代写论文：雨水利用
雨水收集是一种有效的方法，用于在全球范围内利用雨水用于家庭和农业用水。这个过程已经用了几十年了。然而，技术进步帮助在社会发展项目中提供了便携式水。该技术在城市和半城市地区都有广泛的应用，因为在该地区对水的供应和水质的依赖程度较低。几十年来，雨水收集一直被用于确保家庭和农业用途的家庭住宅和农田的不间断供水(Ahmed, Masry, Saleh & Nada, 2013, p. 71)。在技术革新城市供水系统之前，雨水从建筑物的屋顶收集起来，储存在储水池中。然而，随着技术的出现，雨水作为家庭供水的主要来源而获得了实质。

Rain water harvesting is an effective method used for utilization of rain water for household and agricultural use across the globe. The process has been in use for decades now. However, technological advancement has helped in providing portable water in social development projects. The technique has wide application in both urban and semi-urban areas where there is less reliance on water supply and quality of water available in the region. For over decades, rain water harvesting has been used for ensuring uninterrupted water supply to domestic houses and farmlands for household and agricultural purposes (Ahmed, Masry, Saleh & Nada, 2013, p. 71). Before technology revolutionized city water systems, rain water was collected from building’s roof and stored in storage tanks. However, with the advent of technology, rain water gained essence as primary source of water supply in households.
