As many other places in Poland, cities and municipalities of our Metropolis must face the challenges of adapting to the changing climate. One of the key challenges is the rainwater management. When there is too much rainwater \u2013 there is flooding, when there is too little \u2013 lawns get dry, tree leaves become yellow and we walk through dusty and heated streets. The most effective action is managing rainwater in the place where it falls on the ground. The safest and cheapest is to think smart about our surroundings and not about expensive infrastructure. On this website we would like to encourage you to join us in caring about the safety and comfort of life in our city, in thinking about the rainwater.<\/strong><\/p>\n

We suggest you a few solutions which you may apply at your own house or in its surroundings in order to improve the state of the environment in your close vicinity. The small initiatives such as rain gardens, small ponds, water barrel under gutter, or removing excessively, and often unnecessarily, sealed off surfaces and their replacement with those water permeable ones \u2013 if there are hundreds or thousands of them, then together they will bring the expected effect.<\/p>\n

Najwa\u017cniejsze dla nas w gospodarowaniu wod\u0105 deszczow\u0105 w miastach i przystosowaniu ich na zmiany klimatyczne i anomalia pogodowe jest zagospodarowanie deszczu w miejscu gdzie on spada na ziemi\u0119. Istotne jest, by dzia\u0142ania by\u0142y podejmowane na ka\u017cdym poziomie: od pojedynczych nieruchomo\u015bci \u2013 przez mieszka\u0144c\u00f3w, po tereny miejskie \u2013 poprzez samorz\u0105dy. Gdy zadbamy o tereny miast i nie b\u0119dziemy ich nadmiernie \u201euszczelnia\u0107\u201d tworz\u0105c efekt tzw. \u201ebetonozy\u201d, gdy spowodujemy, \u017ce deszcz zamiast b\u0142yskawicznie odp\u0142ywa\u0107 po betonowych powierzchniach, b\u0119dzie mia\u0142 szans\u0119 powoli wsi\u0105ka\u0107, ograniczymy powodzie, zasilimy wody gruntowe przeciwdzia\u0142aj\u0105c usychaniu drzew i trawnik\u00f3w, ograniczymy potrzeb\u0119 ingerowania w naturalne rzeki, a mo\u017ce nawet przywr\u00f3cimy \u2013 jak to dzieje si\u0119 w wielu miastach na \u015bwiecie \u2013 nasze miejskie cieki mieszka\u0144com, jako tereny rekreacyjne i spacerowe. Zawr\u00f3\u0107my nasze miasta z powrotem frontem ku wodzie!<\/p>\n

What does that mean in practice? It means to have as little paving stones around houses as possible, it means departure from concreting market squares in cities and towns, using rainwater around houses to water the gardens, rinsing pavements and alleys with rainwater, and even using it to do laundry or flush toilets. We encourage you to treat water as it results from the Water Law \u2013 as a valuable resource we need to take care of, and not a threat we should get rid of.<\/p>\n

An interesting experience is to compare the amount of water generated in the water companies in cities with the amount of rainwater that falls on average within the area of a given city. As experts from RetencjaPL indicate, for the majority of cities, there is 3 to 4 times more rainwater falling compared to the amount of water supplied by water companies. What do we do with this precious resource? Do we harvest rainwater in order to use it or, unfortunately, we try to drain it as fast a possible from a given area treating it as a threat?<\/p>\n

What can we do as citizens? Water collected in domestic tanks can be used both outside and inside the building. The easiest way to use rainwater is to water the garden during dry seasons.<\/p>\n

But before we start using rainwater, let\u2019s start with the simplest and most effective activities. Follow the basic hierarchy of actions:\u00a01. Do not seal off! 2. Drain slowly! 3. Collect and use!<\/strong><\/p>\n

Do not seal off!<\/strong><\/p>\n

Sealing surfaces in cities causes increase in and acceleration of rainwater drainage. Sewage system does not have sufficient capacity for such large amounts of water during downpours. On the other hand, during droughts, yellowing lawns, drying trees and a low water level in wells indicate that there is not enough water in the ground \u2013 it is gone. What's the solution? Let us avoid paving, asphalting or concerting the ground in our neighbourhoods and yards. Let's try and keep the water where it falls to the ground, allowing it to soak in. It\u2019s the cheapest and best solution.<\/p>\n

Drain slowly!<\/strong><\/p>\n

When rainwater rapidly runs down the sealed surface of roofs, squares and streets, and into pipes, the risk of flooding increases dramatically. At the same time, the water is irreversibly lost: it does not soak into the ground, it does not supply lawns, gardens and trees in our cities. Slow drainage, with detaining the water in ponds, house gardens, ditches and recesses is the best way to prevent floods and droughts. Let us return natural circulation of water to urban ecosystems as well.<\/p>\n

Collect and use!<\/strong><\/p>\n

In recent years, the cities have faced a risk of flooding, but at the same time longer periods without rainfall. It is a good practice to allow water to soak in, and collect the surplus from roofs, squares and pavements in tanks, to be used for watering plants, washing streets or flushing toilets. Using rainwater brings significant savings. With aggregated effects of many smaller tanks, the spread retention will translate into calculable benefits for everyone. Re-using water will contribute to mitigating the effects of drought and improve microclimate.<\/p>\n
