Objective

●Sustainable Urban Water Management: The primary goal of the SAM model is to ensure the sustainable management of urban water resources in Hyderabad.

●Address Groundwater Issues: It aims to tackle persistent problems such as groundwater depletion and drying up of borewells.

●Prevent Urban Flooding: The project also seeks to mitigate the quick flooding of city streets during heavy rains.

Implementation Framework

●Pilot Project: The initiative is being implemented on a pilot basis under the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) scheme.

●Selection of Sites: Five municipal parks have been identified for the pilot. The initial focus is on two parks in the LB Nagar zone: Kakatiya Park at Habsiguda and E-sector park at Sainikpuri.

Nodal Agency

●National Institute of Urban Affairs (NIUA): NIUA is the nodal agency responsible for overseeing the implementation of the SAM model.

Technical Approach

• Shallow Water Injection Borewells: The project involves drilling borewells to a depth of 100-120 feet to inject water into the shallow aquifers.
• Recharge Pits: Water collected from the surrounding watershed is channelled through recharge pits to facilitate the recharging of underground water layers.
• Rainfall Utilization: The system ensures that rainfall is effectively used to recharge groundwater, thereby raising the water table.     

Expected Outcomes

●Groundwater Recharge: The recharging of shallow aquifers will help in increasing the groundwater levels in the targeted areas.

●Technical Benefits: The project is expected to recharge groundwater aquifers in the surrounding areas and soon see an improvement in groundwater levels.

●Sustainable Water Management: The initiative aims to create a sustainable framework for urban water management that can be replicated in other regions.

●Flood Mitigation: By efficiently managing rainwater, the project will help in reducing urban flooding.

●Scalability: If successful, the SAM model could be scaled up and implemented in other parts of Hyderabad and potentially in other cities facing similar water management issues.

●Policy Integration: The project aligns with broader urban development and sustainability goals under the AMRUT scheme and other national policies.
