It's a matter of when will the pipe fill with dirt and be crushed underground. Driving a riding lawn mower across the earth above this pipe, even walking across it, can cause the pipe to crush and cause a water flow problem it was supposed to be fixing.

Drainage Pipe Slope and Trench Depth Calculation

How deep should a drain pipe be?

Maintaining a depth of 12 to 18 inches is best for drain pipes, but the depth of the pipe may vary in order to maintain a downward slope, which is critical for proper drain functioning.

What is the best pipe to use for underground drainage?

Polyvinyl Chloride pipes (PVC) are the best choice for underground drainage due to their durable nature. PVC pipes are malleable and come in almost any size. These pipes can withstand lots of environmental and water pressure and last for very long periods.

Do I need gravel for solid drain pipe?

Why do I need the extra drainage in gravel: If the pipe connection has a flaw or if the ground shifts a pipe crack could form. If the pipe is backfilled directly with soil the water will collect against the pipe and soil without somewhere to go.

Can a French drain be too deep?

French drain depth: About 8 inches to 2 feet deep should be sufficient for many water-diverting projects, though related systems, such as those built around foundations and sub-ground living spaces, as well as the bases of retaining walls, may be deeper.

How shallow can a French drain be?

The trench should be about 18 inches deep and 9 to 12 inches wide. French drains need to have a slope of at least 1 percent, so the force of gravity will work for you. This means that the drain should slope down a total of at least one inch for every 10 feet of pipe.

How wide of a trench do I need for a 4 inch pipe?

Dig a 6- to 12-inch-wide, 18- to 24-inch-deep channel or trench from the first to the second stake with a shovel. Save the dirt and turf for later use. The depth must be maintained from the bottom of the channel to the string from the first to the second stake.

How do you trench a drain for a yard?

Dig a trench that is 18 inches deep and 9–12 inches wide. Lay water-permeable landscaping fabric in the trench, followed by 3 inches of gravel. Lay your perforated drain pipe in the trench, cover with an additional 3 inches of gravel, and cover the drainage ditch with rocks, soil, or stones.

Should I put rocks in my ditch?

Lining a ditch with rock enhances any ditch. It improves water flow through the ditch, can trap trash and sediment and can reduce erosion. A properly maintained ditch lined with rock can even improve the property value of a piece of land.

How much slope does a drain pipe need?

The ideal slope of any drain line is ¼ inch per foot of pipe. In other words, for every foot the pipe travels horizontally, it should be dropping ¼ inch vertically. Many drains either have too little slope or too much slope. That's right, it is possible to have too much slope in your drain lines.

How deep should a downspout drain be?

The trench must be at least 10-inches-deep, but be aware that in cold-weather regions the pipe occasionally will clog with ice during periods of heavy precipitation.
