Abstract:
A waste disposal site comprising:a bottom surface having a water-impermeable material covering;at least one sloped side surface having a water-impermeable material covering wherein a surface of said water-impermeable material covering of said sloped side surface is provided with a water retentive or absorptive cover layer in the form of a layer of plants rooted in soil or an artificial material; andwater-impermeable material damage-detecting means comprising electrodes for feeding electricity being disposed on opposite sides of said water-impermeable material coverings thereby forming an electric field about said water-impermeable material coverings, and electrodes for measuring damage to said water-impermeable material coverings being disposed along the water-impermeable material coverings whereby damage to a portion of either of said water-impermeable material coverings is detectable based on an electrical potential variation at said damaged portion when said damage occurs.
