Water supply related issues

I stay in apartment at sreekariyam which has (Kerala) Water Authority pipeline and is a primary source ofWater. For the past two weeks, we are facing water scarcity. The houses around our building is receiving uninterrupted water supply. When we question the Water Authority about this, we were able to understand that the valve that supplies water to our building and nearby building is turned off. They are saying that as per schedule the building would receive Water supply, for three days per week. Earlier, the water supply would be turned off on Friday evening and would come back on Monday early morning. I feel that flats are being targeted so that they order tankers to meet Water requirements, has anyone else faced a similar issue? What can be done about it?
