The discolouration has been attributed to the mixing of silt, clay, and sand washed in from soil erosion following heavy rainfall in Pillur dam’s catchment areas
A senior corporation official said, “Every year, the NTU would rise to 160 during monsoon, and the issue would be resolved in three or four days. But this year, sudden and heavy downpour led to intensified turbidity that has lasted for almost 10-15 days, which is unusual. As of today, raw water recorded 36 NTU, after treatment it reduced to 10 NTU.
