GIWA Irrigation tapes


Continuous labyrinth
or flat drippers


Extrusion technology utilizes high-quality specially developed polymers, renowned for their firmness and flexibility. These polymers were developed specially for use in heavy industrial and agricultural environments.

    Using the Gerovit GIWA Irrigation tapes, has advantages of:
  • Maintenance of the drop by drop system takes less time. When plants get deep, consistent watering, they thrive. Inefficient, shallow watering can be a real stress for plants. Drip irrigation system promotes healthy growth and disease resistance plants
  • Drop by drop irrigation, with additional fitting and drippers gives large number of options. The system can be installed at various soil types. It is ideal for irrigation on uneven soil , windy areas as also on usual types of land. Existing sprinkler systems for watering can be adapted to drop by drop system with little effort.
  • Install the drop by drop irrigation system and you will use less water to irrigate. If you are using wells, you will notice a significant decrease in your pumping costs. You will no longer need to water the garden manually. With automatisation of your system, you will not need to hire someone to water the plants while you are on vacation. The reduction of plant diseases and unwanted weeds will considerably reduce your gardening labour and maintenance costs.
Drop by drop irrigation enables efficient watering, supplying crucial part of the plant with water – the root. This way loss of water is prevented, water is not retained on the leaves or soil which significantly reduces evaporation or the outflow of the water.

System drop by drop delivers water to roots of plants and the soil between plants remains dry. This is very important, because if the soil remains dry, most seeds will not germinate.When water is applied using traditional irrigation system, the soil between plants remains wet and most seeds germinate.

Production of Gerovit GIWA Irrigation tapes system and its quality is in accordance with SRPS EN ISO 9261:2011.

Design of continuous labyrinth provides a high degree of resistance to clogging and longer use of the system, and therefore the more rational use of water. A special system of design of a tape with constant labyrinths provides superior performance and uniformity of emitters..
