Delhi Jal Board — misbehavior

Address:

Rajender Nagar N.delhi-110060 -110060, New Delhi, Delhi, 110060

Am resident of old rajinder nagar block 3, first and foremost the j. E out here is since last more than 15 years - is this a permanent area or transferable?
Secondly were getting normal water supply but since last two days once again are getting contaminated water, upon contacting je got a very rude answer. How come mr. Kejriwal claims 24×7 water supply?
Will appreciate a feed back, am filing a rti also.
