El objetivo de la presente invención es resolver los inconvenientes mencionados, proponiendo una instalación relativamente económica y que tenga costes de mantenimiento reducidos, y que al mismo tiempo permita un mayor aprovechamiento del terreno.The objective of the present invention is to solve  the mentioned inconveniences, proposing an installation relatively inexpensive and has maintenance costs reduced, and at the same time allow greater use of the land

De acuerdo con este objetivo, la instalación para la depuración de aguas residuales por infiltración-percolación de la presente invención se caracteriza por el hecho de que en la citada excavación se dispone además al menos una capa de material de recubrimiento, situada por encima de la capa de arena filtrante, comprendiendo el sistema de suministro del agua residual unas conducciones subterráneas dotadas de orificios y situadas en las proximidades de la zona de contacto entre la capa de material de recubrimiento y la capa de arena.In accordance with this objective, the installation for sewage treatment by infiltration-percolation of the present invention is characterized by the fact that the aforementioned excavation has in addition at least one layer of coating material, located by above the layer of filter sand, comprising the system of supply of wastewater with underground pipes equipped of holes and located in the vicinity of the contact area between the layer of coating material and the layer of sand.

Gracias al sistema de suministro y reparto de agua subterráneo y a la capa de material de recubrimiento, todo el sistema de tuberías y las capas filtrantes quedan totalmente enterrados, y el terreno ocupado por la instalación puede aprovecharse al mismo tiempo para otros usos, como por ejemplo para un jardín, una plaza pública, un campo de golf o similares.Thanks to the delivery and distribution system of groundwater and to the coating material layer, all the pipe system and filter layers are completely buried, and the land occupied by the facility can take advantage of other uses at the same time, such as for a garden, a public square, a golf course or the like.

El sistema es particularmente adecuado para lugares en los que las aguas depuradas se utilizan para el riego, como pueden ser los usos mencionados, aunque también podría aplicarse en los casos en que el agua depurada no se utiliza en el mismo lugar de la instalación, o se canaliza para su retorno controlado al acuífero.The system is particularly suitable for places where purified water is used for irrigation, such as the mentioned uses, although it could also apply in cases where purified water is not used in the same place of installation, or is channeled for return Controlled to the aquifer.

La instalación además es muy económica, puesto que tanto las conducciones como la capa de recubrimiento se depositan sin dificultad una vez depositadas las capas del filtro, no requiere componentes costosos o sofisticados, y tiene un mantenimiento mínimo.The installation is also very economical, since that both the pipes and the coating layer are deposit without difficulty once deposited the layers of the filter, It does not require expensive or sophisticated components, and has a minimum maintenance

Preferiblemente, dichas conducciones subterráneas consisten en tubos de material plástico. Por ejemplo, las conducciones pueden ser del tipo convencionalmente aplicado en algunos tipos de riego.Preferably, said pipes Underground consist of plastic pipes. For example, the pipes can be of the conventionally applied type in Some types of irrigation.

En una realización de la invención, las conducciones presentan orificios exclusivamente en su parte inferior.In an embodiment of the invention, the pipes have holes exclusively in their part lower.

En una realización, dicha capa de material de recubrimiento es de tierra; alternativamente, la capa de material de recubrimiento puede ser de arena o puede incluir una capa de hormigón, cemento, piedra o materiales similares; la selección de los materiales de recubrimiento dependerá del uso al que se quiera destinar el terreno.In one embodiment, said layer of material of coating is ground; alternatively, the material layer Coating can be sand or can include a layer of concrete, cement, stone or similar materials; the selection of Coating materials will depend on the intended use set aside the land

La instalación descrita puede incorporar además todos los elementos propios de instalaciones de depuración por infiltración-percolación clásicas, como pueden ser capas de impermeabilización de la excavación para evitar la contaminación de los acuíferos, distintos tipos de tuberías de drenaje, etc.The described installation may also incorporate all elements of debugging facilities by classic infiltration-percolation, such as waterproofing layers of the excavation to avoid pollution of aquifers, different types of pipes drainage, etc.

Breve descripción de los dibujosBrief description of the drawings

Con el fin de facilitar la descripción de cuanto se ha expuesto anteriormente se adjuntan unos dibujos en los que, esquemáticamente y tan sólo a título de ejemplo no limitativo, se representa un caso práctico de realización de la instalación de la invención, en el cual:In order to facilitate the description of how much  It has been exposed above are attached some drawings in which, schematically and only by way of non-limiting example, It represents a case study of the installation of the invention, in which:
