Upgrading a critical RO water system to restore Reliability and efficiency

Background

Cosworth Engines, based in Northampton, is a long‑established and globally recognised engineering company specialising in high‑performance engines for automotive manufacturers and motorsport.

Their facilities include advanced engine test beds and laboratory environments where high‑purity water is essential for material testing and operational processes.

The challenge

Cosworth experienced a total loss of water supply when their ageing RO system failed. The total loss of water meant the client had to buy water in the short term.

Key challenges included:

  • Obsolete components that could no longer be sourced
  • Significant operational disruption
  • Increased costs and labour associated with transporting purchased water
  • Risk to engine testing schedules and laboratory operations

Our approach

Marlowe Environmental Services conducted a full site survey to understand water usage and operational requirements. We conducted a survey, resulting in a proposal of a new system based on that information.

Our approach included:

  • Designing a new RO system tailored to Cosworth’s test bed and laboratory needs
  • Relocating the system to a new preferred area identified with the client
  • Advising on required services and infrastructure for the new location
  • Adding containment measures to protect the site from potential leaks
  • Integrating the new system into the existing pipework for seamless operation

Value delivered 

Marlowe’s upgraded RO system restored full operational capability, providing Cosworth with a reliable, on-demand supply of high-quality water exactly when and where it is needed.

Key outcomes:

  • Reliable, continuous supply of purified water
  • Improved energy efficiency through variable‑speed pumps
  • Reduced wastewater generation
  • Removal of temporary water‑delivery costs and logistical burden
  • Enhanced resilience and future‑proofing of critical testing operations

Client testimonial

“Marlowe Environmental Services provided an excellent solution when our ageing RO system failed. Their team quickly assessed our needs, proposed a modern replacement, and supported us throughout the installation in a new location. The upgraded system has restored reliable, high‑quality water to our test beds and laboratory, while also improving efficiency and reducing waste. We’re extremely pleased with the outcome and the professionalism shown by the Marlowe team.”
