According to Agra Development Authority (ADA) secretary Prabhanshu Srivastava, NGT gave the order for collecting Rs 1.41 crore as penalty during a hearing yesterday.
It also ordered ADA to lay a pipeline to the sewage treatment plant at Jaganpur and said that the fine amount was to be utilised for that purpose.
The colonies and multi-storeyed buildings were found to be discharging sewage directly into the river via a pipeline.
The order in the case came upon a petition by environmentalist DK Joshi who said he had wanted to draw NGT's attention to the alleged uncontrolled construction on the river's floodplains in violation of existing legal provisions.
