“…Akter and Ahmed (2015) conducted a study of the potential of rainwater harvesting in the urban area of Chittagong city in Bangladesh through hydrological modeling, concluding that the use could reduce 26% of the volume of rainwater that would be destined to the drainage system, making a use of 20 liters per inhabitant/day. Sanches Fernandes et al (2015), carried out a study of a rainwater harvesting system for use in non-drinking water purposes in the city of Mirandela, in the north of Portugal, where it was calculated the efficiency of the system at a value of 90%.…”

The study measures rainfall data to determine a rainwater harvesting coefficient revelant to rainwater harvesting and catchment projects assisted by non-parametric statistics tests, based on assumption that part of the total rainfall depth is discarded. The analyses of historical rainfall series shows that the city of Belem presents large potential to promote rainwater harvesting, with a rainy season and a less rainy season during the year. The results present an average of one rainfall event per day, from January 2001 to December 2011, and of which around 38% is used only for washing the rainwater harvesting system. The Anderson-Darling test revealed a non-adherence of the rainfall series to a normal distribution and according to the Mann-Kendall test, there was no significant trend in the evaluated series. After the calculation of the effective rainfall, determination of coefficients, application of the Anderson-Darling normality test and the Kruskal-Wallis variance test, it was proposed a rainwater harvesting coefficient of 0.78 for the city of Belém, Brasil.

“…In the first case, it can be assumed that the interest in the possibility of using these methods was compelled by the situation arising from the need to find technically and economically justified alternative sources of water. Research conducted in India [35], Bangladesh [36], Botswana [37] and Nigeria [38], focuses mainly on rainwater harvesting systems, and both individual solutions for these systems and their possible locations are analysed. Similar research has also been conducted in Great Britain [39], which was a consequence of the need for unconventional water sources in some parts of the country.…”

Progressing urbanisation is one of the key causes of environmental degradation. This problem also applies to stormwater management. For this reason, drainage infrastructures should be designed in harmony with nature and the decision for selecting a specific stormwater management system solution must not be taken on an ad-hoc or single-perspective basis. The purpose of this paper is to identify the criteria for selecting the best solution for a problem involving the selection of a stormwater management system, and to present a method that will enable all relevant criteria to be taken into account in the decision-making process. The developed decision problem structure takes into account all criteria related to the construction and operation of stormwater infrastructure, and its individual elements were identified based on the analysis and synthesis of information regarding the principles of stormwater management in Poland. The presented approach will allow for the taking into account of all, often mutually exclusive, criteria determining the choice of the stormwater management system option. This, in turn, will make it possible to significantly simplify the decision-making process. The indicated criteria can form the basis for choosing the most favorable stormwater management system for both large urban catchments and individual facilities. Thanks to the considerable flexibility of the developed decision problem structure, its widespread application can contribute to improving the efficiency of stormwater management systems. An example of the developed model’s application in a decision-making process is presented, concerning the selection of a design variant of a single-family residential building’s stormwater management system in Poland. Four design variants were included in the analysis, and the Analytic Hierarchy Process was used as the tool to select the most favorable option. This study shows that nature-based solutions are the most beneficial decision stormwater management options.

“…Rainwater Harvesting (RWH) is considered to be a solution to overcome water scarcity in coastal areas. Akter and Ahmed [4] studied the potential of RWH in the urban community of Agrabad Chittagong, Bangladesh. Their study revealed that the RWH allows rainwater to increase clean water by 20 liters/person/day throughout the year.…”

Muara Angke Fisheries Settlement Area, North Jakarta is a region that potential to experience water scarcity caused by limited water piped network and accompanied by poor groundwater quality due to seawater intrusion. In this situation, rainwater can be an alternative water source to meet household water needs. However, the implementation of Rainwater Harvesting (RWH) in hamlets 22, Muara Angke has not been a priority. Hence, this study aims to assess the acceptance of residents on RWH, their willingness to participate in implementing RWH, and the challenges of installing and maintaining RWH. The study uses the Multi-Dimensional Scaling (MDS) method with social, economic, and environmental aspects. The social aspect consists of 3 indicators: social capital, education, and government support. The economic aspect consists of 3 indicators: income, maintenance cost, and saving. The environmental aspect consists of 3 indicators: the quality, the quantity, and the continuity of rainwater. Data collection in this study involved 93 questionnaires which distributed after socialization of the RWH program and its benefit to the residents. This study analyzes the local people acceptance after socialization the RWH program and benefit to the residents. Results showed that education, social capital, government support, income, maintenance costs, saving, and 3 aspects of rainwater were statistically significant in explaining local resident acceptance of RWH in the study area. The people acceptance of RWH after socialization was change compared to before the socialization.
