I'd like to plant bamboo over the drain field of our septic system . In 
"Gaia's Garden", Toby Hemenway mentions that roots clogging the pipes in the 
leach field shouldn't be a problem because bamboo roots don't grow larger 
over time like tree roots do.The bamboos I have are "phyllostachys vivax 
huanwhenzhu" and "phyllostachys angusta (stone bamboo)", both running bamboos 
that would be difficult to remove if there is a problem. The drainfield is 
located in a pasture, perhaps 30 meters into pasture before the drainfield 
starts.I'd fence the bamboo off so that grazing cattle  would keep these 
plants from becoming uncontrollable invaders.Any warnings or comments 
regarding this idea would be appreciated. I live in southern  BC,Canada, 
about 100 km fom the ocean.
