Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Delhi, the capital of India located in northern India, has a population of over 13.9 million at present and It has grown by more than 300% since 1971 and expected to increase 23 million by 2021 at a growth rate to 26.4% and expected population by the year 2050 is projected to be 72 million at a growth rate of 44% .The decadal water requirement and wastewater generation as projected in the master plan of Delhi development authority would be in order of 6674, 5340 MLD in 2011, 8365, 6692 MLD in 2021 and 19728, 17750 MLD in 2050. Delhi alone produces nearly 600MGD of sewage on daily basis and the installed capacity of wastewater treatment plants has the capacity to treat only 512.4 MGD, out of which nearly 58% of total sewage i.e. 3296 MLD approx. of the sewage generated is dumped into river Yamuna directly or indirectly. Central pollution control board reported that the cumulative assessment of all the parameters of water quality as mentioned by the CPHEEO indicates that Yamuna is not conforming to the desired level and more or less resemble a drain, also on the basis of the information collected on the inspection of Yamuna it is reported that the river does not have fresh water. There are 30 Sewage treatment plants but they are in non-functional and underutilized condition to the extent of 37%, only 63%of the sewage treatment plant is operational at present. This paper presents the study done on the water demand, wastewater generation and treatment status of the national capital of India.
