Services

Operational capabilities for municipalities, utilities and industrial sites, supported by specialist equipment from inspection through repair and regulated waste handling.

Sewer and drainage cleaning

We provide high-pressure jetting and suction from small internal pipework to large municipal sewers. We handle long continuous sections without the need for intermediate access. Our equipment removes root ingress, solid obstructions and hardened deposits. We also operate in locations without direct access to manholes.

CCTV inspection, pipe tracing and surveys

Key capabilities:

  • Inspection of all pipe diameters
  • 3D orbital scanning of manhole structures and vertical assets
  • Digital outputs in PDF, DWG, SHP, GIS and DTM formats
  • Laser measurement of slope and deformation
  • Asset-ready data for management systems

We deliver detailed diagnostics of sewer systems with outputs ready for engineering use and long-term asset management.

Vacuum excavation

Key capabilities:

  • Non-destructive exposure of underground utilities
  • Safe excavation in restricted and sensitive environments
  • Removal of sludge, bulk and contaminated materials
  • Industrial cleaning of equipment and structures
  • Material transport to elevated or hard-to-reach areas

This method ensures precise work without the risk of damaging existing infrastructure.

Oil, grease and sludge separation

Key advantage:

  • On-site processing significantly reduces waste volume and disposal costs.

We separate oil, water and sludge efficiently while meeting all regulatory requirements.

Leak testing and technical diagnostics

We carry out pressure and integrity testing and use advanced measurement methods to detect weak points in pipelines and tanks before failure occurs.

Trenchless sewer rehabilitation

We restore pipelines and manholes without excavation. This approach reduces downtime, limits surface disruption and shortens project timelines.

Hazardous waste transport and disposal

We provide ADR-certified transport and full documentation from collection to final processing, including complex and regulated waste streams.
