Solving Standing Water and Fungus with a French Drain (Big-O Pipe)

A Springfield, MO homeowner has standing water in a low backyard corner where four yards meet, caused by neighbors' daily irrigation. They suspect fungus and ask about rubber barriers, raised beds, or other fixes.

Install a Perforated Drain Pipe (Big-O)

• 10-inch diameter perforated flexible pipe buried in a 2–2.5 ft deep trench with slight slope (6-inch drop per 100 ft).
• Wrap pipe in landscape fabric; cover with pea gravel to top of pipe; backfill 8–10 inches soil; reseed.
• Outlet to a low area or a dry well (3x3x3 ft hole filled with large rocks).

This intercepts subsurface water and redirects it, eliminating the soggy corner and associated fungal issues.
