FIRST SCHEDULE.

SPECIFICATION FOR PIPE-LAYING.

All pipes shall be double-glazed stoneware, truly cylindrical, and of uniform bore and thickness. The diameter of a pipe shall mean its internal diameter, and shall not be less than the size specified. They shall be thoroughly sound, well-burnt and glazed, perfectly straight, and free from blisters, scabs, cracks, and other imperfections.

Concrete.—Concrete shall be composed of not less than one part of hydraulic lime to three parts of gravel and two parts of sand, or five parts of fine scoria ash. These materials must be thoroughly mixed whilst dry, and then be turned over three times whilst being wetted from the rose of a watering-can.

Sand.—Sand shall be sharp, coarse, and entirely free from all impurities and dirt, and shall be washed if necessary.

Gravel.—Gravel for concrete shall be perfectly clean, and free from soil, clay, dust, or other impurities, must be screened, and shall be washed if necessary. None shall be used that cannot be passed in any direction through a one-and-a-half-inch ring.

Cement.—Cement of approved brands and quality only shall be used.

Mortar.—Mortar shall consist of one part of Portland cement to two of sand. It shall be thoroughly mixed with as much clean water as is necessary to form a thick paste, and none but freshly made mortar shall be used.

Laying and Jointing.—Trenches for pipes shall be cut straight and true, and shall be evenly graded before the pipes are laid; they shall be of such widths as to allow of the pipes being properly conjoined, and have three inches of concrete all round to permit of a thorough inspection. The pipes shall be laid straight and true to line and grade. The spigots shall in every case be fitted close home in the socket, and the space between the spigot and the faucet shall be concentric and well filled with cement mortar. After each pipe is joined the interior shall be thoroughly well cleaned out before another length is laid. Tapered pipes shall in all cases be used where different-sized pipes are connected.

Stoppers.—All provisional junctions and access openings to siphons shall have plugs set in and covered by approved puddle clay, and shall be left airtight.

Roots.—Where roots exist their ingress into the pipes must be prevented by surrounding the joint with three inches of concrete.

Wet Ground.—In wet or soft ground a layer of concrete, broken metal, or gravel must be spread under the pipe of sufficient thickness to ensure a good and sound foundation.

Filling over Pipes.—The filling round pipes shall be carefully packed and consolidated. The filling over pipes shall be inserted in layers not exceeding twelve inches in thickness, and each layer shall be carefully rammed. Where trenches are made in streets the surface of roadways and footpaths shall be left in a condition satisfactory to the Inspector.
