No more than one house or building shall be supplied from one service connection. The Council, or the Building Inspector, when authorized to do so by the Council, may waive this requirement upon a finding that a separate service connection to any house or building is impracticable. Whenever two or more houses or buildings are supplied from one pipe connecting with a service main, each house, building or part thereof separately supplied shall have a separate stop box and a separate meter.
