Perkembangan penduduk di kota Batam mengakibatkan peningkatan frekuensi terjadinya banjir yang terjadi terutama di Perumahan Citra Indah, Batam Center.  Untuk mengatasi masalah yang timbul akibat peningkatan frekuensi terjadinya banjir, maka dilakukan analisis penerapan sistem rainwater tank pada kawasan perumahan. Penelitian ini bertujuan untuk mengetahui perencanaan raintwater tank dan mengetahui jumlah air dan biaya yang dihemat dengan sistem rainwater tank untuk kawasan perumahan Citra Indah, Batam Center. Penelitian ini menganalisis kebutuhan tanki yang diperlukan untuk 4 tipe rumah di perumahan Citra Indah. Data perumahan diperoleh dari PT Bangun Arsikon Batindo dan data curah hujan dari Badan Meteorologi, Klimatologi dan Geofisika (BMKG) Kota Batam. Metode perhitungan dengan menggunakan curah hujan andalan 80% berdasarkan curah hujan tahun 2010-2019 dan luas atap rumah sebagai luas penangkapan. Hasil analisa penerapan sistem rainwater tank di perumahan Citra Indah, untuk tipe rumah 120/162 membutuhkan tanki dengan volume 10,45 m3, tipe rumah 103/120 membutuhkan tanki dengan volume 9,72 m3, tipe rumah 78/105 membutuhkan tanki dengan volume 9,00 m3 dan tipe rumah 50/90 membutuhkan tanki dengan volume 8,79 m3. Penerapan sistem tersebut dapat menghemat penggunaan air sebesar 7,344 m3/bulan dan Rp 705.024/tahun.

Despite numerous studies on residential rainwater tank, studies on commercial rainwater tank are scarce. Corporate authorities pay little heed on this sustainable feature. With the aim of encouraging corporate authorities, this study presents the feasibility and economic benefits of rainwater harvesting (RWH) in commercial buildings in the capital city of Bangladesh, where water authority struggles to maintain town water supply. The analysis was conducted using a daily water balance model under three climate scenarios (wet, dry and normal year) for five commercial buildings having catchment areas varying from 315 to 776 m2 and the storage tank capacity varying from 100 to 600 m3. It was found that for a water demand of 30 L per capita per day (lpcd), about 11% to 19% and 16% to 26.80% of the annual water demand can be supplemented by rainwater harvesting under the normal year and wet year climate conditions, respectively. The payback periods are found to be very short, only 2.25 to 3.75 years and benefit–cost (B/C) ratios are more than 1.0, even for building having the smallest catchment area (i.e., 315 m2) and no significant overflow would occur during monsoon, which leads to both economic and environmental benefits. Though the findings cannot be translated to other cities as those are dependent on factors like water price, interest rate, rainfall amount and pattern, however other cities having significant rainfall amounts should conduct similar studies to expedite implementations of widescale rainwater harvesting.

In early 2003, after a prolonged drought period, extensive bushfires occurred in the east of Victoria affecting 1.5 million hectares of land. At the time, smoke and ash from bushfires, settling on roofs, contained pollutants that could potentially contaminate rainwater collected and stored in tanks for domestic use. The major concerns include polycyclic aromatic hydrocarbons (PAHs) from incomplete combustion of organic matter and arsenic from burnt copper chrome arsenate (CCA) treated wood. An increase in microbial contamination through altered nutrient levels was also hypothesised. A pilot study of 49 rainwater tank owners was undertaken in north-east Victoria. A rainwater tank sample was taken and analysed for a variety of parameters including organic compounds, microbiological indicators, metals, nutrients and physico-chemical parameters. A survey was administered concurrently. A number of results were outside the Australian Drinking Water Guideline (ADWG) values for metals and microbiological indicator organisms, but not for any tested organic compounds. PAHs and arsenic are unlikely to be elevated in rainwater tanks as a result of bushfires, but cadmium may be of concern.

This article aims to present an economic feasibility and user satisfaction analysis of a rainwater harvesting system in a multi-storey residential building (where there is rainwater to supply toilets) located in Florianópolis, southern Brazil. This research used detailed methods and also considered the opinion and habits of users regarding the use of a rainwater harvesting system. The water end-uses were estimated through questionnaire survey in each flat. The potential for potable water savings was estimated using computer simulations. Simulations were performed using the computer programme Netuno, version 4 and economic feasibility analyses were performed considering different rainwater demands. Analyses associated with the habits of the residents, the satisfaction of users and the importance of saving potable water were also carried out. Showers were responsible for the highest share (54.2%) of water consumption in the flats, followed by the other end-uses: washing machine (21.3%), kitchen tap (9.3%), toilet flush (9.2%) and washbasins (2.6%). The most economically feasible system, which presented lower payback and higher internal rate of return, corresponds to the system sized to supply rainwater only to toilet flushing. Such a system would need a rainwater tank with a capacity smaller than the capacity of the one currently in use. In general, residents expressed satisfaction regarding the rainwater harvesting system installed in the building. The study is important because, besides obtaining water end-uses in the flats, it also investigates the perception of residents related to rainwater harvesting, which has been little explored in the scientific literature.
