An optimal water flow for your crop with the correct fertilizer and nutrient dosing: we understand you completely. We have extensive knowledge of irrigation, water disinfection and nutrient dosing and ensure you that you can manage your irrigation process in the most optimal way.  

The best water for your crop

Water is essential for growing your crop. But as you know, finding the correct dosing of nutrients, fertilizer and water flow can be difficult. And with stricter legislation and environmental policies, secure use of water and reducing & recycling waste water is becoming more important every day.



Efficiently manage your water flow

The key to these challenges is smart (re)use of water. Priva offers innovative solutions for your entire irrigation process. We’ll help you from start to end: from disinfecting water and removing bicarbonate, to mixing and dosing water with the right concentration of nutrients at the right time and from measuring the drain water to recycling it.

Product marketeer Kees van der Kruk about water:

“In an environment where healthy growth, of your crop and your company, takes center stage, it is important that the various water flows are optimally controlled, and that the correct quantities of fertilizers are administered at the same time. The systems we develop allow you to efficiently dose high-quality irrigation water and to recirculate it safely.”

Kees van der Kruk | Priva

The smart water cycle

After your water intake, which can come from various sources like tap or rain water, the water is treated with an UV-disinfection to ensure safe entry water. This also adds the possibility to recycle drain water. The next step is Bicarbonate removal; it provides the right Ph-level for nutrient uptake. The fertilizer dosing systems add the nutrients at the right dosage with expert precision.

Our advanced irrigation monitoring system makes sure the correct dosing reaches your crop. The sensors measure evaporation and drain levels. Furthermore, the plant itself can determine the time at which watering takes place.

The drain water is then UV-disinfected again. This ensures that the drain water can be recycled and up to 99% of the crop protection agents are broken down before discharge.
