“…The mean pH value of the harvested runoff samples are within the WHO drinking water standard range of 6.5 to 8.5 which could be used for domestic purposes. Similar studies have reported an increase in pH value from ambient rainwater to harvested roof runoff water [7,32,33].…”

Samples collected from different runoffs; AR, GMR, TR, ASR, and DR for aluminum roof, galvanized metal roof, thatch roof, asbestos roof and ambient rainfall respectively were analyzed for pH, conductivity, turbidity, TDS, TSS, NO3-, PO43-, Cd, Cu, Fe, Zn and Pb. The result indicates that the mean concentration of the parameters analyzed ranged from 5.8± 0.39 –7.10±0.70, 22.25±11.70-79.99± 3.40μScm-1, 1.47±0.43 - 46.53±1.60mg/l, 11.90±0.93 - 59.83±1.62NTU,15.53±0.70 - 204.53±5.08mg/l, 0.93±0.06 - 2.55±0.13 mg/l, 1.33±0.22 - 7.30±0.57mg/l respectively for pH, conductivity, TDS, turbidity, TSS, PO43-and NO3-, and the levels of the heavy metals (in mg/l); Cd, Cu, Fe, Zn and Pb ranged from 0.0023±0.001– 0.0521±0.004, 0.052±0.01–0.2483±0.02, 0.0348±0.01–1.1120±0.07, 0.0161±0.01-0.8093±0.02 and 0.0106±0.01-0.0499±0.002 respectively. Ranking of the heavy metal in roof runoff is in the order; Fe>Zn>Cu>Cd>Pb. The result compared with WHO standard showed elevated level of the parameters analyzed with Cd and Pb exceeding the limit. Though the result of this study showed some variability which is an indication of the type of roofing material; air quality of the environment and industrial activity going on in the area. It could be deduced from the result that roof runoff may be a non point source of environmental pollution owning to the release of heavy metals and other pollutants into the environment, and increased concentration of some of the pollutants as reported by this study suggests that roof runoff water could impact negatively to the environment and if consumed without being treated may be injurious to human health.

“…Roofs are the first candidates for RWH systems because their runoff is often regarded as unpolluted (Förster, 1999). However, some studies have reported that there is a potential for rainwater to carry nutrient pollution (total phosphorus and nitrate nitrogen) (Vijayaraghavan et al, 2012), microbial pathogens (Ahmed et al, 2008;Simmons et al, 2001), heavy metals (Lee et al, 2010;Wang and Li, 2009) and pesticides (Zobrist et al, 2000). Therefore, it is essential to investigate the water quality of roof runoff for domestic use.…”

“…The quality of harvested rainwater has also been found to be dependent both on the roof type and environmental conditions (local climate and the level of atmospheric pollution) (Lee et al, 2010). Chang et al (2004) compared harvested rainwater quality from four roof types (wood shingle, composition shingle, painted aluminum, and galvanized iron) at Nacogdoches, Texas.…”

a b s t r a c tThere is an urgent requirement to examine the quality of harvested rainwater for potable and nonpotable purposes, based on the type of roofing material. In this study, we examined the effect on the quality of harvested rainwater of conventional roofing materials (concrete, asphalt and ceramic tile roofs) compared with alternative roofing materials (green roof). The results showed that the ceramic tile roof was the most suitable for rainwater-harvesting applications because of the lower concentrations of leachable pollutants. However, in this study, the green roof was not suitable for rainwater harvesting applications. In addition, seasonal trends in water quality parameters showed that pollutants in roof runoff in summer and autumn were lower than those in winter and spring. This study revealed that the quality of harvested rainwater was significantly affected by the roofing material; therefore, local government and urban planners should develop stricter testing programs and produce more weathering resistant roofing materials to allow the harvesting of rainwater for domestic and public uses.

É preciso observar o tipo de telhado e condições ambientais, pois interfere na qualidade da água recolhida [22].…”

Water is essential for human survival and also for the entire ecosystem of the planet. The lack of this precious asset will cause irreversible damage to the planet. Many countries are having various problems with the scarcity of drinking water. Some regions of Brazil are facing a water crisis of its natural resource. As an example the city of São Paulo, which recently presented a historic decrease in its reservoirs. Humanity must be aware of the importance of water and its waste. This new culture must be taken immediately, through sustainable renovation of actions to ensure the maintenance and regeneration under appropriate conditions for future generations. The objective of this article is to enable a rainwater collection system, easy to handle, practical for installation, occupying little space and economically viable for the final consumer. The materials presented in a major way was polyvinyl choride (PVC), it is a lightweight material, easy to handle, has a high durability relevant to other materials such as metal pipes and is not reagente to no other kind of material, keeping integrates water quality, without changing it. The methods applied were the steps to progress the proposed project identifying the six steps whose implementation procedures in accordance with current regulations. The expected results are presented as a contribution proposed for sanitation and environmental management, in order to enable solutions that promote the use of rainwater for non-potable purposes with storage vertical tanks for the cities that have monthly precipitation in min (60 mm).Keywords: Rainwater, use, water resources, vertical tank Proposta de projeto de aproveitamento de águas pluviais para fins não potáveis em cisterna vertical RESUMO A água é fundamental para a sobrevivência humana e também para todo o ecossistema do planeta. A falta desse bem tão precioso acarretará prejuízos irreversíveis ao planeta. Muitos países estão tendo diversos problemas com a escassez de água potável. Algumas regiões do Brasil estão enfrentando uma crise hídrica do seu recurso natural, exemplo disso foi à cidade de São Paulo, que recentemente apresentou uma baixa histórica em seus reservatórios. A humanidade precisa se conscientizar da importância da água e do seu desperdício. Essa nova cultura, deve ser tomada de imediato, através de ações de renovação sustentável que garanta a manutenção e regeneração em condições adequadas para as futuras gerações. O objetivo do artigo é viabilizar um sistema de captação de água pluvial, de fácil manuseio, prático na sua instalação, ocupando pouco espaço e viável economicamente para o consumidor final. O material apresentado de forma principal foi o policloreto de polivinila (PVC), pois é um material leve, de fácil manejo, possui uma alta durabilidade pertinente aos outros materiais, como os tubos metálicos e não é reagente a nenhum outro material da natureza, mantendo integra a qualidade da água, sem alterá-la. Os métodos aplicados foram às etapas para evolução do projeto proposto identificando...
