IN Brief:
- Vortex Companies has acquired the business and operating assets of UK contractor Torrent Drainage Services.
- Torrent adds CIPP lining, patch repairs, sewer cleaning, CCTV inspection and robotic lateral reinstatement capability to McAllister.
- The acquisition increases McAllister’s capacity to self-perform trenchless rehabilitation projects across the UK.
Vortex Companies has acquired the business and operating assets of Torrent Drainage Services, expanding its UK trenchless rehabilitation operation as water companies move further into the AMP8 infrastructure investment period.
Torrent’s operations will become part of McAllister, the UK and Ireland environmental and trenchless services business acquired by Vortex in 2025. The transaction adds field capacity across cured-in-place pipe lining, patch repairs, sewer cleaning, CCTV inspection and robotic lateral reinstatement.
No transaction value has been disclosed. Vortex is positioning the deal around operational capacity rather than simply adding another corporate brand, with Torrent staff and resources being integrated into the existing McAllister business.
The two operations already know each other. Torrent teams have previously worked alongside McAllister on rehabilitation projects in the UK, giving Vortex an established base of field experience before the acquisition rather than introducing an entirely unfamiliar contractor into the group.
Mike Vellano, chief executive officer of Vortex Companies, said AMP8 represented “a significant commitment to improving the UK’s water and wastewater infrastructure”, adding that the investment ultimately had to be converted into work delivered in the field.
Torrent’s capabilities cover several stages of a trenchless rehabilitation programme. CCTV inspection is used to establish pipe condition before work begins, while cleaning removes deposits and prepares the host pipe for repair. Cured-in-place pipe, commonly abbreviated to CIPP, installs a resin-based liner within an existing pipe before curing it to form a renewed internal structure.
Patch repairs apply a similar principle to localised defects rather than full pipe lengths. Robotic reinstatement equipment can then reopen lateral connections after lining, allowing service connections to be restored without extensive excavation from the surface.
Combining those activities within the same operating group gives McAllister greater control over the sequence from inspection and preparation through to repair and reinstatement. Individual projects will still depend on network condition, access, customer requirements and the chosen rehabilitation method, but fewer interfaces between separate suppliers can simplify mobilisation and scheduling.
Dan Watson, senior vice president at Vortex International, said integrating Torrent’s resources would improve planning and execution while giving the business greater control over field resources and project schedules.
That field capacity is becoming increasingly relevant as water infrastructure investment expands. AMP8 covers the five-year period from 2025 to 2030 and requires utilities to turn large capital programmes into surveys, design packages, repairs and physical upgrades across existing networks.
Pipeline rehabilitation differs from much conventional construction because large sections of the asset remain buried and operational. Excavating and replacing every defective pipe would introduce substantial cost, disruption and traffic management requirements, particularly in densely developed areas.
Trenchless methods provide an alternative where host pipe condition and geometry permit rehabilitation from existing access points. Their value lies partly in reducing excavation, but the work remains equipment and labour intensive and depends on crews with experience in inspection, liner installation, curing, robotic cutting and quality verification.
That creates a delivery constraint that cannot be solved by capital allocation alone. Additional programmes still require personnel, vehicles, specialist plant and qualified operators before regulatory investment becomes completed work underground.
Vortex has been assembling those capabilities through acquisition. Its purchase of McAllister established a larger operating base in the UK and Ireland, while the addition of Torrent increases the number of services that can be carried out directly within the group.
The wider Vortex portfolio includes pipe, manhole and structural rehabilitation products, liners, mortars, coatings, resins, grouts, UV curing systems, sewer robotics and drain cleaning equipment. The Torrent acquisition strengthens the field delivery side of that portfolio rather than introducing another manufacturing operation.
For clients, the practical change will be an enlarged McAllister operation able to self-perform more trenchless work with its own personnel and equipment. Vortex says the integration is intended to improve coordination from project planning through execution while retaining access to a broader technical base across the group.
The acquisition will be tested against the pace of AMP8 delivery. Water infrastructure programmes may carry substantial approved expenditure, but rehabilitation contractors still have to mobilise enough skilled crews to inspect, clean, repair and reinstate networks within the available programme windows.
Torrent gives Vortex additional capacity at that operational point. The commercial rationale therefore rests less on the value of the transaction, which has not been disclosed, than on whether the enlarged McAllister team can convert growing UK infrastructure programmes into completed rehabilitation work.
