The German Society for Trenchless Technology was formed in 1990. The Society stages many conferences, seminars and exhibitions either directly or in conjunction with other organisations. International NO DIG 91 Hamburg, NO DIG 95 Dresden, NO DIG Hamburg 2004, NO DIG Berlin 2011 were hosted by GSTT. Much attention has been given to research with the support of the Federal Ministry of Research & Technology, particularly in relation to Sewerage and Utility Tunnels.
