Waste water treatment plant construction will be commenced in Kandy ceremonially tomorrow with the participation of City Planning and Water Supply Minister Rauff Hakeem, Japan International Cooperation Agency (JICA) Sri Lanka office Chief Representative Kiyoshi Amada, Central Province Governor Surangani Ellawala, Central Province Chief Minister Sarath Ekanayake and KMC Mayor Sena Dissanayake. The senior officials of the ministry and National Water Supply and Drainage Board will also grace this occasion.  

The old capital of Sri Lanka receives tourists from all over the country and abroad. As a World Heritage site and being second largest city of Sri Lanka, Kandy is famous for its beauty. Behind the beauty of the city, hidden are polluted canals and rivers, as Kandy city does not have modern sewerage system. The rate of deteriorating quality of water in rivers and the lake has increased with the increase of population, their activities, and use of water. Presently the city could accommodate 110,000 permanent residents while receiving 150,000 commuters daily and therefore waste water management system is a long-pending requirement and now become an urgent need. 

The proposed waste water management system aims to tackle these issues altogether. As sewerage treatment plant is installed, it is expected to improve water quality of Mahaweli River, one of the major water sources in the country. Improvement of its water quality in upper stream will have positive impact for downstream areas. The project is being managed by National Water Supply and Drainage Board. JICA is financing for the project under highly concessional loan amounting 14,087 million yens (equivalent to Rs.16,900 million). 

The proposed waste water treatment plant under Package-1 of the project with a capacity of 14,000m3/day utilizes the Propeller-type Oxidation Ditch (OD) System, which enables the efficient treatment of sewage through the high mixture with oxygen promoted by submersible propellers and air diffusers in the Aeration Tank. Japanese company, JFE Engineering Corporation, with unparalleled experience in Japan providing facilities with this technology, actively proposed this system to the Sri Lankan government in order to help for reducing plant operation costs, which will be borne by the client after construction.

The project will also provide improved sanitation in densely populated and low-income areas in Kandy, through instalment of in-house sanitation facility, and refurbishing public facilities. Introduction of improved sanitation will improve sanitary environment of community and improve health condition of the residents. 

JICA continuously supports the Sri Lankan government for management of its sewerage problem. At the moment, a team of Japanese experts is working with the National Water Supply and Drainage Board preparing of an islandwide master plan for sewerage sector in Sri Lanka, said Amada.
