A decision has been taken to install CCTV cameras on several bridges from Hanwella to Peliyagoda to identify and arrest persons who dispose waste into the Kelani River.
Nets will also be set up under bridges to prevent garbage from falling into the river.
The Kelani River has been identified as the most polluted river of the 103-river system in the country.
According to a survey conducted by the Central Environmental Authority of the country’s river system, 10,733 places have been identified as areas from which waste is being disposed to rivers.
1,374 such waste disposal sites have been identified along the Kelani River alone, including 797 in the Colombo city and 577 in the Gampaha district.
80 percent of the drinking water requirement in the Colombo District is met through the Kelani River while certain factories and individuals disposing garbage has led to complete pollution of the river.
The Ministry of Environment said waste from factories, especially in the Seethawaka and Biyagama industrial zones, enters the Kelani River.
