FAQ
What makes tontau different from other irrigation systems?
tontau works completely without electricity and without water pressure - thanks to natural capillary action. In contrast to electronic systems or drip irrigation, tontau works sustainably, requires little maintenance and adapts flexibly to your beds.
How much water can I save with tontau?
With tontau you can reduce water consumption by up to 70%. Thanks to the targeted, needs-based water delivery directly to the roots, not a drop is wasted - ideal for sustainable garden irrigation.
Can I also retrofit tontau into existing beds?
Yes! tontau ONE is perfect for retrofitting as it is inserted vertically into the ground. Installation is quick and easy - without disturbing plants.
How deep do I have to bury tontau?
We recommend a depth of at least 10cm for the tontau TWO. But that depends entirely on how deep your plants are rooted. It is important that your system is well covered with soil so that no water is wasted. With tontau you are flexible: You can lay the system both horizontally (tontau TWO) for long-term projects and vertically (tontau ONE) - depending on how deep you want to irrigate.
Do I need running water or pressure?
No. tontau works without pressure. You can easily connect the system to a rain barrel- just turn on the tap and let the water “stand”
How durable is the tontau irrigation system?
tontau is made of high quality fired clay that is sturdy and durable. The material releases water reliably for years without becoming clogged or wearing out. To ensure you enjoy it for a long time, we recommend a little maintenance once a year. Rinse once and brush off your tonaus.
