Aprovechamiento y reutilización de agua gris en los edificios del campus UTPL

Abstract

Abstract: The consumption of water in educational centers is high, gray water (AAGG) is a valuable resource that is not being used. The objective of this project is to develop a system for collecting AAGG from the sinks, for its reuse in recharging toilets, washing floors and watering gardens in the UTPL parking lot. The buildings defined for the collection were 3, 4, 7 and D, the average daily volume of AAGG that can be collected is 6.30 m³. The AAGG characterization showed that the level of contamination is low, the chosen treatment consists of: grease trap, filtration system and chlorine disinfection. Finally, the results obtained obtained that by implementing this system an efficient use of water is achieved and an annual saving of $ 3,241.06 in payroll.The cost of the project is $ 19,688.01, the economic feasibility analysis showed that the investment is recovered after 6.6 years and the cost / benefit ratio is 2.52, this indicates that the project is profitable and self-sustaining.
