Green Technologies

From Clean Water to Solid Waste Management, GIWA helps implement green technologies that leave a positive impact on the environment and our lives.

Turning Sewage Points to Selfie Points

Every day, some 3 billion liters of sewage pollutes the Ganga River, home to 600 million people and countless species of flora and fauna. As a result, public and environmental health is suffering tremendously. In Varanasi alone, some 68% of the people who use the Ganga’s water there will fall ill, primarily from fecal-borne disease.

It is thus a priority for the Government of India, and for GIWA, to investigate and install effective and novel new technologies for ensuring sewage and drinking water from rivers, lakes and other sources no longer mix… therefore turning polluted environments pristine, transforming “Sewage Points” into “Selfie Points.”

Among these technologies under study and implementation by GIWA are GeoTube systems, which quickly purify drains and other sources of pollution from contaminants, leaving clean water as a result. GIWA is also investigating micro Sewage Treatment Plants, which treat sewage on-site while requiring very little land.

Clean Water Technologies

Countless thousands of men, women and children in India don’t have access to clean, healthy drinking water, leading to the nation having the highest rate of children suffering from stunted growth and very high rates of many other preventable illnesses. In times of disaster, matters worsen as populations risk suffering from deadly diseases from highly-contaminated water.

For these reasons, GIWA provides a targeted drinking water programme, which includes the provision of cutting edge technologies that are replacing RO public water purifiers across India.  GIWA is also bringing in low-tech solutions, such as bio-sand water filters for schools and other water cleaning technologies. In times of emergency, sanitizing tablets and portable water filters are rolled out to address immediate and short term needs.

Waste to Wealth


Ending Solid Waste Mismanagement

Rishikesh’s first Waste to Wealth technology, the Kill Waste, Fuel Free Solid Waste Disposal System was inaugurated by GIWA alongside the Hon’ble Chief Minister of Uttarakhand Shri Trivendra Singh Rawat.

This Kill Waste Solid Waste system is different from conventional incinerators in that it requires minimum investment, utilizes no fuel, has no maintenance, requires no technicians and uses simple equipment. The machine effectively disposes of dry and wet waste without odor and harmful gas. The output of kill waste is neutral ash, which has been neutralized by activated charcoal, which can be used as fertilizer.


Eco-Friendly Public and School Bio- Toilets

While toilets are crucial for community health, the handling of the resulting sewage can present a conundrum. Conventional sewage treatment plants are too expensive for most communities in the developing world, and require constant electricity, which is often unavailable or unreliable even in large municipalities such as Delhi. The widely-used alternative of pit-based latrines, including those that compost human waste, require labor-intensive mucking, which can, in some cases, result in the transmission of disease and other problems.

For these reasons, GIWA works with organizations such as India’s Department of Defense Research Organisation (DRDO) to introduce new toilet technologies, such as Bio-Digester toilets, to schools and public places. In such a way, communities can be introduced to new advances in sanitation and all may benefit from improved access to toilets.
