Rs. 50 million allocated to control algae bloom in the Diyawanna Reservoir

0 12
Occasional algae blooms in the Diyawanna reservoir cause extensive environmental damage to aquatic plants as well as aquatic species.
 
This algae bloom has occurred several times over the past decade due to increased phosphorus and nitrogen content in the Diyawanna reservoir water. Diyawanna Oya does not have a specific source of water and rain water supplies water to Diyawanna Reservoir through canals coming from various places. Nor does the water drain properly.
 
Therefore, on the instructions of His Excellency the President, the Minister of Environment Mahinda Amaraweera submitted a Cabinet Memorandum to appoint a Presidential Task Force to control algae growth in the Diyawanna Reservoir. With that approval, Dr. Anil Jasinghe, Secretary to the Ministry of Environment, was appointed as the Chairman of the Task Force.
 
The Presidential Task Force began investigations into the canals that carry water to the Diyawanna Reservoir in many times. Investigations have shown that algae growth is caused by increased sedimentation in the Diyawanna Reservoir and the accumulation of excess phosphorus and nitrogen.
 
Therefore, the Presidential Task Force comprising the Ministry of Environment, the Central Environmental Authority and the Urban Development Authority has initiated a special program to control algae growth in the Diyawanna.
 
Accordingly, a sum of Rs. 50 million has been allocated for the year 2022 under the Surakimu Ganga program on the instructions of the Minister of Environment to control algae growth in the Diyawanna Reservoir.
