Delhi Jal Board — water having foul smell

Address:

Mansarovar garden, New Delhi, Delhi

Dear sir/madam,
This is to inform you that the supply water in mansarovar garden near indian overseas bank ring road marble market is having very foul smell we get stomach cramps and fall ill very frequently. The supply water that we receive is sometimes black in color and smells like gutter water. I would request you to kindly take this on a serious note.
