ITEM in THe ISLAND, March 2026, entitled  “Lanka discovers largest groundwater source”

The National Water Supply and Drainage Board (NWSDB) on Friday said the largest groundwater source discovered in Sri Lanka so far had been identified during tube-well drilling near the Pitabeddara Police Station.

Indrajith Gamage, geologist in charge of the Southern Province, said the source recorded a continuous flow of about 10,000 litres (10 cubic metres) per minute, marking the first instance in the country where a groundwater source of that magnitude had been found. He noted that the previous largest groundwater source was discovered in the Madhu area, which recorded a flow of about 7,000 litres per minute.

According to the NWSDB, the tube well was drilled following geological studies of rock layers and the identification of underground water through fractures in rock strata using specialised technical instruments.

The Board said steps would be taken to distribute water from the newly discovered source to residents facing shortages in Pitabeddara, Morawaka and surrounding areas.
