40. Any officers or persons authorised in that behalf by the Board may enter at any reasonable time during the day or night, and inspect any premises where they have ground for believing that any person has recently suffered from or died of any such disease, or that necessity may otherwise exist, for executing in relation to such premises any of such Bye-Laws.
41. When any such Proclamation is in force, and upon any evidence that the Board may deem sufficient that any premises are so overcrowded, as to be injurious to health, the Board shall have power to make such Order as it shall see fit to abate such overcrowding, and the house-holder, tenant, or occupier of such premises who shall permit such overcrowding to continue after such Order shall have been served on him shall forfeit a sum not exceeding one hundred dollars for every day during which such overcrowding shall continue, and in default of payment he shall be liable to imprisonment for any period not exceeding three months.
42. All Proclamations of the Governor in Council for executing the provisions contained in Sections 35 to 40 of this Ordinance, both inclusive, shall extend to the waters of the Colony, and the Board may issue under the said Proclamations, by virtue of the provisions of Section 36, Bye-Laws for vacating, cleansing, purifying and ventilating vessels.
PART III.
43. Every owner of a new building erected within the City of Victoria shall' construct the ground floor of such building at such sufficiently high level as will allow of the construction of a drain and of the provision of the requisite communication with any public sewer into which such drain may lawfully empty; at a point in the upper half-diameter
of such sewer.
44. Every owner of a new building within the City of Victoria, shall, in the construction of every drain of such building, use good sound pipes formed of cast iron jointed with lead or hard, well glazed stone-ware socketted pipes jointed water-tight in cement mortar composed of at least one part of good cement to three equal parts of clean sand. Black bricks shall not be used in the construction of any house-drains intended for the conveyance of sewage.
Red bricks may be used, provided they are hard and sound, and that they are set in cement mortar of the foregoing description, and that the interior surface of the drain is also sinoothly rendered with the same mortar.
45. Every owner shall cause every such drain to be of adequate size, such size to be approved by the Board, and in no case to be less than four inches internal diameter. Where the ground is soft, such drain shall be laid in a bed of good lime concrete. Every house-drain shall be laid with a proper fall to the satisfaction of the Board.
46. No drain shall be so constructed as to pass under any building, except in any case where any other mode or construction may be impracticable. Any drain passing under a building shall be laid in one straight line for the whole distance beneath such building, and shall be com- pletely embedded and encased all round in good and solid lime concrete, at least four inches thick all round.
pro-
47. Adequate disconnexion and ventilation shall be vided at the end of every house-drain, by means of gully- traps, with slop-stone covers or suitable iron perforated covers or gratings, and ventilating pipes, placed at such points and levels, and in such manner as shall in each case be required by the Board, and every inlet to every house- drain, shall be properly trapped and shall be grated, or covered with a perforated stone or iron cover that shall effectually prevent the introduction of any solid substance into such inlet and the perforations or apertures of every such grating or cover, shall be of not less than the sectional area of the pipe or drain to which it is fitted.
48. Every drain from a building communicating directly with, any public sewer, shall be provided with a suitable trap, ventilating-grating, disconnecting manhole, or other appliance, to the satisfaction of the Board, at such point between such building and such public sewer as shall be pointed out in each case by the Board.
49. No house-drains shall be joined in such a manner as to form any right-angled junction, either vertical or hori- zontal. Every drain shall join another drain obliquely in the direction of the flow of such drain.
