Jaffna, Hikkaduwa, Anuradhapura landfills have the capacity to accommodate 50 tons of waste daily while Polonnaruwa landfill can accommodate about 20 tons daily and the life span of the landfills will be more than 10 years. The designing and planning of such landfills have been completed and the procurement process is under way. The project is scheduled to be completed by 2020.
