A 1.3 GW combined cycle gas turbine power station needed to reduce operational costs by £100,000 annually without compromising water quality or plant availability. Veolia deployed mobile ultrafiltration and reverse osmosis systems in a 10-year contract, achieving a 90% reduction in regeneration chemistry consumption, >95% demineralisation plant availability, and 800 tonnes annual reduction in chemical discharge to the environment.

How quickly can you deploy a mobile water treatment system?
For emergency situations, we aim to deploy assets within 2 hours of your call.
What is the typical rental period for mobile water service projects?
We offer flexible terms from short-term emergency rentals (days/weeks) to long-term solutions (months/years) based on your needs.
How far in advance should we plan for a medium to long-term use for mobile water services?
We are flexible to your needs. For longer projects, we recommend 3-6 months advance notice for optimal planning and system design, though we can accommodate shorter timelines when needed.
Can rental terms be extended or modified during the project?
Do you provide operators for the mobile systems?
How do costs compare to permanent installations?
Can mobile systems meet the same water quality standards as permanent installations?
Do you handle cross-border logistics and permits?
Can we trial different technologies before committing to permanent systems?
What happens at the end of the rental period?
How do mobile systems support our sustainability and decarbonisation goals?
Modern mobile systems feature energy-efficient designs, and right-sized temporary solutions often have lower overall carbon footprints than oversized permanent installations. We can provide carbon footprint reporting for your sustainability disclosures.
