World Water Monitoring Day 2026: The Water We Don’t Notice We’re Wasting

Water monitoring usually brings to mind rivers, lakes, groundwater levels, water quality reports and large environmental projects. But there is another kind of water monitoring that happens much closer to home inside our buildings. Every office, airport, mall, hospital, factory and institution has its own hidden water story. Water enters the building, moves through kitchens, washrooms, cooling systems and other operations, and eventually leaves as wastewater. We often monitor the big numbers while overlooking the small, repeated uses that add up every day. A urinal is a good example.

A conventional flush urinal can use water every time someone uses it. One flush may look insignificant. Multiply that by hundreds of users, multiple urinals, long operating hours and 365 days, and a small fixture becomes a surprisingly large water consumer. That is why water monitoring should not stop at the main water meter. It should also make us look at where water is being used, why it is being used, and whether it is actually necessary.

Water Conservation Starts With Better Visibility

For facility managers, a water audit can reveal leaks, excessive consumption, inefficient fixtures, cooling-tower losses, landscaping demand and opportunities to reuse treated wastewater. But which uses of freshwater can simply be eliminated? That distinction matters.

Improving efficiency means using less water to perform the same task. Eliminating unnecessary consumption goes one step further. This is where waterless sanitation becomes relevant.A urinal does not fundamentally need water to transport urine into the drainage system. The flushing water has traditionally become part of the process because that is how conventional plumbing has been designed. Zerodor takes a different approach.

Why Zerodor? Because Monitoring Water Is Only Half the Job

Knowing that a building is consuming too much water is useful. Doing something about it is where sustainability becomes real. Zerodor is a waterless urinal technology developed by Ekam Eco Solutions with roots in IIT Delhi research. Instead of using repeated flushing, it uses a mechanical one-way valve. Urine passes into the drain, while the valve closes afterward to help prevent sewer gases and unpleasant odour from coming back into the restroom.

There is no flushing water involved. There is no electricity requirement, no oil sealant and no regular cartridge dependency in the core mechanical system. It can also be retrofitted into existing urinals, making the change possible without replacing an entire restroom setup.That makes Zerodor particularly interesting from a facility-management perspective. It is not asking people to change their behaviour. It is changing the infrastructure behind the behaviour.

One Small Fixture. A Big Water Opportunity.

According to Ekam Eco Solutions' 2026 impact reporting, Zerodor has crossed 85,000+ installations across 800+ organisations, with reported cumulative water savings of 3.5+ billion litres. Ekam estimates that an individual Zerodor urinal can save 150,000+ litres of water per year, depending on usage and the conventional fixture being replaced. The significance of those numbers is not just the litres saved.Every litre of water that does not need to be used for flushing also avoids the energy, treatment, pumping and wastewater handling associated with that unnecessary consumption. This is why water conservation needs to move beyond the idea of simply asking people to use less. The smarter solution is to redesign the system so less water is needed in the first place.

The Odor Problem Is Part of the Engineering

One of the biggest concerns around waterless urinals is also one of the most understandable: odor. For decades, people have associated flushing with cleanliness. More water feels like more hygiene. But flushing does not automatically solve the source of odor.

Zerodor approaches the problem mechanically. Its valve allows urine to drain while creating a barrier against sewer gases and odour returning through the drainage line. The system is designed to eliminate the need for continuous flushing rather than simply covering up the smell with fragrance. That difference is important. Water should not have to be the price we pay for an odor free restroom.

From Water Monitoring to Water Action

A water meter can tell a facility manager how much water the building is consuming. A water audit can show where that consumption is happening. But the real sustainability opportunity comes from the next step identifying the consumption that can be reduced, reused or eliminated.That could mean fixing leaks, improving cooling-tower efficiency, harvesting rainwater, reusing treated wastewater or replacing water-intensive fixtures. Zerodor fits into that larger water strategy by removing one recurring demand altogether: flushing water from urinals. For high-footfall buildings, this becomes especially relevant. Airports, malls, offices, factories, hospitals, educational institutions and public facilities can have hundreds or thousands of restroom users every day. At that scale, even a small amount of water saved per use can become a meaningful annual reduction.

Water Monitoring Should Change the Way We Design Buildings

The next generation of sustainable buildings will not be defined only by solar panels, green roofs or rainwater harvesting systems. They will also be defined by the everyday systems that quietly determine how much water, energy and material a building consumes. A sustainable building should not simply measure its water consumption. It should continuously ask where that consumption can be avoided. That is the bigger lesson behind World Water Monitoring Day. Monitoring gives us the numbers. Engineering gives us the solutions. Good design makes those solutions part of everyday life. And sometimes, one of the simplest places to start is the restroom.

Choose Zerodor When the Goal Is More Than Just Saving Water

For organisations looking at water conservation as part of their ESG, BRSR, green-building or operational strategy, Zerodor offers a practical place to begin. It combines zero flushing water, mechanical odour control, low recurring dependency and retrofit-friendly installation in one simple sanitation intervention. More importantly, it turns water conservation from an awareness campaign into an infrastructure decision. Because the future of water conservation will not be built only by finding new sources of water. It will be built by designing buildings that need less of it. And sometimes, the biggest water-saving opportunity is sitting quietly in the washroom waiting to be noticed. This World Water Monitoring Day 2026, don't just monitor how much water your building uses. Monitor where you can stop using it. Explore Zerodor waterless urinals

FAQs

World Water Monitoring Day & Zerodor

Q1. What is World Water Monitoring Day?

World Water Monitoring Day is an awareness initiative that encourages people and organisations to pay attention to water quality, water resources and the way water is managed. It highlights the importance of monitoring water so that problems can be identified and addressed early.

Q2. Why is water monitoring important for buildings?

Buildings can consume large amounts of water through restrooms, kitchens, cooling systems, landscaping and other operations. Monitoring helps facility teams understand where water is being used and identify opportunities to reduce unnecessary consumption.

Q3. How much water can a urinal consume?

The consumption depends on the fixture, flush volume, number of users and frequency of use. When multiplied across multiple urinals and hundreds of daily users, flushing can add up to a significant amount of water over a year.

Q4. What is Zerodor?

Zerodor is a waterless urinal technology developed by Ekam Eco Solutions. It uses a mechanical valve that allows urine to drain while helping prevent sewer gases and unpleasant odour from returning into the restroom.

Q5. Why choose Zerodor for water conservation?

Zerodor eliminates the need for regular flushing in urinals, helping buildings reduce recurring water consumption. It can be particularly useful in high-footfall facilities where urinals are used frequently throughout the day.

Q6. Does Zerodor use any flushing water?

No. Zerodor is designed as a waterless urinal system, so there is no need to flush the urinal after every use.

Q7. How does Zerodor control odor without flushing?

Zerodor uses a mechanical one-way valve. Urine passes through the valve into the drainage system, while the valve helps prevent sewer gases and odour from travelling back into the restroom.

Q8. Can Zerodor be installed in an existing restroom?

Yes. Zerodor is designed for retrofit applications, allowing suitable existing urinals to be converted to a waterless setup without replacing the entire restroom infrastructure.

Q9. Does switching to waterless urinals mean compromising hygiene?

Not necessarily. Water usage and hygiene are separate considerations. Proper restroom cleaning, maintenance, drainage design and user practices remain important. Zerodor specifically addresses the need for flushing water while providing mechanical odour control.

Q10. Who can benefit from Zerodor?

Offices, airports, malls, hospitals, factories, schools, colleges, railway facilities, government buildings and other high-footfall locations can consider Zerodor as part of their water-efficiency strategy.

Q11. How does Zerodor support ESG and sustainability goals?

By eliminating recurring flushing water from urinals, Zerodor can contribute to a building's water-efficiency efforts and broader sustainability initiatives. It can be considered alongside other measures such as rainwater harvesting, wastewater reuse and leak management.

Q12. Is monitoring water consumption enough?

Monitoring is the starting point, not the finish line. Once a facility identifies where water is being consumed, the next step is to reduce, reuse or eliminate unnecessary consumption. That is where solutions such as Zerodor become relevant.

Q13. What is the bigger message of World Water Monitoring Day?

The goal is not simply to know how much water we use. It is to understand our consumption and make better decisions about it. Measure the water. Find the waste. Redesign the system. Save what we can.
