Resumen
La Construcción Sostenible últimamente ha ido aumentando su revuelo y cada vez
más se está implementando en Chile, además de realizarse estudios más acabados.
Su importancia cada vez va a tomar mayor relevancia en lo que al calentamiento
global se trata.
La presente investigación se refiere a un sistema que ha sido especialmente
concebido para la reutilización de determinadas aguas residuales domésticas, tales
como las generadas en bañeras, lavadoras, lavavajillas y otras.
El objeto de este sistema es reducir el consumo de agua limpia sanitaria, mediante
la reutilización de las aguas residuales anteriormente citadas, concretamente como
agua de descarga en los inodoros como también para riego.
Como es sabido, en cualquier vivienda una parte muy importante del consumo de
agua sanitaria es el que se produce en lavamanos y duchas, donde se genera un
agua residual con un grado de suciedad mínimo y cuya contaminación
prácticamente no va más allá que la de los detergentes utilizados en el aseo
personal.
Otras aguas grises tales como las generadas por lavadoras, lavavajillas, lavaplatos,
presentan un grado de suciedad más alto que las anteriores y su consumo también
es muy importante.
El sistema para la reutilización de aguas grises domésticas que la de éste trabajo
propone tiene como finalidad específica precisamente el aprovechamiento de las
aguas producidas en bañeras, lavadoras, reutilizándolas como medio de
alimentación fundamental para los inodoros de una vivienda colectiva, con acceso
directo a dichos inodoros, es decir sin pasar a través de la cisterna de los mismos, y
manteniéndose dicha cisterna conectada como es convencional a la red de
suministro de agua sanitaria, para su utilización esporádica a criterio del usuario.
Para ello y de forma más concreta, el sistema se basa en la utilización de un
depósito colector, situado por ejemplo en los sótanos del edificio, que recibe las
aguas grises de las diferentes viviendas, obviamente con excepción de las
generadas por los inodoros, a través de una bajada comunitaria provista de una
válvula y un filtro que impide la llegada de impurezas sólidas al citado depósito. A su
vez el depósito está conectado con los diferentes inodoros de las distintas viviendas,
a los que suministra el agua jabonosa filtrada preferentemente con la colaboración
de una bomba de presión, la cual abastece el agua ya tratada los WC o el riego de
jardines, eliminando prácticamente el consumo de agua potable para estos servicios.
Property development has increased ostensibly in Chile, creating the need for related advanced studies, particularly due to the impact of new estates on global warming. The present research refers to a system that has been specially designed in order to reuse sewage water generated from baths, washing machines, dishwashers, or irrigation water, and thus reduces the consumption of clean sanitary water. The greatest water consumption areas in any home are the sink and the shower. In the latter case, the residual water produced is contaminated only by the cleansing agent used for cleaning our bodies. Other grey waters such as those generated from washing machines, dishwashers and sinks have a higher content of dirt than the previous ones and their consumption is also significant. This paper proposes a system for reusing sewage water. It aims at taking advantage of the waters produced in the shower, washing machines, and others, by reusing them to flash the toilets in a house, to which they would be directly connected. This means that the water does not pass through the cistern, which is conventionally connected to the network of water supply for the consumers' daily consumption. In this particular case, the system consists of a sewer that receives grey waters from different houses, and can be located in the basement of a building, for example. Obviously, this excludes the waters generated from toilets. A communal descent provided with a valve and a filter prevents solid impurities from reaching the sewer. The sewer is connected to toilets from different houses, and supplies soapy filtered water, preferably with the help of a pressure pump. The system thus supplies already treated water to toilets and gardens, eliminating the use of drinkable water for these purposes.
