Hero of a sustainable lifestyle
Many of us just keep cribbing about the atmosphere around us and do nothing about it. Some like Pritam Kumar Sinha a sustainable lifestyle showing us a path to do so ourselves.
An Ex-infosys, Professor of Practice, Multidisciplinary Research, Bangalore University and Advisor - Centre for Smart Governance, Department of Personal and Administrative Reforms, e-governance, Government of Karnataka, Mr Pritam Kumar Sinha is a master in many areas. He shares his journey with us.
For over a decade, I have been living in a rural area at border of Bannerghatta Forest, at the outskirts of Bangalore City where access to safe drinking water has been a constant struggle, as the RDPR has not provided water supply as per rules and regulations to developed layouts under its jurisdiction despite BMRDA, UDD approvals.
Over the years, I have experimented extensively with water conservation, wastewater management, and rainwater harvesting, facing repeated setbacks, from sediment buildup to aerator chokings caused by dust accumulation on roof in rainwater.
After years of trial and error, I am delighted to have finally achieved a solution that ensures water security for most months of the year.
We have developed a low cost three-layer five microns rainwater filtration design that effectively eliminates sediment accumulation and improves water purity.
The excess rainfall collected in our 30,000-litre sump is now directed to a recharge well, contributing to groundwater replenishment.
In addition, purification of washing machine waste water, kitchen waste water and RO water has helped to achieve water security in absence of water supply by RDPR.
There is need for a citizens-driven initiative through passionate effort, innovation, and persistence, without dependency on grants, external funding, or government schemes.
Unless water purification and conservation are ensured at the source itself, the broader water crisis will only persist. Such steps would help for river and lake rejuvenation without need of any external funding etc.
Comparing last year’s electricity bills with this month’s, I am delighted to share that the low cost off-grid solar system has brought about an incredible 90% reduction in my power expenses from 5.5K a month in September 2024 to less than INR 500 in October 2025!
It’s truly amazing to see how harnessing the sun’s energy so effectively has drastically cut my dependence on the grid.
Not only am I saving substantially on electricity costs, but I’m also embracing a greener, more sustainable lifestyle with the freedom of reliable, clean power.
This journey into solar has been deeply rewarding and encouraging for a brighter energy future!
A wonderful inspiring journey indeed, We all can take a leaf out of his book.
