I think it was two weeks before I got
around to the second phase of the
project
. The plan was to run the drain pipes into
an underground sump. Lowes had these cool plastic sump
thingys that was
perfect.
Over time your drain field
will fill with silt and other debris that washes down the
drain. Eventually it renders your drain area useless and
everything backs up. With this cool sump thingy (which comes
with a lid), I could dig it up and more easily clean
out the crap.
At least that was the
plan.

With the whole elevation change thing
going on, I had to string up some lines to figure out exactly
how far down the yard I had to go with the sump. From the lid
of the sump, I was going to add an overflow pipe and vent, so
when the sump got full of water, it had somewhere to go. The
key was making sure the overflow vent was lower in elevation
in the yard then either of the catch
basins.
Unfortunately the yard sort of levels out
after the corner of the garage, so I had to go quite
a ways to make sure the overflow would
work.
Considering the drain pipes had to also
make a constant drop in elevation, that meant a lot of digging
for me out and down into the yard. Which by the way, turned to
clay about twelve inches
down.

You can see I had a lot of digging to do
to get the sump
down to the correct
depth.
|
|
|
Almost there. Notice the
water in the bottom? We have a very wet
yard.
|
|
|
Finally it's
deep enough! Unfortunately I didn't measure the final depth of the
hole.
|
|
|
I lined the hole with drain fabric, though
now that I look at
it.
|
|
|
Then ran all the
pipes.

Here's the step-down from the sidewalk

And finally where it all comes together in
the
sump. |
