It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The term "sembawang hot spring" does not seem to be associated with any maintenance or infrastructure issues in public housing. It is possible that the user simply mentioned the location as a point of interest or a place they visited.
