Jetting
Jetting is a high-pressure water cleaning service used to remove blockages, deposits, or accumulated residues from relevant systems and infrastructure. It is commonly applied where reduced flow, restricted capacity, or fouling is affecting normal operation.
Overview
Ultra High Pressure (UHP) jetting may also be undertaken where this is specifically required or specified by the client. In these cases, higher pressures are used to address more resilient deposits or build-up, subject to system suitability and agreed controls.
The purpose of jetting is to restore function, flow, or cleanliness within existing systems. The service is not intended to modify, repair, or upgrade assets, and does not involve structural alteration unless separately agreed.
Jetting can be applied across a wide range of systems and environments, depending on access, condition, and client requirements. Scope is confirmed on a site-specific basis, with pressure levels, access methods, and controls agreed in advance.
Impact
Build-up, fouling, or obstruction within systems can gradually reduce performance or, in some cases, cause sudden operational issues.
Restricted flow or impaired containment may also increase environmental or compliance risk, particularly where liquids or residues are not moving or draining as intended.
Jetting provides a controlled method of removing these obstructions, helping to restore system capacity and reduce the likelihood of unplanned disruption. It may be used reactively, where an issue has already occurred, or preventatively to maintain system performance over time.
By addressing blockages and deposits before they escalate, jetting can support operational continuity and help organisations manage risk in a proportionate and planned way, aligned to site conditions and operational priorities.
Confirmation of systems
Initial confirmation of the system to be jetted, the objective of the works, and any access or operational constraints.
Pressure requirements
Agreement of pressure requirements, including the use of UHP jetting where specified by the client.
Site controls
Establishment of appropriate safety, environmental, and site controls prior to starting work.
Jetting
Execution of jetting activities to remove blockages, deposits, or residues from the relevant system.
Waste removal
Management of dislodged or removed material as agreed with the client.
Handover
Functional confirmation at handover, such as restored flow or clearance, where applicable
Compliance & Safety (Conditional)
Where applicable, jetting works are planned and delivered with controls appropriate to high-pressure and UHP activities. This may include task-specific risk assessments, method statements, and exclusion zones.
Confined space frameworks may apply depending on system access and configuration. Permit-to-work systems, isolations, and site-specific controls are followed where required by the client or site operator.
Where waste is removed from site, duty of care obligations apply, and waste handling or disposal is managed in line with agreed arrangements.
The exact compliance and safety requirements depend on the system, location, and scope of work.
Typical Use Environments
Jetting may be used in a range of environments, subject to system suitability and client requirements, including:
• Industrial and commercial sites
• Operational infrastructure environments
This list is indicative only. Applicability depends on the type of system, access conditions, and the agreed scope of works.
Evidence & Reporting
Depending on client requirements and site conditions, evidence and reporting from jetting works may include:
• Job records or work summaries
• Pre- or post-work photographs where feasible
• Confirmation of outcome, such as clearance or restored operation
• Risk assessments and method statements
• Waste documentation where applicable
The format, level of detail, and reporting method are agreed in advance and may vary between sites and projects.

What happens next?
A site-specific assessment is undertaken to confirm access, controls, pressure requirements, and any constraints. The scope of works, including whether UHP jetting is required, is agreed before delivery. Jetting works are carried out under the agreed controls, followed by handover and confirmation of outcome as defined in the scope.
