India Can Lead Global Water Management with Nature-Based Innovation, Says Expert

India has the potential to become a global leader in sustainable wastewater management through nature-inspired technologies. ECOSTP Technologies has developed a system mimicking a cow's stomach that treats sewage without electricity or chemicals. The company has treated over 9 billion litres of wastewater across India and expanded to Bangladesh, the Maldives, and Africa. The technology has been recognized under Startup India and appreciated by Prime Minister Narendra Modi.

India can lead sustainable water management through nature-based innovation: Expert

Dalian, June 25

India has the potential to become a global leader in sustainable wastewater management by adopting nature-inspired technologies that reduce energy consumption and improve water reuse, an expert said.

Speaking to IANS on the sidelines of World Economic Forum's Annual Meeting of the New Champions -- known as Summer Davos -- , Bharathan said India's growing wastewater challenge presents an opportunity for indigenous innovations to create environmental and economic impact.

He noted that nearly 80 per cent of the country's sewage remains untreated, leading to severe pollution of rivers, lakes and other water bodies.

ECOSTP Technologies has developed a wastewater treatment solution inspired by biomimicry, a technique that imitates natural processes. The company has replicated the functioning of a cow's stomach to treat sewage without the use of electricity, chemicals or mechanical equipment.

According to Bharathan, conventional sewage treatment systems rely heavily on aeration processes that require significant energy consumption and operational costs.

In contrast, the company's gravity-based system uses specially developed bacteria and underground chambers that mimic the four compartments of a cow's stomach -- the rumen, reticulum, omasum and abomasum -- to naturally treat wastewater.

The technology was developed in collaboration with IIT Jammu and is designed to convert sewage into reusable clean water without the need for operators, moving parts or continuous power supply. Bharathan said the company has treated more than 9 billion litres of wastewater across India through its installations.

The startup currently serves customers in 24 states and has expanded its presence to Bangladesh and the Maldives. The company is also entering African markets, including Mozambique and Kenya, to offer sustainable water treatment solutions.

Bharathan said India's wastewater crisis is not merely a governance issue but a technological challenge, as existing treatment systems often remain expensive and energy-intensive. He added that nature-based solutions are particularly suited to Indian conditions and can play an important role in improving water conservation and reducing environmental pollution.

ECOSTP Technologies has been recognised under the Startup India initiative and received appreciation from Prime Minister Narendra Modi. The company also received the Most Circular Economy Business Innovator Award and has been acknowledged for promoting sustainable and circular economy practices.

Wait, is this for real? A cow's stomach? That's actually amazing! I've seen our rivers in Tamil Nadu getting so polluted - this gives me hope. But we need these solutions to be cheap enough for villages to actually use them. The startup angle is good but let's see how scalable it is. Also, kudos to IIT Jammu for collaborating!

This is the kind of 'jugaad' innovation that makes me proud to be Indian. Using biomimicry to solve our water crisis? Brilliant! We treat less than 20% of sewage, which is criminal for a country that worships rivers. But I'm cautiously optimistic - many desi startups fail to scale. Hope ECOSTP gets more institutional support. And yes, PM Modi's appreciation is a good sign! 👏

Impressive that they've already treated 9 billion liters across 24 states! But let's be honest - India's water problem is massive. We need thousands of such plants, not hundreds. Also, what about maintenance in remote areas? The no-electricity claim sounds great but I wonder how weatherproof these underground chambers are. Still, a big step forward! 💧

I work in water management in rural Maharashtra and this gives me hope. Our existing STPs (sewage treatment plants) cost crores to run with electricity bills! If this gravity-based system truly works without power, it could revolutionize sanitation in villages. However, I'd like to see more independent studies on water quality results. The 'cow stomach' concept is unique but proper testing is crucial. Good effort though!
