Resident of Osborne road - Ulsoor,
There has been issue regarding water supply by the line men, he doesn't answer the phone call incase if attending also says will be supplying water after 8pm but end up with no water, upon meeting and asking he says will leave water only alternative days, what about we people with little sump with not much storage capacity, are we supposed to use water only alternative days and be without water for 2-3days in a week, our place is having major water issue, bwssb officials wake up, we are humans, we need water on daily basis not on alternative days, this is not happening we cannot suffer without water, kindly sort the issue
