generation actively presented to a national audience. TST software enables Electric, Water, Storm, Sanitary, and Gas distribution utilities. Give us a call. Maybe we can help.
