“…Roebuck et al [59], however, found that RWH systems in the UK are not likely to present any payback period and concluded that any research that finds they can should be thoroughly examined. It appears that the majority of researchers have found that RWH systems are not financially viable [19,52,57,[59][60][61]. Conflicting results may be affected by a number of financial assumptions and modeling parameters, as discussed later.…”

Rainwater harvesting (RWH) plays an important role in increasing water security for individuals and governments. The demand for tools to enable technical and economic analysis of RWH systems has led to a substantial body of research in the recent past. This paper focuses on the economic aspects of domestic RWH in urban and peri-urban environments. In this regard, key issues are identified and discussed including quality and quantity of harvested water, the water demand profile, the scale of installation, interest rates, the period of analysis, real estate value, and the water-energy-food nexus. Kenya and Australia are used as reference points having different economies and opposing RWH policies. It has been found that the previous studies on financial aspects of RWH systems often had conflicting results. Most of the economic analyses have ignored the full benefits that a RWH system can offer. In view of the varying and conflicting results, there is a need to standardize the methods of economic analysis of RWH systems.

“…Ongoing maintenance expenses have often been identified as a primary reason for RWH system costs outweighing the benefits [59,60]. Hall [48] found that the variation in yield, along with pump and tank life and maintenance, had the largest effect on cost-effectiveness.…”

This work aimed to develop an optimization methodology for reservoir sizing in rainwater harvesting systems in order to increase the economic viability of projects in this area. For this, concepts of Operations Research were used so as to develop mathematical programming problems related to minimizing the life cycle cost and maximizing efficiency. The results obtained for different sizing methods were presented based on a case study, emphasizing the importance of tools that are able to provide a more accurate analysis and tend to significantly increase the economic viability of rainwater harvesting systems.

“…Households employ a wide variety of water storage infrastructure, including underground cisterns, rooftop storage tanks, large buckets, and assortments of small storage vessels, with capacities varying to deal with intermittency. ,,,, Although previous studies have shown storage to be ubiquitous in areas with IWS, its contribution to water access reliability is poorly understood. Water storage allows households to access multiple sources of water (e.g., water trucks, private or public wells or boreholes, bottled water, or rainwater). ,,, Water trucks deliver bulk volumes of water to residents’ homes, typically at a much higher cost than the municipal piped water, and are common in communities with IWS. ,− Rainwater harvesting has been posed as a potential solution to water scarcity in cities worldwide because of its benefits to households as a low cost water source, although the financial viability of sophisticated collection systems has been contested. − At the municipal level, rainwater harvesting has been promoted to delay costly expansions of centralized water systems and provide co-benefits of flood control and conservation. ,− …”

One billion people worldwide experience intermittent water supply (IWS), in which piped water is delivered for limited durations. Households with IWS must invest in water storage infrastructure and often rely on multiple sources of water; therefore, these household-level purchasing and infrastructure decisions is a critical component of water access. Informed by interviews with IWS households, we use radial basis function networks, a type of artificial neural network, to determine optimal household water management decisions that maximize reliability of water supply while minimizing costs for a representative household in Mexico City that uses municipal piped water, trucked water, and rainwater. We find that securing reliable water supply for IWS households is greatly assisted by installation of household storage tanks of at least 2500 L. In the case of IWS households with limited storage options, the overall cost for water supply is reduced by scheduling water deliveries on nonconsecutive days. Rainwater harvesting systems were shown to be economically viable for households with limited water supply. This study demonstrates the importance of considering the management of multiple sources and household storage infrastructure when evaluating water investments in cities with IWS.
