Of all sanitary sewer operations, blockage removal is perhaps the most demanding and highly visible. For the purpose of this discussion a blockage is defined as the “stopping or interruption of sanitary sewerage flow.”

NASSCO member Barry Howell, General Manager, Visu-Sewer, Inc.

Without a doubt, the most misunderstood facet of sewer cleaning is the relationship between flows and pressures. Generally, pressure is mistakenly viewed as the wildcard or the reason for concern, and flow is usually ignored. Operators often misunderstand the operation of their pump, the relationship to hose diameter and length to performance and other variables of jetting.

Cured-in-place pipe rehabilitation technology for sewer systems has been an industry force for decades. The technology is generally well-accepted as an excellent trenchless alternative to dig-and-replace.

The past year has been another busy one for NASSCO – the National Association of Sewer Service Companies – as the association continues to make significant contributions to the storm and sanitary sewer rehabilitation industries.

Irvin Gemora, NASSCO Executive Director

As executive director of the industry's leading trade association, I've been honored to learn and grow in this important role during the past eight years. Our industry is still considered young and watching it grow has been exciting. As I look back, I think about all that has changed since I was a young sewer rat, literally getting down and dirty to learn on the job.

For the first time in its nine-year history, demonstrations will be part of the RehabZone at the 2010 UCT Underground Construction Technology International Conference & Exhibition, better known simply as UCT.

Over the past 20 years, pipebursting has become firmly established as a primary method of replacing underground pipe infrastructure past its useful life.

The RehabZone will be hosting live product and technology demonstrations at the Underground Construction Technology International Conference & Exhibition (UCT) in Tampa, FL, on Jan. 19-21, 2010.

In a relatively short period of time, NASSCO's Inspector Training and Certification Program (ITCP) is establishing new industry standards for inspecting cured in place pipe (CIPP) installations.
