The water problem: a fundamental source of life and development

Having water to sustain the life of communities means much more than just water for drinking, but to be able to develop ecosystems adapted to their own needs that allow them not only to survive, but also to develop properly.According to UN data (2024), 2.2 billion people lack access to safely managed water and 3.5 billion people lack access to safely managed sanitation.Wastewater treatment is an answer to both the lack of water for agriculture and livestock, allowing communities to prosper and improve their environment, as well as to improve their ecosystem by preventing contaminated water from contaminating groundwater and soils.Finally, models of social investment projects are developed, with their characteristics and parameters that allow the correct measurement of the investment -both public and private- in the recovery and treatment of wastewater.
