Efficiency of Water Treatment Plant in Tlawng River, Aizawl, Mizoram

The current study investigated the water quality of the Tlawng river for a year (February 2022 to January 2023), using both pre-treated and treated water samples. The Tlawng river is an important river since the population of Mizoram’s capital city, Aizawl, rely heavily on its flow for drinking water. The water physico-chemical parameters were compared with standards established by World Health Organization (WHO), the Indian Council of Medical Research (ICMR), the Bureau of Indian Standards (BIS), and the United States of Public Health (USPH). With an exception of DO and BOD in pre-treated water samples, all parameters measured during the study period were within acceptable limits.
