The word “Nala” originally meant a natural channel carved out by flowing rainwater as it moved from higher to lower elevations. Nalas function as natural drainage channels whose primary function is to carry surface run-off during the monsoon. Generally, several Nalas join to form a stream (Odha), several streams join to form a small river, and several small rivers join to form a big river, which eventually drains out into the sea.
Over the past 100 years or so the meaning of nala has been transformed into a conduit for sewage and garbage, reflecting a cultural disconnect that has led us to neglect and misuse these water channels and most other wetlands in our cities, towns and villages. At EcoSattva we embrace complexity and design appropriate partnership based interventions to restore nalas, rivers and lakes transforming them back into natural and social assets.

Sewage contains 99% of water and of 1% suspended solids, bacteria etc. If we treat this 1%, the treated water can be used for purposes such as gardening, agriculture and construction.
The Ecologic Sewage Treatment Plants (EcoSTPs) built by EcoSattva offer a sustainable waste-water treatment and reuse solution to campuses and institutions. We create an ecological system which speeds up the natural treatment process by using enzymes, plants, microorganisms and sunlight. The EcoSTP requires minimal power consumption, low maintenance, no chemical inputs and can be integrated into the landscape as a green feature.
