Orissa Integrated Sanitation Improvement Project in India

Orissa Water Supply and Sewerage Board (OWSSB)
Term of Project
2010 - Ongoing


In India, sewerage system is inadequate despite industrialization and rapid influx of population into urban area. As a result, untreated sewage has been released into rivers, causing serious river pollution and deterioration of living environment in urban area.
The state of Orissa, located in eastern part of India, has the highest poverty rate compared to other states in India.

In Bhubaneswar City, the state capital with the rapid population growth (from 220,000 persons in 1981 to 650,000 persons in 2001),has insufficient capacity of sewerage facilities which causes deteriorating sanitary conditions of local residents and bad water quality of surrounding rivers.

Cuttack City, which lies 25 km north of Bhubaneswar, flourished as the state capital until 1949 and remains the center of commercial activities in the state today, is located on the holms of Mahanadi River and Kathajodi River, are flooded in its low-lying areas during rainy season due to insufficient drainage facilities.
Same as Bhubaneswar, there is lack of sewerage system despite the rapid population growth.
