Water Storage for Commercial & Industrial Buildings: SMC Tank Sizing Guide

Commercial and industrial buildings simply cannot afford to run out of water. It does not matter whether you are dealing with a hospital, factory, business complex, or shopping centre; a constant water supply is not only convenient, but it is essential for daily routines, hygiene, and even safety in some cases. 

But choosing the right tank capacity can be tricky. That’s where SMC panel tanks come in, and at Sintex, we make the decision easy for you. We have reached out and engaged with architects, constructors, and facility managers all over India, and we know there’s no one-size-fits-all solution. 

Occupancy, water demands, peak uses, or emergency water reserves, to name a few, are the necessary points we are categorising in this guide so you can have a better idea of what SMC panel tank, underground water storage tank, or FRP underground water tank to select that fits your building.

Why SMC Panel Tanks Are the Ideal Choice for Commercial Spaces

Our SMC panel tanks are built for scale. They are flexible; you can change the size according to the site’s needs. The panels can be installed quickly and cost-effectively in small commercial facilities as well as multi-storey complexes.

They also last long. These tanks are made of sheet moulding compound material, which is weather-resistant, maintenance-free, and corrosion-free. Above all, they fulfil every hygienic requirement and can be used to contain potable water, process water, or even emergency fire storage.

So, when does it make more sense to go underground? Our FRP underground water tanks are equally dependable, offering reinforced structural strength with excellent leakage prevention.

How to Calculate the Right Tank Size

Let’s get into the math, but don’t worry, we’ve kept it simple.

When sizing an SMC panel tank, the key variables include:

• Number of occupants (employees, visitors, residents, etc.)
• Daily water consumption per person (usually 50 to 150 litres)
• Peak usage window (in offices, this is typically 9 AM to 12 PM)
• Fire safety water reserve (as per local fire safety guidelines)
• Contingency buffer (to cover maintenance downtime or delivery delays)

Here’s a simple breakdown:

Don’t forget to add at least 25% extra for firefighting and emergency use, especially if your local building codes require it.

When to Choose an Underground Tank

There are instances where rooftop or above-ground storage isn’t feasible due to limited space, height restrictions, or architectural constraints. That’s where our FRP underground water tanks come in. Designed to resist soil pressure and moisture ingress, these tanks are great for:

• Basements or parking-level installations
• Large industrial sites where ground area is available
• Projects where aesthetics matter and visible tanks aren’t ideal

All our underground water storage tanks come with leakproof technology and high resistance to soil chemicals, ensuring long life and safe storage.

Modular Flexibility, Quicker Installation

With Sintex SMC panel tanks, you’re not stuck with a preset shape or size. Need a 50,000-litre tank? 1,00,000 litres? Or a multi-compartment system with separate chambers? No problem. Our team configures the tank layout based on your site conditions.

Another win: installation is fast. Unlike traditional RCC tanks that require curing time and extensive civil work, our panel systems are ready to go within days. That means less downtime and quicker project handovers.

Why Choose Sintex?

We’ve been part of India’s water storage story for decades. And when it comes to SMC panel tanks, FRP underground water tanks, or any underground water storage tank, we’re trusted across sectors from schools and factories to airports and five-star hotels.

With products like our Sintex Pure Plus and Sintex Pure Antimicrobial tanks, we’ve also brought Active Silver Technology to commercial settings, offering 4P protection (anti-virus, anti-bacteria, anti-fungus, and anti-algae). Combine that with a 15-year warranty and ROHS European compliance, and you’ve got tanks built to serve for decades.

Maintenance Tips for Long-Term Tank Health

Here’s how to get the most out of your Sintex tank:

• Clean the tank interior at least once every 6 months
• Install first flush systems for rainwater collection tanks
• Check joints and seals annually for modular SMC panel tanks
• Use UV-protected covers for open-top tanks to reduce contamination
• Install air vents and overflow pipes to avoid water stagnation

With our support and quality engineering, your tank won’t just store water; it will protect it.
