Dewatering is a necessary aspect of many underground construction projects. Construction sites near coastlines, rivers, other bodies of water and in other situations may require 24-hour dewatering every day. Heavy rains may fill work areas during storms.

It’s hard to believe that a little more than a decade ago, compact excavators were basically unknown in the United States. Long popular in Europe and Asia because their compact size allowed them to work in small areas of large, congested cities, the first Japanese compact excavators that began appearing on American job sites brought curiosity, even amusement, and their potential was not at first recognized.

For more than 30 years, video inspection has been a fundamental analytical tool for the evaluation and assessment of pipeline integrity. Originally developed as an aid for sewer system maintenance, video inspection equipment has played a key role in the development of a variety of trenchless rehabilitation methods.

This past year (2010) was a busy and eventful period for NASSCO (the National Association of Sewer Service Companies).

There were many highlights, said NASSCO President Brad Dutruch, including:

Rehabilitating sanitary sewer laterals was the subject of a recent series of articles that focused on legal issues regarding ownership of laterals and the emergence of trenchless methods for lateral rehabilitation.

However, another key element in dealing with laterals involves point repairs that effectively address inflow and infiltration (I&I) problems that are structurally sound and do not require rehabilitation.

This year the cured-in-place pipe rehabilitation process and Insituform Technologies, the company that created it, celebrate a significant milestone: Insituform’s 40th birthday and the anniversary of the completion of the first commercial CIPP project, a 12-inch sewer.
