Rewriting the Story of Water: rejuWATER® and the Future of Sustainable Sanitation

The Water We Waste: A Reality We Can No Longer Ignore

Take a moment and imagine this: You’re brushing your teeth. The tap is running. You flush the toilet. A strong stream of clean water disappears into the drain. You wash your hands, and yet more water vanishes, unseen. All of this is so routine, we don’t even think about it. But here’s something we must all start thinking about—humans are probably the only land species that defecate and urinate in water. No other animal does that.

This might sound shocking at first. But think about it—most other species defecate on soil or open ground, where nature begins its own process of decomposition and recycling. Meanwhile, we humans have built a system where we mix our biological waste with the planet’s most precious resource: water. Clean, fresh, drinkable water.

And then we use more water—via the flush—to send that waste away. Where does it go? Most of the time, we don’t know, and sadly, we don’t ask.

The Addictive Design of Flush Toilets

The modern flush toilet is a marvel of engineering, no doubt. But it’s also a trap. We’ve become so used to this system of hygiene that we cannot imagine life without it. Generations have grown up believing that the toilet must flush, that waste must vanish instantly, and that the tap must flow freely. We’re addicted to the design.

But every flush, every drop from the tap, adds up. Every time we send waste away using water, we contribute to two crises: *water scarcity* and *water pollution*.

The problem is not just that we use water to carry waste. The bigger issue is what happens after the waste leaves our homes. In most cities and towns, untreated or partially treated sewage flows into lakes, rivers, and oceans. The result? Toxic water bodies, vanishing aquatic life, and poisoned groundwater.

This is no longer a third-world problem. It’s a global crisis.

The Water Crisis is Real and Growing

India, where over 1.4 billion people live, is facing a water crisis of alarming proportions. According to a NITI Aayog report, nearly 600 million people in India are experiencing high to extreme water stress. In cities like Bengaluru, Chennai, and Delhi, groundwater levels are plummeting. Rivers are drying. Lakes are foaming with chemicals. In rural areas, women walk miles to fetch a few buckets of water.

And still, we flush.

Even in homes with good intentions, people are unaware of how much water is wasted. A single flush uses 5 to 10 liters of water. Multiply that by the number of family members and flushes per day, and you’ll realize that toilets alone can account for over 30% of household water usage. In commercial complexes, offices, malls, and apartment buildings, the waste is multiplied many times over.

Is it too late to change this? Maybe not.

The Moral Responsibility of Returning Clean Water

If we borrow water from nature, it is our moral duty to return it in the same condition. This is not just an environmental concern—it’s a matter of ethics and responsibility. The water we use and pollute today is the same water our children and their children will need to survive.

We cannot continue to add human waste, detergents, food scraps, and chemicals to our water sources and then expect the Earth to clean it for us. Nature cannot keep up with the level of pollution we’re generating.

But here’s the good news: solutions exist.

From individual households to large residential communities and commercial entities, everyone can adopt simple yet effective technologies that clean and recycle used water. One such solution is rejuWATER®.

Introducing rejuWATER®: Smart Sewage Treatment for Every Scale

rejuWATER® is a modern, efficient, and eco-friendly wastewater treatment system designed to address the very problem we’ve created—polluting water with our daily waste. Whether you live in an independent home, a gated community, or manage a commercial building, Rejuwater has a solution that can work for you.

What is rejuWATER®?

rejuWATER® is a decentralized sewage treatment system that treats black water (from toilets) and grey water (from kitchens, washing machines, and showers). Using a combination of natural biological processes and advanced engineering, it purifies the water and makes it reusable for non-potable purposes like gardening, flushing, floor cleaning, and landscaping.

Instead of sending water away and never thinking about it again, rejuWATER® helps you close the loop—reuse what you consume.

How Does It Work?

rejuWATER® systems typically use a series of treatment stages that may include:

1. Primary Treatment: Removal of solid waste and separation of oils and grease.

2. Biological Treatment: Use of naturally occurring microorganisms that consume organic matter and break down contaminants.

3. Filtration & Settling Tanks: The treated water passes through various filters (gravel, sand, carbon, etc.) to remove fine particles.

4. Disinfection: UV or chlorination methods are used to disinfect the water, making it safe for reuse.

All of this happens in a compact unit that requires minimal maintenance, runs on low power, and does not produce foul odors.

Why Choose rejuWATER®?

• Environmentally Responsible: By treating and reusing water on-site, you prevent contamination of natural water bodies and reduce your water footprint.

• Cost-Effective: Treated water reduces the need for tanker water or excessive borewell use, which translates into significant monthly savings.

• Compliance-Ready: Rejuwater helps residential communities and commercial entities meet pollution control board norms and avoid legal penalties.

• Scalable: Whether you need a 500-liter per day unit for your home or a 1 lakh-liter per day plant for a township, Rejuwater has modular solutions that scale as per your requirement.

• Plug-and-Play: The systems are easy to install and integrate with your existing plumbing without major civil work.

Who Should Use Rejuwater?

1. Independent Homes: Small Rejuwater units can help households reuse kitchen and bathroom water for gardening and flushing.

2. Apartment Complexes: Communities can reduce their freshwater intake by up to 50% by reusing treated grey water for flushing and landscaping.

3. Commercial Buildings: Offices, hotels, hospitals, malls, and factories can cut operational costs and earn green certifications.

4. Schools and Institutions: Safe, odor-free systems ensure compliance and set an example for students and staff.

5. Farmhouses and Resorts: Off-grid locations benefit the most by recycling water for gardens, animals, and crops.

Beyond Technology: A Mindset Shift

Of course, technology alone is not the answer. What we need is a fundamental shift in how we view wastewater. It’s time we stop seeing it as “waste” and start seeing it as “resource water.” With proper treatment, this water can serve multiple needs, reduce our dependence on groundwater, and prevent pollution of lakes and rivers.

This is a call not just for technology adoption, but for behavioral change.

• Let’s stop thinking of flushing and forgetting.

• Let’s stop allowing sewage to poison our rivers.

• Let’s start thinking in cycles—use, treat, reuse.

Imagine the Impact

• A single apartment complex with 200 flats can save over 3 million liters of water each month using rejuWATER®.

• A gated community with 1000 residents can reduce its sewage discharge to near zero.

• A commercial building can cut tanker costs by over 40% and get certified as a green building.

These are not just numbers—they’re steps toward a more sustainable and water-secure future.
