Sewer hydro jetting, also known as high-pressure water jetting or hydro-excavation, is a specialized technique for clearing obstructions within underground pipes without excavation. It involves directing a powerful stream of water at high velocity through a flexible hose equipped with a special nozzle. This high-pressure water jet cuts through grease, debris, roots, and other blockages, breaking them down into small fragments that can easily pass through the pipe system.
The core components of a sewer hydro jetting operation include:
Water Source: A reliable and substantial water supply is essential to power the high-pressure pump. This can be sourced from municipal water supplies, tanks, or even rivers and lakes.
High-Pressure Pump: The heart of the system, this pump generates immense pressure, typically ranging from 5000 to 40,000 PSI (pounds per square inch), to propel the water through the hose and nozzle.
Flexible Hose with Nozzle: A long, flexible hose delivers the high-pressure water stream to the pipe being cleaned. The nozzle is designed to optimize jetting performance, with various shapes and sizes available for different applications.
Control Unit: This component allows operators to control the flow of water, pressure, and direction of the jet stream, ensuring precise and safe operation.
The concept of hydro jetting has its roots in the early 20th century when inventors sought more efficient methods for cleaning industrial boilers and pipes. However, it wasn’t until the late 1970s that the technology was adapted for use in the sewerage industry.
