Being aware of the unique local conditions, we plan to start our meeting with a session titled: Made in Silesia. In this part, we want to present specific projects regarding rainwater, increasing its retention and use on site in order to change the cities of Upper Silesia and Basin for a better future, and thus improve the standard of living of their inhabitants and make them resistant to progressive climate change. We want to show that such projects can be part of the overall transformation of the entire region and constitute a good role model in other parts of the country. In addition, this session is to demonstrate technologies and solutions in the field of rainwater that are created, produced or have their pioneering applications in this industrial heart of Poland. This session is also an opportunity to answer the question whether there are any measurable effects of the edition of the Stormwater Poland conference in Katowice in the previous year.

In the second block of the conference, entitled: Rainwater does not have to be a sewage! we want to address the issue of the impact of the quality of rainwater or snowmelt runoff on the waters of receivers. At this session, we want to deal with the seemingly unsolvable problem of combined sewage systems. We want the users to speak at the session, those, who did not escape this challenge, but were able to separate the combined sewage system even in the scale of a large city, obtained permits for the CSO operation in accordance with the current requirements of the Water Law or applied solutions limiting the number of overflows and their impact on water receivers. We would like to supplement these examples with the presentation of technical solutions that may help in increasing the retention capacity of combined sewage systems and reducing the number of overflows as well as reducing the overall load of pollutants discharged with rainwater and meltwater.
