An Indian entrepreneur has made a zero-strength, zero-chemical program of wastewater therapy, and true to the traditions of the sub-continent, he employed character as an inspiration—specifically Hinduism’s most sacred animal.
In Bengaluru, a 54-calendar year-previous IT protection professional was residing rather in a luxurious gated community attained immediately after a extensive successful profession, but he determined to put all he experienced achieved on the line in excess of a simple clogged drain.
Tharun Kumar began to imagine techniques to construct a greater sewage treatment method approach that could create great excellent drinking water devoid of chemical compounds. The close by Varthur Lake was the perfect case in point of the will need for innovation in this spot, as the lake has for years been well-known for pollution.
In 2017, Kumar begun ECOSTP with the chambered tummy of the cow as his “bovine inspiration.”
Like all ruminants, cows have a 4-chamber stomach, in which the vegetation they take in are broken down by anaerobic microbes. If we remember significant college biology or PA courses, anaerobic means metabolism without oxygen.
Common wastewater crops use aerobic bacteria, or metabolic process with oxygen, to split down sewage, but this necessitates the ventilation process that constantly operates on electrical power. Common sewage treatment method also tends to use chemical substances, and has the presence of a total-time worker. Kumar has eliminated almost all of these downsides.
At the foundation of the ECOSTP septic tank is a layer of cow dung that offers the bacterial employees. With the h2o going via gravity, it enters the 2nd bacterial chamber right before passing into the 3rd place which is a filter of sand and gravel. The fourth chamber lies beneath a back garden of pick vascular vegetation which eliminates suspended solids, pathogens, nitrogen, and phosphorus, the latter two heading to feed the plants.

The ensuing h2o is graded by overall health inspectors as fantastic high quality for bathroom drinking water and gardening apps. With the aid of a grant from the US-centered Biomimicry Answers, ECOSTP now has 325 purchasers throughout 22 states in India, and their septic tanks are unmanned and unpowered, saving 1000’s in managing costs.
“My team and I measure ourselves by three metrics,” Kumar instructed India Today’s Ajay Sukumaran. “How much lousy water did we convert to excellent drinking water? How much electrical power did we preserve compared to a standard STP? And how substantially coal we saved, due to the fact 70 % of India’s electric power comes from coal.”

“We are very pleased to have reclaimed 2 billion liters of sewage so far with no electrical power or substances.”
ECOSTP is now seeing if it’s doable to determine anaerobic micro organism that can take away the harmful compounds of industrial effluent.
