ISTT - International Society for Trenchless Technology

What ISTT - International Society for Trenchless Technology does

The International Society for Trenchless Technology (ISTT) is a UK-incorporated non-profit professional association founded in September 1986, dedicated to advancing the science and practice of trenchless technology for the public benefit. Trenchless technology encompasses methods for installing, rehabilitating, and inspecting underground utilities (water, sewer, gas, electrical, fiber optic) with minimal surface disruption, including horizontal directional drilling (HDD), pipe lining, pipe bursting, microtunneling, and guided boring. ISTT operates as the global umbrella body for 28 affiliated national and regional societies spanning 40+ countries, with 40,000+ newsletter subscribers and ties to thousands of industry professionals (e.g., NASTT's 2,300+ North American members).

ISTT's core offerings are centered on knowledge exchange and community rather than a software product. The flagship asset is the annual International No-Dig Conference and Exhibition (rotating globally, with Auckland 2026 marking the 40th anniversary), supplemented by the monthly Trenchless Works Magazine, free webinars for members, the Trenchless Knowledge Hub housing 3,500+ technical papers, and a 40th Anniversary Commemorative Book. The 2026-launched Trenchless Advantages webpage provides structured content on environmental, operational, and cost benefits. Membership is conferred automatically through affiliated societies and provides access to educational resources, webinars, publications, and the global network.

ISTT's revenue model is a hybrid of membership subscription fees (individual and corporate), event registration/sponsorship/exhibition fees, publication advertising (Trenchless Works Magazine, Commemorative Book with premium tier pricing of US$1,500–US$4,000), and freemium webinar content (free for members, $10 for non-member presentation files). Distribution is primarily through the multilingual website (six languages), the global affiliated society network serving as regional channels, and the annual conference. The organization operates with 11 employees headquartered in Snitterfield, Stratford-upon-Avon, UK, with primary customer segments being trenchless technology professionals, water utilities and municipalities, educational institutions, and contractors/manufacturers/suppliers.

Scale indicators5 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• IWA (International Water Association): Strategic co-development partner of ISTT on water-loss webinars. IWA is a much larger incumbent in the broader water-sector professional association space and overlaps with ISTT on municipal water utility education.
• AWWA (American Water Works Association): The largest North American water-utility professional association. Overlaps with ISTT's water-utility education mandate and reaches many of the same municipal decision-makers, though AWWA covers the full water value chain rather than trenchless specifically.

Direct peers

• UKSTT (United Kingdom Society for Trenchless Technology): The UK affiliate of ISTT, running its own conferences, training courses, and publications on trenchless methods. Highly comparable in mission, member profile, and educational offerings to ISTT.
• ISTT - CSTT (China Society for Trenchless Technology): Chinese national affiliate of ISTT promoting trenchless methods in China through conferences and technical committees. Directly comparable in scope and member base within the China market.
• NASTT (North American Society for Trenchless Technology): The largest ISTT affiliate with 2,300+ members across the US, Canada, and Mexico. Operates its own No-Dig conference series, technical publications, and training programs covering the same trenchless technology domain as ISTT.
• GATT (German Society for Trenchless Technology): German affiliate of ISTT running national conferences, training, and technical committees on trenchless methods. Comparable as a national-level trenchless industry association.
• ASTT (Australasian Society for Trenchless Technology): The Australasian affiliate and host of the upcoming International No-Dig Auckland 2026 conference. Provides the same trade-association functions as ISTT at a regional level.
• JSTT (Japan Society for Trenchless Technology): Japanese affiliate of ISTT promoting trenchless technology research, standards, and education in Japan. Operates with the same trade-association model.

Emerging players

• Water Research Foundation: A subscription-based research collaborative funding water utility research. Competes with ISTT for share-of-voice on water-infrastructure best practices, particularly on pipe rehabilitation topics where ISTT also publishes technical content.
• No-Dig Media / Trenchless Technology Magazine (Benjamin Media): An independent trade publication and conference operator in the trenchless space. Competes with ISTT's Trenchless Works Magazine and No-Dig Conference for industry advertising and event sponsorship dollars.
