CATT is located at the University of Waterloo in Waterloo, Ontario, Canada. Geographically, the Centre is positioned to serve Canada and the northern United States.

The Centre for Advancement of Trenchless Technologies (CATT) was established in 1994 to help municipalities address their buried infrastructure challenges with specific reference to trenchless technologies. Click here for the story of the founding of CATT.

The University of Waterloo, City of Waterloo, National Research Council of Canada and 25 founding members from municipalities, industrial equipment and material suppliers, contractors, consultants, and gas industry provided initial funding and support for the formation of CATT. During the last 10 years, CATT has achieved significant recognition as an international leader in trenchless technology education and research. This success has been due to membership support and participation. Without CATT members, we would not have been able to meet our mandate for trenchless technologies promotion and education through events such as workshops, seminars, courses, training of highly qualified personnel, etc. Since CATT does not receive government funding it relies on industry and member support to meet its mandate. Members of CATT provide financial support through an annual membership fee.

CATT’s mandate is to address infrastructure needs faced by both public sector end-users and industry by providing a common forum for research, education, and technology transfer in the area of trenchless technologies.

CATT is a grouping of university, municipal, industrial, business and government agencies committed to the advancement of knowledge, materials, methods and equipment used in trenchless technologies. CATT’s goal is to serve its members and the public by addressing the critical issues facing underground infrastructure installation, assessment, repair, renewal and management. This is accomplished by providing a forum for:

  • Identification of members’ research needs;
  • Initiation and support of fundamental research;
  • Assistance with the development of new products;
  • Training of highly qualified personnel in the area of underground infrastructure;
  • Creation and delivery of education and technology transfer programs in the area of trenchless technologies and infrastructure management;
  • Support municipalities and utilities in the identification and application of management systems and technologies; institutions and industry.
  • Development of industry protocols, good practice guidelines, as well as material and installation specifications;
  • Networking with national and international researchers and organizations specializing in buried infrastructure and related research.


CATT fulfils its Education and Technology transfer mandate by hosting or co-hosting seminars, technical workshops, short courses and conferences.

These programs are developed to provide industry, municipalities, academics, and students the opportunity to contribute and learn about the advancements in trenchless technology, underground infrastructure initiatives and management. To date programs have been conducted across Canada, the USA, and in Malaysia.

Catt’s seminar and technical committees are responsible for the organization and delivery of seminars and workshops. Seminars are focused on presenting information on specific topics while workshops focus on issues of concerns to CATT members and the trenchless industry and to determine if interest exists to form a research consortium or network.

Technical Committee

In addition CATT’s Technical committee has developed several trenchless technology specifications that have been adopted and published as Ontario Provincial Standard Specifications, for example OPSS 450 Horizontal Directional Drilling.

Research and Professional Services

Research is the foundation of CATT’s presence at the University of Waterloo. Research areas include horizontal directional drilling (HDD), trenchless construction of leachate drains in municipal solid waste, waste water and water pipeline condition assessment, buried infrastructure asset management, testing of pipeline renovation materials, deterioration and renewal of water and waste water networks, etc. CATT also provides professional services such as the testing and development of new products, material testing, and specialized research for CATT members, municipalities and North American trenchless manufacturers and suppliers. A sample of CATT’s diverse client list includes: Sanexen Environmental Services, City of Toronto, City of Waterloo, Evanco Environmental Services, Liquiforce Services, Haley & Aldrich, Channeline, Capital Pipe Services, Plastic Pipe Institute, Royal Pipe Systems, South East Pipe Services, St .Gobain Technical Fabrics, Pressure Pipe Inspection Company, Pipeflo, and UMA-AECOM.
