  • Irrigation and drainage device and/or water storage device preferably for water management, in particular watering of (green) areas and/or plants
  • the invention relates to a watering and drainage device and/or water storage device, preferably for watering green areas and/or plants according to patent claim 1.
  • AU 2006 100 165 A4 discloses a method for distributing rainwater for irrigation using an existing urban infrastructure. Such a system is perceived as comparatively inflexible, since on the one hand local irrigation needs are not taken into account and on the other hand the existing infrastructure cannot be adapted to the specific local situation. In this respect, such a system is also considered to be in need of improvement with regard to a precipitation yield.
  • the object of the invention is to provide a watering and drainage device and a watering and drainage method that makes it possible to collect water, for example rainwater, in a simple manner and to keep it available for controlled release in dry periods.

  • at least one water collecting device which is designed to To collect and/or store water, wherein the water collecting device is in direct or indirect fluid
  • An essential point of the invention is to store rainwater for dry periods as well as to buffer heavy rain events and to release the collected water directly to plants and/or green areas depending on the water requirement recorded by sensors and/or based on weather data received from a weather data provider.
  • the evaporation of the water released also leads to a reduction in heat, which is particularly valuable in inner-city areas.
  • the water volume flow can be controlled. This means that when the soil is detected as dry, actuators are controlled or regulated in such a way that correspondingly more water (ie a higher water volume flow) is introduced into the irrigation pipe network.
  • the actuator can be controlled or regulated in this way that less water or no water (i.e. a low water volume flow or a water volume flow equal to 0.0 L/min) is fed into the irrigation pipe network.
  • the water-storing elements of the irrigation and drainage system should be emptied in order to provide buffer storage for the heavy rain.
  • the watering and drainage device should be visible—designed to be perceptible to passers-by—and possibly be able to inform passers-by interactively and/or offer the passers-by the opportunity to actively support the watering in order to possibly awaken environmental awareness in the passers-by.
  • Another important point here is both an information connection - for example via radio - and a fluid connection between the individual (modular) components or water collecting devices and/or buffers and storage reservoirs of the watering and drainage device.

This can include data measured by the sensors in relation to soil moisture of an irrigation zone and/or an amount of precipitation and/or received weather forecast data.
  • physical and/or chemical and/or weather or climate sensors can be used as sensors.
  • temperature, salinity, level, turbidity or a pH value can be determined.

  • the water is no longer suitable for use, e.g. too high a salt content and/or other contamination, or because storage volume is required for an upcoming heavy rain event/flooding, it may be necessary to empty the tanks/storage tanks actively (with a pump) or passively in advance
  • a water volume flow means a water volume per unit of time - for example 0.1 L/min (liters per minute).
  • Direct or indirect fluid connection between the water-collecting device or a precipitation-collecting device and the buffer or buffer tank and/or storage reservoir is to be understood as meaning that further fluid-conducting and/or fluid-processing devices - such as a water purification device - can be connected between a water-collecting device and the buffer and/or storage reservoir (but don't have to).

  • the irrigation and drainage device has a water purification device that is designed to purify water that can be supplied from the at least one water collection device, in particular by sedimentation and/or filtering and/or adsorption and/or absorption, preferably before the water is fed to the buffer and/or the storage reservoir.
  • a (pre-)cleaning of the water makes it possible on the one hand to provide clean water in the irrigation network.
