Water solution

Water is the underlying commodity of every product or services (see www.waterfootprint.org)


About 80% wastewater remains untreated which endangers our health, planet and economy.


Prana is a sanskrit word for breath, life and vitality.
The meaning of Prana guides our actions to transform untreated wastewater from a weapon of mass destruction into a range of Planet-saving, profit-making assets such as new water, renewable energy, fertilizers, bio-cements for a sustainable global growth (including financial inclusion and peace).


Our solution, the WasteWater Reuse Exchange - W2AREX® - allocates and organises demands for wastewater by-products or recovered resources with offers of wastewater treatment capacities. The commoditisation of wastewater treatments enables to fund them and scale-up wastewater clean technologies.
The parts of the profits of the wastewater valorisation are for the wastewater provider: this means that even disadvantaged population can get revenues and benefits from their wastewater for financial inclusion.



"Sewage is a commodity and this is a way forward for realising its value for the common good." Dr David Lloyd Owen

"Prana Sustainable Water's guidelines to sell treated wastewater as a new commodity from decentralised sanitation is a good opportunity to separate wastewater qualities for more efficient wastewater treatments to produce energy and fertilisers." Dayanand Panse, Founder director, Ecosan Services Foundation, India.

"Converting treated wastewater into a commodity financed through offers and demands on an organized market can help to solve sanitation finance and water contamination at a large scale", Mr Kajetan Hetzer, Country Partnership Officer for Water Resources Group, International Finance Corporation at World Bank.
