The Cholas were one of the most powerful and prosperous dynasties of South India during the medieval period. They were known for their military conquests, architectural marvels, and administrative skills. However, one of the most impressive achievements of the Cholas was their water management system, which is still evident in the form of huge tanks or reservoirs that they built to collect rainwater.



Water was a vital resource for the Cholas, as agriculture was the backbone of their economy. They needed water to irrigate their crops, especially during the dry seasons when monsoons were scarce. Therefore, the Cholas developed an elaborate system of tanks and canals to ensure a steady supply of water for their farms and households.



The Cholas constructed huge tanks or reservoirs to collect rainwater. These tanks were made of stone and were designed to store water for long periods. The tanks were interconnected by a network of canals and channels, which allowed the water to flow from one tank to another. The tanks were also equipped with sluice gates, which could be opened or closed to control the flow of water.



The Cholas' water management system had several benefits. Firstly, it helped to increase agricultural productivity by providing a reliable source of water for irrigation. This, in turn, led to higher crop yields and increased food production. Secondly, the tanks and canals also served as a means of transportation, as boats could be used to transport goods and people from one place to another. Lastly, the tanks and canals also helped to control floods and prevent soil erosion.



In conclusion, the Cholas' water management system was a testament to their engineering skills and their understanding of the importance of water as a resource. The tanks and canals that they built are still in use today and are a testament to the enduring legacy of the Cholas.

They used water harvesting method. It shows how agriculture plays a vital role in the growth of the chola empire. The rulers took interest in developing and improving irrigation facilities which improved production.
