Blog/ Solutions/ Why is sub-surface drip irrigation revolutionizing landscaping around the world?

In a world where water conservation and sustainability have become crucial aspects of gardening and landscaping, sub-surface drip irrigation is emerging as a revolutionary solution. This technique not only redefines water efficiency, but also introduces an aesthetic and safe approach to maintaining vibrant green spaces. As cities expand and urban green spaces become more valuable, sub-surface drip irrigation is positioning itself as an indispensable ally for landscapers and gardeners. Its unobtrusive and effective application addresses key challenges of modern landscaping, from aesthetic preservation to protection against vandalism, all aligned with global sustainability trends.

Sub-surface drip irrigation special features

Sub-surface drip irrigation (SDI) is an irrigation technique that delivers water and nutrients directly to the root system of plants below the soil surface. This methodology is suitable for a wide range of crops, including both woody and extensive crops. This methodology is fundamental in the development of sustainable landscaping, optimizing the delivery of water and nutrients directly to the roots, and improving the efficiency in the use of water, energy and fertilizer resources.

Benefits of installing sub-surface drip irrigation in gardening and landscaping

SDI offers multiple advantages in gardening and landscaping:

  • Efficient water application: by delivering water directly to the roots, evaporation and surface runoff, crucial in water conservation in gardens, is significantly reduced.
  • More efficient use of fertilizers by applying them directly to plant roots.
  • Weed control: By limiting surface moisture, weed growth is reduced.
  • Reduced water stress and improved fertigation: By delivering water and nutrients more efficiently, overall plant health is improved.
  • Disease prevention: Less moisture on the soil surface reduces the risk of fungal diseases and pests.
  • Energy savings: Less need to pump water to the surface, reducing energy consumption.
  • Wastewater use: Possibility of using treated wastewater, expanding available water sources.
  • Improved soil properties: Underground irrigation can contribute to improved soil structure and quality.
  • Aesthetic integration into the landscape: Because they are hidden underground, subsurface drip irrigation systems are ideal for projects that value aesthetics, a growing trend in urban landscaping.

Sustainable and aesthetic projects thanks to sub-surface irrigation

SDI integrates perfectly into the landscape, maintaining the natural aesthetics of the environment. It is an ideal solution for urban areas and landscaping projects where the preservation of the natural view is paramount. It also contributes to sustainability by reducing water and energy consumption.

Investment in Aesthetics and Safety

Sub-surface drip irrigation represents a strategic investment for projects that value aesthetics and safety. Because the pipes are buried, the risk of damage from vandalism or animals is minimized, while maintaining the visual integrity of the landscape. This feature makes it the ideal choice for public spaces and gardens where visibility of irrigation systems may be a concern.

Sub-surface drip irrigation in lawns: characteristics, maintenance and advantages

solucion01 0013 jardineria04

Sub-surface drip irrigation is particularly beneficial to lawns, providing constant, deep hydration that promotes healthy, vigorous growth. SDI systems for lawns should be designed with lawn type, soil conditions and climate in mind. In terms of maintenance, these systems require less intervention than traditional irrigation systems, although it is important to perform periodic checks to ensure that emitters are not clogged. Advantages include a healthier lawn, reduced weed growth and a significant reduction in water use.

Sub-surface drip irrigation in lawns not only offers all of the above advantages, but also addresses significant drawbacks that have traditionally limited the use of turfgrass lawns in landscaping. For example, in cities such as Madrid, limits have been placed on the coverage of lawns and meadows in green areas to reduce water consumption. However, with efficient sub-surface irrigation systems, these limits could be reconsidered.

Characteristics and Maintenance

El riego por goteo subterráneo en césped reduce significativamente el consumo de agua, incluso en comparación con el riego tradicional con aspersores y difusores. Este sistema permite el uso de aguas regeneradas, eliminando riesgos para la salud pública asociados con la pulverización. Además, al estar enterrado, reduce los costes de mantenimiento y el impacto medioambiental, gracias a la reducción de la necesidad de siega y la utilización de máquinas eléctricas para su mantenimiento.

Sub-surface drip irrigation in lawns significantly reduces water consumption, even compared to traditional irrigation with sprinklers and spray heads. This system allows the use of reclaimed water, eliminating public health risks associated with spraying. In addition, being underground, it reduces maintenance costs and environmental impact by reducing the need for mowing and the use of electric machines for maintenance.

Significant Advantages

Turfgrass lawns irrigated with sub-surface systems can consume less than half the water compared to traditional systems. This was demonstrated in the “Sustainable and Intelligent Turfgrass Meadows” pilot conducted at CENTER (National Center for Irrigation Technology) in San Fernando de Henares (Madrid), where the water consumption of meadows irrigated with a traditional system was compared to those using AZUD’s sub-surface drip irrigation system, RIEGO TURF and IAPSOLUTIONS. The result was a significant reduction in water consumption without affecting turf aesthetics.

Towards a sustainable future

The trial at CENTER is just one example of how sub-surface drip irrigation can transform the use of turf in public and private green spaces. Combining this technology with artificial intelligence promises even greater water savings and efficiency in the future.


In conclusion, sub-surface drip irrigation is much more than an efficient irrigation technique; it is a vital tool for the sustainability of urban landscaping and gardening. It allows the integration of lawns in a sustainable and aesthetic way, contributing to the fight against climate change and the improvement of urban ecosystems. With advanced technologies such as AZUD’s, a world of possibilities opens up for greener and more sustainable landscaping.

Sub-surface drip irrigation is an innovative solution that is transforming the field of gardening and landscaping, offering a sustainable and aesthetically pleasing alternative for irrigation in a variety of settings. With technologies such as AZUD PREMIER PC AS, landscaping projects not only achieve greater efficiency and sustainability, but also benefit from an irrigation system that is virtually invisible, maintaining the natural beauty of the landscape.
