About
About Kaveripakkam Eri (Tank) — Pallava Hydraulic Reservoir
One of the oldest continuously maintained Pallava-era eri (tank) systems in Tamil Nadu, 25 km south of Kanchipuram, built c.740 CE under Pallava Nandivarman II and expanded Chola Parantaka I c.950 CE. The Kaveripakkam Eri spans c.2.1×1.4 km (295 ha ayacut) with 5-m high earthen bund 6 km long revetted in laterite, sluice towers (tumpu) of Chola ashlar and British 1892 anicut feeder from the Kaveripakkam cut channel off the Palar. Udayendiram copper plates (750 CE) detail tank regulation and neerkatti water-man roles — a Tamil tank governance model still operative. The bund road and Neelakanteswara hill temple above illustrate Pallava irrigation–temple integration.
Why it mattersType-site for South Indian eri tank governance documented epigraphically since 740 CE, living tradition.
