Opis:
Over the last decade, Poland has witnessed a statutory change in the definition of rainwater. It stopped being regarded as wastewater. Municipalities in Poland have developed different models for rainwater management and various ways of financing them. The aim of the study is to identify and to describe the most important elements of rainwater management models in Poland with the use of operators. It focused not only on constitutive features of the system, but also on financial aspects, such as fees and investments (with the omission of fiscal ones). The study helped to identify three organisationally distinguishable operator models and indicated strengths and weaknesses of each of them. Such a systematic and structured analysis lays the groundwork for the assessment of these models and enables other municipalities to make a conscious decision on which model to implement.
W ostatnim dziesięcioleciu w Polsce została zmieniona definicja wód opadowych. Przestały być ściekiem. Miasta w Polsce wypracowywały różne modele zarządzania wodami opadowymi i ich finansowania. Celem badania była identyfikacja i opisanie najważniejszych elementów modeli zagospodarowania wód opadowych w Polsce z wykorzystaniem operatorów. Skupiono się nie tylko na cechach konstytuujących system, ale przede wszystkim na aspektach finansowych takich jak opłaty i inwestycje (z pominięciem fiskalnych). Udało się zidentyfikować trzy różniące się od siebie organizacyjnie modele operatorskie oraz wskazano słabe i mocne strony każdego z nich. Tak przeprowadzona systematyczna i ustrukturyzowana analiza stwarza podstawy do oceniania tych modeli i umożliwia innym miastom świadomy wybór modelu do wdrożenia.

Opis:
Modern city development requires increasing investments in so-called green and blue infrastructure. Water deficits and frequent droughts are a motivation for the introduction of economic water management and rainwater retention. Urban areas, which are often intensively developed and sealed, have lost their natural ability to retain rainwater. This is often the cause of urban floods that occur as a result of intense rainfall events, the intensity of which exceeds the capacity of urban drainage systems. These problems are caused by low surface and soil retention. These negative phenomena force us to take certain actions related to urban hydrology, such as determining catchments in urban areas and capturing rainwater. Town and city management must also take into account the functional and aesthetic aspects with the aim to improve the life quality of residents. Rainwater management on site of the rainfall allows to combine sustainable water management with the creation of places characterized by high aesthetic and functional value. The paper outlines the policy of the city of Wrocław with respect to rainwater management and presents the proposed solutions for a selected street, large-surface parking lot and a city square. Calculating the rainfall amount correctly and then preparing a land management design allows to use rainwater in creating attractive recreation areas.

Opis:
Anthropopressure is considered as one of the most important causes of disorder of natural water relations in the environment and impoverishment of the landscape. This is particularly evident in urban areas, where the degree of builtup areas and participation of impervious surfaces are still increasing. The result of such processes are extreme phenomena – more frequent droughts and floods. One way to keep a good state of water resources in urban catchments is creating retention and infiltration of rainwater. The paper presents examples of sustainable rainwater management that determine change of the face of the city and increase its friendliness towards the environment.

Opis:
Since March 1994, the Institut de Tecniques Energetiques (INTE) of the Universitat Politecnica de Catalunya (UPC), has been measuring environmental gamma dose rate and the airborne radon concentration levels outdoors, at the ESCRA Station, which is located in Barcelona. ESCRA simultaneously measures several meteorological parameters as well. As it is well known, the gamma dose rate suffers noticeable increments during rain intervals, which in our case range from 10% up to 40%, mainly caused by the deposition of the radon daughters 214Bi and 214Pb. These increments do not seem to be correlated with rainrate, rain interval duration, precipitation volume, or other meteorological parameters. In order to develop models that explain the observed dose enhancement, it is interesting to determine the concentration of the gamma emitters in rainwater and, due to the relative short half life of the two nuclides mentioned above, this must be done as it rains. To this end, we have developed an on-line gamma spectroscopy system for rainwater. The operation of this device, which has been automated by means of a LabView program, consists of the following steps: first, 250 cm3 of water is collected and, if the rainrate is high enough, is transferred to the measurement tank, a Marinelly-like container located underneath a HPGe solid state detector. All the system is surrounded by a lead shield. Preliminary measurements carried out with this device yielded radon daughter concentrations ranging from 50 Bq/l up to 1600 Bq/l.

Opis:
The aim of the study was to find out whether the climate of southern Poland allows for removing rainwater from industrial areas by evaporation from roof surfaces. The study covered the premises of a Logistics Centre with an approximate area of 34 hectares, located in the catchment of the Wedonka stream and in the region of water intake for Kraków at the Rudawa river. In the future, the Centre will comprise nine large warehouses. Road traffic associated with the project will cause potential risks for groundwater and surface water of this protected area. Therefore, the Centre’s investor decided to evaporate rainwater from the premises. To establish advisability of this plan, the study team designed and built a unique experimental station consisting of experimental roof, a tank for collecting water for the sprinkler system, system for delivering, distributing and discharging water from the roof, measuring tilt tray, automatic meteorological station, and electronic devices for recording measurement data. The research on the experimental station was carried out from April to October in 2011 and 2012 and included continuous measurements of the volume of water supplied to and discharged from the roof. Moreover, the temperature of the roof and water in the tank and the number of important meteorological parameters were measured. The difference between supplied and discharged water, divided by the wetted surface of the roof, helped to determine thickness of the evaporation layer in millimeters. The study confirmed the possibility of removing potentially contaminated rainwater by evaporating it from roof surfaces of the Logistics Centre located near Kraków at an average rate of 5.9 dm3·m–2·d–1. However, due to high seasonal variability of rainfall and air temperature, it is necessary to temporarily collect water in an expansion tank of suitable capacity.

Growing areas of sealed surfaces, rising water needs due to industry development, increasing populations, and climatic changes affect precipitation patterns and form a vision of the future in which meteoric water storage may become almost an obligatory activity. The aim of this paper was to identify the amounts and, to some degree, the quality of microorganisms present in rainwater collected from different types of rooftops of utility buildings in the spring-summer season. Apart from the classic culture plate method complemented by flow cytometry. The results of performed analyses explicitly show that rainwater collected from rooftops and directly from air prove to be microbially contaminated to a substantial degree, which includes pathogenic coliforms and faecal streptococci. Waters collected after dry periods also contained bacteria like Clostridium perfingens. The findings rule out the possibility of using rainwater collected from roof surfaces of utility buildings before its treatment.

Opis:
In Bielsko-Biała (Poland), thanks to the initiative of the originator and architect, a green intensive roof was created on a shopping centre. This roof primarily serves as a garden that enhances the qualities of the residential area, but also as a means of absorbing some rainwater and slowing down the runoff. The water collects in the rainwater retention tank located under the building. Rainwater also evaporates, and its surface runoff is slowed down as it passes through the vegetation on the green intensive roof. This paper addresses some of the operational problems of a selected green roof. The Water Law introduces the obligation to pay charges for the reduction of natural terrain retention. Shopping centres usually occupy large areas of land, but their roofs are rarely used for rainwater management and the installation of biologically active surfaces. Green roofs undoubted advantage is the increase of biologically active surface in urban areas. It is also an oxygen- -producing surface as well as reducing urban heat islands and attractive place for honeybees and butterflies. The roof in question meets the requirements of a retention facility mentioned in the Water Law Act. It is a multifunctional system for rainwater management. The analysis suggests that the roof under study is not a self-sustaining ecosystem and requires human intervention.

Ilościowe regulowanie transportem ścieków, zwłaszcza deszczowych, jest procesem, który istotnie wpływa na efektywne wymiarowanie sieci kanalizacyjnych oraz obiektów i urządzeń zlokalizowanych na tych sieciach. Ponadto sterowanie natężeniami przepływu ścieków pozwala w sposób racjonalny wykorzystywać istniejącą przepustowość hydrauliczną kanałów je odprowadzających. Regulowanie natężenia przepływu ścieków deszczowych nabiera coraz większego znaczenia, gdyż wzrost udziału powierzchni szczelnych na terenach zurbanizowanych wpływa na zwiększenie ilości wód opadowych ujmowanych i odprowadzanych systemami kanalizacyjnymi.

Przedstawiono podsumowanie wyników wieloletnich badań stopnia zakwaszenia wód opadowych prowadzonych w siedmiu punktach zlokalizowanych wokół Bielska-Białej. Na każdym ze stanowisk czas badań wynosił około jednego roku. Badania prowadzono w latach 2002-2010. Zakres pH wód opadowych wahał się w granicach od 3,35 do 7,22. Większość próbek tego opadu, bo około 86% miało pH < 5,6, tj. poniżej naturalnego, świadczące o obecności w badanym opadzie substancji zakwaszających. W opadzie 47,6% prób stanowiły opady znacznie i silnie zakwaszone, tj. o pH < 4,5. Stwierdzono częstsze występowanie kwaśnych wód opadowych o pH < 5,6 niż w silnie uprzemysłowionej części województwa śląskiego. W badanym rejonie pH wód opadowych kształtują przede wszystkim zanieczyszczenia napływające z kierunku zachodniego i południowo-zachodniego oraz lokalne źródła ich emisji.
In the paper results of long-term studies on acidification of water precipitation conducted in seven research points located near Bielsko-Biała were introduced. In each point period of study lasted ca. 1 year. The research was performed in the years 2002-2010. The range of pH of precipitation varied between 3.35 to 7.22. Majority of precipitation samples, because approximately 86% had pH < 5.6 i.e. lower than natural level, which indicated the presence of acidifying substances. Amongst samples of precipitation 47.6% were significantly and strongly acidic i.e. pH < 4.5. The rainwater with pH < 5.6 was more frequent than in more industrialized part of Silesian voivodship. In the investigated area pH of precipitation is mainly under influence of pollution flowing from west and southern-west and local sources of its emission.

The aim of this study was to assess the impact of the reuse of purified wastewater from the wastewater treatment plant in the city of Settat on the physicochemical quality of agricultural soils compared to the agricultural soils irrigated by rainwater in the region of Chaouia in Morocco. The results obtained showed that despite the great fertilizing value of the purified wastewater, a slight increase in salinity was noted; they also reveal a significant difference in pH. The accumulation of sodium, total limestone and active limestone in the soil increased significantly in the soils irrigated by treated wastewater; in contrast, calcium increased significantly in the soils irrigated by rainwater.No significant differences were recorded for humidity, electrical conductivity, ammonium, nitrates, phosphorus, potassium, organic matter, total nitrogen or cation exchange capacity.

Opis:
Shopping centres usually occupy large areas of land development. However, their roofs are rarely used for purposes related to rainwater management and introduction of active biological surfaces. In Bielsko-Biała, thanks to the initiative of the originator and architect, an intense green roof was created on the rooftop of a shopping centre. In addition to the primary role of the roof as a garden that makes the housing estate more attractive, it also collects some of the rainwater and delays its outflow to the sewage system. Plants, shrubs and trees planted on the roof are watered almost exclusively with water collected in a tank located under the building, intended for retaining rainwater. These waters are pretreated before they reach the tank, i.e. they filter through the root layer of plants growing on the roof, and through the biologically active layer (substrate). This paper highlights some of the operating problems of the selected green roof. The authors focused on assessing the toxicity of rainwater flowing down from hardened surfaces on the roof of the shopping centre and the area occupied by the green roof. Relevant toxicity studies on these waters have been carried out in this regard. The research hypothesis that rainwater percolating through the selected soil material is not toxic and stimulates test plant growth was put forward. Tests of semichronic toxicity with the seeds of white mustard (Sinapis alba L.) prove that all the rainwater samples showed a stimulating effect on the test plant. The average root growth stimulation value during the period considered was –125%. It was confirmed that rainwater did not show toxic properties for white mustard seeds (Sinapis alba L.) and can be used for watering the garden constituting the green roof of a selected research facility. In the case of rainwater pH, it was found that the pH is adequate and has no toxic effect on the selected white mustard test plant (Sinapis alba L.). It confirms that the rainwater retained in this way can be used to water the green roof. The selected research facility meets the requirements set for green roofs.

Opis:
Zachodzące zmiany klimatyczne i systematyczne obniżanie się w Polsce poziomu wód gruntowych nie skłoniły podmiotów odpowiedzialnych do opracowania jednolitej strategii dotyczącej zagospodarowania wód pochodzących z opadów atmosferycznych, która określałaby cele i konieczne do podjęcia działania. Efektywne gospodarowanie w miastach takim zasobem wciąż nie jest w Polsce zjawiskiem powszechnym. W wyniku zaniechań znaczna ilość wód opadowych i roztopowych nie jest w ogóle wykorzystywana. W 2017 r. dokonano zmiany ustawy – Prawo wodne aby przeciwdziałać ich marnotrawstwu. Wprowadzone rozwiązania miały zachęcać do zmian w sposobie gospodarowania wodami, a także racjonalnego wykorzystywania. Kontrola NIK wykazała, że tak się nie stało.
The audit conducted by NIK, dedicated to management of rainwater and meltwa ter in urban areas, shows that, despite climate changes and the consistently lowering level of groundwater, a strategy for management of water from atmospheric precipi tation has not been developed to date. The activity of the Polish Waters State Holding (Polish: Państwowe Gospodarstwo Wodne Wody Polskie) related to the management of such waters, has not been systemic and mainly comprised its statutory tasks such as, among other, judicature related to issuing legal permissions and, what is more, in the majority of the audited entities irregularities have been found. Investments relat ed to management of rainwater and meltwater in urban areas were mostly realised by local self-government units, and they were mostly aimed at preventing local floods and permeations due to violent downpours. Only some cities dealt with possibilities to manage rainwater and meltwater and introduced incentives to encourage residents to collect and use this kind of water. The audit also showed that some cities channelled rainwater andmelt water without legal permissions, and unduly met their obligations to collect charges for reducing natural retention. Insufficient cooperation among local self-government units and the organisational units of the Polish Waters State Holding further reduced the effectiveness of the system of charges set forth in the law on water, which had been aimed to encourage lower channelling of rain water and melt water, and to introduce solutions to ensure natural retention preservation.

Opis:
The aim of the research was to create a draft concept for the management of rainwater from the area of a single-family housing estate through the use of retention and infiltration systems with the possibility of collecting rainwater on the surface or under its surface. These systems include: a storage reservoir, an absorbent trough, a rain garden, an infiltration basin, drainage boxes and root boxes. All devices have been designed in such a way that they harmonize with each other and create an extensive system of blue and green infrastructure, without overloading the sewage network. The amount of rainwater was also calculated and the planned devices were designed and dimensioned. The devices located in the estate were arranged in such a way that they could intercept water from every part of the drained area. They can hold a total of nearly 46.5 m3 of water at the same time. This gives a very high efficiency of operation in terms of protection of surface waters and retaining them at the place of their formation. Thanks to such a high absorbency of the devices used, the estate is able to work like a sponge. The accumulated water from the drained catchments is mostly drained directly into the soil profile. This has a positive effect on maintaining the appropriate quality and high level of groundwater. Water, infiltrating into the ground through drainage layers, undergoes natural pretreatment, limiting the migration of organic and mineral micro-pollutants. The applied infiltration allows to increase the efficiency of groundwater intakes without reducing their level excessively, and its maintenance is necessary to ensure an appropriate composition of these waters. Oxygenated water infiltrating the aquifer, which contains iron and manganese compounds, can oxidize sulphides to sulphates and dissolve ferric and manganese sulphates. This means an increase in costs and an extension of the purification and treatment process of the abstracted waters. The planned infiltration and retention system is of a landscape nature. It is related to the shape and development of the land surface and the directions of its use. At the same time, the systems used do not take up much space on the ground surface, give the impression of being natural, thanks to which the area around the buildings has become more attractive in terms of aesthetics and functional.

Genesis of rain sewage is connected with drainage of roads and objects linked with them. Its quality changes with flow intensity modification and rain duration. Devices used to rainwater treatment have great impact on environment. The aim of made research was evaluation of rainwater treatment effectiveness of selected separators located in Białystok. Storm water drainage is in 47,35% city area.
