Curtain drain is at ground level. French drain is at the bottom of footer.
If you are having problems with Water shed. Water running down hill on top of ground. Ditch or curtain drain may be an option. A true curtain drain should be 2x2 full of gravel. The gravel works as a filter, collecting the water and taking it away form the surface.
But if you are concerned with water in crawl space or basement, a curtain drain will not take care of the problem. Water runs downhill, even under ground. In growing areas these problems may also be worse. Development disturbs water’s natural course and it must find a new path.
A French drain typically sits at least 8 feet below the ground, at or below the footing. The French drain is a pipe covered with filter fabric. Do you know a filter that does not need to be changed? At some point the pipe will clog. Depending on settlement and type of soil is a factor in how long a French drain will work. This area has a lot of clay soil, which tends to clog faster.
Assume the French drain is a pipe 4” around. Now look a few years down the road and add 1” debris to 4”pipe; you only have 3” pipe for water to flow. Fast forward a little further, 2” of debris now only 2” pipe for water flow. And so on, before you know it you have more water than this narrow drainage canal can handle. Heavy rains, higher pressure - can’t handle the flow.
