Piwoslaw,

You are correct in this...

However, part of undertaking PAHS is understanding the soil conditions, especially water table and water transmigration through the soil. To not understand the role of water transmigration in PAHS would be exactly equivalent to not understanding the role that infiltration plays in house insulation.

So site selection of for PAHS implementation is step number 1.

If the water table is low in MMT's area, and if his house is sited so that there is not water flow through the PAHS site it when it rains, burying milk tankers would probably be unnecessary.
