Revolutionary rainwater harvesting system storing 3-4 lakh liters per installation. Developed by Prof. Uday Chippalkaty, Pune. Sustainable water security for every building.
Jaloday (Jal-Uday) is an innovative rainwater harvesting system that captures, filters, and stores rainwater underground for year-round use. A game-changing solution for water conservation.
Per Installation
Jaloday, meaning "Rise of Water" (Jal-Uday), is a revolutionary rainwater harvesting technology developed by Prof. Uday Chippalkaty from Pune, Maharashtra. Unlike traditional methods, Jaloday captures every drop of rainwater from your rooftop, filters it naturally, and stores it underground in natural aquifer structures.
The system requires no electricity for its core function, is incredibly cost-effective, and provides long-term water security for residential, commercial, and industrial buildings.
Our 6-step animated process transforms rainwater from rooftops into a reliable underground water source for year-round use.
Rain falls on the rooftop collection area. Every square foot of roof surface captures valuable rainwater that would otherwise be wasted or cause drainage issues.
Collected rainwater flows through roof gutters and downpipes towards the filtration system. The piping network efficiently channels every drop.
Water passes through multiple natural filtration layers removing debris, leaves, and impurities. Sand and gravel filters ensure clean water enters storage.
Filtered water flows into underground storage structures. The natural aquifer system stores 3-4 lakh liters, keeping water cool and protected from evaporation.
Strategically positioned boreholes provide access to stored water. These access points allow controlled extraction and natural groundwater recharge simultaneously.
Clean, filtered water is retrieved on demand via borehole pumps or gravity-fed systems. Ready for domestic use, irrigation, gardening, and industrial applications.

"From rooftops to reservoirs — sustainability simplified"
Jaloday is more than a rainwater harvesting system — it's a philosophy of turning every raindrop into a valuable resource. By capturing rainfall from rooftops and storing it underground, we reduce water bills, recharge groundwater, and secure water futures for communities.
Each Jaloday installation contributes to community water security. When multiple buildings in an area adopt the system, the cumulative effect on groundwater levels is significant — helping sustain wells, borewells, and natural water sources for entire neighborhoods.
See why Jaloday outperforms conventional rainwater harvesting methods in every important metric.
| Feature | Jaloday | Traditional |
|---|---|---|
| Storage Capacity | 3-4 Lakh Liters | 5,000-20,000 Liters (tanks) |
| Electricity Required | Zero (gravity-fed) | Pump needed for extraction |
| Space Required | Underground (no visible footprint) | Large tanks above/below ground |
| Filtration | Natural multi-stage (no chemicals) | Basic mesh/chemical filters |
| Maintenance | Annual cleaning only | Regular chemical treatment |
| Groundwater Recharge | Simultaneous recharge | Minimal or none |
| Water Quality | Naturally filtered & cool | Stagnant, may need treatment |
| Lifespan | 25-30+ years | 10-15 years (tank degradation) |
| Cost Over Time | Very low (near zero annual cost) | Higher (maintenance + electricity) |
| Environmental Impact | Positive (recharges aquifers) | Neutral to negative |
