Resumen
Actualmente, la mejora de la calidad de aguas de los ríos de zonas urbanas como el GAM de San José es un objetivo del Gobierno de Costa Rica. El Instituto Costarricense de Acueductos y Alcantarillados es el líder institucional en saneamiento y depuración de aguas vertidas, el cual dirige y promueve el Proyecto de Mejoramiento del Ambiente del Gran Área Metropolitana de San José, ampliando su red de colectores aproximadamente en 200 km de tuberías con el fin de recoger todas las aguas residuales que requieran tratamiento antes de ser vertidas en un cuerpo de receptor. Para realizar este procedimiento, AyA cuenta con la Planta de Tratamiento de Aguas Residuales Los Tajos, que recibe las aguas captadas por las tuberías y colectores y les brinda tratamiento. De esta manera se obtienen aguas con concentraciones menores de contaminantes y agentes patológicos que serán vertidas nuevamente al cuerpo receptor.
Como resultado de este proceso de depuración se obtienen los lodos residuales, los cuales están compuestos en su mayor parte por material orgánico proveniente de las excretas humanas y residuos domésticos.

The Costa Rican Institute of Aqueducts and Sewers is the institutional leader in sanitation and treatment of discharged water, which directs and promotes the Project for the Improvement of the Environment of the Greater Metropolitan Area of San José, expanding its network of collectors by approximately 200 km of pipes with in order to collect all the wastewater that requires treatment before being discharged into a receiving body. To carry out this procedure, AyA has the Los Tajos Wastewater Treatment Plant, which receives the water captured by the pipes and collectors and provides treatment. In this way, water with lower concentrations of contaminants and pathological agents is obtained, which will be discharged back into the receiving body. As a result of this purification process, residual sludge is obtained, which is mostly composed of organic material from human excreta and domestic waste.
