Development the quantity of drinking water in schools through rainwater collection in the western of sulaimany, for example.

Abstract

This study focuses on rainwater harvesting from a group of schools and institutes in Sulaymaniyah city. For this purpose, five centers were selected as samples in the research area. To analyze the possibilities and predict rainwater harvesting capacity, it is noteworthy that natural factors such as climate are among the most influential factors affecting the outcomes and predictions of rainwater harvesting. These factors include precipitation, temperature, wind, and evaporation. Data for these factors were collected in the research area over 22 years. Meanwhile, the central sample locations were mapped using GIS 10.8 software. Additionally, using Google Earth Pro and Garmin GPS72 technology, the area, elevation, and geographical location of the schools in the research area were calculated. 

On the other hand, the volume of rainwater harvesting and the determination of water storage requirements and capacity for usage were analyzed through relevant equations. 

Overall, the results of water harvesting in schools can be used as a primary water source or as a secondary source to meet the schools' water needs. Considering the low cost of implementation and the numerous benefits of this project, it is evident that some schools can fully rely on this source, while on average, it can meet 62% of the water demand for schools. 

Therefore, it is recommended that, given the noticeable climate changes and global warming, relevant authorities should consider establishing multiple projects of this kind with a detailed scientific plan to address water scarcity, reduce flood risks, and recharge groundwater.position, in the sense that the choice of research paradigm takes precedence.
