Energy costs in irrigation have increased significantly in the last decade. In Spain, for example, by over 100%. Hydro-powered water pumps, called spiral pumps, are driven by the flow of rivers and canals and offer a sustainable and renewable alternative to electrical pumps. Spiral pumps are simpler, more cost-effective and produce energy reliably 24 hours a day. As a result, spiral pumps represent a viable and attractive option for pumping water, especially in rural areas and in developing countries.
