This is what happens when you get the right solution on the right location.
This is something we talk about a lot, and it's crucial to your project.
Without this principle in place from the start, your rainwater management project is:
Which means, you're more likely to miss spill reduction goals, project validation and face fines.
This graph shows monitoring data from two interventions that we've been tasked with monitoring.


Ari says
The one on the left is a very expensive planter on a roof in the South of England. In the substantial rainstorm on the 15th of February the water level in this planter never reached even 10% of the planters' capacity - meaning 90% of that capacity is wasted sitting around waiting for a bigger storm! This device has been installed on far too small a roof for its attenuation rate and volume - wrong solution for this location!
Ari continues
Compare this with the one on the right - a cheap retrofit attenuation tank on a roof in the West of England. In that very same storm this intervention filled to nearly 90% capacity, before draining back down to around 20% (this intervention keeps the last 20% for reuse). This is a much better use of all that available attenuation volume, it's the right attenuation volume and rate for the roof area - a perfect illustration of right solution, right place!


Right place right solution is one of our core principles when we implement a rainwater management project.
Effectively our guiding light.
This combined with your goals means no more guess work, but instead measurable impact backed up by data.
All neatly packed on our rainwater management platform.
