Dilmah Conservation established a programme in Delft in hopes of remedying issues relating to the inadequacy of drinking water which is affecting both the island's residents and its diminishing wild horse population.
Located on the Palk Straight, 10 km southwest of Jaffna, Delft (also known as Neduntivu or the Long Island) is the second largest of Sri Lanka's islands with a history spanning over a thousand years.
Delft's history and heritage was especially influenced by Ceylon's relationships with Portuguese, Dutch and British colonists since the 16th century. Utilized as a ground for rearing cattle and horses, the island was first described as Ilha das Vacas or Island of Cows and then as Ilha das Cavallos or Island of Horses. Even today, the island is famously known for its extraordinary population of wild horses.
Delft is home to a largely Christian and Hindu Tamil community of about 5,000 people who principally engage in fishing, producing dried fish, rearing cattle and poultry, and cottage industries centered on Palmyra products.
