Sri Lankaâ€™s second biggest city to get new sewerage plant
ECONOMYNEXT – Construction work begins on February 19 on a Japanese-funded waste water treatment facility for Sri Lanka’s second biggest city, the hill country town of Kandy, which would also improve water quality in its main river.
Japan International Cooperation Agency (JICA) said it is financing for the project under a highly concessional loan of 14,087 million yen (16.9 billion rupees).
The project is being managed by Sri Lanka’s National Water Supply and Drainage Board.
Kandy, a World Heritage site that receives tourists from all over the country and abroad, does not have a modern sewerage system and has polluted canals and rivers, a statement said.
“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,” it said.
Presently the city could accommodate 110,000 permanent residents while receiving 150,000 commuters daily, making the Waste Water Management System an urgent need.
The proposed sewerage treatment plant 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,” JICA said.
The proposed Waste Water Treatment Plant by the Japanese company, JFE Engineering Corporation, has a capacity of 14,000m3/day and uses the ‘Propeller-type Oxidation Ditch (OD) System’, JICA said.
This enables efficient treatment of sewage through the high mixture with oxygen promoted by submersible propellers and air diffusers in the aeration tank, it said.
The project will also provide improved sanitation in densely populated and low income areas in Kandy, through installment of in-house sanitation facility, and refurbishing of public facilities. (Colombo/Feb17/2016)
