Technical Guidelines for Installation of Rainwater Harvesting System and its Operation

Abstract

Rainwater harvesting (RWH) systems have been in use since ancient times, and these days its use is increasing. However, due to improper planning and design, problems are seen and the collected water is polluted. The major reason for water contamination is attributed to the toxic materials used for the rain harvesting system, faulty operation, improper rain filtration system and improper disinfection methods. The reason for diseases arising from drinking rainwater is the consumption of contaminated rainwater. Clean raindrops comprising rainwater will become contaminated as they pass through the atmosphere, flow over the roof surface, flow along the gutter, and upon collection and storage. This paper focuses on the technical guidelines for the installation of RWH components, its operation and maintenance, and rainwater quality improvement for household use.
