Case Study of the Day: Water secured district of Tamil Nadu: Namakkal

Introduction

Namakkal district is located in the southwest of Tamil Nadu, India. It has a population of about 1.7 million people and is largely agricultural. The district has been facing water scarcity for many years, but in recent years, it has taken a number of steps to become water secure.

Implementation

One of the most important steps that Namakkal district took was to implement a comprehensive water conservation and management plan. This plan involved a number of different initiatives, including:

• Rainwater harvesting: Rooftop rainwater harvesting systems were installed in homes, schools, and other buildings. Percolation tanks were also constructed to store rainwater and recharge the groundwater table.
• Check dams: Check dams were built across rivers and streams to slow down the flow of water and allow it to seep into the ground.
• Afforestation: Trees were planted along riverbanks and other water bodies to help prevent soil erosion and improve water infiltration.
• Efficient irrigation practices: Farmers were encouraged to adopt more efficient irrigation practices, such as drip irrigation.
• Water auditing: The district government conducted water audits to identify areas where water was being wasted.

Outcome

These initiatives have helped to improve the water situation in Namakkal district significantly. The groundwater table has risen, and the number of water scarcity days has decreased. The district has also become a model for other parts of India that are facing water scarcity.

Key lessons that can be learned from Namakkal district’s experience:

• A comprehensive approach to water conservation and management is essential.
• Community participation is essential for the success of any water conservation and management program.
• Government support is also essential.

Namakkal district’s experience shows that it is possible to become water secure even in areas that are facing water scarcity. By implementing a comprehensive water conservation and management plan and involving the community, Namakkal district has been able to improve its water situation significantly. This is a model that can be replicated in other parts of India and the world.
