A negative carbon footprint natural biological system water solution: evidence from Delhi, India.

Delhi's need for pure water is growing with its growing population. Along with the need for drinking water, useful sewage treatment is much needed. Another immense problem that the city faces is air pollution that causes health problems to the local community mainly caused by energy traditional plants. The patent Natural Biological System (NBS) developed by Ayala Water and Ecology offered Delhi and many other locations around the globe a practical, on-site method for the simultaneous purification of soil, water, and air with a negative carbon footprint. The current paper describes how those systems were applied to the on-ground situation after an extensive environmental survey that was conducted to identify the needs and difficulties characterizing the city. The solutions provided to Delhi are an example of how urban eras can benefit from the NBS system improving their ecosystem and supporting better and healthier life for their residents.
