ORDINANCE No. 24 OF 1887.
Public Health.
40. Rain-water shall be diverted from house-drains by means of surface channels or otherwise to the fullest extent practicable.
41. The rain-water from roofs, which slope towards enclosed court-yards, or back-yards, may, if diversion to the surface channel is impracticable, be received into the house-drain. But no ventilating pipe shall be used for the conveyance of rain-water from the roof.
42. No person shall, where it can possibly be avoided, lay any pipe for conveying sub-soil drainage in such manner or in such position as to communicate direct with any sewer, cess-pool or drain used for the conveyance or reception of sewage.
NOTE.-It is important to exclude sewage tainted air from the sub-soil. The connection of sub-soil drains to sewers even if a trap is used is objectionable, because in dry weather the flow of the drain may cease and the water or the trap may dry up and leave a free communication between the sewer and the sub-soil drain. The object of sub-soil drainage is not only the removal of water, but the aeration of the sub-soil. The mouths of such drains therefore should be so placed that pure air can enter freely, a condition incompatible with direct connection with sewers or house-drains.
43. In every case where the course of a new drain shall be diverted, any cesspool previously existing and into which such new drain may have previously emptied, shall be cleansed, deodorized and filled with clean earth.
44. All new drains or drainage works, shall be built and carried out in all respects in accordance with the provisions of Ordinance No. 24 of 1887 and of these bye-laws and of any that may be made hereafter and if no written notice as provided in bye-law No. 1 shall have been given to the Board by any person about to construct, reconstruct, alter or amend any new drain on his premises, and if by such default the Board shall have had no opportunity of inspecting and approving or disapproving of new drains actually built and already covered in, it shall be lawful for the Board on discovering the existence of such new drains or works to call upon the owner to open and uncover the same for the purpose of inspection and should such new drains or works prove upon inspection to be defective either in respect of design, workmanship or materials they shall be deemed a nuisance and dealt with as such.
45. All works connected with the construction of new drains and drain-connections shall be carried out in strict accordance with the plans and sections previously submitted to and approved by the Board, or with such amendments to such plans and sections as may have been required by the Board, and such works shall be carried out in a proper and workmanlike manner with the best materials of their respective kinds and shall be subject during their progress to the continuous control and supervision of the officers of the Board appointed in that behalf and shall be completed to the entire satisfaction of the Board.
46. These bye-laws shall come into force on and after the 1st day of January, 1891, and the bye-laws dated the 17th day of November, 1888, and published in the Government Gazette of the 24th November, 1888, are hereby repealed as from the 1st day of January, 1891.
