A Case Study on Rainwater Harvesting and Reuse in Jordan

Abstract

The problem of continuous decline in precipitation in the Arab countries and neighboring countries is one of the most important challenges facing countries and societies in this region. The increasing shortage of rainfall due to climate change in these regions in particular and in most countries in the world in general drives these countries and communities to over-extraction from groundwater, which could result in rapid loss, The concept of water harvesting is intended to try to make the most of rainfall by finding ways to ensure the accumulation of the largest possible rain precipitation and to store it for use in many areas and in some extent to reduce the groundwater ,The aim of this study is to develop some methods in urban treatments through the design of sidewalks and streets within the cities in order to allow the flow of rainwater and work to collect them in containers used later in the irrigation of gardens or in the requirements of fire extinguishing systems or any other urban needs. This case study was done in Al Madina Al Munawwarah Street in Amman, Jordan. The results said that the total amount of water can be collected during the rain seasons in the target area will be about 9146 m 3 /y. This quantity can be used for a fire extinguisher or irrigation of plant or trees in the middle or at both sides of the street. This means that the water harvested over the Jordan area is about 243000000 m 3 .

Efficiency Rainwater Harvesting at the Roof Campus Buildings

“…pipe and funneled into a reservoir made under the road. The planned design must have a slope on the asphalt road body so that it can drain and collect rainwater [9].…”

Improvement of the Physical and Mechanical Properties of Natural Asphalt Mixes Using Petroleum Bitumen and Polyethylene

“…One of the best important methods that leads to a decrease in landfills zone, it is the addition of West plastic to asphalt mixtures [22], [23], [24]. In recent times, new expertise have been implemented to produce innovative sources take out the recycling of some consumable materials to decrease the adverse effects of the accumulated waste plastic and decrease the necessity for natural materials [25], [26], [27].…”

Design Restaurant Information System (RIS) Cloud Based with the Zachman Framework Approach

“…This storage system has benefits in two ways, namely increasing service flexibility and easy access to information [7]. In accordance with the EA stated earlier, this cloud system will use an infrastructure-as-a-service approach to integrate data from the EA that will be raised and the data is stored in a private cloud [8].There is research that has succeeded in making application design start with structure and how to navigate due to lack of content in the entire structure of cloud-based applications [9].In addition, there is also research into cloud computing applications, namely Open Stack application is a leading open source software to provide infrastructure as a service to users. It needs to investigate the security adequacy built into Open stack as OPEN STACK is intended to be used by many users [10].…”
