Let R be the number of water bottles Daniel refilled for the rugby team.
Daniel filled 11 * 6 = <<11*6=66>>66 bottles for the football team.
He filled 66 + 12 = <<66+12=78>>78 bottles for the lacrosse team.
He got water bottles for four teams, so the team coaches wanted 2 * 4 = <<2*4=8>>8 bottles.
In all, he filled 66 + 53 + 78 + 8 + R = R + 205 = 254 bottles in all.
Thus, he filled R = 254 - 205 = <<254-205=49>>49 bottles for the rugby team this season.
