Percolation Law and Legal Definition

Percolation refers to the flow of sub-surface water through land. A percolation test reveals how much water a land can absorb.

The following is an example of a case law on percolation:

Percolation tests reveal, among other things, the suitability of soil for a septic system. For municipal approval of a septic system, Union Township requires two successful percolation tests. [Petrillo v. Bachenberg, 139 N.J. 472 (N.J. 1995)].
