Why Vadodara. The water source that made this possible.

Key takeaways

• Blenders International evaluated eleven source locations across India before choosing Vadodara, Gujarat.
• The decision was driven by measurable water data — favourable TDS and hardness from aquifer water naturally filtered through basalt.
• Vadodara also offered the industrial infrastructure and geological stability needed for consistent, repeatable batches.

The question we get asked most often is not about the mineral profile or the source data. It is simpler: why Vadodara?

The answer is geological, industrial, and — we will admit — somewhat romantic.

The geology

Gujarat sits on the eastern edge of the Deccan Plateau, one of the world’s largest volcanic features. The plateau formed around 66 million years ago through successive lava flows, creating deep basaltic rock formations that underlie much of central and western India.

Basalt is ideal for groundwater filtration. It is highly fractured, creating complex natural filtration pathways, but relatively impermeable at depth — meaning water that percolates through basalt arrives in deep confined aquifers largely protected from surface contamination.

More importantly for our purposes: basalt does not significantly mineralise water. Limestone aquifers (which dominate much of northern India) dissolve calcium and magnesium carbonate into the water at high rates, creating hard water with TDS levels that can exceed 400 mg/L. Our target for Plezure is below 50 mg/L.

The aquifer below Vadodara’s industrial district has a natural TDS in the 30–45 mg/L range. That is a starting point that other locations on our shortlist could not match.

The shortlist

We assessed eleven candidate locations across a two-year research phase:

Himachal Pradesh (multiple sites) — Himalayan glacial sources produce naturally pure, low-TDS water. Excellent mineral profiles. Logistically challenging for a manufacturing base, and the higher elevations introduce supply chain complications. Ruled out on operational grounds.

Pune, Maharashtra — Industrial infrastructure is strong. The water, however, comes from the Mutha River reservoir system, which has variable quality and high seasonal turbidity. Post-treatment costs to reach our spec would be prohibitive.

Nashik, Maharashtra — The wine country of India. Good infrastructure, proximity to agricultural estates. Water TDS in the 80–120 mg/L range — manageable but requiring significant demineralisation. A concern: RO demineralisation of high-TDS water often introduces subtle flavour artefacts that our sensory panels found detectable at fine margins.

Hyderabad, Telangana — High industrial concentration creates potential contamination concerns. Ruled out early.

Vadodara, Gujarat — The winner. The Makarpura industrial estate has pharmaceutical and chemical manufacturing infrastructure (a proxy for process precision). The aquifer TDS is naturally low. The city is well-connected for distribution across India.

The industrial culture

This point is harder to quantify but important. Vadodara has been a centre of precision manufacturing since the 1960s. Baroda Chemical Industries, Indian Petrochemicals Corporation, Alembic Pharmaceuticals — companies whose entire business model depends on process discipline, consistency, and measurement.

The technical talent for the kind of quality-controlled, process-driven production we require exists in Vadodara in a way it does not in smaller towns. When we went to hire our first production manager and quality control lead, both came from pharmaceutical manufacturing backgrounds. They understood GMP compliance. They understood the importance of measurement at every step.

The water house we are building is not a small craft producer making twenty cases a week. It is a precision manufacturing operation. The city of Vadodara, more than any other place we considered, has the culture and the talent for that.

The source

We draw from a bore at 84 metres depth, below the basaltic formation that covers the sub-soil down to approximately 70 metres. At this depth, the water is in a confined aquifer — hydraulically separated from surface contamination by the impermeable basalt layer above.

Temperature at source is consistent year-round at 24–26°C. Pre-treatment TDS: 32–44 mg/L, depending on season (higher in post-monsoon months as seasonal recharge dilutes the static aquifer water). We adjust post-treatment to maintain our below-50 specification consistently.

The source is sampled weekly for microbiological testing and monthly for full mineral analysis by an accredited third-party laboratory in Ahmedabad. Every production run is traceable to the source data for that week.

This is why Vadodara is not incidental. It is foundational.
