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.

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.

The completion of another record breaking pipe installation, this time at Parris Island, a marine training base in Beaufort, SC, marks a series of successful and lengthy crossings of Fusible PVC (FPVC) pipe.

For excavation projects requiring manned entry, shielding and shoring trench walls is a major cost. Material and labor prices escalate as excavations cover more area and become deeper. On many large projects -- especially long runs of large-diameter pipe installation -- slide rail systems have become the preferred method of preventing the collapse of trench walls.

U.S. Environmental Protection Agency Interim Tier 4 emission standards for off-road equipment powered by diesel engines of 175 to less than 750 horsepower will go into effect on Jan. 1, 2011.

Vertical Shores are the quickest, simplest and safest way to shore a trench. Designed for use in more stable soils, they can be placed as fast as you excavate, usually by one person.
