Sanitation

Sanitation must be a global priority : from access to treatment and reuse of wastewater. Even though the world had set as an objective for 2015 to reduce by half the percentage of population that does not have access to basic sanitation, today. 2.5 billion people still do not have access to sanitation (WHO-UNICEF, 2014). Access to toilets for all is a priority that needs to be carried out alongside measures to manage domestic wastewater. In developing countries, around 90% of wastewater is released in the environment without any treatment thus polluting habitats and the ressources for the supply of water and ecosystems (PNUE-UN Habitat ; Sick Water, 2010). The consequences of this delay are enormous in terms of public health, gender equality, preservation of aquatic environments and economic and social development.
