Implementation and characterization of a system for harvesting and using rainwater.

Abstract

This work relates to the implementation of a rainwater catchment system and its use. To determine rainwater quality, microbiological and physical-chemical analyses based on Mexican standards were conducted. The microbiological results showed various types of bacteria, such as bacilli, cocci and coliforms, among them Escherichia coli and Enterobacter aerogenes, while the physico-chemical results showed low TSS (8.9 mg/L), BOD (2.7 mg/L), COD (6.7 mg/L) and TOC (1.9 mg/L) concentrations. Moreover, a catchment system, with a treatment train supplying water with an adequate quality for the current needs, is proposed.
