Early stage commercial environment application

A TRL is a measure to indicate the matureness of a developing technology. When an innovative idea is discovered it is often not directly suitable for application. Usually such novel idea is subjected to further experimentation, testing and prototyping before it can be implemented. The image below shows how to read TRL’s to categorise the innovative ideas.

There is an increasing need for rainwater harvesting and buffering in urban settings. Field Factors developed a multipurpose modular and scalable neighbourhood-scale system that buffers, purifies and distributes rainwater.


The system is easily integrated in urban areas. Its Lego-like components are configured into a ring-like structure, with a biofilter in the middle. The components can quickly take up and store rainwater, and slowly release it into the biofilter.


This system could support the current 100.000 km long sewage system. First commercial applications of the system have been initiated and a demonstrator is under development at The Green Village.
