The Southern African Society for Trenchless Technology (SASTT) was established in 1992 in Pretoria, South Africa, with the mission to promote the use of trenchless technology (TT) as a sustainable and efficient approach to underground infrastructure development and maintenance. This innovative technology minimizes surface disruption and environmental impact while providing cost-effective solutions for the installation and rehabilitation of underground services. SASTT operates as an ethical, neutral platform to advance the adoption of TT by offering technical resources, training, advocacy, and support for professionals, asset owners, and municipalities. The society also aligns itself with global developments through its affiliation with the International Society for Trenchless Technology (ISTT), reflecting its commitment to global best practices and innovation.

In 2011, SASTT demonstrated its leadership in the field by hosting a master class on trenchless technology in collaboration with No-Dig South Africa. A second similar No-Dig South Africa and Masterclass was held in 2014. This was followed by hosting the prestigious international No-Dig Conference in Cape Town in 2018, cementing SASTT's position as the regional hub for trenchless innovation. The Society draws its members from diverse sectors, including municipalities, consultants, contractors, and suppliers, fostering a collaborative environment. As the gateway to Africa, SASTT is committed to expanding the adoption of trenchless technology across Southern Africa, driving sustainable infrastructure solutions throughout the region.
