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.

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.

An estimated 2.7 million television viewers across the country witnessed the climactic finish of the April 25 NASCAR race in Talladega, FL, as driver Kevin Harvick sped past a competitor to capture the lead in the final lap. For Shell, principal sponsor of Harvick’s high-performance car, the event represented a double victory. It reaffirmed the company’s decision to support Harvick and others on the Richard Childress Racing team, aligning Shell products with a winner on the track. And, it provided significant visibility for a critical pipeline safety message.

Choosing the correct nozzle (or nozzles) for a sewer cleaning job can be a daunting task for the uninformed. However, with a little bit of information and understanding of the task at hand, this process can be quite simple. The purpose of this installment of NASSCO’s Tech Tips is to provide the buyer and the end user a quick guide to the initial purchase and field usage of the proper sewer tool.

The National Association of Sewer Service Companies’ (NASSCO) Board of Directors has selected Ted DeBoda, P.E., to succeed Irvin Gemora as executive director. In October 2009, Gemora announced his decision to retire effective February 2011. He purposely made an early announcement because he knew that it would take considerable time and energy to recruit the best candidate.

Brighton, CO, has a successful formula for growth. The community of 30,000 just outside of the Denver metropolitan area has added 750 new businesses since 1990 and is home to a wind turbine and nacelle manufacturing plant that will eventually employ 1,350 people. Part of the formula is a sound infrastructure that provides businesses with access to up-to-date facilities and services.
