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.

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.”

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.
