Karamana River Scientific Management  - Pilot Project

Rivers Worldwide are polluted due to anthropogenic activities. Many countries have understood the impact of river pollution on living things & environment and adopted scientific methods to mitigate pollution and succeeded sustainably.

The objective of KRSM (Pilot) Project is to develop and implement a comprehensive model action plan for the scientific management of Karamana- Killi River in the city area with the idea of copying the success story to other rivers also.

This special project is co-ordinated by KSCTSE, monitored & implemented by TRIDA and executed through line Departments & Institutions with people’s support and involvement. Government have constituted a Co-ordination Committee, an Implementation Committee and a Technical Committee for advice and guidance of the project. The project started in 2013-14 and is continuing. About fifteen subprojects had been competed, and three are in the completion stage. After assessing the progress of the pilot project, it has been decided to wind up the pilot project and take it to a larger scale at a higher level to achieve the goal of clean Karamana - Killi River from the origin to the end. Hence, KRSM (Pilot) Project is in completion mode. The entire funding is by the State Government. Thrust is given to development of infrastructural items which have direct impact on pollution mitigation of the river. Emphasis is also given for awareness and people’s involvement in the project.
