The UK petroleum refining industry plays a vital role in national infrastructure, supplying over 60 million metric tonnes of refined fuel annually. With just six major refineries operating across key estuary locations, water use and sustainability in petroleum refining are under increasing scrutiny.
Castle Water supports petroleum businesses with tailored commercial water solutions, helping them manage supply, wastewater, and trade effluent safely and cost-effectively. Whether you manage a refinery, distribution depot, or forecourt network, our services are designed to help you stay compliant, minimise environmental risk, and optimise performance.
Water is vital for every stage of crop production, from seedbed preparation and irrigation to spraying, washing, and runoff management. With increasing pressures on cost and environmental responsibility, making your water use more efficient is essential for sustainable, productive farming.
Petroleum businesses rely on water across the refining and distribution chain:
Hydraulic systems and cooling
Fire suppression and foam systems
Tank and vessel cleaning
Forecourt washdown
Bunded surface water management
Each of these applications generates effluent or wastewater that must be handled under strict legal frameworks, including the Environmental Permitting Regulations and local water company byelaws.
Specialist support designed to help petroleum refineries stay compliant, efficient, and resilient in a heavily regulated and resource-intensive sector.
From managing complex wastewater discharge to reducing operational water use and meeting strict environmental standards, petroleum refineries face unique challenges. Our team of industry specialists works closely with you to navigate the regulatory landscape, implement cost-effective water solutions, and future-proof your operations against evolving compliance demands and sustainability expectations.
Petrol refining, blending, and retail operations come with complex water management requirements, from cooling and washdown to effluent discharge and pollution control. Businesses across the fuel supply chain choose Castle Water to provide expert support with regulatory compliance, site infrastructure, and wastewater services tailored to high-risk environments.
With increasing environmental scrutiny and the need for accurate monitoring, the petrol industry faces challenges around water abstraction, stormwater runoff, and discharge control, particularly at depots, forecourts, and blending sites. Castle Water helps petrol operators stay compliant, reduce environmental impact, and streamline operations through data-driven water management.
