What 800+ Organizations Using Zerodor Have Taught Ekam Eco Solutions About Restroom Behaviour in India

The Most Expensive Water Leak in Your Building Isn't a Leak

It's a flush.

When people think about water conservation, they usually think about droughts, reservoirs, rainwater harvesting, or sewage treatment plants. Few think about urinals. Every day, across offices, airports, railway stations, factories, hospitals, malls, and educational institutions, millions of litres of potable water disappear into urinals. Most people never notice it. Facility managers pay for it. Cities struggle because of it. And sustainability teams are under increasing pressure to reduce it.

When facility managers think about water loss, they usually picture dripping taps, leaking pipelines, overflowing tanks, or faulty plumbing. These are visible problems that demand immediate attention. But some of the largest sources of water consumption aren't leaks at all , they're designed into the building itself. Every time a conventional urinal flushes, it uses treated drinking water for a purpose that doesn't necessarily require it. Because the water disappears instantly down the drain, the consumption goes unnoticed, accumulating day after day, month after month.

What makes this "invisible leak" so expensive is its scale. A single flush may use only a few litres of water, which seems insignificant in isolation. However, in a busy office, factory, airport, hospital, or railway station, that fixture can be used hundreds of times every day. Multiply that across multiple urinals, multiple floors, and multiple buildings, and the numbers become staggering. Unlike a broken pipe, which is repaired once discovered, this water loss continues every day as part of normal operations. That's why one of the biggest opportunities for water conservation in commercial buildings isn't fixing a leak , it's rethinking the need to flush at all.

Yet after deploying Zerodor Waterless Urinals across more than 800+ organizations throughout India, we've discovered that one of the most overlooked sources of water consumption exists inside commercial restrooms. From airports and railway stations to manufacturing plants, hospitals, educational institutions, and corporate campuses, our installations have given us a unique view into how Indian restrooms are used , and how much water is unnecessarily consumed every day. What we found challenges some long-held assumptions about restroom design, water conservation, and facility management.

Why This Data Matters

Most discussions about water conservation focus on large infrastructure projects. But in commercial buildings, significant water savings can often be achieved without constructing new treatment systems or expanding storage capacity. The reason is simple. Traditional urinals use potable water for every flush.That means treated drinking water that has already undergone extensive purificationis being used for a purpose that doesn't require it. At the scale of airports, railway stations, industrial facilities, and office campuses, the numbers become staggering.

India's Hidden Water Consumption Problem

When discussions around water conservation happen in India, the focus is usually on shrinking reservoirs, delayed monsoons, groundwater depletion, or large-scale infrastructure projects. While these are critical issues, one significant source of water consumption often goes unnoticed: commercial restrooms. Every day, offices, airports, railway stations, hospitals, factories, malls, and educational institutions use thousands of litres of treated drinking water simply to flush urinals. Because this consumption is spread across hundreds of flushes and buried within utility bills, it rarely attracts attention despite its scale.

The challenge is not that a single flush uses a large amount of water , it's that the process is repeated millions of times across the country every day. What appears insignificant at the fixture level becomes substantial when multiplied across buildings, cities, and years. In a country where water stress is becoming an increasing concern, continuing to use potable water for a task that can be performed without it raises an important question: are we focusing only on the visible water challenges while overlooking the everyday systems consuming vast amounts of this precious resource?

What Ekam Eco Learned from 800+ Organizations That Chose Zerodor

1. High-Traffic Facilities Consume Water at an Unimaginable Scale

One of the strongest patterns we observed across 800+ organizations installations is the direct relationship between footfall and water consumption. Facilities such as airports, railway stations, bus terminals, stadiums, shopping malls, and large public institutions experience a constant flow of users throughout the day. While a single flush may use litres of water, the cumulative effect of hundreds or even thousands of daily restroom visits can result in an enormous water consumption. Because this usage is spread across the day and hidden within overall utility costs, the scale often goes unnoticed.

What makes high-traffic facilities unique is that even small improvements can create a significant impact. A water-saving measure that seems modest in a low-occupancy building can translate into hundreds of thousands of litres saved annually in a transportation hub or public facility. These environments taught us that the true cost of restroom water use is not determined by the amount used per flush, but by how frequently that flush occurs. The higher the footfall, the greater the opportunity to reduce unnecessary water consumption and achieve meaningful sustainability outcomes.

2. Manufacturing Facilities Waste More Water Than Most Realize

Manufacturing facilities are often highly focused on managing process water, cooling systems, production efficiency, and wastewater treatment. As a result, restroom water consumption rarely receives the same level of attention. Because the water used in employee restrooms is typically bundled into overall utility costs, it becomes a hidden expense that goes unnoticed. Yet in facilities operating multiple shifts with hundreds or even thousands of workers, restroom usage can be significant, leading to the consumption of large volumes of treated water every single day.

What surprised us across many industrial installations was how often organizations discovered restroom water savings only after examining their overall consumption more closely. While substantial investments are made to optimize manufacturing processes and reduce industrial water use, conventional urinals continue to consume drinking water with every flush. In many cases, switching to waterless technology proved to be one of the simplest and fastest ways to reduce freshwater consumption without affecting operations, productivity, or employee experience. Sometimes, the biggest water-saving opportunities aren't found on the production floor , they're found just outside it.

3. Corporate Offices Have a Different Challenge

Unlike airports, factories, or railway stations, corporate offices typically experience more predictable restroom usage patterns. The challenge isn't necessarily the volume of water being consumed , it's visibility and accountability. As organizations increasingly commit to ESG goals, sustainability targets, and environmental reporting, every aspect of resource consumption comes under scrutiny. Water usage that was once considered a routine operational expense is now becoming an important metric that stakeholders, investors, and employees expect companies to monitor and reduce.

What we observed across corporate installations is that sustainability teams are looking for solutions that deliver measurable results without disrupting workplace routines. Employees shouldn't have to change their behaviour for a conservation initiative to succeed. Waterless urinals offer exactly that advantage. They reduce freshwater consumption automatically, helping organizations achieve tangible sustainability outcomes while maintaining the same user experience.

4. Users Adapt Faster Than Expected

One of the most common concerns organizations have before installing waterless urinals is user acceptance. Facility managers often wonder whether employees, visitors, or customers will notice the difference, resist the change, or require special instructions. However, across more than 85,000+ installations, we found that these concerns rarely become reality. Most users interact with a waterless urinal exactly as they would a conventional one, making the transition virtually seamless. In many cases, people don't even realize they're using a waterless fixture unless it's specifically pointed out to them.

This taught us an important lesson about sustainability initiatives: the most successful solutions are often the ones that require the least behavioural change. People are busy, and expecting them to constantly adjust their habits can limit the effectiveness of conservation efforts. Waterless urinals remove that barrier entirely by delivering savings automatically in the background. Rather than relying on awareness campaigns, reminders, or behaviour-driven programs, the technology itself reduces water consumption , allowing organizations to achieve measurable sustainability results without changing the user experience.

5. The Biggest Concern Is Usually Smell

Whenever organizations consider switching to waterless urinals, the first question is always about odor. Many people naturally associate cleanliness with water and assume that removing the flush will lead to unpleasant smells. It's a common perception, especially among facility managers who are responsible for maintaining user satisfaction and responding to complaints. However, our experience across more these installations has shown that odor issues are rarely caused by the absence of water itself.

In reality, restroom odors are more often linked to poor maintenance practices, drainage issues, biological buildup, or improper system design. We've seen conventional urinals that flush hundreds of times a day still develop odor problems, while properly maintained waterless urinals remain clean and odor-free. Water doesn't automatically solve odor problems, and the lack of water doesn't automatically create them. Effective restroom hygiene depends on good maintenance and the right technology. Once organizations understand this, concerns about smell often disappear, replaced by a greater appreciation for the water-saving benefits that waterless systems provide.

Manufacturing vs Corporate Offices: Two Different Water Challenges

One of the most interesting observations emerged when comparing manufacturing facilities with corporate offices.

Manufacturing Facilities

Manufacturing plants typically monitor production water closely. Process efficiency, cooling systems, and wastewater treatment often receive significant attention. Yet employee restrooms are frequently overlooked. Because restroom consumption is blended into overall utility bills, many organizations underestimate how much water is being used outside production processes. In several cases, facility teams discovered that reducing restroom water consumption offered one of the fastest sustainability wins available.

Corporate Offices

Corporate offices generally experience lower restroom traffic than factories or transportation hubs. However, they face increasing pressure from sustainability reporting requirements, ESG commitments, and environmental targets. For these organizations, waterless urinals are not simply a water-saving technology. They become a measurable sustainability initiative that contributes directly to resource conservation metrics.

The Water Waste Equation Most Organizations Never Calculate

Let's simplify the math.

Imagine a conventional urinal that uses 2 litres per flush.

If it is used 150 times per day:

• Daily Consumption: 300 litres

• Monthly Consumption: 9,000 litres

• Annual Consumption: 108,000 litres

That's for just one urinal. Now imagine a facility with 20 urinals. The annual consumption exceeds 2 million litres of potable water. And that's before considering high-footfall environments such as airports, railway stations, shopping centres, and large institutions. What appears to be a small flush quickly becomes a major operational and environmental cost. Suddenly, restroom flushing becomes one of the easiest water-saving opportunities available.

Why Waterless Technology Is Becoming an ESG Priority

Environmental, Social, and Governance (ESG) commitments are no longer limited to sustainability reports and annual disclosures. Organizations are increasingly expected to demonstrate measurable action, particularly when it comes to resource conservation. Water has emerged as one of the most critical ESG metrics, especially in regions facing growing water stress. As companies look for practical ways to reduce their environmental footprint, they are beginning to examine areas of consumption that were previously overlooked. Restrooms are one such area, where conventional fixtures continue to use thousands of litres of treated drinking water every year without adding meaningful value to the user experience.

What makes waterless technology particularly attractive from an ESG perspective is that it delivers measurable impact without requiring behavioural change. Every litre of water saved can be quantified, tracked, and reported as part of an organization's sustainability efforts. Unlike awareness campaigns that depend on continuous participation, waterless solutions generate savings automatically from day one. As investors, customers, employees, and regulators place greater emphasis on environmental performance, organizations are realizing that ESG success isn't just about large-scale projects , it's also about eliminating everyday inefficiencies. Waterless technology represents a simple yet powerful way to align operational practices with long-term sustainability goals.

The Biggest Myth About Waterless Urinals

The biggest myth about waterless urinals is that they must smell bad because they don't use water. For decades, people have associated flushing with cleanliness, making it easy to assume that removing water will automatically create hygiene and odor problems. As a result, odor is often the first concern raised by facility managers, maintenance teams, and decision-makers when evaluating waterless technology. It's a reasonable question , but one that stems more from perception than reality. After installations across hundreds of organizations, we've found that the presence or absence of water is rarely the primary factor determining restroom odor.

In reality, unpleasant smells are usually caused by factors such as poor maintenance practices, drain blockages, biological buildup, or improperly designed plumbing systems. Conventional urinals can develop odor issues despite using thousands of litres of water every month, while properly maintained waterless urinals can remain clean and odor-free. The lesson is simple: water masks symptoms, but it doesn't necessarily solve the root cause of odor. Modern waterless urinal technology is specifically engineered to control odors while eliminating unnecessary water consumption, proving that effective hygiene and water conservation can go hand in hand.

What 85,000+ Installations Tell Us About the Future

After more than 85,000 installations, one trend is becoming increasingly clear: the future of water conservation will be driven less by awareness and more by smarter infrastructure. Organizations across industries are realizing that sustainability goals cannot rely solely on changing human behaviour. While awareness campaigns play an important role, the greatest and most consistent resource savings come from technologies that eliminate waste automatically. The facilities leading the way are not necessarily the ones asking people to use less water, they are the ones redesigning systems so less water is needed in the first place.

These installations also reveal a broader shift in how organizations think about sustainability. Water conservation is no longer viewed as a standalone environmental initiative; it is becoming a business priority tied to operational efficiency, ESG performance, cost savings, and long-term resilience. As water scarcity becomes a growing concern across cities and industries, organizations will increasingly question every use of treated drinking water and ask whether it is truly necessary. The future belongs to solutions that deliver measurable impact without compromising user experience, and the widespread adoption of waterless technology suggests that this shift is already underway.

A Shift in Thinking

Perhaps the most important lesson from thousands of installations is that water conservation is no longer just about using less water , it's about using water more intelligently. For decades, organizations have focused on reducing consumption through awareness campaigns, signage, and behavioural changes. While these efforts have value, they often depend on people making the right choice every single day. Today's sustainability leaders are taking a different approach. Instead of asking users to conserve water, they are investing in technologies and systems that eliminate unnecessary consumption altogether.

This shift represents a broader change in how organizations view sustainability. Water is no longer seen as an unlimited utility that simply arrives when needed; it is increasingly recognized as a valuable resource that must be managed responsibly. As water stress, utility costs, and ESG expectations continue to rise, businesses are beginning to question long-standing practices that were once accepted without scrutiny. The conversation is moving from "How can we reduce water use?" to "Do we need to use water here at all?" And that change in mindset is where meaningful, long-term conservation begins.

Conclusion

Across railways, airports, hospitals, factories, educational institutions, and corporate offices, one pattern remains consistent:Waterless urinals represent one of the simplest opportunities to reduce freshwater consumption without affecting user experience. The findings from more than 85,000+ installations suggest that India's next major water-saving opportunity may not be found in a dam, reservoir, or treatment plant. It may be found in the restroom. Because when every flush uses water, every flush has a cost. And when millions of flushes happen every day, that cost becomes impossible to ignore.

Frequently Asked Questions (FAQ)

1. Why did Zerodor conduct this study?

After working with more than 800+ organizations and completing over 85,000 installations, we gained access to one of India's largest real-world datasets on commercial restroom usage. The goal was to understand how restroom behaviour, water consumption, and facility management practices impact overall water use across different sectors.

2. What types of organizations were included in these insights?

The findings are based on installations across a wide range of facilities, including airports, railway stations, hospitals, manufacturing plants, corporate offices, educational institutions, shopping malls, and public infrastructure projects.

3. Why are commercial restrooms an important part of water conservation?

Commercial restrooms consume significant amounts of treated drinking water every day. While a single flush may seem insignificant, the cumulative impact across thousands of users and multiple facilities can result in millions of litres of water being consumed annually.

4. How much water can a conventional urinal use?

Water consumption depends on the fixture and usage frequency. In high-traffic environments, conventional urinals can consume substantial amounts of water over the course of a year due to repeated flushing.

5. What did the study reveal about high-traffic facilities?

The study found that airports, railway stations, shopping centres, and other high-footfall locations have the greatest potential for water savings. Even small reductions in water usage per visit can create a significant impact when multiplied across thousands of daily users.

6. What makes manufacturing facilities different from corporate offices?

Manufacturing facilities often focus on process water and wastewater treatment, while restroom water use remains largely unnoticed. Corporate offices, on the other hand, are increasingly focused on ESG reporting and sustainability metrics, making water conservation a strategic priority.

7. Do people notice when a waterless urinal is installed?

In most cases, users adapt immediately because there is no change in how the fixture is used. One of the key findings from the installations was that user acceptance is typically much higher than organizations expect.

8. Do waterless urinals smell?

This is one of the most common misconceptions. Odor issues are generally caused by poor maintenance, biological buildup, or drainage problems rather than the absence of water. Properly maintained waterless urinals can remain clean and odor-free.

9. Why is waterless technology becoming important for ESG initiatives?

Organizations are increasingly required to demonstrate measurable sustainability outcomes. Waterless technology provides quantifiable water savings that can support ESG goals, environmental reporting, and resource conservation strategies.

10. What is the biggest misconception about restroom water use?

Many organizations assume that restroom water consumption is relatively small compared to other operational uses. However, when calculated annually across multiple fixtures and facilities, restroom water use can represent a significant source of waste.

11. Can waterless urinals help reduce operating costs?

Yes. By eliminating flush water consumption, organizations can reduce water usage and support long-term resource efficiency. The exact savings depend on facility size, footfall, and existing water consumption patterns.

12. What does the future of restroom sustainability look like?

The future is moving toward smarter infrastructure that reduces waste automatically. Organizations are increasingly adopting technologies that deliver measurable environmental benefits without requiring changes in user behaviour.

13. What is the most important lesson from 800+ organizations and 85,000+ installations?

The biggest lesson is that people are not usually the source of water waste—systems are. Meaningful conservation often comes from improving infrastructure and technology rather than expecting users to change their habits.

14. Why should facility managers care about restroom water consumption?

Because it is one of the few areas where significant water savings can be achieved without disrupting operations, affecting productivity, or changing user behaviour. It represents a practical and often overlooked opportunity for sustainability improvement.

15. How can organizations evaluate whether waterless urinals are right for them?

Organizations should assess restroom footfall, current water consumption, sustainability objectives, and long-term operational goals. Facilities with high restroom usage often see the greatest environmental and operational benefits from waterless technology.
