Bangalore Water Supply & Sewerage Board [Bwssb] — I'm complaining about borewell water in my area irregular

Hi in my area irregular of water supply at least 15 days in a month they don't give supply and monthly twice they collect money by bluffing telling that motor is not working or need to put new motor. Our tenants fight with us due to this i kindly request to do the needful as we are suffering like hell. We are depending only on tanker water which costs 400 pls help us.
Thank you
