From refining and blending to transport, forecourt supply, and emergency backup systems, diesel plays a vital role in the UK economy. The sector relies heavily on water, for cooling, cleaning, emissions management, and trade effluent discharge. Castle Water supports diesel operators with tailored services to optimise usage, reduce costs, and ensure environmental compliance.
Whether you manage storage terminals, emergency generators, vehicle fleets, or fuel retail sites, we help you improve water efficiency without compromising safety or regulatory obligations.
Water use in the diesel industry is essential for cooling systems, fuel treatment, equipment washdown, and site safety. Operators must also manage stormwater runoff and prevent hydrocarbon discharge, with sealed drainage and spill containment required by law.
Castle Water supports diesel businesses across the full fuel lifecycle, from blending and storage to distribution, retail forecourts, and backup power systems, helping ensure efficient, compliant water and wastewater management.
Diesel businesses operate under strict environmental regulations that govern how water is abstracted, used, and discharged. Effluent disposal is regulated under the Environmental Permitting Regulations in England and Wales, requiring many sites to install pollution control systems such as Class 1 interceptors to prevent hydrocarbons from entering surface waters. In areas designated as groundwater protection zones, further restrictions apply to what can be discharged or stored on site. Operators must also implement robust spill containment measures and maintain up-to-date emergency response plans to address accidental releases.
Castle Water helps diesel operators navigate these regulatory requirements with confidence. Our expert support ensures that your water systems remain fully compliant, environmentally sound, and aligned with best practice, helping reduce operational risk and protect local watercourses.
Diesel operations, from bulk storage and blending to haulage depots and backup power generation, demand robust wastewater solutions and strict pollution prevention.
