Why high-pressure jetting matters

Over time, drainage systems can become restricted by grease, silt, debris, and other materials. If left untreated, this can lead to:

• Blocked drains and overflows
• Slow drainage and system back-ups
• Unpleasant odours
• Increased risk of system failure and costly repairs

Regular or reactive jetting keeps systems clear, improves performance, and reduces the likelihood of disruption.

Our equipment and approach

We use a combination of tanker-mounted and portable high-pressure jetting systems to deliver the most effective solution for each site:

• Tanker-mounted jetters – High power and capacity for large commercial and industrial applications
• Portable jetters – Ideal for confined spaces, domestic properties, and hard-to-access areas

This flexible approach allows us to respond quickly and efficiently, regardless of site constraints or job size.

Applications

High-pressure jetting is suitable for a wide range of drainage and cleaning tasks, including:

• Clearing blocked drains and pipework
• Removing grease, fat, and FOG build-up
• Eliminating silt, sludge, and debris
• Cleaning septic tanks, grease traps, and oil interceptors
• Flushing culverts and surface water systems
• Preparing drainage systems for CCTV surveys or repairs

Our equipment and experience allow us to handle both routine maintenance and more complex cleaning requirements safely and effectively.

Planned maintenance and reactive call-outs

We provide both scheduled and reactive jetting services to suit your needs:

• Routine maintenance programmes to prevent blockages
• One-off deep cleaning
• Emergency response for blocked or overflowing drains
