A system for isolating a dump sitting on the ground has three different structures which are installed under the dump sequentially, as needed. The first structure includes a tunnel driven longitudinally through the ground underneath the dump and an array of drainage pipes passing through the ground and each having a lower end opening into the tunnel and an upper end at the surface. The second structure includes a water barrier in the ground around at least some of the drainage pipes. The third structure includes a water-impervious mass of backfill in a slit underneath the barrier and having a lower end at the tunnel and an upper end at the surface.
