Water is essential to every farm, from livestock hydration and crop irrigation to parlour cleaning and effluent management. Our services help farmers across Scotland reduce costs, improve efficiency, and meet sustainability targets. With expertise in trade effluent, wastewater treatment, and water supply upgrades, we offer a complete package of support tailored to the needs of Scotland’s farming industry.
Whether you’re irrigating fields in the Borders or maintaining equipment on the islands, Castle Water delivers reliable supply and expert advice to keep your business running smoothly.
Water quality, efficiency, and sustainability are key challenges for Scottish farmers, but there’s support available through government-backed grant schemes. The Agri-Environment Climate Scheme (AECS) helps fund water management improvements like slurry storage and irrigation systems to protect water quality. The Future Farming Investment Scheme, part of a £46 million capital support package, provides flexible grants to drive efficiency and support climate-friendly farming.
Meanwhile, the Sustainable Agriculture Capital Grant Scheme (SACGS) offers funding for low-emission slurry spreading equipment and covers to reduce ammonia emissions and protect water quality. Farmers can also access free advice and small grants through the Farm Advisory Service (FAS), which helps businesses improve water efficiency and meet environmental targets.
By taking advantage of these schemes, farmers can reduce costs, improve resilience, and strengthen the sustainability of Scottish agriculture.
