The city of Kecskemét, like many other municipalities, is facing the challenges of climate change, among which efficient water management is a key issue. Increasingly frequent droughts and heavy rainfall are both causing serious problems, and the city administration is paying increased attention to sustainable solutions. Rain gardens play a key role in this effort, offering not only an innovative solution for managing stormwater but also contributing to the greening of the urban environment.

A Study published in the journal Gradus analyses in detail Kecskemét’s rainwater management strategy, highlighting the importance of rain gardens. The research shows that conventional drainage systems are not always able to deal effectively with sudden, heavy rainfall, which can lead to flooding and overloading of sewage treatment plants. In contrast, rain gardens mimic the natural water cycle and hold water in place, reducing the strain on sewers while helping to recharge groundwater.

The development of rain gardens in Kecskemét serves several purposes. On the one hand stormwater drainage in urban areas to increase efficiency, reducing flood risk and water standing on public land. On the other hand, rain gardens contribute to to mitigate the urban heat island effect, a green surface to soothe the summer heat. It also improves air quality while adding aesthetic value. Rain gardens are a biodiversity can also play an important role in increasing biodiversity, providing habitat for insects and other organisms.

According to the study, in Kecskemét experimental rain gardens have been established in several locations, which come in different sizes and designs. The choice of sites has been made taking into account soil conditions, catchment areas and their integration into the urban landscape. The pilot projects have provided valuable experience on the optimal design of rain gardens, the selection of appropriate plant species and maintenance needs. On the basis of this experience, plans for further rain gardens will be developed, taking into account the specificities of the city.

From design and construction of rain gardens consists of several steps. First, the area is surveyed, drainage directions and soil characteristics are determined. Then the size and shape of the rain garden is designed, taking into account the space available and the expected rainfall. The next step is to select appropriate plant species that are tolerant of changing water conditions and the local climate. Finally, the garden is designed with appropriate soil layers to ensure water infiltration and an ideal environment for plants.

Kecskemét is not only developing rain gardens in public areas, but also in also encourages the population to use them in private gardens. A város információs kampányokkal és tanácsadással segíti a lakókat az esőkertek kialakításában, felhívva a figyelmet a fenntartható vízkazdálkodás fontosságára. Az esőkertekkel nem csak a város vízháztartása javul, hanem a lakosok is egy szebb, zöldebb környezetben élhetnek.

A sustainable water management is not just a passing fashion, but an inevitable necessity in the design of future cities. Kecskemét’s investment in rain gardens is a step towards a more sustainable future that can serve as an example for other municipalities. With rain gardens we not only save water, but also protect our environment for a more livable city. The study points to the need for further research and development in the future to improve the efficiency of urban water management, with rain gardens playing an even greater role.

In the case of Kecskemét, the professional and community work of PCB Project Kft. is a great resource, which you can learn more about on their website.
