Where is dry tapping most commonly found?

Dry tapping is most commonly found during the installation of a main and/or services because this process involves making connections to existing pipelines without disrupting the flow of water. Specifically, dry tapping refers to the method where a hole is drilled using a specialized tool to create an outlet from a pipeline while keeping the pipeline pressurized. This allows the installation of new services without the need to shut down the water supply, which is essential for maintaining service to customers.

In the context of pipeline installation, dry taps enable utility workers to connect new service lines or main extensions efficiently. This technique is critical in maintaining the integrity and continuous operation of the water distribution system, especially in urban areas where interruptions can lead to significant inconvenience.

The other scenarios listed, such as pipeline cleaning, meter installations, and trenchless technology applications, are typically associated with different procedures and objectives that do not primarily involve the technique of dry tapping as a standard practice.
