Our Initiatives
On-ground programmes designed to create lasting environmental and community impact.
Aqua Save Tank
Turning wasted water into a daily resource — one household at a time.
Every RO water purifier in India silently wastes 2 to 3 litres of water for every 1 litre it purifies. Most homes let this water run straight down the drain. The Aqua Save Tank catches it, stores it, and puts it back to work.
The Problem We Are Solving
That is enough water to fill dozens of bathtubs — every year — from just one home. The water is not dirty. It is simply untreated tap water — perfectly usable for cleaning, gardening, and sanitation. It just needs to be caught.
What the Aqua Save Tank Does
TSF built a simple, low-cost DIY system that any household can install: a pipe diverts the RO's reject water into a storage container fitted with a tap. The family uses that stored water for mopping, flushing, washing, and watering plants — every single day, automatically, with no extra effort after the one-time setup.
TSF's first Aqua Save Tank cost ₹300 to ₹500 to build — less than a family dinner out. It has been saving water every day since.
“Our vision is simple: an Aqua Save Tank in every apartment, every school, every office — until reusing water is no longer an initiative. It is just what we do.”
Where We Are Today
TSF has already piloted the Aqua Save Tank on the ground in Solapur. The system works. Families are using it. Water is being saved.
Where We Are Going
Our next phase is scale: residential apartment complexes, schools, hostels, and office buildings. We are actively seeking CSR partners, housing societies, and institutional collaborators to expand the programme citywide.

The Aqua Save Tank Family Handbook
We made a free, illustrated guide to the Aqua Save Tank — designed for families to read together with their children. It explains the problem, walks through the setup, and includes a Water Hero Checklist for kids. Download it, share it, build one.
Free to download and share. Made with 💧 by TSF.
Want to bring Aqua Save Tank to your building or school?
We are looking for housing societies, schools, and CSR partners to install Aqua Save Tanks at scale. If you manage a building, run a school, or lead a CSR programme — let's talk.
Eco Root
Not how many trees are planted. How many trees survive.
The Gap We Are Addressing
India plants millions of saplings every year. Most do not survive past the first monsoon. The problem is not the plantation drive — it is the absence of ownership and follow-through after the cameras leave.
Eco Root is TSF's answer to that gap.
How Eco Root Will Work
Every sapling under Eco Root is community-adopted. A family, a school, or a housing society takes formal ownership of a tree's growth. TSF provides the sapling, species guidance suited to Solapur's climate, and periodic follow-up. The community provides the care.
We track survival, not just plantation.
Eco Root is currently in its planning phase. We are mapping plantation sites across Solapur, building our species selection guide, and onboarding our first community partners.
Express InterestOxygen Point
Self-sustaining vertical gardens — powered by sunlight, requiring nothing but space.
What Is an Oxygen Point?
Oxygen Point is TSF's concept for vertical gardens installed on building walls, compound fences, and institutional spaces. Each installation is fully self-sustaining: a solar-powered drip irrigation system waters the plants automatically — no grid electricity, no daily maintenance.
The result is a living wall that purifies the air, reduces ambient temperature, improves the space aesthetically, and supports local biodiversity — all without ongoing effort.
Oxygen Point is in the concept and design phase. TSF is developing the technical specifications and is looking for pilot installation partners — institutions, housing societies, and corporate campuses with wall or compound space available.
