Ensuring A Successful ‘Burst Day’

14th In A Series From The IPBA

Above ground by-pass of sewer flows or temporary water service lines should be established prior to the installation of the new pipe. The configuration of the temporary piping should not interfere with pipe bursting activities and be able to handle any anticipated peaks in flow that the system may experience. The operation of the temporary system is essential to providing reliable service during construction and in turn keeping the residents and businesses affected by the construction happy (or as happy as they can be during a construction project). Pipe bursting has the ability to install new pipe at a rate much faster than traditional open-cut construction so the duration of temporary lines is often dramatically reduced.

A clear schedule with a defined sequence of events is one of the best ways to manage the expectations of a pipe bursting project and to communicate the steps required to execute a successful installation to all stakeholders. Utility system owners that are well versed in pipe bursting and other trenchless methods often understand clearly what a project will look like whereas utility owners or engineers with little hands-on experience with pipe bursting do not understand all the steps that occur and are critical to the project. Although a daily project schedule should be a part of all construction activities, it is especially essential to burst day.

It is important to make sure everyone involved in a project understands the process and what it looks and feels like. A field crew with experience will protect the area they are working in and actively drive the end product -- which is a new pipe in the ground to serve the public for many years.
