This case study explores the innovative measures implemented at Zahradnictví Bílý jednorožec farm in Roblín, located in the Praha-západ district of the Central Bohemian Region. The primary focus is on the installation of a wind-powered water pump to enhance the farm’s water management system. This initiative aimed to provide a sustainable water source for grazing animals, reducing dependency on external water deliveries and improving the overall hydrological conditions of the farm.
The farm, Zahradnictví Bílý jednorožec v Roblíně, is located in Praha-západ, Středočeský kraj, and covers an area of 53 hectares. Established in 2004, this horticultural farm employs three workers who manage the mixed farming activities. The region is characterized by a relatively dry, flat, and mildly warm climate with an average annual precipitation of 530 mm. The soil is predominantly limestone-based, providing specific agricultural challenges and opportunities.
The primary agricultural activity at Zahradnictví Bílý jednorožec v Roblíně is mixed farming. The farm integrates various types of cultivation and livestock management, taking advantage of the diverse landscape. The multifunctional activities include the management of pastures, orchards, and cropland. Additionally, the farm has implemented several innovative measures to improve sustainability, such as installing a wind-powered water pump to provide water for grazing animals. This system includes a wind pump that draws water from an old well, stores it in an above-ground tank, and supplies it to the animals through gravity-fed float waterers. The farm also planted forests and permanent grasslands to enhance
One of the critical challenges faced by the farm is the inadequate hydrological conditions, which historically required transporting water in cisterns, leading to high costs and significant time investment. The installation of the wind-powered water pump was a direct response to this issue, eliminating the need for water transport and reducing fuel consumption. Another challenge is the reliance on wind for water pumping, which can be problematic during extended periods without wind. The farm has addressed this by planning for auxiliary water pumping methods. Additionally, the farm aims to enhance energy independence by planning a future project to install a power plant to supply energy for greenhouses, dryers, and freezers. This underscores the farm’s commitment to sustainable practices despite the challenges posed by the local climate and infrastructure limitations.
The Zahradnictví Bílý jednorožec farm, located in Roblín, was established in 2004. The primary motivation for engaging in Community Supported Agriculture (CSA) was to address the inefficiencies and high costs associated with transporting water for livestock. The farm’s relatively dry and flat region, with an average annual rainfall of 530 mm, highlighted the need for a more sustainable water supply solution. The triggering moment for implementing CSA practices was the realization that using traditional methods for watering livestock was not only costly but also unsustainable in the long term.
The innovation implemented at the farm involved the restoration and deepening of an old well on the pasture, along with the installation of a wind-powered water pump. This pump draws water into an above-ground fiberglass tank, from which it is gravity-fed into float-activated water troughs for the livestock. Additionally, hydrological conditions were improved by planting forests and sowing permanent grasslands. The key innovative element is the use of a wind-powered pump, a method not widely adopted in the Czech Republic, combined with gravity-fed watering systems.
The implementation process began with a thorough assessment of the site, identifying the old well’s location and potential for restoration. A survey was conducted, followed by the excavation of a 4-meter-deep pit using a digger. The well was then lined with concrete rings and covered with a cap. A wind-powered pump was installed, and the well was filled with washed gravel. Two layers of geotextile were applied around the rings, and the top was sealed with compacted clay.
The materials used included a digger, concrete rings and cap, clamps, wind pump, washed gravel, and clay. The total cost, excluding labor, was approximately 70,000 CZK. The project’s success hinged on the technical and informational support from Pavel Floriš, the wind pump supplier, along with the farmer’s extensive experience.
Daily maintenance involves checking the cleanliness and functionality of the water troughs. Basic knowledge of machine operation was necessary for the project’s implementation. The farm now benefits from a sustainable and cost-effective water supply system, reducing the need for transportation and associated expenses.
The implementation of the wind-powered water pump and improved hydrological conditions has led to significant economic and environmental benefits. The farm has reduced its dependency on transported water, leading to lower fuel costs and labor time. The system’s simplicity and minimal maintenance requirements have proven advantageous. Environmentally, the use of renewable energy from the wind pump aligns with sustainable farming practices. The innovative approach has enhanced the farm’s resilience to water scarcity and improved the overall sustainability of its operations.

The decision-makers and leading individuals on the farm, including the farm owner, received technical support and information from the wind pump supplier, Pavel Floriš. The farm owner’s extensive experience and willingness to embrace innovative solutions played a crucial role in the successful implementation. Basic training in machine operation and maintenance was essential for managing the new system effectively.
Looking ahead, the farm aims to further enhance its sustainability by implementing a renewable energy project to power greenhouses, drying facilities, and a freezing box. This project aims to achieve near-total energy independence for the farm. Additionally, the farm plans to advocate for broader changes in agricultural production structures to improve environmental sustainability across the industry.
The key lesson learned from this project is the importance of integrating innovative and sustainable solutions into traditional farming practices. The use of a wind-powered water pump has demonstrated significant economic and environmental benefits. Other farms are encouraged to consider similar renewable energy solutions, particularly in areas with suitable wind conditions and accessible groundwater.
As of today, Zahradnictví Bílý jednorožec in Roblín, established in 2004 and located in the Prague-West district, Středočeský region, continues to operate on a 53-hectare area with three workers. The farm practices mixed farming in a relatively dry, flat, and moderately warm region with an annual average rainfall of 530 mm. Recent improvements include the installation of a wind-powered water pump to supply water directly to grazing animals, enhancing both efficiency and sustainability.
The farm has implemented a wind-powered water pumping system, which is largely self-sustaining and relies on renewable energy. This setup reduces dependence on external water sources and minimizes transportation costs. However, the farm does receive technical and informational support from suppliers like Pavel Floriš. The primary system for water supply operates independently of regular financial support.
The successful implementation of the wind-powered water system is highly dependent on local conditions, such as the presence of wind and underground water sources. The farm’s specific geographic and climatic conditions, characterized by its dry, flat terrain and moderate temperatures, play a crucial role in the functionality of this system. Furthermore, the farm benefits from the owner’s willingness to adopt innovative solutions and his experience, which are critical personal aspects for the success of such measures.
The wind-powered water pumping system is applicable in other regions with similar conditions—specifically, areas with consistent wind and accessible underground water sources. The simplicity and cost-effectiveness of the system make it suitable for small to medium-sized farms looking to reduce their dependence on external water supplies and cut down operational costs. However, regions with little wind or inaccessible groundwater might find this solution less effective. Adaptation to local conditions and the openness of farm owners to innovative practices are essential for successful implementation.
