How an Engineer from Maharashtra Is Recycling 1.25 Lakh Litres of Greywater Every Day in Urban Homes
Water scarcity is no longer a distant crisis—it’s knocking at the doors of India’s biggest cities. But one man, Abhijit Sathe, an engineer from Maharashtra, is proving that smart greywater recycling can bring about meaningful change. Through his company JalSevak, Abhijit is helping housing societies and commercial complexes reuse an astounding 1.25 lakh litres of greywater every single day.
Growing up in the parched districts of Maharashtra, Abhijit saw firsthand the devastating effects of water shortage. With this lived experience, he chose to channel his engineering expertise into creating solutions for urban water conservation. This gave birth to JalSevak, a social impact-driven startup focused on treating and recycling greywater—the water discarded from sinks, showers, and laundry—that usually goes to waste.
JalSevak installs custom greywater recycling units in apartment complexes and buildings. These systems filter out impurities through multi-stage bio and mechanical filtration techniques, making the water fit for non-potable uses such as toilet flushing, gardening, floor cleaning, and car washing.
Not only does this reduce fresh water consumption by nearly 40%, it also cuts water bills drastically for residents and reduces burden on municipal water supply.
One of the most successful deployments is in a residential society in Pune, where JalSevak's system treats over 20,000 litres a day, saving lakhs of litres monthly. So far, the startup has implemented its systems across several cities including Mumbai, Pune, Bengaluru, and Hyderabad, collectively recycling over 1.25 lakh litres of greywater per day.
What makes JalSevak unique is its plug-and-play model, low maintenance, and compact design—ideal for retrofitting in old societies and scalable for large townships. Their team also offers regular audits, awareness workshops, and technical support to ensure optimal usage.
As water levels in major reservoirs continue to dip, solutions like JalSevak are a lifeline for India’s urban future. Abhijit Sathe’s story is a reminder that with vision and engineering, even waste water can be turned into liquid gold.
