Leach field drainage
#1

We have 8 lines in our leach field. One came up and we capped it. the one next to it came up and we capped it too. Why does the water keep coming to the surface? Our septic tank has been pumped out. The land slopes downward. the soil is clay. Would a raised bed solve the problem?

The leach field soil is clay? That is the problem. Contact your local septic permitting department, and get them to design a solution. Building up sand over the leach field won't necessarily solve anything. You will probably need to add more drain lines. Good Luck!
