Groundwater Recharging

We have developed a new method of groundwater recharge, called 'V-wire injection well' technology. This allows for the groundwater table to be replenished and thus abate water scarcity.

Modern TechnologyModern Technology

'Rainy' filters are made with highly durable, food-grade material and have self cleaning capabilties to auto-flush out debris.

Dual Intensity FiltersDual Intensity Filters

Our filters work on the principle of cohesion & centrifugal force. This enables filtering at variable intensity of rainfall without affecting the efficiency.

No External Energy RequiredNo External Energy Required

Works on Gravitational Force and does not require any external energy. Low gravitational head of just 1 feet makes it feasible for installation on any building.

Groundwater Recharging

‘V-wire injection well' technology is used to recharge groundwater source and replenish the water table. Run off rainwater is made to pass into a silt trap through a channel and then to an injection well. Here, it goes through multiple filtration media and is eventually passed on to a specially designed storage well. The storage well has dual non clogging V-Wire screens attached to a percolator pipe. The clean water is then made to percolate into deep layers of the earth's strata, ultimately recharging the groundwater source and replenishing the water table.
