Soggy yard? I found the last owner's buried drain (DIY French drain alternative)

By Jacob Knapp, Virginia-licensed home inspector, Virginia Beach. When I started digging my soggy yard, I found a buried drainage tub the previous owner had installed with a single grate, then given up on. It was covered in dirt with grass growing over it. One grate was never going to fix this yard, so I kept their tub and built a real system around it.

Steps

1. Call Miss Utility (VA811) before digging.
2. Probe and dig around low spots and old grates; look for buried pipe ends or a tub.
3. Clean out and keep what still works (I kept the old tub as a dry well, wrapped in landscape fabric).
4. Add surface grates where water actually stands after rain.
5. Connect them with solid, solvent-glued PVC, checking slope the whole run.
6. Outlet to a pop-up emitter lower than the inlets, away from the house and neighbors.
7. Buying a home? Look for grates buried under sod, pipe ends that go nowhere, and soggy low spots, and ask the seller in writing about drainage work.

Materials

• Existing buried tub (reused as a dry well)
• Landscape fabric
• Surface drain grates
• 3–4 inch solid PVC pipe, fittings, primer and cement
• Pop-up emitter
• Shovel, level or string line

What I did in my own yard, not an engineered spec. Check your local code and call 811 before you dig.
