Other brands like Supreme Industries, Vectus Industries and Ashirvad Pipes are listed entities, but specific breakdown for water‑tank business alone isn’t published separately. As a result, their individual market caps attributable to water tanks aren’t publicly documented.
As per industry estimates, the Indian water storage tank market in 2023 was valued at about USD 1.2 billion (~₹ 10,000–12,000 crore).
Market share: The market is highly fragmented—around 70% is dominated by unorganised/regional players, with only 30% share captured by organised/brand players as per JM Financial reports.
Among organised brands, estimates (not precise) suggest Supreme and Vectus may hold ~5–12% share within the organised segment, while Sintex, Plasto, Ashirvad will occupy significant portions. Exact share for each brand is not publicly available.
Why Layers Matter: Understanding Multi‑layer Tanks
Modern HDPE/LLDPE tanks often come in multi-layer builds:
Double‑layer: Outer layer plus UV‑stable inner layer; economical but requires frequent cleaning.
Triple‑layer: Adds a visibility or colour layer; better insulation, UV protection and algae resistance.
Four‑layer: Includes UV shield, antibacterial/heat‑resistant stabiliser, foam insulation and structural layer—ideal for extreme climates.
Five‑ or six‑layer: Premium tanks with added strength, temperature control and aesthetic finish; suited for long‑term use.
Recommendation: For standard climates, a three‑layer tank delivers hygiene and durability. In hot or cold regions, opt for four‑layer or higher.
Significance of Tank Colour
Colour isn’t just aesthetic—it affects hygiene and temperature.
Black tanks: Block sunlight entirely, prevent algae formation and limit bacteria. But they absorb heat, warming water—useful in cooler zones.
Blue/Coloured tanks (e.g. green, violet, orange): Enable visibility, remain hygienic, resist algae and reflect some heat—favoured for drinking water.
White/light colours: Reflect heat, keep water cool; slightly more prone to algae unless UV‑stabilised.
Green: Blends into gardens; moderate algae resistance.
Yellow or high‑visibility colours: Used in industrial or safety contexts.
Choosing tip: In hot sunny areas choose light‑coloured or blue UV‑stabilised tanks; in cooler climates or shaded roofs, black tanks can help keep water warm and algae‑free.
Key Factors to Consider While Choosing a Water Tank
Material: Choose food-grade HDPE or LLDPE for safe water storage.
Layers: More layers (3–6) provide better insulation and durability.
Size: For a 4-member family, a 1000-litre tank is generally ideal.
Shape & Space: Consider vertical tanks for small spaces and horizontal ones for rooftops.
UV Protection: Especially important for overhead tanks exposed to direct sunlight.
Different Shapes of Water Tanks and Their Placement in Homes
Water tanks come in various shapes to suit different spaces, usages, and structural conditions within a home. Choosing the right shape not only improves utility but also ensures safe installation and long-term durability.
1. Cylindrical Vertical Tanks (Round Tanks)
Description:
Tall and upright, with a circular cross-section and dome or flat top.
Ideal Placement:
Rooftops (terrace)
Open platforms beside the house

Efficient use of vertical space
Easier to clean due to shape
Good gravity-based water flow
High structural strength
Common for household use (100L to 2000L+)
Limitations:
May not fit under low roofs
Requires strong platform support
2. Cylindrical Horizontal Tanks
Description:
Lying flat with a horizontal cylindrical body, these tanks are longer than they are tall.
Ideal Placement:
Backyards
Balconies with height constraints
Underground platforms or stand-mounted in open areas
Benefits:
Lower centre of gravity — more stable during storms or high winds
Easier to fit in tight vertical spaces
Often used in industrial and agricultural setups too
Limitations:
Occupies more ground space
Not commonly used in small urban homes

Buried tanks used for bulk water storage, typically made of concrete, FRP, or plastic.
Ideal Placement:
Front yards, driveways, or gardens
Below ground level near building
Benefits:
Saves above-ground space
Maintains cooler water temperature
Ideal for rainwater harvesting or emergency storage
Aesthetically hidden
Limitations:
Costly and complex to install
Requires excavation and waterproofing
Can pose a maintenance challenge

Rectangular or square water tanks often used for community housing, flats, or commercial buildings.
Ideal Placement:
Over building terraces with structural support
Benefits:
High capacity
Can be modular in design
Easy to segment into compartments

How to Choose the Right Shape and Placement
| Home Type | Recommended Tank Shape | Placement |
|---|---|---|
| Small Flats | Loft tank (rectangular) | Inside loft/kitchen |
| Single-floor Homes | Vertical cylindrical tank | Rooftop or outside wall mount |
| Homes with Terrace Garden | Horizontal cylindrical tank | Rooftop or garden corners |
| Multi-storey Buildings | Large vertical or square tanks | RCC platform above terrace |
| Water harvesting setups | Underground rectangular tank | Garden or ground installation |
Installation Tips
Always place tanks on a level, reinforced surface to avoid tilt or rupture.
Use UV-resistant tanks if exposed to sunlight.
Loft tanks must be properly supported to prevent leaks or ceiling damage.
Underground tanks should have proper ventilation, access manhole, and drainage arrangements.
