What Went Wrong With Sintex? The Rise, Fall, and Takeover of India’s Iconic Water Tank Brand

Sintex is one of those Indian brands that lived in every home, every street, and every industrial site — often quietly, in the form of a white plastic water tank perched on a terrace. What many people do not realize is that Sintex’s story began not with plastics, but with textiles. It started its journey as Bharat Vijay Mills (BVM) in 1931, evolved into a plastics giant, ruled an entire consumer category, made a series of high-risk corporate decisions, collapsed under debt, and finally found new life under two of India’s biggest industrial groups.

This is the complete story of how it began, why it rose so fast, what mistakes led to its downfall, and how it eventually got split and acquired by new owners.

1. The Beginning: Bharat Vijay Mills (1931–1990s)

The roots of Sintex go back to 1931, when The Bharat Vijay Mills Ltd. was established in Kalol, near Ahmedabad. It started as a textile mill manufacturing cotton fabrics, yarn, and later high-quality specialty textiles. For decades, BVM operated like a typical Indian mill of the pre-liberalization era — steady output, a loyal workforce, and gradually modernizing machinery.

By the 1960s and 70s, competition in textiles grew, margins started shrinking, and Indian consumers were slowly moving toward synthetic fabrics and new materials. The management at BVM saw the writing on the wall and wanted to diversify. This decision would change the company’s destiny.

2. Enter Plastics: The Birth of the Sintex Brand

In the late 1970s and early 1980s, Bharat Vijay Mills made its most transformative move: it entered the plastics business. The company began manufacturing plastic products, experimenting with moulding technologies, and exploring the potential of rotational moulding — a technique that could produce large, durable, seamless plastic containers.

This is where the Sintex brand was born.

Initially, Sintex produced:

  • Industrial plastic containers
  • Chemical storage tanks
  • Packaging solutions

But soon, they realized the massive need for domestic water storage in Indian homes. Traditional metal tanks were heavy, rust-prone, and expensive. Sintex introduced something revolutionary:

The Lightweight, Rust-Free, Long-Lasting Plastic Water Tank

It was:

  • Easy to transport
  • Easy to install
  • Affordable
  • Highly durable
  • Available in multiple sizes

Consumers embraced it instantly. By the early 1990s, Sintex tanks became a household name, and the company became the undisputed market leader in water storage solutions. Their branding was so powerful that the word “Sintex” became synonymous with “plastic tank” — just like Xerox for photocopying and Colgate for toothpaste.

3. The Big Transition: Bharat Vijay Mills Becomes Sintex Industries

As plastics overtook textiles in revenue and popularity, the company officially rebranded:

Bharat Vijay Mills → Sintex Industries Ltd

This wasn’t just a cosmetic change — it reflected a complete shift in identity. Sintex was no longer a textile mill; it was now an emerging conglomerate with deep ambitions across materials, infrastructure, and international expansion.

4. How Sintex Ruled the Plastic Tank Market

By the 2000s, Sintex dominated the Indian market with:

1. Product Innovation

They kept introducing new tank designs — horizontal tanks, underground tanks, multi-layer tanks, anti-bacterial tanks — and maintained strong R&D.

2. Massive Distribution Network

Sintex built one of the largest dealer networks in the country, ensuring availability in every city, town, and village.

3. Strong Branding & Recall Value

The name “Sintex” was printed in bold black letters on white tanks. Over time, that visual itself became the brand identity.

4. Government & Infrastructure Projects

Sintex supplied products for:

  • Rural water supply programmes
  • Sanitation projects
  • School infrastructure
  • Shelter and prefabricated building solutions

5. Early Mover Advantage

They were one of the first companies to truly scale plastic rotational moulding in India. This advantage cemented their leadership for decades.

At their peak, Sintex controlled nearly 60–70% of the organized plastic tank industry — an incredible dominance rarely seen in Indian manufacturing.

5. The Mistakes: Overexpansion, Overborrowing, and Overcomplexity

Despite being a cash-rich business, Sintex made a series of strategic missteps that gradually led to its downfall.

1. Aggressive Debt-Funded Expansion

Sintex began expanding into:

  • International custom moulding
  • Prefabricated building solutions
  • High-end composite materials
  • New textile capacities

Much of this expansion was funded by heavy borrowing. As long as cash flow was strong, this didn’t seem like a problem — but it created a fragile financial structure.

2. The 2017 Demerger: A Complicated Corporate Structure

In 2017, the company split itself into two major listed entities:

  • Sintex Industries Ltd (Textiles)
  • Sintex Plastics Technology Ltd (Plastics)

The idea was to “unlock value”, but the opposite happened:

  • Investors got confused
  • Debt remained high on both sides
  • Share prices crashed
  • Analysts began questioning governance decisions

3. Market & Cost Challenges

The company was hit by:

  • Rising cotton prices
  • GST transition impact
  • Slowdown in infrastructure spending
  • Cheaper competitors in plastic tanks
  • Falling margins in custom moulding

4. Defaults and Rating Downgrades

By 2019, Sintex began defaulting on its debt and non-convertible debentures. Rating agencies sharply downgraded the company. This triggered:

  • Frozen credit lines
  • Loss of investor confidence
  • Increased interest burden
  • Pressure from lenders

5. The Final Blow: Insolvency Proceedings

Creditors dragged both Sintex entities to the National Company Law Tribunal (NCLT) under the Insolvency and Bankruptcy Code (IBC).

This marked the end of Sintex as an independent empire.

6. The Downfall: Collapse Under Debt

Once insolvency began:

  • Promoters lost control
  • Shareholders lost almost all value
  • Lenders faced big haircuts
  • The brand was up for sale

The once-iconic Sintex Group — that ruled terraces across India — was dismantled into separate auctions for textiles and plastics.

7. The Aftermath: Two Sintexes, Two New Owners

A. Sintex Industries (Textiles) – Bought by Reliance & ACRE

The textile business, originally from the Bharat Vijay Mills lineage, was acquired by:

  • Reliance Industries Ltd (RIL) – 70%
  • Asset Care & Reconstruction Enterprise (ACRE) – 30%

Reliance infused new capital, taking over operations in 2023.

B. Sintex-BAPL (Plastic Tanks) – Bought by Welspun Group

The famous Sintex plastic tank business went to the Welspun Group, one of India’s largest conglomerates in pipes and building materials.

Welspun acquired:

  • The brand
  • The manufacturing facilities
  • The dealer network

This means Sintex water tanks now belong to Welspun, not the original Sintex promoters.

8. What Sintex Means Today

Sintex exists today, but not as the company India grew up with:

  • The textiles business lives on under Reliance
  • The plastic tank brand lives on under Welspun
  • The old Sintex corporate group is gone

Yet, the name survives because it was too strong and too deeply rooted in public memory to disappear.

Conclusion: A Classic Indian Corporate Story

Sintex’s journey captures the entire arc of Indian industry over a century:

  • A mill born in pre-independence India
  • A visionary diversification into plastics
  • Iconic brand leadership in domestic water storage
  • Misjudged expansions and excessive debt
  • Collapse and insolvency
  • Rebirth under new industrial giants

It is a reminder that even the strongest brands can fall if financial discipline is ignored — and that in the world of business, brand value may outlive the company that created it.
