This second edition of Pipe Bursting Good Practices Guidelines parallels the Pipe Bursting Good Practices Course developed by the North American Society for Trenchless Technology and presents the applications, capabilities, and limitations of pipe bursting divided into the following four chapters: Introduction, Background and Definitions, Planning and Design, Construction and Troubleshooting, Avoidance, and Mitigation Measures.
With a worldwide increase in urban growth, more and more municipal governments are facing enormous challenges with aging water and wastewater systems. Potable water distribution piping is often below operational requirements plus, sanitary and storm collection piping is often at peak capacity or even beyond. These utility owners are faced with the onerous task of replacing or rehabilitating their infrastructure while under ever increasing financial and environmental restrictions. The intent of the North American Society for Trenchless Technology (NASTT) publication is to educate owners and their agents of the benefits of a proven alternative technology known as "pipe bursting".
Pipe Bursting is defined as the replacement of the host, or original, pipe by fragmenting the existing conduit and installing the product or new pipe in its place. This construction technique is recognized as the only method of trenchless rehabilitation that can replace an existing line with a completely new pipe, providing a total pipe replacement. Additionally, pipe bursting allows for the replacement of existing pipe with a new line of equal or larger diameter, to maintain or increase flow capabilities.
The First Edition of the Pipe Bursting Good Practices Guidelines was published in 2005 as a supplement to the Pipe Bursting Training Course developed by the North American Society for Trenchless Technology (NASTT). The Second Edition of the Pipe Bursting Good Practices has expanded to reflect the current state of the industry. The Second Edition also has a new section on design calculations and a newly revamped Trouble Shooting section including remediation and preventative measures.
The Second Edition Guidelines were authored by Dr. David Bennett, Dr. Samuel Ariaratnam, and Kate Wallin in conjunction with TT Technologies, Inc., Earth Tool Company, and Albuquerque Underground, Inc.
Topics covered in the book include:
- Pipe Bursting Techniques
- Design Considerations
- Elements of Construction
- Trouble Shooting and Remedial Actions
