“…This operation recharges the aquifer and enhances the productivity of wells and springs. The advantages of infiltration wells as summarized by Szabó et al [117] include (i) faster increase of groundwater level, (ii) lower evaporation loss, (ii) lower risk of biological activity, and (iv) smaller surface area use. However, infiltrated water should be of adequate water quality in order to avoid groundwater contamination [116][117][118].…”

“…They are actually not used because either they have dried out, or because the water table was not reached and the well project was abandoned. Using these wells for infiltration is advantageous for water management, as recently demonstrated in Hungary [117]. Such wells can be filled with gravel and/or sand to eliminate the risk that vagabonding animals fall and die in water.…”

The whole population of Feutap still collects drinking water from two protected springs, some 1 km away from this small rural agglomeration. For many generations, the only improvement has been the protection of the springs during the 1980s. The resulting high incidence of gastrointestinal infections continues to hinder the socioeconomic development of this mountain community. This dynamic wherein “poverty begets disease, and disease begets poverty” seems endless given the number of water improvement programs and other health-focused campaigns in rural areas of Cameroon since the 1960s. Fortunately, the hydrographic regime of Feutap and its geographical situation enable the implementation of the Kilimanjaro Concept (KC), wherein rainwater is quantitatively harvested, partly infiltrated, and largely stored to (i) meet the whole-year water needs of the population, (ii) create new ecosystems, and (iii) enable irrigated agriculture. This communication prepares the implementation of the KC in Feutap, including the creation of irrigation ponds for agriculture and small farm animals (e.g., goats and sheep). The view is promoted that Feutap is a potential viable space in which life and work are possible, using the existing rainfall and the few natural springs in a sustainable manner. The presented concept can be extended to other hilly small communities with similar hydraulic regimes.

Jagakarsa is one of the districts in South Jakarta that has a rainwater catchment area. Problems arise as a result of the high rate of population growth, which has an impact on changes in land use and increased surface runoff, causing flooding. On the other hand, the absence of clean water provision facilities from the government means that people use groundwater-drilled wells to meet their daily clean water needs. Sustainable groundwater consumption has an impact on land subsidence and vulnerability to groundwater availability. Therefore, it is necessary to carry out research. This research seeks to assess the potential for rainwater harvesting based on field observations. The research was carried out by analyzing rainfall data, field surveys, research program socialization, and community socio-economic analysis. Rainfall is high, with an annual average of 2809.7 m. 98% of respondents use drilled groundwater wells with a wells depth in the deep aquifer layer, and public interest in rainwater harvesting (RWH) technology is high. These show the potential for implementing RWH in the study location. This research is an initial study; for the integrated implementation of RWH, further research is needed after this study.

“…Rainwater harvesting is widely acknowledged as a simple, inexpensive and sustainable worldwide solution to fight the freshwater crisis [10][11][12]. It is among the oldest solutions to save water in dry regions [13] and after decades of abandonment, it is regaining momentum among researchers [14][15][16][17][18]. Rainwater harvesting refers to the collection of rainwater during periods of abundance (wet periods), to be reused later, when water is scarce (dry periods).…”

“…In the Balearic Islands, aljibe-like storage systems are now mandatory for all new private buildings [19]. The collection and storage of rooftop rainwater is possibly the most popular harvesting technique [18,20,21], but the limited areal surface of private houses' rooftops is typically not sufficient to generate sufficient volumes to balance out the water consumptions of these properties.…”

Mediterranean islands suffer from a lack of freshwater due to persistent and recursive droughts, limited groundwater availability and mass tourism. In Ibiza (Spain), private estates disconnected from the water distribution network consume about 21% of the total freshwater demand on the island. We conducted a study to evaluate the potential of ground-runoff harvesting (GRH) as a sustainable and inexpensive solution to increase freshwater availability in isolated households in Ibiza. The study involved an innovative modular tank of 40 m3 buried in the garden of a private property. The tank intercepted runoff forming in a 12,300 m2 hilly micro-catchment. We found that an extreme rainfall event with an intensity of 65 mm/h was able to create sufficient runoff to fill up the tank in one hour. A curve-number-based rainfall-runoff model was used to simulate the experimental results and to obtain a first-cut estimation of the potential of GRH at the scale of the island. The analysis indicates that, if installed in all forest areas in Ibiza with a similar slope to the study area, a volume of 1.31×106 m3 of freshwater could be harvested per year on the island just from extreme precipitation events. Such a volume of water is equivalent to about 5% of the island’s total freshwater budget. The study concludes that GRH is a highly valuable, yet still unexploited opportunity to save large freshwater volumes in dry-climate areas like Ibiza. GRH should be promoted across Mediterranean islands, and it can be easily incorporated within local water regulations.
