Installing a SUDS Stormwater Urban Drainage System Tree Pit 

very useful indeed, thank you and greetings from Greece.

My Biggest worry would also be the amount of plastic going in. Is it eco friendly?

Don't know how we can call it sustainable!

How would we calculate the volume of water for this system?? Please i need quick answer for my senior design project

@7:00 why fill with soil and not rocks or gravel?

Too complex, a lot o plastic, expensive to install.

Overly complicated and no doubt expensive.

What a ridiculous excess Just dig a Bloody hole and plant the tree Good grief. Engineers making the simple insanely complex

An over-'engineered' solution to a 'problem'. Or, 'how to blow public money'.

Come on . Over kill or what , so trees aint made it this far with out all that rubbish going in the ground . NOT . Gretta will have something to say about that I'm sure. What an amazing waste of money
