Rainwater harvesting & water management solutions

Site-specific rainwater harvesting, groundwater recharge, stormwater management and afforestation for homes, institutions and industries across Keralam, Karnataka and Tamil Nadu.

01Decentralized storage

Site-specific rainwater harvesting

We design your property to catch its own water — filtered, stored, and ready to use — so you rely a little less on the tanker or the municipal line, and the ground beneath you gets a little healthier every monsoon.

Stormwater management solutions

When the rain comes hard and fast, we make sure it has somewhere good to go — routed safely away from your building, and guided toward the aquifers that need it, instead of flooding the street.

Afforestation & Miyawaki forests

On land that’s gone bare, we bring back dense, native forest — the kind that heals soil, holds water, and quietly pulls carbon from the air. It’s slow work that pays off for decades.

≈ 150,039 Liters captured per year

Based on standard impervious surface runoff coefficient (0.85). Actual yield may vary with roof material, slope, and local weather patterns. Contact us for a detailed site assessment.

Hardware & infrastructure

Dedicated product integrations

Some jobs call for a complete system. Others just need the right piece. Our product range works both ways — as standalone tools, or built into a larger Skyra Rainsink system.
