We have surface water from uphill which collects in a 40 foot long
puddle ten feet uphill from our house during large storms.

After it saturates the soil, water comes into our basement at a depth of
eight feet.

We have lived here 35 years and the pattern is quite clear - with
flooding only two times in that period, and so I hope we might use a
shallow French drain to move the water sideways to an open slope.

(I know that the ideal French drain goes all the way to the bottom of
the problem, but that would cost many thousands of dollars in our case.)

I would start at a depth of one foot and run 100 feet to a two foot
depth at the exit.

I would use rock and landscaping fabric around the pipe.

Your opinions about this approach?

Can I get away with a 1/8" per foot slope?

Should I use 2, 3, or 4 inch drain pipe?

Should I use landscaping fabric aroound the rock as well?

Thank you for your ideas.

Sincerely,

Dwight Gibb


1/8" slope will work OK, esp since you won't
be dealing with any solids.

Use 4" pipe (you can use the thinwall sch 35).

Not sure about the fabric, but we'll bump
your mssg to the top for more replies. g
