Japan’s JFE Engineering on Monday announced that it has received an order for the design and construction of a wastewater treatment plant and treated effluent disposal system in Sri Lanka’s central hill capital of Kandy.
The order from the Sri Lankan National Water Supply and Drainage Board under the Kandy City Wastewater Management Project will be for the design and construction of awaste water treatment plant, main pump station, treated effluent disposal system, sludge drying beds and supply of operation and maintenance equipment.
It is the first project for the construction of a sewage treatment plant funded by the Japanese Government’s Official Development Assistance (ODA) program, the Tokyo-based company said in a release.
The company notes that despite a rapid economic growth in recent years, the sewerage system in Sri Lanka has not been able to keep pace and its coverage is still limited to approximately 2.5%.
Even in Kandy, the country’s second largest city and registered as a UNESCO World Heritage site, the household wastewater is still discharged directly into rivers and lakes without adequate treatment which is causing deterioration in the water quality.
The facility will treat sewage from approximately 70,000 city residents which will lead to an improvement of the water quality of rivers and lakes, particularly the Mahaweli River, one of the main water sources in the country.
With a capacity of 14,000m3/day, the proposed plant utilises 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.
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 reduce plant operation costs, which will be borne by the client after construction.
“Following the completion of this project, which aims to improve the environmental management in the beautiful ancient city of Kandy, JFE Engineering will continue with its long-standing commitment to contribute to Sri Lanka’s economic development through the supply of its products and technologies, such as bridge structures, waste to energy plants, among others,” the company said.
