No House or Building within the Limits of the special Act shall be built upon a lower Level than will allow of the Drainage of the Wash and Refuse of such House or Building into some Sewer belonging to the Commissioners either then existing or marked out upon the Map herein-before directed to be made by them, or into the Sea, or some public River into which the Commissioners are empowered to empty their Sewers; and if there be such Means of Drainage existing within One hundred Feet of such intended House or Building, the Commissioners shall cause a Drain leading thereunto from the intended Site of such House to be made of such Materials, of such Size, at such Level, and with such Fall, as they think fit, or if there be no such Means of Drainage within One hundred Feet of any Part of the said intended Site of such House or Building, then such Drain shall be made so as to lead into such covered Cesspool or other Place as the Commissioners direct, not being under any Dwelling House, and constructed to the Satisfaction of the Commissioners, so as effectually to prevent the Escape of the Contents thereof, until such Sewer as aforesaid is made by the Commissioners, when they shall make a Drain to communicate with such new-made Sewer, and shall demolish and fill up any such Cesspool.
