1. Any owner or occupier of private premises about to construct any new drain, shall give at least seven days' previous written Notice of such intention to the Board, and such Notice shall be delivered at the Office of the Board, in a form of which printed blank copies may be obtained gratis in English and Chinese on application at the Office of the Board, or in the case of the villages-at any Village Police Station, between the hours of 10 A.M. and 4 P.M.
2. Every such Notice shall specify the name of the Street, the number of the Lot and the number of the house if any, which it is intended to drain and shall be accompanied by a plan in duplicate of the premises drawn on a scale of not less than twenty feet to the inch, and such plan must show the whole of the new drains with their proposed sizes figured thereon, and a section or sections showing the proposed falls or inclination and drawn to the same scale and to a vertical scale of not less than ten feet to the inch. The plan must also show the position and course of all proposed surface gutters.
Except that in case of suburban lots which cannot be conveniently included within a plan of ordinary dimensions, when the lot and the out-fall drain may be shown on a scale of not less than one hundred feet to the inch.
3. Within seven days after receipt of the Notice, the Sanitary Surveyor shall, by means of a written communication, in English or Chinese as may be necessary, inform the person who has given the said Notice whether his designs and proposed mode of construction are approved or disapproved, and in case of disapproval such modifications or improvements as may be requisite in order to comply with the provisions of Ordinance No. 24 of 1887 and of any Bye-Laws made thereunder shall be indicated in detail to such person by the Sanitary Sur- veyor, and it shall not be lawful for such person to commence the new drains until the approval thereto of the Sanitary Surveyor shall have been previously obtained by him, and in the case of such approval one copy of the deposited plan shall be returned to him, and the remaining copy shall remain filed in the Office of the Sanitary Surveyor.
NOTE. The approval of plans conveyed by the Sanitary Surveyor under this bye-law certifies simply to the fact that the plans are in accordance with the Public Health Ordinance and with the bye-laws made thereunder but signifies no approval of the sufficiency or otherwise of the plan and throws no responsibility on the Board.
