Session 1

Silesian retention

Taking into consideration the location of the conference we would like to start the event with a session we called: Silesian retention. There are more than many reasons for such issue to be discussed all having one underlying statement that Silesia is a unique and demanding battlefield for stormwater in Poland. The Metropolitan Association of Upper Silesia and Dąbrowa Basin, which is a partner of the conference, is composed of 41 communes (including 26 rural communes) that take up over 2500 km2 with more than 2,200,000 people living, working, and studying there. This is a large metropolitan association that everyone connotes with the biggest industrial centre in Poland. This generates multiple challenges connected with stormwater escalated by the fact that the whole area is located on a drainage divide on the two largest Polish rives, which often means no access to the natural receivers of stormwater. Moreover, due to further industrialization of the area of Upper Silesia and Dąbrowa Basin region there have been many changes in hydrologic networks where pipes were laid in many rivers, reaches were changed or rivers canalised, and due to soil settlement their slopes and downfall directions changed, and new depression areas appeared. This becomes a difficult but fascinating challenge, which we would like to address together. We hope that during this session we will learn about the condition of stormwater management on the area of the Metropolitan Association of Upper Silesia and Dąbrowa Basin and about  possible improvement solutions. We also hope to present examples of using stormwater in remediation and renaturalisation of post-industrial areas that were applied abroad. Finally, our ambition is to show a different and lesser-known side of the area of Upper Silesia and Dąbrowa Basin region and the potential of using local solutions of blue-green infrastructure for mitigating climate change.

Session 2

A City with Climate

Following thing global act local motto we believe that the second session of the conference called A City with Climate will familiarise you with the activities of Ministry of Climate, National Fund for Environment Protection and Water Management that are already in progress or in planning phase, dedicated to retention development and rainwater management in Poland as well as preventing extreme weather phenomena. It should be remembered that Silesian Voivodeship is the area particularly vulnerable to torrential rain since large masses of humid air from the south of Europe inflow through Moravian Gate. It is our intention that through Moravian Gate not only rain but also good ideas on how to cope together with extreme weather phenomena such as droughts and torrential rain in the whole East-Central Europe should flow in. RetencjaPL had the pleasure to present PANDa Atlas, which at that time was still being developed, at COP24 conference in Katowice. In 2021 we would like to present, in the very same place, the completed version of PANDa atlas together with waterfolder.com, a spin-off internet portal, and demonstrate how the two contribute to the modernisation and immunisation of Polish stormwater systems to climate change.

Session 3

Road Drainage

The aforementioned Moravian Gate has played the role of a route connecting Poland with the south of Europe since time immemorial. It is therefore not a surprise that Silesian Voivodeship is truly a traffic junction of Poland. On the area of the Metropolitan Association of Upper Silesia and Dąbrowa Basin, besides the largest motorway traffic junction (at the crossing of motorways A1 and A4) three European routes and eight national routes run through this area. On top of that, there are several railway junctions, a several dozen of railway lines and the international Katowice Airport. We do hope that such advanced communication infrastructure will make your travel to the venue of the conference safe and pleasant. However, the aforementioned roads, trackage and runways are places where large runoffs form. That is why we have arrived with an idea for a separate session called Road Drainage. We would like to present during this session new technologies in this area, but most of all discuss the need for harmony in designing and operating road and urban drainage systems since, in most cases, the water from roads gets into cities. What should we do with it, how to retain and pretreat it, how to share the costs of operating stormwater systems on the verge of a city and transport route?

Speech and opening of the conference by the Minister of Climate and Environment

Blue-green infrastructure as a way to mitigate climate change. Metropolitan projects

GZM is the first and so far the only formal metropolis in Poland. It was established in July 2017 and implements many regional challenges for the 41 communes associated in it. These are primarily: the organization, integration and development of public transport, but also social and economic development and shaping the spatial order. The metropolis covers the central part of the Śląskie Voivodeship with an area of ​​2,500 km2 and about 2.3 million inhabitants. It is an extremely highly urbanized area. The Metropolis of Upper Silesia and Zagłębie belongs to the catchment area of ​​the Baltic Sea. The European watershed between the basins of the Vistula and Oder rivers runs through the center of the area. Water reservoirs in the GZM area are of anthropogenic origin as: - the effect of intended human activity, ie: post-exploitation reservoirs related to the surface exploitation of raw materials (excavations) and dam reservoirs created in river valleys; - a side effect of underground mining, i.e. reservoirs in subsidence basins. Most of these tanks are multifunctional. They play not only a natural and landscape role, but also flood protection, recreation and relaxation, and some are used for water sports or water supply.

Blue-Green Infrastructure in the Ruhr Metropolis

The Ruhr Metropolis has a long tradition in structural transition on it’s way to a green, sustainable and livable region. Current challenges include climate change, heat, drought, flood and heavy rain events in cities with largely sealed grounds. Green-blue Infrastructure provides multiple benefits to people and nature and strenghtens the resilience of cities and regions. The presentation will show regional solutions with a focus on strategic approach, regional governance and introduction of implementation measures.

The use of data in the optimization of rain system management for the municipality of Kolding in Denmark

In 2011, The BlueKolding utility in Kolding, Denmark implemented Veolia’s Hubgrade Performance Plant in the combined sewer network and wastewater treatment plant. It’s objective was to reduce combined sewer overflows (CSO), minimize the needed extension of basin volume as well as improve the operation of the wastewater treatment plants. This presentation will demonstrate how Hubgrade Performance Plant, using an integrated Plant/Network systems approach, can improve the overall performance of the entire sewage system by combining forecasts of the upstream urban drainage system with information from the wastewater treatment plant in a multi-objective control algorithm that benefits the whole waste water cycle.

Retention yesterday and today - retention systems based on two GRP pipe technologies

Do weather anomalies threaten the local community? Can we be afraid of flooding while living in cities? Is it worth investing in a sustainable ecosystem? How to secure urban areas and at the same time protect the natural environment? These are the questions we want to answer in our presentation at the Stormwater conference. We will tell you how it was done in Silesia region with the use of Amiblu products.

Summary of the session, questions from participants

A presentation on the monitoring of transport drainage

Why it's OK to panic - a few words about climate mechanisms

A synthetic look at climate shows that it is a delicate mechanism that may or may not be conducive to living conditions on the planet's surface. As part of the presentation, I will discuss the most important mechanisms governing the Earth's climate, broken down into extortions - that is, mechanisms from "outside" the climate system and feedback, i.e. the system's response to the extortion resulting from its internal dynamics. I will show that currently the greatest forcing and unprecedented in the history of the Earth is anthropopression, especially greenhouse gas emissions to the atmosphere, then I will show the arguments that the cascade of feedback caused by this extortion is a threat to the present form of life on our planet.

Separation of the combined sewage system and construction of a retention facility in Jarocin

In recent years, Jarocin has faced the increasing problem of overloading the combined sewage system. The sewage overflows that appeared more and more often threatened the very center of the city, and above all the area of ​​the market square with over 100-year-old historic tenement houses and the town hall. The rainwater has contributed to the degradation of many of these recently refurbished buildings. In order to prevent these problems and ensure an appropriate standard of sewage system to the inhabitants, a difficult challenge was undertaken, considered by many to be even impossible. It was decided to separate the combined sewerage system and put on retention in the very center of the city. These tasks were accomplished thanks to funding for the investment entitled "Organization of water and sewage management in the commune of Jarocin" received from the Operational Program Infrastructure and Environment awarded by the National Fund for Environmental Protection and Water Management in the amount of PLN 136 million. It was also a very big financial challenge for the city, as the total value of the project was PLN 280 million. One of the six tasks of the investment was "Reconstruction of the sanitary sewage system and the water supply network in Jarocin," including the management of rainwater and snowmelt in the very center of the city. A particular technical challenge of the project was the necessity to build two underground retention facilities in the very center of the city. These objects were made of GRP SUBOR winding pipes with a diameter of DN2800, made of polyester resins reinforced with glass fiber and filled with quartz sand. The first, smaller, 76 m-long object was built directly under the market square in an open trench. In the case of a larger facility, 200 m long, at ul. Wolności, it was necessary to use the trenchless method (microtunnelling). Interestingly, using microtunnelling, the DN2800 jacking pipes were installed along a bend with a radius of 600 m. The pipe supplier was Duko Inżynieria Sp z o.o., while the general contractor was a consortium of DROBUD S.A. companies. and WUPRINŻ S.A. Thanks to the implementation of the above-mentioned investments, the waterworks in Jarocin not only protect the city's monuments and improve the safety and comfort of life of its inhabitants, but also reduce the costs of the sewage disposal and treatment system in the long term. The problem of storm overflows ceases to be a significant issue now, and much less mixed rainwater is discharged into the treatment plant. Thanks to this, this great investment will bring measurable economic effects for the Jarciński waterworks and for the city's residents. The completed investment also has another dimension - it is the first step in building a new, blue and green face of the city of Jarocin. Preparations and implementation of further investments aimed at the restoration of the city center are already underway.

Implementation of a new stormwater management strategy and city development planning guidelines

My presentation will focus on implementing a new stormwater strategy and guidelines to the urban development process. I will brief you about Nacka’s way of working from a catchment area perspective while having water quality and the EU Water Framework Directive in focus. I will present concrete examples on blue-green infrastructure that we have developed and discuss the details of the design.

Organizing the rainwater management system in Katowice - Stage I and II

The subject of activity of Katowicka Infrastruktura Wodociągowo-Kanalizacyjna Sp. z o.o. is water and sewage management in the area of ​​its operation in the field of sewage systems, sanitary facilities, disposal and treatment of municipal wastewater and management of the water and sewage infrastructure owned by the company. The company develops the water and sewage infrastructure by performing tasks, including those related to the acquisition and management of funds, incl. Cohesion Fund for the modernization of the Katowice water and sewage system. On May 5, 2021, the Company concluded Agreement No. POIS.02.01.00-00-0004 / 20-00 with the National Fund for Environmental Protection and Water Management in Warsaw for co-financing of the Project "Organizing the stormwater management system in Katowice - Stage II", under Measure 2.1 Adaptation to climate change along with securing and increasing resistance to natural disasters, in particular natural disasters and environmental monitoring, Priority axis II "Environmental protection, including adaptation to climate change" of the Infrastructure and Environment Operational Program 2014 - 2020. The general objective of the project is to organize the drainage of rainwater in Katowice and to retain this water for reuse. The implementation of the objective will improve the condition of the natural environment. Currently, rainwater and snowmelt in Katowice are largely discharged through the combined sewage system. Therefore, they mix with sanitary sewage and are discharged into the environment via sewage treatment plants. Due to the age and overload of some elements of the combined sewage system, it is necessary to divide it into sanitary sewage system and rainwater sewage system. The main identified problems are the age of the network, the geological conditions of the foundation, the lack of tightness of the channels, including critical sections, insufficient self-cleaning speed of the collectors, resulting from inadequate falls, as well as frequent oversizing - in relation to its current load - the network built in the years of intensive industrial development. The implementation of the project is also particularly important due to the more and more frequent flooding resulting from violent and heavy rains resulting from climate change. Large cities with densely built-up buildings and a large sealed area are particularly vulnerable to the effects of this type of phenomena. The drainage and retention of as much rainwater as possible from housing estates ensures the safety of people, material goods and the environment, and prevents flooding. Moreover, due to the dominant number of combined sewerage networks and the extreme weather phenomena observed in recent years, mainly heavy rainfall, fluctuations in the amount of sewage flowing into the treatment plant can be significant. This results in a direct dilution of the incoming municipal waste water, deteriorating its quality and reducing the efficiency of the treatment plant. For this reason, it is necessary to invest in distribution networks, which makes it possible to relieve sanitary networks and sewage treatment plants, and opens the possibility of rainwater retention and re-use. The water retained in the reservoirs can be used, for example, for watering urban green areas. The material scope of Stage II of the Project covers 4 investment tasks and the planned total cost of the Project implementation is PLN 27,396,193.14. Pursuant to the agreement, the beneficiary will receive a grant for the implementation of the Project in the amount not exceeding PLN 14,199,246.43. As part of this project, it is planned to build approx. 2 km of rainwater sewage system and 9 underground storage tanks with a total capacity of 2.9 m3. The material scope of Stage I of the Project covers 6 investment tasks, and the planned total cost of the Project implementation is PLN 66,887,857.72. The company was granted a grant for the implementation of Stage I of the Project in the amount not exceeding PLN 34,086,014.90. As part of this project, 11 underground storage tanks (reinforced concrete and pipe) with a total capacity of almost 6.5 thousand m3 will be built, as well as over 7 km of rainwater drainage network to be built, rebuilt and renovated.

Copenhagen - a city friendly to people thanks to its green and blue infrastructure

677 / 5000 Wyniki tłumaczenia Copenhagen is a model example of a city that, following the catastrophic flooding caused by the torrential rain in 2011, introduced a comprehensive stormwater management plan based on blue and green infrastructure. The adopted "masterplan" consisted of over 300 projects, to be implemented within 25 years. In the presentation, I will talk about the process of adopting this plan and describe its long-term goals. In addition, we will have the opportunity to see selected projects from the last 10 years and see how they contributed both to increasing flood safety and improving the quality of public space in the city.

BlueHealth – how urban water improves our health and wellbeing

Many of Europe’s cities are built in, on or near water. Evidence from a number of scientific disciplines has demonstrated that these urban ‘blue spaces’ can enhance human health and wellbeing, and that these positive benefits are generated through a number of mechanisms. These benefits to health can be maximised by using evidence-based methods in the planning, design, maintenance and governance of our cities to improve the safety and quality of urban blue spaces, and by promoting safe public interaction with them.

Summary of the session, questions from participants

How to reconcile transport and city drainage?

Communication drainage in urban areas has to take into account several aspects: little space for infiltration, joint "use" of the rainwater drainage system with functions housing, industrial, etc., necessary preventing the negative effects of climate change through infiltration, retention and the creation of "ecological islands" promoting a return to the natural environment nature in urban areas. The natural environment also plays an important role here. The reconciliation of these various functions requires cooperation many fields of science and the use of new solutions technical.

From dehydration to retention. Catch the rain for Silesia

The idea behind investing in rainwater collection and retention systems in Silesia is to take care to restore rainwater to the natural environment, where rainfall occurs. Increasingly, systems are designed to be as close as possible to natural processes occurring in nature. In urban climates, it is not always possible to avoid waterproofing the surface, which is why systems that collect rainwater, as well as pre-treatment systems from harmful substances, which are washed away from paved surfaces with the run-off of surface water, are of key importance. Water collected and treated in this way can be, in an environmentally safe manner, transferred to management systems and returned to the natural circulation or reused.

Engineering objects in communication construction and their ecological functions

Engineering structures in communication construction perform a number of functions, mainly related to bridge crossings over rivers. Rivers and watercourses are often referred to as water obstacles, and bridges are crossings over water obstacles. Meanwhile, bridges and other engineering structures have additional functions related to ensuring the continuity of ecological corridors. Ecological corridors that form networks play a very important role in the movement of wild animals. The paper presents environmental issues related to the movement of animals along water courses and the principles of preparing engineering structures for animal migration. In addition to the classification of objects, the results of the monitoring of the use of underpasses for animals, the principles of their proper shaping as well as good and bad practices will be presented.

Speech on the activities of ZZM in Krakow on the projects of streets, squares and roads.

The City Greenery Board in Krakow is associated with Krakow's parks, squares and forests. However, when we analyze the undertaken investment tasks on the ZZM task list, we will find tasks related to the road space. At the beginning, just some of the pocket parks implemented by ZZM were located in the space of road plots, and over time, larger tasks appeared, such as the revitalization of Św. Ducha, reconstruction of ul. Grzegórzecka - Green Grzegórzecki Square or the revitalization of Kossak Square. This list also includes numerous smaller activities carried out jointly with residents and other urban units in the area of ​​roads previously occupied by cars. These activities testify to a change in thinking in planning and shaping public space in highly urbanized parts of the city. They respond to the need to adapt the city to climate change and to provide residents with friendly public spaces encouraging walking or using sustainable transport, as well as promoting the health of residents and improving the quality of the natural environment. This direction is also gaining support and acceptance of the inhabitants, despite the necessity to introduce restrictions on car traffic.

Adaptation to climate change on national roads in Poland

Roads are at the heart of climate change debate both for mitigation and adaptation. Road traffic was responsible for about 97% of Polish transport emissions in 2017; while roads are as well part of the affected by its impacts and those are only expected to increase. The joint GDDKiA-JASPERS presentation will focus on the needs to adapt to climate change by providing an overview of current climate change vulnerabilities of the national road network based on the analysis of a wide set of registered extreme weather impacts. It will also highlight potential future vulnerabilities and related impacts to finally propose an action plan for one of the key challenges of the sector and a current main priority of EU policies and financing.
