“…Appropriate temporary storage before subsequent infiltration is critical to avoid contamination of rainwater. The storage capacity does not only depend on direct uses in households nor on the irregularity of rainfall, but on the target amount of water to be harvested for immediate direct use and infiltration into groundwater systems for subsequent use during the dry season [28,30]. This approach would be an apparent attempt to realize an old vision of King Parakramabahu of Sri Lanka (12th century), who stated that, "Let no drop of water flow to the sea unused by man" [4].…”

“…In the East African Rift Valley and Kenya in particular, RWH is mainly used for drinking water and agricultural needs [23,38]. It has been recognized that RWH reduces stormwater runoff, decreases watershed pollution, and improves water management in an affordable manner [23,28,30,[38][39][40][41][42]. Harvested rainwater is currently utilized for: (i) drinking water supply, (ii) domestic non-potable uses such as toilet flushing and clothes washing, and (iii) landscape irrigation and agricultural crop irrigation [43,44].…”

“…Thus preliminary analysis and subsequent treatment using low-cost methods may need to be considered on a case-by-case basis. Recently, some studies have investigated the following: (i) surface treatments for enhancing rainwater harvesting [30], (ii) site selection for rainwater harvesting and subsequent storage systems [32], and (iii) the effects of climate change and variability on urban rainwater harvesting systems [33]. These recent studies provide critical information for the implementation of the Kilimanjaro Concept.…”

“…Locally infiltrating rainwater prevents salt intrusion in coastal areas, and deeper groundwater drawdown and depletion, which are the most widely reported adverse impacts of excessive groundwater abstraction [9,28,29]. Additionally, compared to surface runoff in rivers and streams, locally infiltrated rainwater is less likely to come in contact with agriculture and industry-related pollution, mainly where agricultural and industrial wastewaters are not treated before discharge into the environment [30][31][32][33].…”

Rainwater is conventionally perceived as an alternative drinking water source, mostly needed to meet water demand under particular circumstances, including under semi-arid conditions and on small islands. More recently, rainwater has been identified as a potential source of clean drinking water in cases where groundwater sources contain high concentrations of toxic geogenic contaminants. Specifically, this approach motivated the introduction of the Kilimanjaro Concept (KC) to supply fluoride-free water to the population of the East African Rift Valley (EARV). Clean harvested rainwater can either be used directly as a source of drinking water or blended with polluted natural water to meet drinking water guidelines. Current efforts towards the implementation of the KC in the EARV are demonstrating that harvesting rainwater is a potential universal solution to cover ever-increasing water demands while limiting adverse environmental impacts such as groundwater depletion and flooding. Indeed, all surface and subsurface water resources are replenished by precipitation (dew, hail, rain, and snow), with rainfall being the main source and major component of the hydrological cycle. Thus, rainwater harvesting systems entailing carefully harvesting, storing, and transporting rainwater are suitable solutions for water supply as long as rain falls on earth. Besides its direct use, rainwater can be infiltrating into the subsurface when and where it falls, thereby increasing aquifer recharge while minimizing soil erosion and limiting floods. The present paper presents an extension of the original KC by incorporating Chinese experience to demonstrate the universal applicability of the KC for water management, including the provision of clean water for decentralized communities.

“…Furthermore, as reported by [13], RWH could reduce "impacts on the environment and human health, stormwater runoff and combined sewer overflows, and economic viability". As observed by various authors, RWH represents a valid system to reduce stormwater runoff, improving water management in an affordable manner [14][15][16]. Surface runoff is a phenomenon that, at the farm level, is triggered by 10 to 25% of rainwater falling in arid and semi-arid areas, and it can have negative effects on soil erosion and the accumulation of nutrients, chemicals, and sediments into rivers and streams [5].…”

Increasing aridity and subsequent water scarcity are currently among the major problems of agriculture. Rainwater harvesting could represent a way to tackle this issue, and, as a consequence, scientific research has been more and more focused on such topic. On the other hand, few scientific studies related to economic and environmental assessment of rainwater harvesting systems in agriculture are available. The present study carried out an economic and environmental analysis of two different systems for rainwater harvesting: a typical pond and an innovative flexible water storage system (FWSS). The environmental and economic performance of the systems was compared using the Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) methodologies, referring to a functional unit (FU) of 1 m3 of storable water. The FWSS showed better environmental end economic performance than the pond system, resulting with both lower environmental impacts (17.04 g per m3 CO2vs 28.2 g per m3 CO2) and lower costs (16.94 € per m3vs 20.41 € per m3). Moreover, the pond system was more impactful than the FWSS for all the 17 categories investigated. Therefore, the FWSS can be a suitable solution for water harvesting in agriculture sector, showing interesting features for farmers.
