Janapriya Engineers Syndicate — wrong connection of water connections in bathroom

I have one flat No. 7521, in Janapriya Nile Valley and facing a peculiar type of problem, in bath rooms there are two water connections one for flush and other for normal taps, here in one bathroom the connections have been interchanged, when both connections are operative then no problem but when flush water is closed and other is open then we are getting water in flush not in taps, when asked to maintenance people, the plumber is asking huge money, I heard that waste water treatment plant is going to be set up and after that this water will be supplied in flush connection, then we will get better water in flush and waste treated water in taps, how we will use that bathroom. The water supply has been resorted and we are getting water in flush connection. I request the Janapriya authorities to rectify this problem. The construction work in Nile Valley is in progress and the working force is available to rectify this problem.
