Straight answer: underground water lives in the north-east, overhead water lives in the south-west or west. Two tanks, two opposite corners, and one clean logic once it is said aloud.
The logic in one paragraph
Below ground, water is a living element feeding the plot, and living water belongs where water belongs: the north and north-east, the mandala’s water zones. Above the roof, a tank is no longer water first; it is a tonne of weight first, and weight belongs where weight steadies the house: the south-west and west. Confusing the two rules is how most tank doshas are born.
The placements to avoid
No overhead tank on the north-east corner of the roof; that corner stays the lightest point of the entire structure. No underground tank or borewell in the south-west; hollowing the stability corner is the inversion the texts warn about most sternly. The centre of the roof and the centre of the plot both stay free of tanks. The drilling cousin of this rule lives in Borewell Position Remedies, and the drainage cousin in the septic tank guide.
Fixes for houses already built
An overhead tank stuck on the north-east is usually movable at plumbing cost far below the fear it generates; where structure truly forbids it, the corner is compensated by lightening everything else there and strengthening the south-west, sequenced through a Water Tank Position Remedies plan. An underground tank in the wrong corner is managed by usage and by relocating the active draw point where the plot allows.
Common questions
Society building, tank position not in my hands?
Then your unit’s own water points carry your remedy: drinking water to your flat’s north-east, storage barrels off the south-west. Individual discipline still counts.
Two overhead tanks?
Split them across south-west and west rather than doubling one corner’s load, and keep both off the north edge.
Does tank material matter?
Cleanliness matters most. Whatever the material, dark, sealed and regularly cleaned beats symbolic colour choices.
