If you are looking for how cutting-edge trenchless technology is being used in innovative ways, the Sixth Annual Western Regional No-Dig Conference & Exhibition to be held in Tempe, AZ, will present several discussions on that subject.

The Center for Innovative Grouting Materials and Technology (CIGMAT) Research Center was established in 1994 at the University of Houston, Houston TX. CIGMAT’s goals are to foster improved understanding of grouting and coating materials under various applications. Also of interest are other competing and complementary materials and technologies to grouting and coatings used in the construction and rehabilitation of civil infrastructure and offshore pipelines.

Staking University announces the release of its utility locator training video Locating Unlimited. This 113-minute video focuses on two concepts: how locating instruments work and how to operate locating instruments. By covering those two concepts, without dependence on a particular brand of equipment, the video is a timeless resource of information about locating pipes and cables.

For horizontal directional drilling, the first “D” in the acronym HDD is the key to the success of this versatile trenchless technology -- without the directional capability, HDD could never have achieved the impact in utility construction that it has over the last 20-plus years.

Failing sanitary sewer systems are confronting American cities of all sizes. Many systems are operating beyond capacity and old underground infrastructure is crumbling with infiltration causing overflows following heavy rains and leaking sewage contaminating groundwater. Many systems are operating under U.S. Environmental Protection Agency consent decrees in which customers ultimately pay for correcting serious deficiencies.

Europe, like the United States, is struggling to upgrade its infrastructure. In Poland, for example, over 1,000 wastewater treatment plants need to be constructed or upgraded in order to meet European standards which take effect in 2015. Warsaw, the capital and largest city in Poland, has many planned upgrades, including a recent two-year-long project which will provide added capacity and decrease overflows.
