Brian Currier (CSUS-OWP). Infiltration definitions. Infiltration rate. : the volume of water flowing into the soil profile per unit of surface area per unit time. Infiltrability. : the infiltration rate resulting when water at atmospheric pressure is made freely available at the soil surface.

Rainwater harvesting means capturing rain where it falls or capturing the run off in your own village or town. It involves taking measures to keep that water clean by not allowing polluting activities to take place in the catchment area.
