“…They are Based on a detailed analysis and synthesis of the state of knowledge about stormwater management in Poland, it was found that the decision criteria (C j ) determining the choice of a specific stormwater management model, can be classified into six groups, including political, economic, social, technological, legal, and environmental criteria. The identified groups of criteria turned out to be identical to those indicated in the previous stage of the research as part of the political, economic, social, technological, legal, and environmental (PESTLE) analysis [25]. For this reason, it was assumed that the individual decision criteria were also the same as the factors determining the implementation of sustainable drainage systems, which were identified in the PESTLE analysis.…”

“…However, a comprehensive analysis of the rationality of the application of various design options of the drainage system also requires consideration of political and legal criteria. Earlier studies showed that they could have a significant impact on the implementation process of sustainable drainage systems and the selection of specific solutions [25]. It should be also noted that in Polish conditions the drainage of stormwater through underground canal systems and its quick discharge to the receiver is the dominant method of stormwater management [26].…”

Stormwater is a valuable resource, whose management in harmony with nature is one of the main challenges of modern water management. The problems encountered are additionally exacerbated by the lack of space for the development of sustainable drainage systems. For that reason, new housing estates should be designed considering efficient stormwater management. This paper assesses five stormwater management models to determine the statistically most appropriate model for managing stormwater in newly designed multi-family housing estates using multi-criteria analysis. Various options were assessed by means of the scoring method based on six groups of criteria (political, economic, social, technological, legal, and environmental). The research considered the different views and priorities of the experts involved in stormwater management in Poland. A survey conducted among them showed that the statistically most suitable way of managing stormwater is its infiltration into the ground with the use of infiltration basins or tanks. Only if the possibility of their application is excluded, should the application of other models of stormwater management, especially its retention, be considered. It is expected that the research results presented in this paper will be a guide for investors and developers, and their use will allow people who are not experts in the field of stormwater management to make appropriate decisions.

Investigation of Microbiological Quality Changes of Roof-Harvested Rainwater Stored in the Tanks

et al. 2021

View full text Add to dashboard Cite

Rainwater has been found to be a valuable source of drinking water in Europe, especially in such crisis situations as those caused by contamination of water uptake into water supply systems, large-scale floods or terrorist attacks (e.g., biological weapons). The microbiological quality of water plays a significant role, which is directly related to the potential health risks associated with harvested rainwater (including rainwater stored in the tanks). Microbial contamination is commonly found in rainwater. However, in the literature, detailed results of qualitative and quantitative microbiological assessments are sparse and remain unexplored. Therefore, the aim of this study was to investigate and analyze changes in the microbiological quality of roof-harvested rainwater stored in the tanks, depending on the collection conditions (type of roof surface), storage duration and season. Authors elucidate that conditions such as storage duration, the season in which rainwater is collected, the roof-like surface types and morphology of the catchment area highly affect rainwater quality. This study showed that rainwater harvested from a galvanized steel sheet roof had the best microbial quality, regarding the lowest number of bacteria, while rainwater from a flat roof covered with epoxy resin was the worst. Further, it was detected that rainwater collected in autumn and spring obtained the best microbiological quality. Moreover, a decrease in the number of bacteria was observed in correlation to storage duration. The water became sanitary safe after six weeks of storage at 12 °C. Its use for purposes requiring drinking water quality before six weeks of storage required disinfection.

“…For example, in more than 90% of Chinese cities, flood risk management is based on the use of traditional engineering infrastructure in the form of a traditional indoor stormwater drainage system, which, by definition, is intended to outflow urban discharges to the receiver as quickly as possible [24]. However, this way of dealing with excess stormwater is considered inefficient and does not have the characteristics of the facilities that are framed in the standards of sustainable urban development [25][26][27]. In order to reduce the risk of urban floods and the impact of urban growth, it is necessary to take measures aimed at increasing the efficiency of underground infrastructure management in cities [28][29][30][31].…”

To determine the effectiveness of the retention capacity utilization of traditional and innovative drainage systems equipped with damming partitions, the detailed model tests were carried out. The research results allowed indicating what values of the hydraulic parameter of the innovative drainage system should be adopted in order to effectively use the retention capacity of drainage collectors. The adoption of short distances between the LKR damming partitions and a high level of permissible rainfall of stormwater Hper turned out to be the most effective solution. In the most favorable conditions, the peak flow was reduced by up to 60% (717.46 dm3/s) compared to the values established in the traditional drainage system (1807.62 dm3/s). The benefits obtained resulted from the increased retention efficiency of the drainage system after equipping it with the damming partitions. It was found that the innovative system always achieved the maximum retention capacity with longer rainfall compared to the traditional system. In the real catchment area, an increase in the use of the retention capacity of the drainage system, from an initial value of 65% for a traditional system to almost 88% for an innovative system, was also found. Very large variability of the volume of accumulated stormwater in the conduits of the traditional and innovative drainage system was observed during rainfall, which generated the peak rainfall discharge in the innovative system. With rainfall of TRK duration, the innovative system accumulated up to 746.50 m3 more stormwater compared to a traditional system, which was 49.2% of the total retention capacity of the drainage system, with a value of 1515.76 m3. The approach to reduce the growing flood risk in cities provided the right approach to long-term urban drainage system planning, especially since traditional drainage systems are still the leading way to transport stormwater in cities. In addition, the innovative sewage system gives the possibility of favorable cooperation with any objects (LID) and retention tanks with any hydraulic model. The implementation of an innovative system allows achieving significant financial savings and reducing the need to reserve areas designated for infrastructure investments.
