This paper estimates the total freshwater demand by Indian thermal power plants (TPPs) and compares these with treated wastewater available at the state level. It highlights three scenarios: Waste Water (WW) availability from (I) current operational capacity of Sewage Treatment Plants (STPs) (II) current installed capacity of STPs; and (III) all the WW generated. These scenarios compare the demand-supply numbers for the 19 states, where freshwater (FW) based TPP is currently installed. Further, the paper also describes the implications of diverting WW towards industries from activities such as peri-urban agriculture. Finally, it highlights the significant impacts of using untreated sewage water, such as those on health, environment and productive activities.
Scenario 1: The water demand was compared against the total water available from the operational STPs.
Scenario 2: It analyses the states that would be able to support FW based TPPs if the entire installed capacity of STPs is made functional. Haryana is added to the list of states in Scenario 1.
Scenario 3: It is assumed that the entire sewage generated is being treated and used for running the TPPs. It emphasises on the states that would be able to support 100 per cent of TPPs dependant on FW.
