“…One plausible explanation is that implementation strategies are difficult to evaluate and may coexist as a support to evidence-based interventions, making them an undesirable subject to address [11,12]. In conjunction to this, there is an absence of research evaluating RWH implementation strategies, despite previous research [13][14][15] revealed that they are poor. This indicates that research into fidelity by focusing on strategies is critical in RWH implementation.…”

Rainwater harvesting has long been introduced as a green approach, followed by numerous established guidelines and policies to encourage its implementation. Policy implementation can be explored by assessing fidelity by utilizing a consensus reporting format and model/ framework. This paper exhibits a systematic review of the literature to synthesize the available knowledge on frameworks ideal for assessing implementation fidelity. PRISMA and forward snowballing technique were used to conduct an advanced search on the Web of Science and Scopus databases. Content analysis was performed primarily to identify the focal area, research questions and methods employed by previous studies that complement the StaRI reporting standard. The findings indicate that there is a scarcity of implementation strategies studies, not only in the built environment field, but also in implementation studies in general. While there are 28 implementation research frameworks/ models that have been used together with StaRi reporting guidelines, only two evaluation frameworks are found to be appropriate to the scope of the current study. The findings provide a basis of knowledge for determining the best framework for assessing fidelity in rainwater harvesting implementation.

“…The scavenging of air contaminants influences both the chemical composition and the pH of rainwater [9]. Acid precipitation is mostly caused by the anthropogenic sources such as sulfur oxides, and nitrogen oxides [6,10]. However, the acidity of rainwater depends on the relative contribution and neutralization of the major acidic and alkaline ions in atmosphere [3].…”

“…Historically, rainwater harvesting has been practiced traditionally in many dry regions in the world as early as 4,500 B.C [10,11]. Currently, rainwater harvesting has been practiced in many countries for reducing reliance on the availability of domestic water from dams and reservoirs [12], supply non-potable water to building in urban areas [13], and solving water issues in semiarid regions for agricultural and domestic uses [14].…”

As part of the implementation of a rainwater harvesting system as an alternative water source supply for nonpotable use, therefore the characteristic of chemical compounds was significantly explored. The Department of Chemistry, Malaysia, gave the data set for three years (2017-2019). Some chemometric techniques, including PCA, were performed to identify the dimensionality of the rainwater data, hence establishing the rainfall index's purity to determine the quality of rainwater in the study area. Discriminant analysis managed to differentiate each rain gauge station. Cluster analysis was then applied to perform smaller group of rain gauge stations. The result demonstrates that sea salt, secondary aerosols, trace metals, crustal origin, and organic acid dominated the dimensionality of rainwater data with a total variance of 53.38% and indicated that the PRI was significantly diversified into good purity of rainfall index (GPRI), (Labuan and Danum Valley), moderate purity of rainfall index (MPRI), (Kuching and Tawau) and bad purity of rainfall index (BPRI), (Kota Kinabalu and Bintulu). From the study, it can be stipulated that the chemical composition of rainwater in the study area was attributable to the local activities.

“…The impacts of climate change are difficult to predict, but regular floods and droughts and the associated shortages of available water resources may cause problems in the water supply system. Therefore, the development of alternative water sources, such as rainwater, reclaimed water, groundwater, and seawater desalination, has been researched as methods to prevent water shortages [4][5][6][7].…”

Using reclaimed water has been increasing to manage water shortages arising due to climate change. Research has been conducted on reclaimed water production, but few studies have investigated the pipe network and supply of reclaimed water. Reclaimed water contains greater amounts of organic matter, nutrients, and ionic substances compared to tap water. Therefore, it is highly likely to cause problems, such as water pollution due to microbial propagation in pipes, and leakage due to pipe corrosion, which interfere with water supply system operations. This study investigated the residual chlorine decay characteristics of chlorine disinfectants applied to a control biofilm in reclaimed water pipe networks. The bulk decay coefficient was compared between reclaimed water and a humic acid solution, and the origin of organic matter was analyzed using fluorescence excitation-emission matrices. The experimental results show that residual chlorine was consumed because protein and amino acid-based organic matter reacted more rapidly with chlorine than natural organic matter, such as humic acid. Moreover, chlorine bulk decay occurred rapidly in reclaimed water when total organic carbon was 3 mg/L or higher. These results confirm that removing organic matter during reclaimed water treatment may affect the management of the pipe network system.
