What Is High Pressure Water Jetting?

October 23, 2024

High-pressure water jetting is a method of using powerful streams of water to cut through materials and clean surfaces. It involves forcing water through a small nozzle at very high pressures, often ranging from 10,000 to 25,000 psi. This technique is incredibly versatile, used in various industries for tasks like cleaning pipes, removing debris, and even cutting through solid materials like concrete or metal.

Why Is High Pressure Water Jetting Effective?

High-pressure water jetting is effective because it offers a combination of high power and precision. The speed and force of the water stream can break through tough materials and remove blockages without damaging the underlying surfaces. It’s also adaptable, using either pure water or water mixed with abrasives, depending on the job. Unlike other methods, water jetting does not generate heat or harmful dust, making it safe for delicate surfaces and environmentally friendly.
At Genesis Drainage, we use high-pressure water jetting for a variety of services, from cleaning blocked drains to restoring pipes. This method is not only powerful but also safe and eco-friendly when used correctly. Below, we’ll explore how this technique works, its applications, and why it’s beneficial.

Work Activities That May Use High Pressure Water Jetting

High-pressure water jetting is used in various industries for:

  • Graffiti removal
  • Cleaning building exteriors
  • Drain and sewer cleaning
  • Stone cleaning
  • Surface preparation
  • Hydrodemolition (removing concrete)

Each of these activities requires different water pressures and flows, making water jetting a versatile tool for many jobs.

Protecting the Public

Before water jetting begins, it’s essential to ensure public safety by setting up exclusion zones with cones or tape to prevent accidental injuries from flying debris. If anyone enters the area, the jetting must stop immediately.

Equipment Maintenance

Regular maintenance of the jetting equipment is crucial. Daily checks of hoses, nozzles, and jetting guns help ensure everything is in safe working order. Supervisors should also conduct weekly inspections.

Do’s and Don’ts

  • Do wear all required PPE and use the equipment carefully.
  • Don’t point the jetting gun at anyone or leave the unit unattended.
  • Do take regular breaks to avoid fatigue.
  • Don’t change the nozzle while the system is running.

High Pressure Jet Water Injuries

High-pressure water can cause severe injuries, similar to gunshot wounds. These injuries require immediate medical attention and should be treated as surgical emergencies.

Water Jetting Applications

Examples of Specialist Applications

  • Marine Growth Removal

    Water jetting effectively removes marine growth from ships and offshore structures without damaging protective coatings. It’s a cleaner, safer alternative to abrasive blasting.

  • Concrete Removal (Hydrodemolition)

    Hydrodemolition uses high-pressure water to remove concrete while leaving the underlying rebar intact. This method is faster, quieter, and safer than using jackhammers.

  • Concreteberg Removal

    Concretebergs—hardened concrete blockages in drains—can be cleared with water jetting, saving time and avoiding expensive excavation work.

  • White Line Removal

    Water jetting is now commonly used to remove road markings, providing a cleaner and more environmentally friendly method than grinding or burning.

Is High Pressure Water Jetting Environmentally Friendly?

  • Only Water

    Most water jetting systems use only water, avoiding the need for harmful chemicals in the process.

  • Water Recycling

    Water can be collected and recycled during jetting, reducing water waste and making it a sustainable option, especially in areas with water scarcity.

  • Calder Pump Technology

    Advances in pump technology allow for more efficient and environmentally friendly water jetting systems, with lower emissions and options for green energy integration.
