Tree roots and pipes - a question

[Gary Prentice]

Yeah I know what you mean. As I say, just a thought that sprung into my head. Theoretically, it's great, though logistically and economically perhaps not so much.

 

 

 

 

 

Roots usually get in via joins / cracks. Indeed, the condensation, reduced compaction around pipes (especially beneath), and the much warmer surrounds of foul pipes compared to the nearby soil (all that human waste - gives off some heat!). If the inner pipe was made of HDPE or what have you it could, in theory, work more effectively, and indeed the trees could still use moisture that resides within the space between the two pipe walls. I was trying to think in a way that balances the needs of proper underground pipework and giving the trees the moisture usually lacking in urban areas, as hardly anywhere has stormtmater irrigation reservoirs below the surface to support trees.

Unfortunately not and David's a fairly prolific thread starter (of informative and interesting threads). I'm sure David will remember the thread I'm thinking of.
