A. 
Hot asphaltic compound for joints of vitrified tile pipe. Asphaltic compound shall consist of bituminous material mixed with mineral matter. It shall melt and flow freely at 250° F. and shall show no loss in weight when brought to a temperature of 400° F. It shall adhere to glazed surfaces of pipe sufficiently to withstand 10 pounds of internal pressure under conditions obtained in practice. When set, it shall have sufficient elasticity to permit slight lateral flexure without injury to the joint or breaking the adhesion to the pipe. The amount of bituminous material extracted by carbon bisulphide shall be not less than 40%, and the weight of mineral matter determined as ash shall not exceed 50%. It shall show no deterioration of any kind when immersed for a period of five days in a 1% solution of hydrochloric acid or a 5% solution of caustic potash.

(2) 
House connections shall be transite.
H. 
Concrete. Concrete shall be one-to-two-to-four mix or mixed with not over seven gallons of water to a bag of cement or proportioned so as to result in a strength of 2000 pounds per square inch.
I. 
Mortar for masonry shall be part cement and two parts sand, with 10% by volume of hydrated lime added.
J. 
Brick and cement block.
(1) 
Bricks shall be hard burned, sound and without salmon or soft bricks.
(2) 
Cement blocks shall be twelve-inch blocks, with a one-thousand-five-hundred-pounds-per-square-inch load-bearing value.
(3) 
Multiplex manhole concrete blocks may be used.
K. 
Fill and backfill or gravel fill. Fill and backfill may consist of any clean rock, gravel, brickbats or soil. Two feet of clean fill over pipe shall be balanced to be equal portions of soil and rock. Plaster, cement, wood or any other rubbish may not be used.
A. 
Fill and backfill, stone, gravel or soil.
(1) 
No backfill shall be placed until sewers have been inspected and approved.
(2) 
Before placing fill, remove all caved-in or loose earth over drains. Care shall be used in backfilling not to displace tiles. Materials shall be carefully packed so as to form a dense fill without large voids or pockets.
B. 
Drainage lines and sewer lines in general.
(1) 
Trenches shall have the bottoms cut to proper pitch of lines so as to avoid filling to form uniform grade.
(2) 
Drainage lines shall be laid to a uniform pitch of not less than 0.5%. An engineer's level shall be used in establishing and checking grades and pitch.
(3) 
All pipes shall be laid with ends abutting and true to line and grade. Pipes shall be fitted together and matched so that, when laid, the invert will be uniform.
(4) 
Ends of lines, during construction, shall be kept stopped up to prevent earth entering, and all dirt must be removed from pipes as work progresses.
(5) 
No cracked or broken sections will be permitted in place.
(6) 
Cast-iron saddle-type spur fittings set in bituminous mastic shall be used for all house spurs and shall enter the sewer main in the upper quadrant. Tiles broken during this installation shall be removed and replaced.
C. 
Joints for sewer pipes of vitrified tile.
(1) 
Hot asphaltic compound joint. Hot joints shall be made with hemp or oakum gasket and hot asphaltic compound. The hemp or oakum gasket shall be closely twisted into one piece, sufficient in length to encircle the pipe completely, with lap at the top, and of proper thickness to support the spigot of the pipe at the proper flow line with truly concentric joint. The spigot shall then be inserted and driven to full depth, and hemp of oakum shall be caulked solidly into the annular space with a caulking iron. A suitable runner shall be placed and the hot asphaltic compound shall be poured to fill the annular space completely. Joints shall be free of water or foreign matter.
D. 
Sewer manholes.
(1) 
Casting shall be Campbell Foundry No. 1007 or equal and letter-marked with a minimum two-inch letter S cast into its center. Each cover shall be provided with eight three-fourths-inch diameter holes for ventilation.
(2) 
Casting shall be set on brick construction at the top of the manhole, with brick being corbelled to within one foot of the top which shall then be carried in a true cylinder to top. Wherever corbelling is required, only brick may be used.
(3) 
The balance of the manhole may be either of twelve-inch concrete block or eight-inch brick. Any portion of the manhole below 12 feet from grade shall be 12 inches thick. If multiplex manhole concrete block is used, the first eight feet may be six inches thick; from a depth of eight to 12 feet, block may be eight inches thick; below a depth of 12 feet, block may be 12 inches thick.
(4) 
The bottom shall be of twelve-inch-thick concrete and shall be below invert and shall extend beyond the outside diameter of the masonry. Inverts shall be of neatly split eight-inch tile laid in concrete above the slab. Where curves in inverts are required, they may be of formed concrete. In all cases, fill concrete and earth on top of foundation slab invert to level shall pitch to invert at 1/2 inch per foot.
(5) 
Manhole steps shall be Campbell Foundry Company Pattern No. 2581 or equal and spaced 16 inches apart and placed above the North bench.

A reversed Y-branch with the branch looking down.
[3] 
A short piece of plain-end pipe, any section of pipe as may be necessary.
[4] 
A one-eighth bend terminating at the invert of the invert of the manhole.
(b) 
The run (bell end) of this aforementioned reversed Y-branch will be extended with pipe to within the manhole and there terminate. When dropped manholes of greater drop depth than three feet are used, there shall be a one-eighth bend used after two, and one-fourth bend sweep used instead of four. In all cases, all piping herein described shall be encased in poured concrete six inches outside of pipe and fittings, and the mass supported with an adequate footing.

E. 
Tests.
(1) 
All drainage and sewer lines shall be tested if required by Village Manager or his duly designated representative and approved before filling or backfilling and shall be made watertight. The Village Manager or his duly designated representative shall be notified of dates of tests well in advance and shall witness all tests. Tests shall be 10 feet of water to be held for 12 hours.
(2) 
After filling or backfilling, all drainage and sewer lines shall again be tested as required.
(3) 
Manholes, cleanout pits, etc., shall be tested as required.
(4) 
The Village Manager or his duly designated representative shall be advised in sufficient time before backfilling to check levels.
(5)
