Delhi Jal Board — Water supply in morning

I am a resident of India staying in 110008. From the past 2 months we are facing the problem of water supply in our area, earlier water supply timings were 4:30 Am to 5:30 am

Since past 2 months now the water starts coming at 4:30 am and goes off by 5:00, then again starts at 6 am and comes only for 15 minutes.

From the past 1 week now water comes at 4:45 am and goes off by 5:05 am. I request you atleast give us a 1.5 hour water supply daily so that atleast our tanks could get full.
