Water Resources of the State
Surface water resources
River Godavari in the north and Krishna in the south passes through Telangana. The Godavari Basin is situated between latitude 16°16' N and 22°43' N and longitude 73°26' E and 83°07' E in the Deccan Plateau. The basin is shared with States of Maharashtra, Karnataka, Madhya Pradesh, Chhattisgarh, Andhra Pradesh and Odisha as co riparian States. River Krishna is the second largest East flowing interstate river in peninsular India, draining into the Bay of Bengal. The basin is situated between East longitudes 73°21'00" to 81°09'00" and North latitudes 13°07'00" to 19°25'00" in the Deccan plateau. The basin is shared with States of Maharashtra, Karnataka and Andhra Pradesh as co riparian States. Apart from the major rivers, there are tributaries such as Bhima, Dindi, Kinnerasani, Manjeera, Manair, Penganga, Praanahita, Musi, Taliperu etc.
Ground Water Resources of the State
Groundwater is an important resource for crop irrigation, food production and industrial as well as domestic use for urban and rural area communities. Due to failure in monsoon and economic pressure on groundwater in the region increased fast, this resulted in deeper water levels. Throughout the past history, extremes of droughts and floods could adversely affect security of water supply with population growth have caused havoc on the ground water aquifer systems in these regions. About 75% of irrigation depends on Groundwater.
Water Projects of the State
Projects are classified based on the extent of irrigated ayacut (command area) under them: Major Projects, Medium Projects, and Minor Projects.

EFFECTS OF CLIMATE CHANGE ON WATER SECTOR
Although the impact of climate change on water resources has not been accurately quantified, various studies indicate that the likely impact of climate change on water resources could contribute to further intensification of the extreme events.
Further, the features of water resources – both the availability and the quality may also be considerably affected by the changes in the land use in the form of urbanization, industrialization and changes in the forest cover. Realizing that the various processes which influence the hydrologic cycle are of dynamic nature, precise quantification of the impact specifically due to climate change may not be a simple task and it would be necessary to make suitable assumptions at the initial stages.
INITIATIVES BY TELANGANA STATE GOVERNMENT
Government of Telangana has undertaken two very ambitious projects for addressing problems of drinking water and irrigation water supply problems which are Mission Bhageeratha and Mission Kakatiya respectively.
The objective of Mission Kakatiya is to enhance the development of agriculture based income for small and marginal farmers through restoration of 46,531 irrigation tanks. As on 13th March 2018, 16,606 tanks have been restored.

The Government of Telangana launched flagship program for providing drinking water at the door step of household by name “Intintiki Nalla” under ‘Mission Bhageeratha’ for the Urban and Rural areas of Telangana by instituting the Telangana Drinking Water Supply Corporation. Under the mission the policy of the Government is to provide drinking water in all the rural and urban areas by integrating the existing water supply systems in the rural and urban areas with the Grid proposed to be developed by TDWS Corporation. Telangana Drinking Water Supply Corporation has set out the following objectives.
1. To provide safe drinking water in all rural and urban areas in the state of Telangana by taking up drinking water supply projects to cater the needs of Rural and Urban people as per norms fixed by Government with all related infrastructure like laying of pipelines, approach roads, buildings, WTPs, electrical substations, Go downs, electrical lines, erection of pumping sets with electrical motors etc.
2. To develop, construct, erect, install sewerage systems and treatment plants in rural areas.
3. To supply bulk drinking water at entry point of the rural and urban areas and maintain the drinking water projects outside the GP / ULBs.
4. To fix, revise whenever necessary and to collect the tariff for the bulk drinking water supply as per the policy guidance of the Government.
Under the program the TDWS Corporation delivers water in bulk to the local bodies (urban and rural) which in turn has to be distributed by the local bodies. As such the intra town infrastructure required for integration with the grid followed by refurbishment / remodeling of the existing system including providing piped water supply to the extended /uncovered areas to cater to the prospective demand of the population (2033) has to be developed by the Public Health and Municipal Engineering Department as part of ‘Inti Intiki Nalla’ program.

INITIATIVES BY EPTRI
Environment Protection Training & Research Institute (EPTRI) is preparing the project “State Specific Action Plan (SSAP) for water sector for Telangana State”, in accordance with directions issued by Government of Telangana State & as per the ToR issued by National Water Mission, Ministry of Water resources, River Development & Ganga Rejuvenation, Government of India.
Goals of the project:
I. Comprehensive water data base in public domain and assessment of the impact of climate change on water resource,
II. Promotion of citizen and state actions for water conservation, augmentation and preservation.
III. Focused attention to vulnerable areas including over-exploited areas,
IV. Increasing water use efficiency by 20%, and
V. Promotion of basin level integrated water resources management.

EPRTI has submitted the Project Concept Note (PCN) on “Increasing climate resilience of urban water management system of Hyderabad” to Ministry of Environment, Forests & Climate Change (MoEF&CC) through NABARD for GCF funding. The objective of the project is to develop a climate resilient urban water management system for the city of Hyderabad to ensure a comprehensive long term climate resilient and sustainable management plan.
