Irrigation & Landscaping
First: Greenhouses
The current and future Saudi vision in the agricultural sector focuses on relying on agricultural greenhouses as one of the most important solutions to address water scarcity and the excessive depletion of water resources in traditional agriculture. This approach falls within the Kingdom’s efforts to achieve sustainable agricultural development, supporting national strategies and encouraging and facilitating the provision of agricultural loans to farmers for implementing greenhouse projects through the Agricultural Development Fund.
For this reason, we have taken part in the Kingdom’s agricultural development journey. Our organization has been managing greenhouse projects and their warehouses for more than ten years, supported by the launch of our greenhouse manufacturing plant, which designs and manufactures greenhouse steel structures using the latest programmed cutting and welding technologies, operated by qualified engineers and trained technical labor. In addition, we have partnered with several national and international companies to provide greenhouse requirements such as cooling, ventilation, lighting systems, and more. This has enabled us to deliver comprehensive solutions to our clients and meet their needs at competitive prices and high quality.
Types of Agricultural Greenhouses
Traditional Greenhouses (Seasonal Cultivation Only)
Cooled Greenhouses (Year-Round Cultivation)
Multi-Span Agricultural Halls (Year-Round Cultivation)
Multi-Unit Agricultural Halls (Year-Round Cultivation)
Agricultural Halls with Drip Irrigation System (Year-Round Cultivation)
Greenhouses
Greenhouses are a modern agricultural method used for cultivating crops such as vegetables, flowers, medicinal plants, and ornamental plants. They are used for protected agriculture, where the internal climate can be controlled using cooling and heating systems to regulate suitable temperature and humidity levels for plant germination, as well as to protect plants from wind, sandstorms, and rain.
Advantages of Greenhouse Construction
- Producing vegetable crop seedlings outside their normal growing seasons throughout the year.
- Increasing productivity compared to traditional farming by increasing plant density and producing crops with high market-quality specifications.
- Reducing water consumption through efficient irrigation systems and better irrigation management.
- Controlling suitable temperature levels for plants and protecting them from extreme heat and frost through heating and cooling systems, as well as better pest control compared to open-field agriculture.
- Producing a wide variety of flowers and indoor plants throughout the year.
- Reducing labor requirements for cultivation and production processes.

Greenhouse Equipment - Evaporative Cooling Systems
Evaporative cooling systems are used in greenhouses to reduce internal temperatures and improve air quality. These systems include exhaust fans, cooling pads, and water distribution networks, helping to create an optimal environment for plants.
Exhaust Fans
Cooling pads are made of specially treated cellulose sheets assembled in a structure that allows air to pass through them. When the system operates, hot air flows through the water-saturated pads, where it is cooled and humidified before entering the greenhouse.
Cooling Aluminum Profiles
Cooled aluminum sections are used to support and install cooling systems. They are lightweight, durable, and easy to install, helping secure cooling pads and ensure efficient air distribution inside the greenhouse.
Cooling Washers & Systems
Evaporative cooling washers and systems are designed to operate with greenhouse cooling setups. They pump water to the cooling pads, include filtration systems for protection, and are equipped with electrical control panels to ensure safe and reliable operation.

Second: Landscaping Department of Garden, Park, and Irrigation Network Design & Implementation Works
The Landscape Design, Parks Implementation, and Irrigation Networks Department is considered one of the most important departments of Al Anhar Al Arabia Company for Irrigation and Agriculture Systems, as it represents the starting point of our agricultural activity. We have successfully completed many major government projects and are accredited as irrigation and agriculture contractors with several ministries and both public and private entities across the Kingdom.
This department marked the beginning of our agricultural operations, through which we executed numerous significant government projects. As a result, we have gained extensive experience and built strong trust with our clients and success partners from both governmental and private sectors throughout various regions of the Kingdom.
Irrigation and Landscape Works
The presence of parks and recreational areas is considered one of the essential elements in modern city designs and urban planning, and in people’s lives, due to their multiple benefits, including aesthetic, economic, cultural, health, and recreational value.
Public parks and recreational areas are also considered permanent destinations for city residents to spend leisure and relaxation time. They often include designated areas for practicing sports activities such as walking or jogging, children’s playgrounds, seating and rest areas, and various recreational facilities.
The company has also specialized in executing landscape and irrigation network projects for greenhouses, as well as planting trees and palm trees, using the highest quality locally manufactured and imported products.
Drip Irrigation
Drip irrigation is a system in which water is applied directly to the soil in quantities close to field capacity, in the form of small droplets delivered directly to the root zone. This system is distinguished by wetting only part of the soil, while other areas remain dry throughout the season. As a result, it provides many benefits with very few drawbacks.
Advantages of Drip Irrigation:
Promotes plant growth, increases crop yield, and reduces soil salinity problems in the root zone.
Improves and reduces the use of fertilizers and other chemicals, lowers labor requirements, and enhances agricultural operations.
Reduces weed growth and allows maintenance operations to be carried out during irrigation.
Allows the use of relatively saline water and can be combined with sprinkler or flood irrigation systems.
Enables the system to operate fully automatically.
Consumes approximately half the amount of water required for sprinkler irrigation.
Reduces fungal diseases since plant leaves are not wetted, making it highly suitable for desert lands.
Can be used in uneven areas with natural topography unsuitable for surface irrigation.
Reduces water loss caused by deep percolation below the root zone.
Artificial Grass
There is no doubt that modern technology in the field of petrochemical industries has contributed significantly to providing alternative solutions and materials for the agricultural sector. One of the most important of these alternatives is Artificial Grass.
Artificial grass is manufactured according to international standards to serve as an effective alternative to natural grass, maintaining its appearance and texture while avoiding the common problems and disadvantages of natural grass. Artificial grass is made of polyethylene fibers designed to closely resemble natural grass in both form and feel. In addition, it includes a mixture of silica sand and rubber granules, which enhances durability and provides a natural, realistic surface.
Given the scarcity of water resources in the Arab region, artificial grass has become an ideal solution for water conservation and maintaining green spaces. It is widely used in gardens, children’s playgrounds, chalets, sports fields, and recreational areas.
