How should I make it?
Rain water harvesting
It is practiced in a variety of ways depending upon topography, soil and rainfall.
|
Micro-catchments
-
Inter-plot water harvesting uses a portion of land with 5% slope as catchment to generate runoff
-
Runoff water is then channeled into the lowest point and collected in an infiltration pit/pond
-
Size of catchment area is generally twice of the cultivated area with 5% slope on both sides of the plot
-
Capture and storage areas are within a small distance.

Macro-catchments
-
Catchment is usually 30-200m in length
-
Size of catchment area is generally twice of the cultivated area
