Just a suggestion - I had a couple of guys do the same thing in my yard -
they tied the downspouts into the drain, and had a few additional surface
drains to carry the rainwater away. In my city, there are some fairly
stringent code considerations as to HOW the end of the discharge pipe has to
exit onto the street, HOW to tunnel under the sidewalk, etc.. - they don't
like ya just dumping drain water out onto the sidewalk, or undermining the
sidewalk and then just breaking up the curb and doing a lousy patch job.

Obviously getting the right slope of the pipe over the entire length is
important or it won't drain, but only one of the guys that came out to
estimate the job actually did anything more than just eyeball it - in my
yard there wasn't a lot of drop from the front to the back after sinking the
beginning of the pipe in the back yard - the slope was critical - my guy got
it right, but I can see how it'd be a nightmare if ya didn't know what
you're doing. Sometimes, the slope of the ground plays visual tricks on ya.

My next door neighbor and I want to put in some 3 or 4 inch PVC pipe
into the ground to carry away rainwater from the gutters away from the
back of the property to the front lawn where it can find it's way to
the driveway & street sewers.

It's about 100 foot length and for most of it the pipe woud be just
under the surface.
for the last 30 feet or so the ground rises so that would require
deeper digging.
I don't think the depth would get over a foot at the steepest part of
the lawn.
We'd then angle the pipe downhill until it emerged from the ground
again (my street is sloped)

Would the trencher Home Depot rents be sufficient for this - anybody
have experience with it or are there other types of trenchers to rent
from other stores that would be better suited.
I could always go the shovel & pick route or try to hire someone, but
am interested in anybody's personal experience and/or knowledge. thanks
