Overview / Context

High pressure drain jetting is a technical procedure employed in the maintenance and restoration of drainage infrastructure. Its primary function is to remove fouling substances—including fats, oils, greases (FOG), soils, and accumulated debris—from within pipe networks. The process is characterised by the application of water at pressures typically measured in multiple bars, effectively dislodging stubborn obstructions that conventional cleaning methods fail to remove.

This technique is widely recognised in the drainage sector due to its efficiency and ability to restore system performance without extensive invasive interventions. It plays a crucial role in maintaining the health of drainage systems, thereby preventing incidents of overflow, backflow, and environmental contamination. The use of high pressure water cleaning has become standard practice for achieving sustained operational efficiency in modern drainage services.

History

Origins and Early Applications

The concept of utilising high pressure water to clear blockages dates back to early manual cleaning techniques employed in primitive drainage systems. Initially, simple water flushing methods were used to encourage flow, though these methods had limited success in removing hardened or accumulated deposits. As industrial demands grew and drainage networks expanded, the need for more effective solutions led to the development of motorised systems capable of generating significantly higher water pressures.

In the mid-20th century, the evolution of hydraulic engineering introduced powered jetting units. These devices were among the first to harness water pressure systematically for cleaning pipes, setting the foundation for the modern high pressure drain jetting techniques that transformed the maintenance practices in the drainage industry.

Industrial Emergence and Technological Advancements

During the post-war industrial boom, advancements in pump technology, materials engineering, and nozzle design spurred the development of high pressure jetting systems. Manufacturers began integrating automated controls and digital monitors into jetters to ensure precise pressure calibration and consistent performance. The introduction of variable nozzle systems allowed operators to tailor the water spray to the specific type of blockage and pipe material, leading to enhanced efficiency and reduced risk of pipe damage.

Technological progress during this period also saw the integration of diagnostic tools such as CCTV cameras, which provided visual evidence of blockages and verified the effectiveness of the cleaning process. This period marked a significant transition from rudimentary water blasting methods to sophisticated, data-driven high pressure cleaning systems.
