Introduction

The Omanthai area reservoirs, located north of Vavuniya town, are a cluster of irrigation tanks that sustain farming communities in the dry zone. Surrounded by paddy fields, villages, and forest patches, these reservoirs not only provide water for agriculture but also serve as peaceful natural attractions.

History & Background

• Like many tanks in northern Sri Lanka, the Omanthai reservoirs trace their roots to ancient irrigation systems developed during the Anuradhapura and later kingdoms.
• The reservoirs were vital for paddy cultivation in this dry and arid region.
