Tree selection near septic field Canada zone 5b

Dan0

Hi,
I live in canadian plant hardiness zone 5b. My front lawn is about 80 long x 60 wide feet. It is now bare of trees and there is only grass between my house and the road. My spectic field is under my front lawn but I think I should be safe to plant a row of trees about 10-feet back from the road? I know I shouldn't use willow, aspen, poplar, maple etc... because of their invasive roots. I was thinking of White, red or Austrian Pine since they are very wind firm and also evergreen. How are the roots of these trees in regards my spectic field? Is there any advantage of one over the other in regards to my spectic system? Is there any other tree you'd recommend? Birch? Larch? Linden? Crab apple, pear etc.. Their main purpose would be for screening. They would be in full sun and very exposed to wind and ice damage. My main concern is finding something that will not mess up my septic field.


Thanks!

I need more specific engineering details of the septic.

Depth, construction and how fluids are dissipated ... for example are there external drainage pipes tree roots could navigate?

Do you have a site plan showing the layout so we could establish proximity of the plantings etc.

Some septics here have a grey water subterranean dispersal matrix, meaning a network of slotted drains that slowly leak water out under the lawn.

I don't know much about septic systems other than they cost huge sums of money to replace. Is it really wise to plant any trees over a septic field?

Here's the drawing I have:




Thanks: I believe I have about 15-20 feet between the last distrubution pipe and the ditch that separates my lawn from the road.


THANKS!
