In the literature and in the relevant regulations, a constructed wetland is also referred to as a plant bed, reed bed or reed bed sewage treatment plant. Technical terms such as planted soil filter or planted filter are also common. The plants consist of a permeable filter substrate and are planted with moisture-loving plants. A distinction is made between plants with a vertical or horizontal flow vector. Operators of a constructed wetland do not pay connection fees or wastewater contributions. However, they are obliged to regularly prove the function of the plant to the water authorities. For this purpose, they must submit a maintenance contract with a suitable company.

Local politicians and committed citizens have to struggle their way through this decision-making process. We, as natural pool planners, are happy to contribute to this process with our designs and cost estimates.

Against the backdrop of increasingly frequent and intense heavy rainfall events as a result of climate change, both private properties and urban infrastructure systems are facing a new challenge. We develop nature-oriented solutions for dealing with rainwater as a basic building block of water-conscious urban development. Coordinated blue-green-gray infrastructures strengthen the local water balance and provide important ecosystem services. Functionality and experienceability are equally important to us as the closing of material cycles and the holistic character in dealing with water as a resource.

Green roofs have proven to be ecological and robust solutions in recent decades and are on the rise in many regions worldwide. The same applies to constructed wetlands for near-natural wastewater treatment, which are attracting considerable international attention and application. The combination of both systems opens up the possibility of combining wastewater treatment with building air conditioning, thus creating further potential uses.
