Pipe bursting is a proven method for replacing underground pipelines that provide critical services including municipal water, sewer, gas, storm water, electrical, telecommunications systems and more to people throughout North America and the world.
Pipe bursting is a method of pipe replacement that involves three main forces that must be overcome to accomplish installing a new pipe. A basic understanding of these three forces is required for anyone involved in a pipe bursting project from conception, to design, through final construction. A more detailed level of understanding of the effects of varying ground conditions (geotechnical data) is essential to the success of a project by the senior team members including engineer, owner, contractor and field crews.
The search for the cause of the San Bruno gas pipeline explosion in 2009 that killed eight people has taken a new twist. On June 9, the California Public Utilities Commission issued a report from their hand-picked Independent Review Panel. This was a group the CPUC assembled ostensibly to get to the bottom of the San Bruno explosion.
Some of the most common questions owners and engineers have when considering pipe bursting are “what types of pipes can be burst?” and “what types of pipes can be installed by pipe bursting?” This article will provide insight into answering those questions as well as highlight some of the design and practical considerations that need to be accounted for on any pipe bursting project.
Pipe bursting, like many technologies today, has its own set of lingo or jargon which often times makes it difficult to understand for someone new to the industry or without a lot of direct experience with the technology.
In many American cities, the sanitary sewer laterals that connect homes and commercial structures to sewer main lines have been allowed to deteriorate and become a significant source of sewer system inflow and infiltration (I&I), along with other problems.
The Washington Suburban Sanitary Commission seeks bidders on work including a collection of detailed repair, rehabilitation and replacement tasks within residential areas. This is the first of a series of up to six contracts the commission will publicize via its Central Bidder Registration system. Contractors wishing to submit bids or receive information on future projects should register at the commission's website, Solicitations are available from the project’s website, http://www.wsscwater.com/business/cbr/.
Following tropical storm Fay in 2008, Tallahassee’s 36-inch fiberglass resin force main, originally installed in 1985, failed in three places after 14-inches of rain fell within a 24-hour period. The three breaks occurred within a two-mile section of the force main that runs beneath the Capital Circle Roadway, a Florida Department of Transportation (FDOT) roadway that is one of the most heavily traveled in the city.
