Abstract: To address the growing need for water and energy in a sustainable and economical way, it is important to explore alternative, simpler technologies for conserving water and harnessing solar energy. Rainwater harvesting stands out as one of the most effective approaches to meet these needs. This project focuses on the technical side of rainwater collection from agricultural lands. Initially, necessary information such as catchment area sizes and rainfall data is gathered. Based on this, the water harvesting potential is calculated, and an appropriate tank design and capacity are determined.

The study also covers the design and analysis of gutters, as well as systems for first flush and filtration. A specially designed pot-shaped umbrella structure is proposed for installation in agricultural fields. This structure will not only help conserve space but it also allows for dual use: collecting rainwater and generating solar power. During the rainy season, water accumulates in the umbrella structure. Each unit is designed to hold a specific maximum volume of water, with any excess being directed to storage tanks for later use. Additionally, solar panels installed on the umbrella can significantly enhance solar energy generation. As part of the project, an estimation of runoff volumes in the agricultural area is conducted, along with an evaluation of current shortcomings, so that necessary improvements can be implemented.
