"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"

Wastewater is a mirror of our society and is offering us huge possibilities for a better world.

Imagine that thanks to your smart-metered wastewater you contribute to and benefit from a society leaving no one behind and

– get immediate early warnings, health advice or cares for contagious virus outbreaks,

– know who has grown crops without micro-pollutants and/or if by adding your organic solid wastes thanks to IoT internet of things/bins you get e.g. a free ride on public transport fuelled with renewable energy

– receive or produce yourself biodegradable soap or cosmetics or other products enabling  to add value to your water use (e.g.  ecological disinfectant and detergent  homologated by the Swiss Federal Office of Public Health).

Imagine populations living in smart-resilient cities or villages that can be connected or disconnected from other places in case of pandemic, cyber or other threats. This is possible without jeopardising the local economy thanks to decentralised wastewater transformation hubs securing basic energy, water and food needs.  

Reversing the supply chains to produce what, where and how its makes sense is possible. Planning is indeed governing. Bio-fertilisers, bio-gas, bio-cements and/or bio-polymers and/or other wastewater by-products that are often more efficient, carbon neutral/negative and cheaper than the classical alternatives open good perspectives for local, functional, tasty and organic food security for All and for other basic needs.

There are infinite possibilities to solve simultaneously social, economic and environmental challenges thanks to wastewater this unavoidable resource renewed constantly. 

Mr David Bowie stated  “Tomorrow belongs to those who can hear it coming”. 

Let’s consider wastewater as a gift we receive everyday. You can count on our  work  for no longer wasting the opportunities offered through analysis and transformation of wastewater.

Best wishes,
Best regards,
