How Effective Are French Drains? (Easy & Clear Answer)

Properly constructed, french drains will work well to transmit water from the pipe to the exit of the pipe; however, they are not very efficient in dewatering poorly drained soils. The best way to determine if a drain is adequate is to measure the water level in the drain and compare it with the soil level.

If the level is too low, it may be necessary to dig a new drain. A good rule of thumb is that a 1-in. For example, if you have a 2-ft (60-m) pipe, a drop of 2 inches (5.4 cm), or even less, would be equivalent in water to a 5-foot (1.2-meter) length of hose.

For example, if a system is designed to drain water from an area of 1,000 square feet to a depth of 3 feet, then the capacity of that system will be about 2,500 cubic feet per minute (c.f. m.p.m.), or about 1.5 gallons per second (g.s.) per square foot of area.

If the same system was designed for a larger area (, a 10-square-foot area), then it would be capable of draining water at a rate of about 3,200 c. f. per m (1.8 g. s. / sq. ft.) or 2.2 gallons/second (2.4 gs./s.).
