Water contamination is not a new problem to Sri Lanka as people have already undergone such problems in the recent past in Rathupaswala, Jaffna and most recently in Kelaniya. Colombo and its suburbs experienced a water-cut on August, 17 due to the contamination of Kelani River water with around 1,900 liters of diesel leaked by the Coca-Cola Beverages into the Kelani River...Despite the fact that measures were taken to purify the Kelani River water, people in the area complained that there is still some content of oil left in the water. A considerable number of people who have been using only river water for their domestic usage and for consumption are still affected by the incident...Most of the factories in Sri Lanka do not adhere to the law in disposing their waste materials which cause the water pollution in both the ways.
