How to use water for irrigation? What are the water consumption levels in POWERgrass compared to other types of grass?

Synthetic field with worn fibers

Fully synthetic grass must be watered as soon as the thermometer reaches 22 °C, because the surface accumulates excess heat that causes early player fatigue. At the same time, moist synthetic grass reduces dust, is more enjoyable for play, emits fewer bad rubber odors, and is less abrasive on the player's skin in case of slides.

In case of excessive heat, use the field after 6:00 PM because watering synthetic grass, as is known, lowers the temperature for only 20 minutes and at the same time offers a "sauna effect" during the evaporation phase of the water.

Natural grass, on the other hand, keeps the surface cool, offering a better habitat for athletes and spectators without the need for daily watering. However, during periods of excessive heat (32°C), it must be watered daily but paradoxically, instead of watering more, you need to provide just enough to keep the natural grass alive, that is, maintain no more than 16% moisture in the plant substrate. This way, the lawn can better defend itself from summer heat and regain vitality when the heat passes. In hotter climates, selecting heat-resistant grasses such as some varieties of Poa pratensis or Cynodon dactylon and Paspalum vaginatum offers greater resistance to the summer heat.

Using an automatic irrigation system with 24 sprinklers, the consumption of a watering cycle for natural grass over 7000 sqm is about 24 cubic meters, but evaporation in a field covered by natural grass is much lower compared to bare ground or a synthetic grass field.

On the other hand, synthetic grass also requires irrigation to lower the temperature and make the surface ideal for play. In fact, it is worth noting that the water savings of fully synthetic grass is rather insignificant, if not higher, because, if we were to meet the players' demands, more irrigation is required compared to a natural grass field.

In POWERgrass, the presence of a non-woven geotextile in the artificial backing offers the possibility of retaining more water in the underlying substrate, allowing for less frequent irrigation, which further facilitates the development of deeper root systems resulting in water savings compared to a natural grass field.
