commitment for creating value

In Swan Water Solutions (SWS) we are aware of the numerous advantages of capillary irrigation systems and the great variety of areas where they can be applied. Therefore research is present in our activity since the very beginning, working to develop know-how in the different systems to improve the existing ones and/or using them in new applications.
Accepting the relative ‘youth’ of capillary irrigation systems and its reduced widespreading, we are convince about the need of developing collaborative experience with their usage, on an international and national basis.

Capillary Physics

Capillary physics principle was defined in 18th Century by James Jurin, but it was in 1907 when Edgar Buckingham formulated the first soil water retention curve. In the seventies of last Century Professors Yechezkel Mualem and Martinus Th. Van Genuchten made the first model to predict hydraulic conductivity in partially saturated porous media, in other words water movement in non-saturated soil.

In the beginning of 21st Century there are technical solutions available, capable of supplying water to cultivated land, with very low energy requirements and meaningful water savings, in comparison with presently used irrigation technologies (sprinkler irrigation and on-surface drip irrigation).

To use those solutions it is essential to know soil/substrate hydraulic properties to make a proper installation design.

SWAN Projects


Jellyfish Barge
(Self-sustaining Floating Greenhouse)

The jellyfish barge project is coordinated by the university of Florence and with Pnat s.r.l.
Swan Water Solutions will collaborate in the commercialization of the jelly fish barge concept and irrigation technology and optimization of substrate and crop yields. Read more


Sustainable Food

Scarcity of proper soil to cultivate and water are the main drawbacks to reach qualitative and quantitative changes in world food demand. The biggest area which can be cultivated is located in some geographical areas, as well as in countries with a high increase in their population rate, like Northern Africa and Arabic Peninsula, land suitable for cultivation is really scarce.Read more


Irrigation of stone fruit trees in Calasparra (Murcia)

Irrigation Project of stone fruit trees in Calasparra, carried out to make a comparison study of drip irrigation and SAVAQ. It started three years ago analyzing, water use, physiological response and fruit quality. Under certain conditions, SAVAQ has got savings up to 50% in the water used, compared with drip irrigation.
