What happens here

Extend the installed French drain system from the patio area to a suitable discharge point, in this case, a storm sewer inlet located further down the yard. This involves continuing the trenching and drain tile installation across the lawn, maintaining the necessary slope for water to flow by gravity. The video confirms a significant elevation drop, ensuring good drainage to the storm sewer.

Goal: Connect the French drain to a distant storm sewer outlet.

Tools and materials

  • Leveling equipment — Verifying the slope over long distances
  • Shovels — Digging trenches
  • 3/4-inch clear rock — Backfilling the trench
  • 4-inch perforated drain tile — Extending the drainage system to the storm sewer
  • Filter fabric — Lining the extended trench

to walking the path right now that's the way Tim works Lane is laughing because he knows that's true don't you've worked with them for a while haven't ya how much of a drop do we have looks like what three four feet that's a good drop in elevation we'll be able to get the drain tile in with no fork no worries because we've got a storm sewer Inlet 3.27 feet so storm sewer inlets so from the top of the patio to the top of the storm sewer and we got 3.27 we got to get one inch to drop per 8 foot of run we have technically we have 78 Lin ears 81 linear feet so we'll call it 80 linear feet so we've got to technically have 10 inches of drop so we've got we've got closer to 36 inches of drop or more we're very good on pitch so we can go more aggressive with our pitch which will help catch the water faster and drain it away this was Blaine's idea good idea blade
