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.

Fort Worth sewers get overhaul

Sewer lines will soon be getting a major overhaul in the city of Fort Worth, TX. The city council approved a $446,192 engineering contract with White Rock Consultants to begin work on the new improvement project.

Survey focuses on US cities’ water/wastewater rates

Black & Veatch has released the results of its sixth 50 Largest Cities Water and Wastewater Rate Survey, a resource for water and wastewater utilities. The survey highlights customer charges for water and sewer service for residential, industrial and commercial customers.

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.

Dewatering equipment from Rain for Rent, Thompson Pump & Mfg., Godwin Pumps, Grindex Pumps, Gorman-Rupp Pumps, Goulds Pumps/ITT, Multiquip, ITT Flygt Water & Wastewater, Allegro Industries and Griffin Pump & Equipment.

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. After years of largely underfunding and ignoring the festering problem under their streets, this group authorized a “special report” stating the obvious: they’ve got serious problems with their sewer/water systems, including the underground piping infrastructure.

Changing The Communication Landscape Through Construction

It has been said that good news travels fast. In a town like Lansing, MI, news travels slightly faster. The tight-knit capital community is, without a doubt, one of Michigan’s biggest small towns. So when construction hits, the word gets around.
