Installing a catch basin in yard
I have a water problem in my yard in which water pools up and runs toward my house.
Under the grass, my soil is mostly clay. I had checked with a local plumber on installing a French Drain across the front of my house & he said with the clay content, a French Drain is not best for my situation.
He suggested a 12" x 12" catch basin with a grate on top of it. He shot the yard with a transit and marked the lowest point in the yard for the catch basin to be installed.
The catch basin will connect in-ground to 4" PVC pipe non-perforated.
The pipe run will be 20 feet from the catch basin to the side of my yard to drain off the excess water.
He then said it would cost me $3500.00 for the catch basin and the pipe and labor.
I think I can do this myself a lot cheaper. $45.00 for the catch basin at big box store, plus 20' of 4" non-perforated PVC drain pipe.
I can dig the 20' trench myself.
After digging the trench and I am ready to put the pipe in the trench, is it OK to just lay pipe on the bottom of the trench itself and then cover it up with dirt, or should I put a layer of sand or gravel in bottom of trench prior to placing the pipe in trench?
Again, the pipe is not perforated and will just empty out on a slope in the side of my yard.
There will be no traffic on the basin grate top or on top of the buried pipe area itself other than just a push lawn mower.
Just wondering if I can just dig a trench, drop in basin and pipe and cover it back up without using rocks and stuff.
