Water is one of the world's most valuable resources, yet it is under constant threat due to climate changes, resulting in drought, explosive population growth, and waste. India is completely dependent on the monsoons to meet its annual water demand. Reclamation and reuse of the Wastewater would help minimize the overall supply of water. The amount of non-potable water generated in the Class 1 Cities has a population of n more than 1 la, is approximately 35,558 Million liters/day. This water goes directly into the septic tanks and becomes Wastewater. SBT involves removing organic matter by adsorption, followed by biological degradation and oxygen supply by natural aeration to the treatment system. The photosynthetic activity of green cover serves as a bio-indicator for the kind of micro-habitat in SBT.
