At nine, Nithya Tammana noticed something happening in her own home that many people might have overlooked: clean drinking water was going down the drain while the shower water was being heated.
uncertain
water → notice → drain
Two years later, the girl from Monroe Township, New Jersey, has built a youth-led water conservation network, developed a nature-inspired filter designed to remove lead from school drinking water, and taken her campaign for water sustainability to policymakers.
Her initiative, Save Drop, began in February 2024 with a simple idea - that small, everyday habits and larger infrastructure changes both matter when it comes to protecting water.
asserted
it → build → water
Today, according to environmental organisation Action For Nature, Nithya leads a growing coalition of more than 450 young people known as “Water Warriors”, conducts weekly environmental leadership sessions and has helped students launch more than 100 local conservation clubs.
uncertain
students → accord → clubs
Her work brings together three strands: preventing water wastage, encouraging communities to change everyday practices, and using innovation to address water quality.
asserted
work → bring → quality
“When I realized how much infrastructure, public investment, and energy goes into treating the water that reaches our homes, I knew we had a responsibility to protect it,” Nithya says, in her profile published by Action For Nature.
asserted
Nithya → realize → Nature
“I want young people to know that environmental protection is connected to fairness, and that clean water belongs to everyone.
asserted
water → want → everyone
When we stay consistent and speak clearly, our age doesn't limit our impact- any one of us can change the system.”
asserted
one → stay → system
From a household observation to Save Drop
Nithya’s journey began with a familiar household routine.
asserted
journey → begin → routine
Before a shower, water often runs until it becomes warm enough to use.
asserted
it → run → shower
During that wait, the cold water can be wasted even though it has already been treated for drinking.
asserted
it → waste → drinking
For Nithya, this was not simply about a tap being left open.
asserted
tap → leave → Nithya
It was about the resources required to make water safe and available in the first place.
asserted
water → require → place
One of its central ideas is encouraging the adoption of hot-water recirculation systems, which redirect cold water instead of allowing it to run down the drain while people wait for the shower to warm up.
asserted
shower → encourage → drain
But Nithya did not limit her efforts to asking individual households to be more careful.
asserted
Nithya → limit → households
She also sought policy changes that could make water-saving infrastructure more widely available.
uncertain
infrastructure → seek → changes
According to Action For Nature, she launched a petition calling for such pumps to be mandated in new housing developments.
uncertain
pumps → accord → developments
She also wrote advocacy letters to all 50 US governors.
asserted
She → write → governors
The approach reflects a recurring theme in her work: conservation should not depend entirely on an individual remembering to turn off a tap.
asserted
individual → reflect → tap
Changes in infrastructure, public awareness and policy can also influence how water is used.
asserted
water → influence → infrastructure
Nithya did not limit her efforts to asking individual households to be more careful.
asserted
Nithya → limit → households
She also sought policy changes.
asserted
She → seek → changes
The half-glass idea that asks restaurants to rethink a habit
Another part of Save Drop focuses on a different everyday setting - restaurants.
asserted
part → ask → setting
Through her #ServeHalfGlass campaign, Nithya encourages restaurants to serve customers half-filled glasses of water initially and refill them when requested, rather than automatically filling glasses to the brim.
asserted
Nithya → encourage → brim
When customers are served more water than they need, some of it may remain untouched and be discarded.
uncertain
some → serve → it
Offering a smaller quantity first gives customers the option of asking for more, potentially reducing unnecessary waste.
asserted
Offering → offer → waste
Action For Nature reports that the campaign has already persuaded local establishments in New Jersey to adopt the practice.
asserted
campaign → report → practice
The organisation also estimates that the approach has the potential to save up to two billion gallons of water annually across the United States.
asserted
approach → estimate → States
That figure is a projected potential, not a measurement of water already saved by the campaign.
asserted
figure → project → campaign
Nevertheless, the principle behind the initiative is easy to understand: a small adjustment in how a service is delivered can influence resource consumption across many customers.
asserted
service → understand → customers
For Nithya, the campaign is another way to make water conservation part of ordinary life, rather than something people think about only during a shortage.
asserted
people → make → shortage
BioLayer: a moss-based approach to lead in drinking water
While Save Drop works to reduce water wastage, Nithya has also explored the challenge of water quality.
asserted
Nithya → base → quality
Her innovation, called BioLayer, is a nature-inspired, plastic-free filter made using living
Sphagnum moss.
asserted
innovation → call → ?
According to Action For Nature, the filter is designed to remove up to 95% of lead from school drinking water and costs less than $38.
uncertain
filter → accord → 38
Saving water helps conserve a resource, while removing contaminants addresses whether that water is safe to drink.
asserted
water → save → contaminants
BioLayer represents Nithya’s attempt to apply an environmentally inspired design to the second challenge.
asserted
BioLayer → represent → challenge
The use of living moss is central to the concept.
asserted
use → live → concept
Rather than relying on a conventional plastic-based design, the filter uses a natural material as the basis of its approach to lead removal.
asserted
filter → rely → removal
The stated performance figure is significant, but it needs to be understood precisely: Action For Nature describes BioLayer as being designed to remove up to 95% of lead.
asserted
Action → need → lead
Its profile does not provide further details about the testing conditions, the amount of water treated or the independent validation of the filter’s performance.
asserted
profile → provide → performance
The figure, therefore, should not be taken as a guarantee that the filter will achieve the same result in every setting.
asserted
filter → take → setting
…and 33 more, not listed.
