ORDINANCE No. 24 OF 1887.
Public Health.
Every house-drain shall be laid with a proper fall, to the satisfaction of the Board. [Repealed by Ordinance No. 26 of 1890.]
42. No drain shall be so constructed as to pass under any building, except in any case where any other mode of 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 completely embedded and encased all round in good and solid lime concrete at least four inches thick all round. [Repealed by Ordinance No. 26 of 1890.]
43. Adequate disconnexion and ventilation shall be provided 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. [Repealed by Ordinance No. 26 of 1890.]
44. 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. [Repealed by Ordinance No. 26 of 1890.]
45. No house-drains shall be joined in such a manner as to form any right-angled junction, either vertical or horizontal. Every drain shall join another obliquely in the direction of the flow of such drain. [Repealed by Ordinance No. 26 of 1890.]
46. No ventilating-pipe of any drain shall be of a less internal diameter than four inches, and such ventilating pipe shall, in every case, be securely fixed and carried up clear of the eaves or to such height, as shall effectually prevent any escape of foul air into any thoroughfare or building. [Repealed by Ordinance No. 26 of 1890.]
47. No overflow from any cistern or bath, or ablution, sullage, or refuse waters of any kind, nor the surface-drainage of any yard or back-yard shall be led from any building or premises through any down-pipe or open gutter into, or over any surface-channel of any public street, alley, thoroughfare, or other ground, nor shall such refuse waters be led into, or emptied over the surface of any back-yard, alley, or other ground belonging to such building, or premises, or other adjoining building or premises, but shall be conveyed in a watertight waste-pipe or down-pipe taken through an external wall, and discharged in the open air over a gully-trap covered with a grating, or granite slop-stone cover, and no such waste-pipe or down-pipe, shall be brought down any external wall or retaining wall, when such wall looks upon any public thoroughfare. [Repealed by Ord. No. 20 of 1890.]
