“…Promoting water-saving devices is another high impact option but does typically require some rebates or investments in infrastructure [97]. For example, rainwater tanks may help reduce water demand by up to 80%, based on studies in the Australian context, and which in the Indonesian context can provide 100% volumetric reliability in the right circumstances [98], and studies in Bangladesh indicate that 30-40% reliability can be achieved in their context [99]. However, rainwater harvesting comes at a significant investment cost, and requires ongoing maintenance and operation by households [100][101][102].…”

This paper reports on a review of international water conservation efforts, but with a particular focus on the Australian context. The aim is to take stock of the current understanding of water conservation, in particular: what influences people's decision to conserve water, what influences whether people persist with water conservation behavior and what contributes to awareness and familiarity of water conservation behaviors. We also explore how all these factors jointly can achieve water savings over time, and the efficacy of past efforts to save water. Subsequently, this is used to identify where leading practice for managing water conservation is heading, which we argue is the application of recent developments in behavioral science and advances in smart metering to personalize water conservation programs. To support individualized water conservation efforts, we need more longitudinal studies of water conservation behavior, a greater focus on behavioral science, as well as the development of modelling tools that embed insights and lessons of this research into decision support capability. This can help to develop the capacity to better implement water conservation programs that respond to short-term water scarcity crises, such as droughts, while also providing persistent reductions in per-capita water demand that can help meet strategic water planning needs, such as deferring or downsizing capital investment in supply infrastructure to accommodate demands associated with population growth.

“…Another obstacle is that people believe that rainwater quality is worse than that of other water sources [38]. In addition, many people believe that installing a rainwater harvesting system is expensive and, thereby, unaffordable [40].…”

Fulfilling the need for clean water and proper sanitation is, globally, a basic human requirement, and Indonesia is no exception. Clean water and adequate sanitation are the sixth goal of the Sustainable Development Goals (SDGs), and targets include to ensure the availability of clean water and sustainable sanitation for all by 2030. The achievement of targets in water supply and sanitation in Indonesia is still lagging behind other fields. There are differences in the ease of obtaining access to clean water sources in urban and rural areas, especially for rural communities living on peatlands who experience issues in being provided with clean water. The difficulty is that, even though the amount of available water is relatively large, its quality is low. Barriers to the equitable distribution of services by the government to the entire community are caused by the limited availability of funding, the geographical conditions of scattered settlements, and the limited capacity of human resources. As a result of this problem, it is necessary to formulate a management strategy for providing access to clean water and sanitation for rural communities on peatlands. This research uses the case-study method. The management strategy was formulated on the basis of the environmental and socioeconomic conditions of the community. This method was used to test the effectiveness of the formulated strategy in realizing water security on peatlands in the village of Wajok Hilir. The resulting management strategy can be applied to other villages that have the same land characteristics. The strategy to realize water security for rural communities on peatlands is a self-service strategy. The implementation of the self-service strategy needs to be supported by infrastructure in the form of peat water treatment plant buildings, wells drilled to aquifer depths, and canal blocking to control the groundwater level in peatlands. The management strategy is carried out with community participation, considering that peatlands are a potential water source to meet clean water needs and achieve sustainable water security targets. Efforts to implement the self-service strategy are carried out with these methods: (1) socialization carried out in an integrated manner, (2) infrastructure development as a pilot project, (3) providing knowledge about infrastructure operations, (4) providing temporary assistance to the community, and (5) providing material supplies so that rural communities that are partners can become pioneers of similar movements.

“…The scenarios are based on the number of occupants, catchment area, and storage tank capacity as seen in Table 1. Alteration in catchment area and storage tank capacity will influence the RWH system performance [16]. The RWH system performance for each simulation was then compared to identify the influence of the rainfall data duration and time period.…”

Abstract.One of the attempts to tackle the problem in water resources is to exploit the potential of rainwater volume with rainwater harvesting (RWH) system. A number of rainfall data required for analyzing the RWH system performance. In contrast, the availability of rainfall data is occasionally difficult to obtain. The main objective of this study is to investigate the effect of difference rainfall data duration and time period to assess the RWH system performance. An analysis was conducted on the rainfall data based on rainfall data duration and time period. The analysis was performed considering 15, 5, 3, 2 years, average year, wet year, and dry year for Palembang city in South Sumatera. The RWH system performance is calculated based on the concept of yield before spillage algorithm. A number of scenarios were conducted by varying the tank capacity, roof area, and the rainwater demand. It was observed that the use of data with a smaller duration provides a significant difference, especially for high rainwater demand. In addition, the use of daily rainfall data would describe the behavior of the system more thoroughly. As for time step, the use of monthly rainfall data is only sufficient for low rainwater demand and bigger tank capacity.
