The more wastewater is treated, the more nature can clean for free the environment, preserve the ecosystems and reduce greenhouse gas emissions and the water//energy nexus.


On the wastewater supply side, smart metered wastewater resources are valued according to the difficulty to treat them: Prana Sustainable Water helps responsible products to become more competitive than products generating heavy noxious wastes and/or to get incentives.


On the treated wastewater purchase side, Products/Services produced with treated effluents can be traced towards a circular economy approach and reported for their positive impact.


Prana treated wastewater is allocated according to the water exploitation index and/or in priority for basic human needs (e.g. 2000 liter /day/capita as minimum water footprint for dignity with 1 liter water for 1 calorie + water footprint for clothes, housing, etc.).


Buffers stocks of commoditized treated effluents are set-up in order to reduce water price volatilities and as insurance tool to face adversity.
