Vastu for Water Tank: Overhead and Underground Tank Direction
Water is a powerful element in Vastu, so where you store it matters. The key rule is easy to remember: underground water goes to the north-east, and the overhead tank goes to the south-west. Here is a clear guide for water tanks, sumps and borewells in a house or plot.
Quick answer
- Underground tank, sump or borewell: north-east, or east or north.
- Overhead water tank: south-west, or west.
- Avoid: an overhead tank in the north-east, and an underground tank in the south-east or north-west.
- Never place either tank in the exact centre of the home.
Underground tank, sump and borewell
Store water below ground in the north-east. This is the water zone in Vastu, and a sump, well or borewell here is believed to support health and prosperity. If the north-east is not possible, the east or north are the next best. Keep underground water out of the south-east and the north-west, which can trouble the people living there.
Overhead water tank
The overhead tank is heavy, so it belongs in a heavy zone. Place it in the south-west, or the west as a second choice. The weight in the south-west is believed to add stability to the home. Avoid an overhead tank in the north-east, where extra weight is thought to cause money and health problems, and never put it in the centre.
| Water element | Best direction | Avoid |
|---|---|---|
| Underground sump / borewell | North-east (then east, north) | South-east, north-west, centre |
| Overhead tank | South-west (then west) | North-east, centre |
| Water flow / drainage | Towards north or east | Blocked or towards south-west |
Why the two go in opposite corners
It looks odd that underground water goes to the north-east while the overhead tank goes to the south-west. The logic is about weight and element. The north-east should stay light and low, so water below ground there is fine, but a heavy tank on top is not. The south-west should stay heavy and grounded, which suits the load of a full overhead tank but not an open water body below.
Remedies if the tank is wrongly placed
In a ready house you often cannot move a tank. Vastu allows a few balance measures:
- Overhead tank in the north-east: use a smaller, lighter tank there and keep the main storage in the south-west. A light colour helps.
- Underground tank in the south-east or north-west: keep it clean and fully covered, and add a water source or plants in the north-east to balance.
- Tank near the centre: shift as much storage as possible to the south-west and keep the central area open.
Treat these as balance steps, not full fixes. Clean, covered, leak-free water is what matters most day to day.
Other water rules
- Keep the tank clean and covered. Stagnant or dirty water is believed to bring negative energy, and it is a health risk too.
- Fix leaks quickly. A constant drip is said to drain money.
- Let drainage and water outflow move towards the north or east.
- If a slight slope exists on the plot, keep it towards the north-east.
- Avoid a black overhead tank in the north-east if you cannot move it; a lighter colour and good upkeep help as a remedy.
These placements are set at the building stage, so they matter most for a plot or an independent house. In a flat the builder decides, so you cannot change them. If you are buying a plot or building, plan the tanks early. See our Vastu for buying a plot and home Vastu tips guides.
FAQ
Where should the underground water tank be as per Vastu?
In the north-east, or the east or north. It is the water zone and supports health and prosperity.
Where should the overhead water tank be placed?
In the south-west, or the west. The weight adds stability to the home.
Can the overhead tank be in the north-east?
No. A heavy tank in the north-east is believed to cause money and health problems. Keep it in the south-west.
Where should a borewell be dug?
In the north-east, or the east if that is not possible.
Why are underground and overhead tanks in opposite corners?
The north-east should stay light, so water below ground is fine but a heavy tank on top is not. The south-west should stay heavy, which suits a full overhead tank.
Which direction should water drain towards?
Towards the north or east. Keep the plot slope towards the north-east where possible.
Is a black water tank bad in Vastu?
A black overhead tank in the north-east is best avoided. If it cannot be moved, a lighter colour and good upkeep act as a remedy.
Can a water tank be in the centre of the home?
No. Keep both underground and overhead tanks out of the exact centre.
Does a water tank direction apply to flats?
Mostly it applies to plots and independent houses. In a flat the builder decides the placement.
Does a leaking tank affect Vastu?
Yes. A constant leak is believed to drain money, and fixing it also prevents real damage and waste.
Remember the simple pair: underground water in the north-east, overhead tank in the south-west. Keep both clean and leak-free, and drain water towards the north or east.
