Out of its 103 drainage basins, those underneath in the dry zone were successfully irrigated through system of tanks and diversion canals. Sociotechnical aspects of water management seem efficient and well performed in the construction and maintenance of these tank and canal systems. It is believed that the king and the regional chieftains perform very strong tight management. In addition strategic use of both top-down and bottom-up initiatives as well as private partnerships with their own tanks and maintenance systems were supported for the efficient maintenance and management. Though there are a number of contradictory points affecting the different ethnic and religious groups, the Dublin principles have been used at various decision-making stages by the present governments. However, the current political, economic and technical performances are not geared enough for such efficient water management. The religious, ethical and moral aspects interwove with the ancient civilization, were the basis for maintenance and management of the hydraulic systems and subsequent upheaval in the society. Therefore, we argued that for successful water resources development programs need community engagement, sound technology and timely resources.
