The wastewater is characteristically be generated in a continuous manner. This means, that is a theoretical source of water and which has continued as time passes.

In some countries near the Mediterranean, Europe, and in many parts of Central and South America, from several centuries ago is implemented reuse, either directly or indirectly, of sewage. Uses can be for agricultural purposes (such as irrigation of crops in the vicinity of large cities) or as potable water after various discharges. Because of the known risks associated with these practices (including also the damages sensory and aesthetic), it encouraged the creation of sewage systems that were in charge of removing the residual water urban centers. Subsequently implemented the manufacture of treatment plants in those cases in which the company had the resources to assume this expense.

Somehow, in the beginning, the main objective of the purification was reducing the impact of discharges into receiving waters made, as well as health awareness of the potential hazard due to contact of the wastewater and people. Subsequently, in our recent history were taken into account other considerations, most water-related causes. The aim of the reorganization plan was reformulated, and given importance to the maintenance and good quality of the channels. Thus was achieved protect seaside tourism and also reduce costs of water purification.

Currently, shortages are the most afflict our societies. Therefore, we are beginning to set eyes on a resource within walking distance, very focused and quality was relatively unknown: the so named wastewater. It is proved that certain plants that are irrigated using waste water, grow in an excellent manner and have an attractive appearance that makes it possible sale with good benefits.

With this, the waters that lie beneath many cities, is converted for agricultural purposes, contributing to the growth of fruits and vegetables that are then sold in markets in those same cities. This practice is now in force, as in Mexico, in certain parts of Spain, and also in some African cities. Besides being a great way to recycle the water, is also the best choice to fight many of the infections related to water-borne diseases.
