Trusted in Suction Excavation

The modern way to excavate. The new suction excavator is used by W M Donald on our own projects but is also available for hire – as a self-contained unit complete with operator – to other contractors and developers.


With an ever-growing fleet of suction excavators (no-dig technology), W M Donald work with clients from a range of sectors and on a huge variety of projects, including utility excavations, foundation works, river bed clearance, restoration projects, and clearing blocked gulleys and tunnels, to name but a few.

Think of a suction excavator simply as the civil engineering equivalent of a Dyson or a Hoover – except with a very large collection bin. By minimising the requirement for mechanical excavation equipment, suction excavation virtually eliminates the potential for a utility strike on your site. Not only is suction excavation safer, but it provides a neater, cleaner and smaller excavation.

W M Donald’s suction excavation unit is mounted on a Scania chassis with four axles. By investing in 13.5t axles, W M Donald has increased the suction excavator’s capacity on site by an additional 4 tonnes. This means the W M Donald suction excavator can work for an hour longer on site projects than most other suction excavators before needing to be emptied.

Some specific benefits of using no-dig technology include:

  • Eliminates the risk of utility strikes
  • Large reduction in manual handling, in particular hand-digging
  • Minimises the potential for damage to tree roots
  • Safe, clean and professional excavation site
  • Noise reduction
  • Reinstatement cost savings
  • Simplified plant scheduling and logistics
  • Increased safety for staff and the public

Skills which W M Donald bring to the project

Suction excavation is widely recognised as the best practice for removal of material close to existing underground services as it is safe, efficient, and eliminates the risk of utility strikes or damage. It also reduces labour, exposure to risk, and manual handling.

We have a team dedicated to the provision of suction excavation services, who currently work with local authorities, rail networks, construction companies, civil engineering contractors, utility contractors, British waterways, and health and safety advisors.

In short, the range of uses of the suction excavator is as wide and varied as the imagination and ingenuity of the engineers that specify it on their projects. Our team will work closely with engineers, at all stages of the projects, to ensure that the suction excavation is carried out safely and efficiently.
