DJB: Faecal coliform in Dwarka rainwater pits

A survey of rainwater harvesting pits in Dwarka's societies found that nearly two-thirds (65.3%) of all samples analysed had traces of faecal coliform, according to findings submitted to the National Green Tribunal (NGT) by Delhi Jal Board (DJB).

NEW DELHI:

Further, RWH pits in four societies were found to be non-functional, while the pit was found dry in 25 societies. This means that only 32 of the 176 samples, or 18% of all sites, did not contain faecal coliform matter.

DJB officials said directions have been issued to both the revenue department and the DPCC to initiate corrective actions and impose penalties.

The presence of faecal coliform bacteria indicates contamination of a waterway with the faecal material of humans or animals. As per the drinking water standards prescribed in IS 10500:2021, faecal coliform should not be detectable at all in a 100ml sample.
