In order to address the critical issues, respondents to the survey noted that:

  • Rate increases are important.
  • Access to government grants and long-term financing is needed.
  • Public education is considered important.
  • Government regulatory requirements are needed.

The information provided by the Buried Infrastructure Survey is designed for use by municipal infrastructure managers, contractors, consultants, manufacturers and political decision makers, for market analysis and assessment.

This is an annual survey and the 2014 edition has recently been released for input. It includes the completion of a Municipal Buried Infrastructure Survey Report, which outlines key findings, geographical representation of the input received for the survey, a comparison between trenchless technology construction methods vs. other methods, as well as infrastructure material and trenchless method use.

CATT continually strives to bring the trenchless industry and its capabilities to the attention of the public, while supporting and providing benefits to its members. To support this objective, a digital trenchless directory is being developed. This directory will be the first comprehensive source of information for the Canadian trenchless industry.
