Quality of Drinking Water in Delhi
Delhi Jal Board (DJB) has informed that water being supplied in Delhi is potable and meets the prescribed quality parameters as per BIS 10500-2003 standards. Test Report for the period January 2012 to August, 2012 for the water samples collected and tested from all parts of the city confirmed that water being supplied by DJB is potable and free from contaminants.

DJB has also informed that for ensuring that water supplied to the citizens of Delhi is potable and meets the quality parameters as per standards of BIS 10500-2003, seven laboratories equipped with hi-tech laboratory equipments work round the clock at all the Water Treatment Plants to monitor water quality starting from intake of raw water to various stages of treatment and supplies to the areas. Apart from these seven laboratories at the plants, six Zonal laboratories are located in different parts of the city. Daily about 300-400 water samples are lifted from the consumers and tested in these zonal laboratories for Physical, Chemical and Bacteriological parameters for ensuring quality standards. DJB also gets its water tested through its National Scientific Agency, namely, National Environment Engineering Research Institute.These test results are regularly analyzed and in case any local contamination is found, corrective measures are immediately taken to ensure potable water supply to the consumers. Water sample test reports for the period from January 2012 to August, 2012 show that the percentage of unsatisfactory water samples is 2.56% which is well within the WHO norms of 5% limits.

This information was given by the Minister of State for Urban Development Shri Saugata Roy in a written reply to a question in Rajya Sabha today.
