In Sangam‑era Tamilakam, clay vessels called “ māṇ paṇai ” or “kulam paṇai” were used to store and seep water near tree roots - especially for coconut, banana, and areca palms.

Effect of Municipal Sullage on the Bacteriological Quality of River Water-A Case study Environmental Risk Assessment 227-234 (1989) S.Manian, R.
