AWWA C622-26 Pipe Bursting of Pressurized Water Pipelines 4 In. (100 mm) to 36 In. (900 mm), 2026
- Foreword
- I.A. Background. Pipe bursting is a trenchless process for replacing an existing pipeline with a new pipeline and is a well-established trenchless method of pipeline replacement that has been in use in the United States for several decades. The process wa
- I.B. History. The AWWA Standards Committee on Pipe Rehabilitation was formed in 1998 to develop standards on the topic. Development of this standard was authorized and initiated in 2009 in response to the water industry’s request for a standard on pipe bu
- I.C. Acceptance. In May 1985, the US Environmental Protection Agency (USEPA) entered into a cooperative agreement with a consortium led by NSF International (NSF) to develop voluntary third-party consensus standards and a certification program for direct
- II. Special Issues.
- II.A. Chlorine and Chloramine Degradation of Elastomers. The selection of materials is critical for water service and distribution piping in locations where there is a possibility that elastomers will be in contact with chlorine or chloramines. Documented
- II.B. Advisory Information on Material Application. Pipe bursting is a dynamic process where a new pipe is installed in the same alignment as the existing pipe without the need for removing the existing pipe, and with minimal trench excavations being requ
- II.C. Constructor Experience. The constructor should have project experience and be trained by the pipe bursting equipment provider(s) in the successful application of pipe bursting. Supervisory personnel should have project experience to ensure that the
- II.D. Distributing Information to Customers. The purchaser shall distribute appropriate information to its customers who will be affected by the rehabilitation work before beginning any fieldwork. Customers may be informed using “door hanger” notices, wat
- II.E. Handling Asbestos Cement (AC) Pipe. The handling of asbestos cement pipeline materials is regulated at the federal, state or provincial, and local levels of government. During the design process, it is important to research the handling guidelines f
- II.F. Pipe Bursting of Asbestos Cement (AC) Pipe. There is no evidence to support that the bursting of buried AC pipe has any negative impacts on the environment or the workers performing the work (refer to AWWA Manual M28, Chapter 13). The steps require
