'After reviewing all the information, officials from the central government, and the UNICEF, and WHO team lauded the entire process of purifying and distributing water to Delhi residents by the DJB. They also commended the procedures followed in all of DJB's testing labs,' said the officials. Bharadwaj said that officials from the central government and the UNICEF, and WHO team wanted to understand how DJB ensures the availability of clean water to the people of Delhi on such a massive scale.

Bharadwaj also shared that approximately 10,000 kilometers of water pipelines have been laid in Delhi. 'These pipelines ensure that water reaches almost every colony in Delhi. In cases where some areas are yet to be connected, the Delhi Jal Board is actively working on extending the pipelines to those areas,' he said. /IANS
