MANAGEMENT OF WATER SUPPLY AND SEWERAGE SYSTEM IN HYDERABAD

摘要

Urban and regional water demand for freshwater in the capital city of Hyderabad in Telangana state has been increasing rapidly over the last few decades. Hyderabad with a population of about 9.5 million is moving towards attaining the status of a megacity; due to high rate of immigration, infrastructural developments, host for IT hubs and many illegal settlements. Meanwhile, the main water bodies in the city have been encroached upon by private and government agencies. In this scenario, the water demands for the residents are not met with reasonable standards. Earlier, Hussain Sagar Lake was the source of drinking water and now the entire Hyderabad city has been depending on the other sources viz., Osmansagar, Himayatsagar lakes as well as Manjira, Singoor, Krishna and Godavari River. At present, the Greater Hyderabad Municipal Corporation (GHMC) receives water of approximately 2068 MLD from these sources. On the other hand, drainage system is present only in some parts of the city and it is connected to Sewage Treatment Plants (STPs); But sewage remain directly released into the water bodies mainly Musi river without treatment through open drains. In this study an attempt is made to review, study and propose to have a good water supply distribution system, sewerage system and also storm water system in Hyderabad city to maintain the quality of water bodies and river Musi.
