Best Direction for Overhead & Underground Water Tank

Every factor of building a house must be done as per Vastu. Even to the extent that one must pay attention to features like the water tank. Vastu placement of water tanks holds tremendous importance because water is considered one of the five elements of nature or Panchatattva – earth, water, fire, air, and space.

When you arrange these five elements per Vastu, the house maintains harmony and offers its occupants many advantages. But if they are unequally distributed, it changes the balance and invites various issues.

In modern homes, overhead plastic tanks have become very common. These tanks hold hundreds of litres of water. This enormous weight of water storage is an essential element since it may affect the flow of energy in the home. Incorrect placement can lead to health and financial issues, while correct placement can benefit health and prosperity.

Understanding Two Types of Water Tanks in Vastu

As per Vastu, there are two places where most people keep their tanks – overhead and underground. Both respond differently to different locations.

1. Overhead Tank = Weight Element
Overhead tanks are placed on the roof. A lot of weight is exerted on the house. So in Vastu, overhead water is treated as Earth element, not just Water.

2. Underground Tank = Water Element
Underground tank is built by digging ground. It is pure Jal element and holds water at lower level, which is ideal for North-East.

Overhead Water Tank Vastu – Best Directions

To get best outcomes, the overhead water tank should be located in the southwest or west corner of the house. This is the golden rule.

Here are the 3 Best Positions for Overhead Tank:

1. West & South-West – Absolute Best
The absolute best Vastu placement for an overhead water tank is between the West and South-West directions. Water, when placed overhead, is considered an earth element and the best placement for earth elements is between West and South-West. It gives stability, ownership and prevents property loss. Ensure the South-West area is not kept empty.

2. South Direction – Second Best
As per Vastu, water tank placement in the South is also a great option when placing it overhead. This direction is associated with fire which harnesses energy and transformation. It brings passion, vitality and positive energy when weight is placed correctly.

3. West Direction – Third Best
Placing overhead tank in West is also Vastu-compliant. Such placement encourages communication, progress and vibrancy in the house.

What if South-West / West is not possible?
If those areas are inaccessible, you should place the tank in the South or North-West direction. However, if placed in North-West, ensure that size of tank is as small as possible and place it at a distance of three feet from the North-West corner.

Overhead Tank Vastu – Where NOT to Place

You should never locate the tank in the North-East corner as it is against Vastu Shastra. Placing the tank in the South-East corner or Centre (Brahmasthan) is also not recommended as it can result in loss of wealth and cause accidents.

Never place water tank above these 3 places:
Never place a water tank above your bedroom, main entrance, or kitchen. Doing so can lead to unnecessary problems related to health and finances. People sleeping in bedroom below tank may experience tension, sleep difficulties and anxiety.

Additional Critical Rules:

1. Platform Rule: Even if you’ve picked perfect South-West spot, don’t place tank directly on roof slab. You should always build a raised platform at least 1-2 feet high. This creates gap between water and house’s skull, allowing energy to circulate underneath.
2. Corner Distance Rule: Don’t push tank right into absolute 90-degree edge of building. Keep it at least 2 feet away from corner. This avoids corner stress.
3. Leakage Rule: If tank is placed in South-West corner, take care that there are no water leaks from the tank. Leakage in SW directly affects stability and finances.

Underground Water Tank Vastu – Best Directions

The underground tank is generally built by digging up ground under house. Location of tank should be towards North-East direction of plot. Consider building towards North and East direction. When placed in North-East, tank can bring happiness, wealth and prosperity.

3 Best Positions for Underground Tank:

1. North-East (Ishan Kon) – Best
Considered best placement for underground tank. It is expected to harness all kinds of happiness and prosperity into home.

2. North Direction – Second Best
As per Vastu, North is associated with acquisition of prosperity, wealth and happiness and is ruled by Kuber.

3. East Direction – Third Best
Placing underground tank in East also symbolizes wealth gain and overall prosperity.

Where NOT to Place Underground Tank:
Never locate an underground tank in the South as it can cause mental health issues. Also avoid placing it in North-West, South-West, or South-East corner of house.

Digging Rules:
It is recommended to do pooja before digging earth. However, you should never dig ground on a Tuesday. The tank shape should be square or rectangular, not round. Slope of plot should be towards North-East where tank is.

Water Tank Colour As Per Vastu

Vastu colours have significant psychological impact. Right colour for tank enhances results.

• Tank in North-East (Underground): Any light hue of brown or green, or off-white is ideal.
• Tank in South-West (Overhead): Yellow, grey and white are best colours. Avoid orange, green, brown, blue and black.
• Tank in West (Overhead): White, yellow, grey and black are best. Avoid red, orange, green and brown.
• Tank in South (Overhead): Red, yellow, green, orange and brown are best. Stay away from blue, white, grey and black.

For most homes, the best universal colours are white, beige or light yellow for overhead tanks. Avoid dark blue and black plastic tanks if possible, especially in South-West.

Material of Water Tank – Plastic vs Stainless Steel

While most default to black plastic tanks, Vastu experts in 2026 are leaning heavily toward Stainless Steel (SS) tanks. Plastic is seen as tamasic material – essentially dead energy that can affect quality of water it holds. Steel is much more neutral and hygienic.

If you can’t do steel, look for multi-layer tanks. Colour inside matters because water has memory. A white or blue inner lining helps maintain purity and cooling properties, whereas a dark or dirty interior can make energy feel heavy.

Vastu Dosh – What Happens With Wrong Placement?

You might have Vastu dosh if you place tanks incorrectly:

• Tank in North-East (Overhead): Becomes heavy, results in health difficulties, money troubles and challenges with children’s education.
• Tank in South or South-West (Underground): Lives of family members become unstable, financial instability, mental stress.
• Tank in Brahmasthan (Centre): Severe Vastu flaw, health issues for all members.
• Tank above Bedroom: Tension, anxiety, sleep disorder.
• Tank above Kitchen: Fire and water clash, health and financial problems.

Vastu Importance of Keeping Tanks Clean

Regular maintenance is essential not only for health but also from Vastu perspective. As per Vastu Shastra, flow of energy or prana within living space greatly influences well-being and prosperity.

• Energy Flow: Water represents wealth. Clean tank ensures uninterrupted positive energy flow.
• Health and Purity: Stagnant water or dirty tanks harbour negative energies and lead to health issues.
• Financial Stability: Water is linked to financial stability. Well-maintained tank symbolises smooth flow of wealth.
• Balance and Harmony: Keeping tanks clean maintains harmony and positive atmosphere.

Remedies If You Cannot Shift Tank

Only changing tank’s direction to proper location will give best results. But if you cannot shift, try these remedies:

1. For Overhead in North-East: Shift to West as soon as possible. Temporary remedy – paint tank light yellow and keep it as small as possible, raise platform.
2. For Overhead in South-East: This is fire zone. Keep tank away, or if not possible, paint it white and keep water level low.
3. For Underground in South: Fill it and make new one in North-East. This is most serious dosh. No colour remedy works fully.
4. For Leakage: Repair immediately. In Vastu, leakage = money leakage.
5. Consult Expert: If unsure of best course to counteract impacts of Vastu dosh, consult Vastu specialist with your house map.
