Jan. 12.] THE NEW ZEALAND GAZETTE. 111

Board to perform the duties of the Secretary, whether designated as Acting-Secretary or not :

“Main sewer” means the main sewer now being or about to be constructed by the Board, and extending from the storage-tanks at Orakei to Oakley Creek, and any other main sewer connected therewith belonging to the Drainage Board :

“Local sewer” or sewers means any sewer or sewers constructed by or vested in one or more of the contributing bodies, but not being a main sewer constructed by or vested in the Drainage Board.

1. Every contributing body desiring to connect any of its sewers or drains with the main sewer shall send notice in writing of such intention to the Drainage Board, and shall attach to such notice complete plans and specifications of any sewer or sewers to be connected.

2. Such notice, plans, and specifications shall give full particulars of every local sewer or drain which by such proposed connection would convey sewage to the main sewer, and shall show the area and ultimate population such local sewers are intended to serve.

3. All plans shall include a general plan showing the line and direction of the local sewers to a scale of 200 ft. to an inch, a longitudinal section to a horizontal scale of 200 ft. to an inch, and a vertical scale of 20 ft. to an inch, on which shall be shown the surface of the ground, the invert levels of all local sewers at every change of grade, and the gradients of such sewers. All levels are to be indicated with reference to the Board’s datum, accurate information as to which can be obtained from the Engineer. Detail plans and sections of the manholes, lamp-holes, cesspits, and overflow-chambers, to a scale of not less than 4 ft. to an inch.

4. The specifications shall state clearly the materials to be used, and the method in which the work of constructing such sewers is proposed to be carried out.

5. No water-closet shall be connected to any sewer draining into any of the Board’s sewers, unless such closet is provided with a proper supply of water and adequate flushing-cistern of not less than 3 gallons capacity; but no water-closet shall be connected to any local sewer discharging into a main sewer until such time as the Drainage Board shall have notified the contributing body having control of such sewer that the Board is prepared to allow the contents of water-closets to be discharged from such local sewer into the Board’s sewers. This shall not apply to the sewers already connected with the Hobson Bay main sewer.

6. All openings in local sewers used for the admission of storm, surface, or subsoil water from streets, open places, private premises, &c., shall be provided with a proper cesspit and grating so designed as to effectively prevent the passage to the sewer of any rubbish, sand, grit, detritus, or other organic matter that would be likely to cause settlement and deposit in or injury to the Board’s sewers, tanks, appliances, &c.; and all such inlets or openings must be constructed and maintained by the contributing body to the approval of the Board’s Engineer. Such cesspits must be kept properly clean, and, failing this being done, it shall be lawful for the Engineer, after twenty-four hours’ written notice to the contributing body, to have the same properly cleaned, and to recover the cost of so doing from the contributing body.

7. No local sewers shall be connected to the main sewer until the Engineer has certified that such local sewer is in good order and condition, and is fit to be so connected; and in the case of a connection having been made prior to the completion of the local sewer, twenty-eight clear days’ notice shall be given by the contributing body to the Drainage Board before house connections are made, or any sewage, storm, surface, or subsoil water is allowed to run therein.

8. The actual connection between any local sewer and the main sewer shall be controlled by a proper overflow-chamber so constructed as to insure that the quantity of sewage or liquid passing into the main sewer shall not exceed six times the maximum dry-weather flow as estimated by the Engineer, and that the overflow-water shall be discharged into a proper stormwater sewer or watercourse so as not to cause a nuisance.

9. In all areas where, owing to the level of any portion of the drainage district, it is necessary for the sewage from such portion to be pumped into the main sewer, such area shall be sewered strictly on the separate system, and no connection from rainwater-pipes, surface-water gullies, or subsoil-water drains shall be permitted.

10. Polluted water from a stable, dairy, or paved yard, or from the floor of a building used for manufacturing or business purposes, shall not be conveyed or discharged into a local sewer or drain connected directly or indirectly with a main sewer unless such local sewer or drain shall have in connection with such premises a silt-trap of dimensions and material to be determined by the Engineer.

11. No person shall deposit, or cause, permit, or suffer to be deposited, in any water-closet, pan, trap, or yard gully connected with a drain, or into any drain, any ashes, house refuse, or other solid matter not being ordinary household sewage.

12. No person shall discharge, or cause, permit, or suffer to be discharged, or to flow into any sewer or into any drain connected directly or indirectly with a main sewer any chemicals (whether gaseous, liquid, or solid) or anything of an explosive nature (whether gaseous, liquid, or solid).

13. No person shall discharge, or cause, permit, or suffer to be discharged or to flow into any sewer or into any drain connected directly or indirectly with a main sewer any waste liquids or refuse products of any manufacturing process, without the express sanction of the Board having been first obtained in writing, and then only for and during such period or periods and subject to the observance of such conditions (including a power of cancellation of such sanction) as the Board may think fit to impose; and in particular such waste liquids or products shall, if required by the Board, be first passed through the strainers sufficient to prevent the passage of any solid matter into the sewer.

14. No person shall discharge, or cause, permit, or suffer to be discharged or to flow directly into a sewer or into a drain connected directly or indirectly with a main sewer any hot liquids or steam, but shall retain the same in a cooling apparatus until the temperature is reduced to below 100° Fahr.

15. No person shall discharge or empty into, or cause, permit, or suffer to be discharged or emptied into, any sewer or into any drain connected with a main sewer (whether directly or in such a manner as to reach such sewer or drain) from any hospital institution or other private or public building any solid or liquid matter from patients suffering from any infectious or contagious disease, without first thoroughly disinfecting such discharge.

16. No person shall sweep, rake, or place any dust, earth, or rubbish into or in any sewer or any drain connected directly or indirectly with a main sewer, or any sanitary convenience or sanitary appliance directly or indirectly connected with a main sewer.

17. No person shall sweep or rake or place into or in an inlet chamber or appliance (including a grid) giving access to a main sewer, or permit or suffer anything to enter a main sewer by means of any such opening or appliance, save such matter as may be carried in with the water entering by a local sewer in the course of the legitimate use of such sewer.

18. No person shall destroy or injure any drain, or covered or open watercourse, or any building, erection, structure, method of ventilation, machinery, dam, tank, reservoir, or other work or thing being part of or connected with any drainage-works vested in or under the control of the Board, or in any way stop or obstruct or otherwise interfere with any drain or watercourse or other drainage-work.

19. No contributing body shall fail or neglect to give the statutory notice of its intention to connect a local sewer to a main sewer as provided by section 58 of the Auckland and Suburban Drainage Act, 1908, nor shall by itself, its officers, or its workmen make on a main sewer any connection which has not been approved by the Drainage Board.

20. Every local authority having control of local sewers or drains which are directly or indirectly connected to a main sewer shall maintain such local sewer or drains, together with all chambers, traps, appliances, or other thing pertaining thereto, in good order and repair to the satisfaction of the Engineer.

The common seal of the Auckland and Suburban Drainage Board was hereto affixed in the presence of—
