During the conference, we will start a real dialogue of stakeholders of the development of the agglomeration, aimed at coordinating the management of rainwater with the development and transformations of our cities. Within this block, we will reach for inspirational examples of practices from the country and abroad on various scales, which prove that water is a resource conditioning the proper development of all cities.

This presentation will introduce how I think about rainwater management and how it fits into the way we should look at cities and changing climatic extremes. This includes greater clarity of water governance across the water cycle, thinking through about system of system thinking (rather than considering rainwater management in isolation) and ensuring the scale at which theses extremes are assessed considers the catchment rather than the city boundary scale. It will include examples from UK, Ireland and USA and will introduce the latest way in which we are looking at rainwater management in the rural and upper parts of catchments through Natural Flood Management.

Both water and space are today goods of increasing value and importance. Their resources are shrinking, due to expansive development policy, the element of which means intense and aggressive urbanization. Responsible spatial planning is primarily aimed at providing people with high quality of life –  shaping a healthy, safe and risk-free environment that provides everyone with freedom. It is easy to deduce that space planning, especially in highly urbanized areas, is a complex and multidimensional process in which the need for sustainable development and the use of solutions based on natural ecosystem processes have been increasingly accentuated in recent years. Among them, one of the most important is to consider the problem of retention and the use of rainwater potential, and this applies to practically every dimension – from the architectural scale, scale of the estate and the city to the scale of the country and even the continent. In the water cycle in the environment, many sensitive places of flow, evaporation and accumulation can – and for an increased positive effect – should be taken into account by spatial planning instruments. Unfortunately, spatial planning in Poland has for a long time remained a “separate” domain, separated from many important issues that were planned in the sector, which also applies to water management. Today’s challenges do not allow for such an approach in planning anymore and require a holistic approach that takes into account complex natural processes, sustained development and numerous needs of human functioning in the environment. In this context, the retention problem can no longer be perceived only as a technical-engineering or management issue, but becomes an important issue of the planning process, constituting one of the elements in the integrated approach. This should be so especially because today’s responsible management of water, more than ever before, is a direct response to one of the most important civilizational threats that is global climate change.

Increasing retention is one of the tools to reduce the risk of flooding. The presentation presents the results of the team of experts, led under the direction of the author of the presentation under the Flood Safety Program of the Vistula River Basin and later attempts to apply results in professional practice. It contains proposals for the principles of designating areas requiring specific solutions in the field of rainwater management in the documents of the spatial planning system. It also presents ways of taking into account the risk related to the existence of such areas in specific arrangements of planning documents, underlining the limitations resulting from system solutions.

During the presentation the executed retention facilities of the State Forests on the outskirts of the agglomeration will be presented on the example of the activities of the Regional Directorate of State Forests in Wrocław.

There will also be presented retention projects in the implemented Millennium Park in Wrocław on the Ślęza River and implemented on the new housing estate in Siechnice near Wrocław.

Water – the most valuable resource on earth and the most widespread substance in nature. It occupies as much as 72% of our planet’s surface, which could suggest that we have it in abundance. In practice, it turns out that only 0.4% of water resources is suitable for use as drinking water.
In 2015, UNICEF reported that nearly 750 million people on our planet have no access to drinking water, and in 2018 BBC television published a list of 11 agglomerations around the world faced with the threat of a lack of drinking water – among them exotic Sao Paulo, Bangalore, Jakarta , Mexico City, Cape Town, Beijing or Cairo, but also … London (contrary to the popular opinion that it is a city of continuous rainfall, in recent decades there is less rainfall than in Paris or New York). Polish cities and villages are also increasingly struggling with the problem of scarcity of water. We also know that the specificity of short-term and intense rainfall raises the risk of flooding. That is why it is so important to manage wisely and responsibly the resources of available water.
On the other hand, water in the public spaces of cities has an impact on the quality of life and the satisfaction of residents. Squares and parks with fountains are very popular, and the quality of public spaces with green and blue infrastructure is today an important determinant of the effectiveness of local governments.
Educational Water Parks HYDROFUN is the answer to the need for education in the field of rational use of water and an attractive public space in which the main actor is water. Hydrofun is a recreation and educational space, where children and teenagers can in an attractive way learn about issues related to retention and use of rainwater and hydrotechnical devices. They have the opportunity to check how the Archimedean screw, water dam, Pelton turbine or water mill works. The whole system uses, of course, rainwater retained in the reservoir, which further enhances educational values. Of course, an integral part of the system is also a management and monitoring system that guarantees users full control over the operation of devices.

Similar water parks can be found in Prague, Vienna or Germany, and their integration with the public space of city squares or parks makes them extremely popular.

Today no one has any doubts that it is worth investing in learning through play. In Poland, science centers such as Warsaw’s Copernicus, the Gdynia Experiment or the Gdansk Hevelianum are very successful. Each such center is the will and determination of local government, which finances or co-finance such projects. Educational water parks can perfectly complement the educational offer in our cities, as is the case with our southern and western neighbors.

Taking advantage of the presence of a wide range of Polish and foreign rainwater stakeholders, as part of the second session of the conference, we will attempt to work out the foundations of national standards based on experience from Europe and the world.

The presentation presents key issues and effects of work carried out within the framework of the Bydgoszcz project entitled “Bydgoszcz retention + 2050”. It is a summary of previous activities covering the most important areas related to the management of rainwater and snowmelt. After the modernization of the rainwater drainage system and the adaptation of the sewage network to climate change in the city of Bydgoszcz – the creation of standards for rainwater and snowmelt was undertaken. This is another important step in the verification of Bydgoszcz achievements. Undertaking practical issues related to the country’s largest project on rainwater, preparing “guidelines” related to their development – this is another pioneering initiative of the Bydgoszcz Waterworks. This project is an achievement and experience from four years of implementation, and the undertaking of the development of Bydgoszcz standards for rainwater is a unique initiative on the national scale.

The presentation shows the Bydgoszcz’s understanding of standards and the it’s path – from concept to implementation. It refers to original undertakings – author’s publications made before World War II, which inspired the undertaking of this task. This project is addressed to many environments and is in line with the needs of the water supply industry, which is the prospect of takeover and management of rainwater. He describes problem areas in rainwater management in Poland, contributing to the development of the first version of Polish standards for rainwater containing good practices in this area.

The presentation also shows the standards for rainwater and snowmelt – modeling, design, construction and operation developed at the second scientific and technical conference “Bydgoska retencja + 2050”. These standards were based on the proposals made by Bydgoszcz solutions which were developed and coordinated by MWiK employees along with numerous consultations with experts from these environments in Poland, who have their own experience and achievements in this area.

Thanks to the innovative formula of interactive workshops – the second Bydgoszcz retention conference + 2050 created creative conditions for discussion in eight working groups, where verification of presented standards proposals occured. The materials that have been developed contain “guidelines” that are good practices in rainwater management. These materials will be published for use in other cities, and we treat the resulting materials as the contribution of Bydgoszcz Waterworks to the development of the industry.

We assume that rainwater standards are a multi-stage project in which Bydgoszcz achievements will be developed further with other centers. The next stage is the third conference planned in 2019 from the series Bydgoszcz retention +2050.

We all know that rainwater is a resource that we can not waste. Rainwater tanks for deliberate use may reduce rainwater runoff in the annual balance and reduce drinking water consumption accordingly. An open surface of water, e.g. a pond, can facilitate the evaporation of part of the drained rainwater, thus exerting a beneficial effect on the quantity balance of water. In addition, the evaporating water contributes to reducing thermal stress in the city and reducing heat islands. In the case of limited space, which is certainly urban development, it is necessary to anticipate not only reservoirs and open ditches, but also – and perhaps above all – pay attention to underground infrastructure.

To ensure the long-term viability of such systems, it is necessary to ensure standards for mechanical durability of solutions, cleaning and inspection possibilities, ensuring rainwater quality introduced into groundwater or other receivers, and thus quality assessment of collected water. However, it is important to create clear methods for calculating retention and drainage systems and a catalog of technical solutions that can form the basis for engineering projects.

In several Polish cities, standards in the field of greenery are implemented. The latest such document is Standards for greenery development in Łódź, developed in 2018 by the team of the Association of Landscape Architecture (SAK), edited by Łukasz Dworniczak and Piotr Reda.

The thematic scope of these standards includes the entire process of shaping urban greenery in the chronological order: from investment preparation, through existing greenery protection standards, new greenery design, implementation – all the way to the standards of its maintenance (operation).

One of the elements of standards at all these levels is the management of rainwater in green areas. The standards prepared by the SAK team covers the problems of solutions improving water retention in green areas in the aspects of: obtaining rainwater; its distribution, collection and infiltration as well as ways of managing and maintaining green areas, to improve water retention.

Further joint work of landscape architects and specialists dealing in rainwater management is necessary to create consistent standards for shaping the so-called green-blue infrastructure, including related green areas and water resources.

The construction of combined storm overflows has remained largely unchanged for over 50 years, with the simultaneous use of newer screening methods for solids. This presentation will show a new, innovative design that reduces floating solids on the screen by more than 80%.

How to avoid damage of dehydration and what is the most common cause?
What benefits does prefabrication give you? What conditions should be met for linear drainage to function as intended?
Incorrect installation of drainage results in lowering the functionality of the system and jeopardizing the safety of its users. Urgent deadlines and, at the same time, changing weather conditions are not conducive to preserving the quality, in particular to the installation of concrete elements. Prefabrication guarantees a constant procedure for the preparation of the raw material, in repeated conditions of temperature or air humidity and under strict control of the quality department.

For lunch, we invite you to the Time Exhibition Hall (vis a vis Audytorium).

As part of the third thematic session of the conference, we will address the topic of modern tools for rainwater management, encouraging participants to apply a completely new tooling workshop. Beginning with the exploitation or thorough change of its business model, let’s reach for the tools of the future.

Digitalization is a process that has come into our industry for good.
Data collection, processing and drawing conclusions is an integral part of rainwater management. In the era of Internet and mobile devices, the key challenge is to fit tools that will simplify our work.

How to manage this process?
What kind of challenges we can expect?
What is the prospect for the industry?

I will try to answer this questions during the session
“Challenges and perspectives of digital rainwater management”.

Climatic changes, including sea level rise and extreme rainfall events, increase the risk of flood events in coastal cities. Adding rapid urbanization and inadequate or inefficient drainage infrastructures to the equation may result in frequent and recurring inundations.

Avoiding the ineffective reactive management approaches from the past (build first – check consequences later), flood risk management should now follow a proactive, holistic, collaborative and digital approach, taking advantage of the best-available data, information, knowledge, and multiplicity of interoperable technological tools, empowering the decision-makers with real actionable information towards anticipated early warning and prompt response.

As an example of this philosophy, here we present an advanced flood modelling software (OpenFlows FLOOD) with a complete multi-scale 1D/2D approach, specifically designed for dynamic modelling of the complex array of interconnected processes related with urban, riverine and coastal systems. Digital information is managed in a Collaborative Digital Workflow: 3D reality mesh is processed from multiple drone surveys (ContextCapture), feeding into the flood modelling (OpenFlows FLOOD) and using the terrain as input to various analyses in a single review environment for visualization and presentation to stakeholders in an immersive and visually striking 3D interface (LumenRT). Some illustrative examples of this digital workflow will be presented.

Since anticipated detection and response are also critical aspects when managing hydrometeorological hazards such as flash floods or storm surges, situational awareness and early warning systems must be built upon a proper combination of monitoring and forecasting of the flood occurrence, intensity, and evolution of hydrometeorological extreme events, providing an operational synopsis of the entire system, as well as early anticipation of accurate hydro-meteorological conditions contributing to flood risk. In that sense, and following the same digital collaborative workflow described above, the flood model configuration should be used to feed a cloud-based solution able to provide realtime dynamic dashboards in a mobile-friendly web interface, and email reports or SMS alerts.

This conceptual approach will be demonstrated with an existing platform able to take advantage of the combination of automated data acquisition, advanced numerical models (atmospheric / rainfall, OpenFlows FLOOD: watershed / surface runoff + stormwater sewage network + coastal circulation + waves + water quality), operational data analytics and data management technologies, delivering comprehensive and integrated real-time platform towards enhanced situational awareness and decision support.

These automated and collaborative digital workflows are the fastest and most efficient ways to promote data-driven, valid, effective and smart decisions in multiple time scales, reducing the risks of inadequate and unsustainable choices involving flood management and associated infrastructures.

Precipitation data is one of the most important input parameters in urban storm water management and forms the basis for all water management related decisions. Precipitation data is used for the design of technical structures like sewage water channels, retentions areas or spillways. Historically, for this purpose long-term precipitation data are used in combination with precipitation forecasting models to calculate the so-called design storms, which result in storm water atlases like the German KOSTRA atlas or the Polish PANDA atlas.

These design storms are frequently not very accurate and lead to underestimation of short-term storm water events for the following reasons:

• Not considering specific orographic characteristics of small-scale urban water sheds
• Data quality of available precipitation data
• No precipitation station with long-term recording available locally
• Due to averaging/aggregation historic data of extreme short-term events is not available

The use of radar-based precipitation data has become more and more important to improve monitoring and forecast quality in case of flooding as well as for the post-processing of storm water events. But experience has shown, that radar products offered by national meteorological services lack the timely or spatial resolution and/or necessary accuracy during a storm water event. For example, the German Weather Service (DWD) provides calibrated precipitation data only with an hourly update which is in many situations not enough to respond appropriately to storm water events. Radar data products with higher timely resolution leave it to the end user to calculate precipitation intensities.

All the above-mentioned leads to the conclusion that there is still a strong need for small scale local and regional precipitation monitoring networks to significantly improve the data base for design tasks, to improve the weather radar outputs and to design an efficient early warning system for the public:

• Growing demand for highly available, high-resolution and homogeneous precipitation data
• Need of ground-based precipitation data to optimize weather radar information
• State-of-the-art sensor technology for precipitation monitoring

This trend will be amplified in the future, if online and high-resolution precipitation data is used for the automatic or semi-automatic control of water related technical infrastructure.

Bearing in mind the significant impact of rainfall on the operation and exploatation of the sewage system in the city of Wrocławas well as the conduct of the wastewater treatment process, MPWiK S.A. in Wrocław constantly monitors the intensity and duration of precipitation of rainfalls using its own rain gauge network.

The presentation concerns the use of rain data in the daily work of MPWiK S.A. in Wroclaw, among others for: building a hydraulic model of a sewerage network, operating a city dehydration system (reports, classification of precipitation), settling accounts with the receiver’s manager and performing scientific works (engineering, master’s and doctoral). In addition, the spatial layout of the rain gauge stations will be presented which allows the monitoring of the Wroclaw’s rainfall field.

The evening gala will take place at the Great Armory at Targ Węglowy 6 in Gdańsk.

Admission to the Gala only on presentation of the Gala participant ID (the identifier issued on the basis of the application in the registration form).

At the “Stormwater Poland 2019” conference, Joanne will present the challenges and opportunities for financing projects under urban climate resilience programs

Responsibility for rainwater drainage systems belongs to many different entities: from government agencies and water supply companies to developers. The currently added s114A WIA enables water and sewage companies to build a sustainable drainage system if it is to relieve the sewerage system. This presentation will present the resulting responsibilities and discuss the joint long-term industry approach on stormwater systems in the UK.

The maintenance and management of the rainwater and meltwater management system rests in large part on local government units as one of the public tasks they perform. In terms of belonging to the local government, this task is therefore financed from public funds. In the existing Polish practice, it was generally assumed that support for activities related to water management in a broad sense does not involve granting public aid. Recent legislative changes, however, require a re-examination of this issue, especially in the area of rainwater and meltwater management.

As part of the presentation, the notion of state aid and its specificity in the water management sector will be briefly presented. The issue of the difficulties of municipal water and sewage companies, which lost the opportunity to cover costs generated in connection with the management of rainwater and snowmelt, within the tariff, will also be discussed. A review of possible institutional forms of management of rainwater and meltwater management systems will also be carried out, with an indication of risk areas from the perspective of public aid.

The starting point is the analysis of the case of an existing production and storage facility annually affected by increasingly higher fees associated with the discharge of rainwater to the existing sewage infrastructure and the selection of the correct system for the collection of rainwater (linear drainage of polymer concrete), pre-treatment (separators of oil derivatives) and drainage of water in drainage boxes in this plant.

Rainwater management is a real managerial challenge. In the 5th conference block in the formula of a wide discussion panel with the participation of high-class managers, we will address the challenges faced by managers of drainage systems.

Water and sewage management is one of the environmental components and an important area when it comes to the integrated approach in managing environmental issues in an industrial plant. The preparation of water for production processes and treatment of sewage resulting from these processes may constitute even from 30 to 50% of the energy demand of the entire plant. At the same time, this area has a significant impact on the local environment and residents. An important issue in the field of water and sewage management due to the changing and tightening legal provisions forcing the need to take action responding to challenges and sometimes often designing individualized solutions, due to the specificity of production and local conditions are rainwater and drainage.

Due to the presence of petroleum products on the premises, they must undergo an independent process of their mechanical purification also in CPI separators. It should be noted that they account for about 50% of all sewage flowing into the Central Sewage Treatment Plant. It is important to manage these waters during heavy rains and use them for economic and fire-fighting processes.

Appropriate innovative management processes in this area will, in addition to reducing the amount of water taken in and sewage discharged, also minimize the impact on the environment, improve efficiency and energy indicators and improve product benchmarks of the organization, supporting the building of competitive advantage

Do you need a media campaign to pay attention to the problem and possibilities to solve it? The examples that were successfully implemented in Bydgoszcz during the promotion of “Bydgoszcz water” confirm that such campaigns are very useful in overcoming myths and habits. It’s just that they must be long-term … and well-thought-out. If we talk about prices, it is not enough to deny that water is not the most expensive in the country. But the paradox is that … it’s enough to formulate the slogan so that people will immediately believe it. And then repeatedly repeated them in various contexts. In turn – when we talk about the quality of this water – it is often enough to show that nothing is floating in it, that it doesn’t smell bad and people are ready to accept that this water is safe for health.

Later, a cycle of educational TV programs was created. “Bydgoska Water”, and the whole was crowned by a nationwide swimming competition on the Brda – the only competition in Poland organized on the open river – also under the name “Bydgoska Water”.

Can experience from water promotion be transferred to the promotion of rain projects? Definitely yes – because here we are dealing with myths and the necessity of overcoming barriers. And those that are the most difficult to overcome – because they are mental. It is easier to think that the rainwater drainage is to “absorb” all the water from the torrential rain, than to admit that it does not have to be so that it rains … it floods us.

This second thinking means that sometimes you have to give up comforts, replace simple and popular solutions – more labor-intensive, far from the previous schemes. It is much easier to accept that you have to pay “some rain tax” (because someone once wrote this unhappily) for falling from the sky, and breaking down because of it … than letting yourself think that when I take my own initiative and I will limit the possibility of flooding with my participation, I can not pay for the use of rainwater drainage at all. Or pay less than a neighbour who did nothing about it.

What can we do to convince our neighbour to also begin to act and think in a new way? At first, it may be interesting to get a new idea and to propose a series of programs to expand knowledge. “But what? Rainy H20 “. Then – you can offer him a “Green and Blue Infrastructure Catalog” (containing guidelines and solutions), which is to serve as a guide to finding the simplest ways to manage the excess of rainwater. You can also give him a link to a website that will try to convince him that excess rain can simply be converted into profit. What is important – one-time interest in all these will not bring the expected results. That is why we are talking about the need for cyclical operations, and this requirement is fulfilled, among others media campaigns.

The presentation explains the EBC’s European benchmarking program, which covers activities related to drinking water, sewage management and – although to a very limited extent – rainwater activities (urban drainage).

As in the case of the EBC program, there is little effort around the world to compare storm water systems. The dense and frequent rainfall caused by climate change, increases the need for better rainwater management in cities. The development of a specific stormwater comparison analysis module, including a set of relevant performance indicators based on the strategic objectives of cities, may be the next step to support them in achieving a sustainable “rain-resistance” status.

Proper management of rainwater allows it to be stored and reused, for example for irrigation in the dry season and for cooling the temperature in the city. This leads to improvement of the air quality in the city.

The workshops will consist of:

• a presentation part, in which participants learn about the specificity of retention green roof systems that serve rainwater management in urban areas and issues related to the design, construction and management of Hydrozone retention reservoirs, modern technologies used in rainfall measurements.

• a practical part, in which participants will take part in the construction of a green retention roof on the Hydrozone reservoir and will also have the opportunity to learn about Hydrozone technology and devices as well as systems related to rainwater management and measurement.

The workshops present the essence of cooperation between many industries from the concept stage to the final management of rainwater soultions . The presented cases eliminate the effects of climate change such as heat islands, water shortages in the summer or heavy rainstorms.

Thanks to a theoretical and practical session in a multi-disciplinary group of specialists and enthusiasts, each participant will enrich his knowledge and thus his offer.

Classes will be held at the Ecol-Unicon production facility

The organizer provides transport of participants to the place of workshops, coffee service and lunch.
