The material to be removed is only part of the job. Pipe or surface condition, access, isolation, washwater recovery and the finish required can all change the method.
Deposit and process: what the material is, how it formed and any useful product or sample information.
Pipe or surface: dimensions, construction, condition and any coatings, linings or previous repairs.
Work area: access, isolation and whether the equipment can be taken out of service.
Recovery and finish: how solids and washwater will be collected, and how the finished work will be checked.

Water jetting can remove coatings from steel, but the required surface condition, the steel itself and the route for residues and washwater all need to be defined.
Concrete, mortar and cement washings behave differently in drains. Removal has to clear the obstruction without causing unacceptable damage to the pipe.
Water jetting has specialist applications in casting cleaning. The casting material, the residue to be removed and the required finish determine whether the process is suitable.
Technical notes
Casting: material, dimensions and surfaces that must be protected.
Residue: type, location and how firmly it is attached.
Finish: the dimensional or surface requirement after cleaning.
Chemical process deposits need reliable information about the material before water jetting or washing is chosen. Water cannot be assumed to be compatible with an unidentified process residue.
Water jetting can be used to prepare concrete surfaces. The existing concrete, the material to be removed and the specification for the next operation define the required finish.
Technical notes
Concrete: condition, repairs and any areas that must not be removed.
Preparation objective: contamination or coating removal, or removal of concrete itself.
Finished condition: the surface requirement for the next coating, repair or construction stage.
Hydrodemolition uses high-pressure water to remove concrete. The engineering specification needs to define the area and depth of removal, what must remain and the required condition of the exposed surface.
Technical notes
Removal limits: area, depth and concrete that must remain.
Structure: condition of the concrete and any reinforcement or features that must be protected.
Finished surface: the engineering requirement after removal.
Cleaning water can carry contamination into drains or the wider environment. The job needs a collection method and a drainage or waste route that is permitted for what the water contains.
Drill-pipe cleaning can use specialist water-jetting equipment. Pipe dimensions, previous contents, deposit condition, access and the inspection requirement all affect the method.
Technical notes
Pipe: diameter, length, construction and inspection requirement.
Deposit: previous contents, build-up and any process information available.
Access and recovery: isolation, handling and collection of removed material.
High-pressure water jetting is used to clean deposits from heat-exchanger tubes. Tube size and length, the process deposit, access and isolation all affect the equipment and method.
Technical notes
Tube details: diameter, length and the side of the exchanger being cleaned.
Deposit: what has built up, how it formed and any useful process or sample information.
Access and isolation: how the exchanger can be isolated and reached safely.
Water jetting is used for industrial tote and tank cleaning. For a tote, the previous contents, container construction and intended next use are central to the cleaning decision.
Technical notes
Previous contents: product identity and any relevant safety or contamination information.
Container: material, condition and fittings or linings that must be protected.
Next use and recovery: required cleanliness and how residues and washwater will be collected.
Large-bore pipe cleaning may use specialist water-jetting equipment. Pipe diameter and length, contents, condition, access and the amount of material to recover all affect the job.
Technical notes
Pipe: diameter, length, construction and known condition.
Deposit: material, extent and any process information that helps identify it.
Access and recovery: entry points, isolation and how loosened material will be removed.
Water jetting has specialist deburring and deflashing applications. Part material, the burr or flash and the dimensional or surface requirement determine process suitability.
Technical notes
Part: material, dimensions and features that must not be damaged.
Burr or flash: size, location and production process.
Finished condition: dimensional and surface requirements after removal.
Oil in cleaning runoff changes how the water should be contained and managed. Oil source, likely contamination, drainage layout and the available collection method are the main points to establish.
Water jetting is used to remove paint-booth build-up. The coating, booth surfaces, nearby equipment and the way residues and washwater will be contained all affect the method.
Technical notes
Build-up: coating type, thickness and any available product information.
Surfaces and equipment: materials that must remain undamaged and anything nearby that needs protection.
Containment: how paint residues and washwater will be collected.
Water from coating removal can carry paint, corrosion products and other residues. The coating, containment method and permitted drainage or waste route need to be considered together.
Water jetting is used to remove pavement markings and runway rubber. Pavement type, the material being removed and the finish required afterwards determine whether it suits the area.
Technical notes
Surface: asphalt, concrete or other pavement construction and its condition.
Material to remove: marking, coating or rubber build-up and the area involved.
Finish and recovery: the condition required afterwards and how water and debris will be collected.
Water jetting can be used to strip coatings from pool surfaces. Pool construction, the existing coating and the finish needed for the next treatment define the cleaning objective.
Technical notes
Pool surface: construction material, condition and any repairs.
Coating: type, condition and any available product information.
Required finish: what the next coating or repair specification calls for.
Water jetting is used for reactor and process-vessel cleaning. Previous contents, remaining deposits, vessel construction, isolation and the condition required afterwards all affect the method.
Technical notes
Process history: previous contents and any relevant product or safety information.
Vessel: construction, internals, access and isolation.
Cleaning target: deposits to remove, required finish and recovery arrangements.
Silt mobilised during cleaning still has to be contained and recovered. Its source and possible contamination affect how the water and settled solids should be managed.
Water jetting is used for industrial tank cleaning. Previous contents, tank construction, access, isolation and the condition needed for the next use all affect the cleaning plan.
Technical notes
Tank duty: previous contents and any relevant product or safety information.
Tank construction: material, lining, internals, access and isolation.
Next use and recovery: required condition, residue collection and washwater route.
High-pressure water jetting is used to clean heat-exchanger tube bundles. The side being cleaned, tube dimensions, deposit, access and recovery requirement affect the equipment and method.
Technical notes
Cleaning extent: tube side, shell side or both.
Bundle and deposit: dimensions, condition and what has built up.
Recovery and finish: how removed material and washwater will be collected and how completion will be checked.
