Case Study- Mehrauli Community Sewage Pond, Punjab

Once a vital part of the local community, the Mehrauli Community Sewage Pond in Ropar District, Punjab, had gradually become polluted due to the continuous discharge of untreated wastewater. Poor water quality, persistent foul odours, and high microbial contamination had turned the pond into an environmental concern for nearby residents. To help restore the water body, Nanokriti deployed the NanoCloud N-50 Nanobubble Generator, introducing trillions of oxygen nanobubbles that naturally improved biological activity without the use of chemicals. The transformation was evident within just six weeks. Biochemical Oxygen Demand (BOD) dropped by 74%, Chemical Oxygen Demand (COD) was reduced by 82%, and E. coli contamination declined significantly, while the unpleasant odour disappeared and the water became visibly clearer. As the ecosystem recovered, fish and ducks were seen returning to the pond for the first time in years—a clear sign of improving environmental health. This project demonstrates how nanobubble technology can restore polluted community water bodies in a sustainable way, creating cleaner water, healthier ecosystems, and a better quality of life for surrounding communities.
