Sri Lanka’s climatic conditions made such developments essential. The island receives abundant rainfall during monsoon months, yet extended dry periods can severely limit crop production. Without storage systems, excess rainwater would quickly drain away, leaving communities vulnerable to drought. Reservoirs like Pimburattewa were designed to capture and retain seasonal rainfall, ensuring that water remained available long after the rains had passed. This strategic storage capability stabilized agricultural cycles and reduced the risks associated with unpredictable weather.
