How to ensure the sustainability of adaptation?

Smart technologies for stormwater management along roads and highways

The environmental monitoring of roads and highways is crucial for guaranteeing safety, sustainability, and effective infrastructure operation. The deployment of sensors and cutting-edge technologies facilitates the identification of contaminants and parameter fluctuations in incoming flow, improving maintenance strategies. The incorporation of IoT and automated control systems enables real-time oversight, strengthening the adaptability of hydraulic networks and supporting environmental preservation. This abstract emphasizes how these innovative technologies can foster the advancement of novel and efficient solutions to these challenges. This leads to significant improvements in stormwater management and the removal of pollutants such as microplastics, heavy metals, and others, as well as enabling the remote monitoring of treatment facilities along highways. Case studies are here discussed, focusing on the remote and automated management of stormwater treatment systems, combined with advancements in monitoring sensor technology applied to sections of Italian highways to estimate plant efficiency in treating stormwater runoff. These case studies clearly illustrate the advantages of a comprehensive knowledge-based approach to stormwater management, relying on ongoing and real-time surveillance of hydraulic infrastructure, and how these technologies can create a broader framework for environmental monitoring.

Real-time Monitoring of Total Suspended Solids in Stormwater

A rainfall database containing radar data since 2001

Weather radar data are an excellent means to provide precipitation information, in particular with a detailed spatial information. Data have been measured for several decades now, but access to the data is tedious because of the large data amounts, with a resolution of typically 1 km x 1 km every 5 minutes. Therefore, a data base has been created which allows access to the data for any area and any site. Main highlights are however the possibility to retrieve past events for each location and individual duration intervals, providing also information which can be further analysed statistically. This approach has been implemented for the totality of the German RADKLIM data set of the German Weather service, covering all of Germany and starting 2001. The implementation is a web based system which is available for open access since May 2024.

The quality of stormwater in the context of drinking water protection

Long-term studies on the quality of stormwater runoff from various urban catchments indicate the presence of priority substances contaminating these waters, found either in dissolved form or bound to suspended solids. The recipients are most often SWB (surface water bodies) or soil, where the introduced pollutants accumulate and subsequently infiltrate into groundwater. Current legal regulations do not enforce the use of appropriately selected high-efficiency pre-treatment devices that would reduce pollutant loads, which consequently fails to provide sufficient protection for the recipients.

Characteristics of Surface Runoff in Urban Catchments: Modern Research Procedures Mimicking Real-World Conditions

Michał Wiśniewski, an expert at ACO and Product Manager in building drainage systems and separators, will focus on another important issue – the formation of surface runoff in urban areas. Michał will discuss how effective pollution separation systems and solutions dedicated to water management can contribute to improving the quality of stormwater in cities and support efforts towards sustainable stormwater management. His presentation will provide practical insights on how to combine advanced environmental engineering with ecological responsibility.

From detention to true retention

We invite you to attend the talk "From Detention to Retention", which addresses one of the key topics in the context of climate change—stormwater management in an era of dynamic and unpredictable weather events. 🌧️ The presentation highlights how climate change impacts urban infrastructure and natural ecosystems. We will discuss the differences between detention and retention, their applications in water resource management, and how traditional sewer networks—designed based on historical patterns—are no longer sufficient to meet modern challenges. We will also explore how automated systems supported by artificial intelligence will help address these issues in the future. Key challenges will be discussed, such as the lack of accurate forecasting models for climate change impacts on precipitation and the growing need for more efficient stormwater utilization. We will also present innovative solutions that enhance the management of existing systems without requiring costly infrastructure overhauls. During the talk, you will discover cutting-edge technologies and automation solutions that help protect cities from flash floods and reduce flood risks. Additionally, we will showcase inspiring examples of rainwater reuse for both practical and ecological purposes. This talk is perfect for those interested in the future of cities, environmental engineering, and practical climate adaptation strategies. See you there!

Adaptation in the context of infrastructure – from standard solutions to non-standard applications: the role of humans as a key tool

Adaptation: Challenge, Technology, Human Adaptation, according to the definition in the Polish Language Dictionary, is the process of adjusting to specific conditions. In the context of climate change, it is most often considered through the lens of temperature, precipitation, and overall climate trends. However, effective adaptation requires a broader perspective—one that takes into account existing conditions such as infrastructure, buildings, terrain, and spatial constraints. As part of the session dedicated to tools and technologies supporting adaptation, an important question arises: can human experience and knowledge be considered one of these tools? The answer is yes. Although stormwater management technologies have not undergone fundamental changes in the past decade, the way they are applied has evolved. Today, standard solutions are used in non-standard ways, tailored to unique project conditions. During the presentation, we will showcase specific examples based on completed and operational investments: Linear drainage feeding a rain garden in Szczecin. Drainage integrated with an infiltration system in Niechorze. Soakaway crates as a method to increase the capacity of an open reservoir in Inowłódz. Hybrid underground retention tank in Krzeszyce. A method for additional retention at the Old Market Square in Poznań. Adapting to existing conditions is a more complex challenge than building from scratch, requiring customized, reliable, and high-quality technologies. However, the most crucial tool for effective adaptation remains the human factor—knowledge, experience, and the ability to find unconventional solutions.

Automatic Water Quality Monitoring – From Data to Action

The presentation will demonstrate how automatic and continuous measurements of physicochemical parameters enable the detection of pollutants in stormwater and beyond. Interesting case studies and the possibilities of utilizing constant online access to measurement results for quality control will be discussed based on real data and charts. Specific examples of modern monitoring applications in stormwater management will also be presented, along with innovative projects supporting water protection and reuse.

Coffee break

Blue-green infrastructure in the revitalization of inner-city areas

Why is it so important to include the creation of blue-green infrastructure, increasing rainfall retention, and increasing the share of biologically active surfaces in revitalization projects? What exactly do these issues, described in the Water Deficit Prevention Program, involve? Why are elements of blue-green infrastructure so important in the context of retention? The development of blue-green infrastructure plays a significant role in increasing retention in urban areas. By introducing blue-green infrastructure, the potential of plants to retain water is utilized, which contributes to increasing the resilience of urbanized areas during drought periods. The combination of ecology with utility functions that protect against flooding and flash floods works excellently in the revitalization of densely built urban spaces. The oval-shaped layout of Kościelna Street with the characteristic square known as Nawsiem is a remnant of the oldest center of Jeżyce. Nawsiem was the common property of the residents – it was the place where their daily lives took place. This space was used as a market square, pasture, and also as a social center. In Jeżyce, part of Nawsiem was occupied by two ponds fed by the nearby Seganka River, near which there was a water mill. Once Seganka stopped being used as a source of drinking and domestic water, it began to disappear from the surface of the earth. Like most watercourses in the city, it was almost completely canalized in the second half of the 20th century. The main assumption of the project is the revaluation of the Nawsiem area of the former Jeżyce village, which involves organizing a green area with accompanying functions, including a hybrid rainwater management system. The project will use developed and lush low and high greenery with high landscape value, creating a natural habitat for animals and a hilly terrain that separates the green area from the roadway. The hybrid rainwater management system was designed based on a main underground retention tank with a large capacity and surface solutions for filtration and retention of rainwater. The system will be completed with an infiltration basin and an underground retention tank collecting purified rainwater for irrigation of greenery.

Community participation in the development and maintenance of green-blue infrastructure: Is it worth it?

Engaging residents in shaping green-blue infrastructure brings numerous benefits—it creates more functional and attractive public spaces, strengthens the sense of community and responsibility, and raises environmental awareness. However, this process is not without challenges. Conflicting interests, prolonged investment timelines, and a lack of competencies among participants can pose obstacles. I will discuss how to overcome these challenges and highlight the crucial role of communication and education throughout the process.

Financing adaptation as an element of ESG policy

Climate change is increasingly driving the need for adaptation. Large and well-managed cities, aware of its consequences, are more proactive in implementing policies and carrying out investments outlined in Urban Adaptation Plans (UAP). On the other hand, medium-sized and small towns require adaptation as much as water; without it, the growing disparity between small towns and large urban areas becomes more noticeable. Without a good Adaptation Plan, various actions may not be fully effective, which can result in them not receiving support when applying for external funding. Furthermore, the lack of human capital, limited resources, and exclusion from UAP funding make even the development of such a plan a barrier for small towns with just a few thousand inhabitants. Success in this area can come from cross-sector collaboration. Large companies with financial capital increasingly recognize the need for cooperation within the framework of corporate social responsibility. Broad ESG (Environmental, Social, and Governance) policies in businesses create entirely new, unconventional opportunities for small towns to secure funding for adaptation. ESG also allows companies to demonstrate their commitment to sustainable development and social responsibility, which is highly valued by investors, consumers, and local governments. As a result, it improves the company’s perception, transparency, social trust, and market position. For this reason, the presentation will showcase good practices in cross-sector cooperation and small retention solutions implemented by the Hydroni Foundation, which have been funded by private enterprises. The example of rain gardens implemented on the premises of Poznań's POSiR, co-financed by Aquanet Retencja, and the project supporting small retention in the Promno Landscape Park (Pobiedziska Municipality) will be discussed. The key part of the presentation will be the announcement and detailed discussion of the competition for funding the development of UAPs directed at all towns in Greater Poland. The competition, organized by the Hydroni Foundation, allows for the development, partial updates, or direct implementation of adaptation solutions and is fully financed by private funds. The call for applications is expected to open in late March or early April.

Because every drop matters

Following every raindrop that falls in the urban landscape has become not just a "best practice" but a necessity. Solutions start with the roof, where rainwater is collected and stored on blue-green roofs. This water can then be redirected to retention tanks, which will nourish greenery, including trees, that help lower temperatures. Excess water can infiltrate into groundwater through retention-infiltration tanks. Such "in-situ" solutions bring tangible benefits not only in terms of social and health improvements but also contribute to increased safety by reducing the risk of stormwater drainage network overflow. Environmental impact reduction starts at the production stage, as most solutions are made from recycled materials. Wavin's approach to rainwater is a comprehensive perspective on the world's most valuable resource. The foundation of our approach to rainwater utilization lies in increasing urban resilience to climate change. How should we change the way we effectively manage available water to ensure that precious raindrops are utilized and not lost in the drainage system? How can we mitigate the negative effects of intense rainfall in urbanized areas? These and other questions inspire Wavin's solutions.

Awareness of the Importance and Development of Green-Blue Infrastructure in Urban Management

During the presentation, I will share the results of research conducted on behalf of the Upper Silesian-Zagłębie Metropolis (GZM) in the second half of 2024. The study encompassed 40 cities and municipalities within the Metropolis and focused on the awareness and development of green-blue infrastructure in urban management. The participants included residents, as well as mayors, municipal leaders, and city presidents. The analysis of survey responses revealed that residents recognize the need for the development of green-blue infrastructure and consider it valuable, citing various arguments that were examined in detail during the study. I approach the topic of green-blue infrastructure from both theoretical and practical perspectives. As an Assistant Professor at the WSB Academy in Dąbrowa Górnicza, I conduct academic research on this subject. Additionally, I serve as Deputy Mayor of Czechowice-Dziedzice, where I oversee the implementation of green-blue infrastructure projects, including those co-funded by Norwegian and European Union grants. Recently, we have commissioned five retention basins and six rain gardens. In the presentation, I will share both the research findings and practical experiences in managing stormwater in urban spaces.

Lunch

Do microgrants for green-blue infrastructure make sense? How to obtain and implement them?

One could jokingly say that in Polish cities, local programs supporting rainwater utilization, retention and infiltration, rain gardens, pocket parks, and the renaturalization of small watercourses are springing up like mushrooms after the rain. These programs are delivering results, which can be seen on the Retention Map (https://manifestklimatyczny.pl/mala-retencja-mapa/), where over 2,000 reported examples of various types of retention projects are currently listed, with a total capacity exceeding 0.7 million cubic meters of water. Perhaps this is just the tip of the iceberg. Regardless, it is always worth asking: Is this a lot or a little? And what more can we do to retain even more rainwater at the point of precipitation? From a purely numerical perspective, it is still very little! Poland’s most well-known and largest flood retention reservoir, Racibórz Dolny, which saved Opole and Wrocław from flooding in September 2024, has a maximum capacity of 185 million cubic meters. Moreover, if we divide the 0.7 million cubic meters of small-scale retention by Poland’s total land area (311,888 km²), we get an equivalent rainfall depth of just 0.002 mm. The number improves only slightly if we consider that urban areas cover about 7% of the country—even then, the equivalent rainfall depth would be just 0.03 mm, a value within the margin of error of modern rain gauges. So, is distributed retention really worth pursuing? Would it be better to centralize public funds and build another large retention reservoir instead? Or perhaps the real goal is not just about constructing retention basins or rain gardens, but rather about building human capital around such initiatives and promoting climate adaptation awareness? Maybe retention should be close to the people, so they understand that it costs not only to create but also to maintain it every year? These are the key questions we aim to answer during this debate. We also want to ask experts and practitioners involved in such programs how to smartly apply for micro-grants for retention projects and how to implement them effectively. We invite you to join this debate! Although it is the last session of the conference, we assure you that it is a case of "last but not least"!
