Who we are

Special services, since 10+ years.

We are a Chennai-based rainwater harvesting specialist. For more than a decade we have advised on, designed and built systems that make every drop of rain count — for homes, apartments, schools and industries.

Broadly, rainwater can be harvested for two purposes:

  1. 01Storing it for ready useIn containers above or below the ground.
  2. 02Charging it into the soilFor withdrawal later — groundwater recharging.

Why harvest rain?

Rain is our primary source of water. Here is why catching it — rather than letting it run off — makes such a difference.

01

An ideal solution where water is scarce

In areas where the groundwater supply is inadequate, or surface resources are lacking or insufficient, rainwater harvesting offers an ideal solution.

02

Uses the primary source of water

It helps utilise the primary source of water and prevents runoff from going into sewers or storm drains, reducing the load on treatment plants.

03

Reduces urban flooding

Holding rain where it falls, instead of letting it rush into streets and drains, helps reduce flooding in the city.

04

Improves groundwater quality

Recharging water into the aquifers helps improve the quality of existing groundwater through dilution.
