Banu is a noun that described certain sections of the plumbing system related most directly to sewages leaks -- where the fecal matter meets the open air. There is no solution to this problem, it's like an open wound that will never heal.
I found a banu under the driveway, it was most definitely stinking up a a nearly 300 foot radius of the neighborhood, but what's worse is I can't seem to fix this banu.
