Abstract
The earth’s water resources are limited. Less than 1% of this water is suitable for human consumption. Because of the rapid increase in population, there is an urgent need to conserve and reuse water. This study examines all water utilization methods, water demand and the current state of wastewater treatment in India’s most populous state, Uttar Pradesh. The current water supply system is incapable of meeting the demand. For a demand of 105.96 BCM, there is a supply of 77.99 BCM. The total amount of seepage waste generated is estimated to be 8263 MLD. In Uttar Pradesh, there are 107 STPs (operation and non-operational) that can treat 3370.87 MLD of water. The remainder of the waste is dumped into rivers or on open land, which harms the environment and exacerbates the problem of water pollution. In this paper, methods for treating wastewater (STP) in Uttar Pradesh are described and a comparative analysis of sewage generated, sewage treated and the number of STPs installed with their total capacity since 1989 is presented. The percentage increase in STP installed per decade is decreasing, as is the percentage increase in actual utilization capacity. These decreasing trends do not correspond to a rapidly growing population and industrialization which has resulted in more increase of wastewater generation. There is a need for more efficient water treatment methods and a greater number of STPs with high actual utilization capacity should be installed to address the issue of untreated sewage disposal. The reuse of treated wastewater for various purposes is also addressed.
