2010 Large Directional Drilling Rig Census
When horizontal directional drilling (HDD) professionals discuss the size of an HDD rig, they usually refer to the maximum pullback force the unit can develop. The most common industry standard for a large directional drilling unit is defined as having a minimum of 100,000 pounds of pullback force. In addition to pullback, the most common specifications used to categorize HDD equipment are rotary torque of drill stem, rotation speed and the size of drill pipe.

Proper Nozzle Selection In Sewer Cleaning
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.
NASSCO Selects New Executive Director
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.

Rehab Of A 100-Year Old Brick Storm Sewer
The Waterfront Mall Project under construction in Washington, DC, will contain retail stores, restaurants, offices and residential units. Through the middle of the site there is an existing 100-year-old, 90-inch diameter storm sewer about 800 feet long. In what should have been a relatively simple project to rehabilitate the pipe, with a few significant yet manageable challenges, circumstances quickly changed to create the “job from hell.”
CIPP Lining A Cost-Effective Solution For Corroded Concrete Pipes
Utility districts understand that water and sewer pipes deteriorate over time. This is especially true for concrete pipes installed in sanitary sewer systems. An inherent issue with sewage is the build-up of hydrogen sulfide (H2S) gas, which can have far-reaching effects that may not be noticeable until a major problem occurs.
Sanitary Sewer Operations: Blockage Removal
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.”

Know What’s Below – Call Before You Dig
Don't gamble with your safety — if you're a professional excavator or a homeowner, smart digging always requires a call to 811. Knowing where underground utility lines are buried before you dig will help protect you from injury and prevent damages to utilities, service disruptions and potential fines and repair costs.
Pressures in Sewer Cleaning
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.
Editor's Log: Blame And Responsibility
Politics is a tough business. Just ask the U.S. Conference of Mayors.
