Following the leasing by the Authority to the Municipality of Bethel Park, complete sets of plans and specifications and engineering data of the proposed installation shall be delivered in sextuplet to the Municipality of Bethel Park for its approval. Such data shall in all ways conform to the present or future requirements of the Pennsylvania Department of Health and the Sanitary Water Board. They shall be prepared, signed, and sealed by a registered professional engineer legally qualified to practice in Pennsylvania, whose work and experience is satisfactory to the Department of Health and Sanitary Water Board. The Municipality of Bethel Park or Authority will present such plans to the above department for approval, and it will be necessary that the applicant pay the necessary filing fee charged by the Department of Health and which is required to accompany the application for the permit. At the present time this charge is $25 for each permit. Any corrections or revisions in the plans shall be made as required by the Department of Health, and after the permit is granted, all construction shall be strictly in accordance with such plans and specifications.
58.5.4. 
Plans and engineering data intended to be submitted to the Municipality of Bethel Park or Authority shall be prepared on sheets 24 by 36 inches in size with 1/2 inch border on the top, bottom and right-hand edge, and a 1 1/2 inch border on the left-hand edge for binding. A three-by-five title box shall be located in the lower right-hand corner. The name of the professional engineer who prepared the plans, his signature and his seal will appear near the title box. This engineer shall hereinafter be referred to as the Engineer.
58.5.5. 
The plan of the entire subdivision showing the complete sanitary sewer layout shall be accurately presented, together with a carefully prepared profile of the individual sewers showing the ground surface, the proposed street grades and the elevations of the flow line of the manholes. All elevations shall conform to the United States Government Sandy Hook datum and each subdivision shall have a permanent bench mark established in the convenient central location.
58.6.1. 
Velocity of flow. No sewers shall be laid on a grade such that the mean velocity of flow when full or half full is less than two feet per second when using Kutter's or Manning's formula with a roughness coefficient of N = .013.
58.6.2. 
Sewer capacities. In the design of the system, the capacity of the sewers, both collecting and transportation, which in the future will be installed by property owners or owners of subdivisions should conform to and adhere to the following. The minimum size collecting sewer to be used shall be eight-inch diameter, using salt-glazed vitrified clay pipe or approved equal, and the minimum grade for this size sewer shall be 0.4 foot per one-hundred-foot length. An eight-inch sewer on this minimum grade shall not have attached to it more than 240 single houses or equivalent population for apartment houses, commercial establishments, industrial or other type usage. Each apartment shall be considered the equivalent of single house. Commercial establishments shall be rated on the basis of the amount of sewage contributed equivalent to the discharge from a single-family house or 450 gallons per 24 hours. Where this condition is exceeded, larger sewers at adequate grades shall be supplied as may be required by the Authority.
58.6.3. 
Tightness. All sewers shall be constructed watertight and shall be tested before connection into the sewers, and will not be acceptable if there is a greater leakage than the equivalent of 10,000 gallons of water per day per mile of sewer, including manholes proportioned to the length of sewer installed. Manholes shall be placed on all sewers at junctions and at each change in grade or alignment, and in straight lines on sewers up to 15 inches in diameter at intervals of not more than 400 feet.
58.6.4. 
Test for watertightness. Before the sewer will be accepted and can be attached to deliver sewage to the sewerage system, it shall be tested by the Engineer of the subdivision or property owner, who shall certify that it has passed the required tests as set forth stating the amount of leakage observed during the test. Such statement shall be forwarded to the Municipality of Bethel Park or Authority in triplicate and must be attested by a notary public.
58.7.1. 
All sewers shall be laid to exact line and grade showing a full circle of light from manhole to manhole. The pipe shall be adequately bedded so as to prevent any settling or cracking. Where the depth of trench is excessive, the pipe shall be adequately cradled. All backfill shall be adequately tamped in place within the pipe zone, which shall extend not less than one foot above the crown of the pipe. Where sewers are laid in streets, the backfill shall be adequately and thoroughly compacted for the entire depth of the trench. All manholes shall have channels in the bottom extending up to the center of the outlet, and shall be so constructed as to smoothly and evenly divert the sewage into the outlet of the manhole. Manholes shall be equipped with ladder bars of durable material and so protected to have a long and adequate life. Cast-iron covers shall be used of a type and size meeting the standard requirements of the Authority. All manholes shall be watertight and shall be thoroughly plastered outside to accomplish this end.
58.8.1. 
Where construction conditions or locations of sewers are such that standard construction is not adequate, special construction shall be used which will meet the requirements of the Authority, its Engineer and the Department of Health. Should the sewers cross rights-of-way of public utilities, the construction shall be made in accordance with the requirements of the Authority owning or operating that utility.
58.8.2. 
Where the contractor lays sewers across, along or through rights-of-way, roadways, etc., belonging to the state, County, municipality or township, the regulations and stipulations set up and required for those owners shall be observed, and all work shall be in conformance with the requirements set forth by that said owner.
58.8.3. 
The contractor is warned that at certain locations where his construction is to be performed there may be existing under ground or concealed structures, mainly utility mains and services, and in some cases drainage, storm and other pipe lines, conduits, etc. Before the contractor begins excavation on any work, he shall ascertain from the public utility companies supplying the residences of the municipality as to whether they have any mains or services in the location he proposes to perform his work, and to obtain as near as possible the locations of the same so that he may protect them from damage. Failure on the part of the contractor to protect any such concealed structures during his operations shall impose the requirement upon him to restore and put back into good condition any such structures damaged. This shall be done in a manner satisfactory to the authority owning or having jurisdiction over the structure.
58.9.1. 
Clearing and grubbing shall consist of the removal of all trees, brush and other vegetation and old structures or obstructions from the site of the work, which will be required to be removed so that the planned construction may be made. All live trees shall be protected and not removed unless permitted or ordered by the Engineer. Where existing major structures are to be removed, the work to be performed is described in the detail specifications which shall be prepared by the engineer. All brush or other disposable matter shall be burned. All work under this heading shall be done sufficiently ahead of topsoil removal and excavation so as not to interfere with those operations. The contractor shall remove stumps and large roots and refill the depressions with suitable earth fill compacted as outlined under the various types of backfill. Clearing and grubbing shall be considered as a part of the work done under general excavation, unless otherwise covered in the detail specifications.
58.9.2. 
Before beginning of the general excavation, all topsoil over the areas of the site where general excavation is to be done; fill to made; or the storage of excavation is to be made, shall be stripped off to the depth determined by the Engineer, or usually about a depth of eight inches, and shall be stored until construction is completed and backfill is made. The topsoil shall then be replaced as the upper layer of backfill to a depth of not less than six inches, and leveled to an even grade so that the final grade shall be required by the plans.
58.10.1. 
Sewer lines are to be laid in trenches with cover as specified on the plans or called for or as is necessary to secure proper alignment. Bell holes must be excavated around all joints, and trenches must be of a sufficient width to permit a thorough caulking of the joints and inspection of the work. Care must be taken in excavating the bottom of the trench to secure a uniform grade so that the pipe can rest upon it throughout its entire length. The bottom of the trench should be excavated so as to conform to the curvature of the pipe and afford good bearing surface, and, to this end, machine work shall be permitted to no greater depth than 2/3 the diameter of the pipe below the crown elevation of the pipe. Contractor shall excavate all bell holes before lowering the pipe into the trench. Where rock is encountered, the excavation shall be carried below the bottom of the pipe for a distance of six inches, which shall be backfilled with earth or clay well tamped to proper grade. Surplus materials shall be disposed of as directed. No more than 400 feet of open trench shall be permitted at any time.
58.10.2. 
Where the contractor passes through areas which are cultivated or grassed, he shall remove all topsoil first before performing his trench work, depositing such topsoil carefully so that it may be used as the final backfilling of the trench for restoration of final grade. The trench shall be brought to the proper shape by trimming with suitable tools to lines stretched between the outside of the pipe and template. When excavation work is done under unit price items, pavement lines shall be as to depth, the amount required to adequately bed the pipe of a firm foundation and as to width, the diameter of the pipe, for pipes up to twenty-four-inch diameter plus 18 inches, and for pipes 24 inches and over in diameter the diameter plus twice the wall thickness of the pipe plus two feet for depths of trench up to six feet above the outside bottom of the pipe. The width of the trench shall be increased 18 inches for each six feet of extra depth above six feet to provide for sheeting and bracing. Any excavation for cradle shall be included.
58.10.3. 
Materials excavated from trenches shall be deposited or stored on the side of the trench furthest from the road metal or pavement in such manner that there will be in interference with the flow of water in any gutter, drain pipe, culvert, ditch or waterway, unless the contractor is specifically permitted to do otherwise by both the public authority having jurisdiction over the highway and the Engineer. When excavated materials are deposited on or along a public high way, the contractor shall protect the traveling public by placing watchmen, warning signals, or both, as required. During the time trenches are open, the contractor shall provide and maintain free access to all adjacent properties. All excess excavation shall be immediately removed from the right-of-way.
58.10.4. 
Where necessary, the trench shall be provided with sheeting properly braced to protect the lives of the labor employed on the work and property adjoining the trench. In any case, the contractor shall provide sheeting and bracing in all trenches six feet or more in depth, and in accordance with state and municipal regulations. The width of the trench shall be sufficient to permit ample space for the workmen to construct the sewers in an efficient manner, and additional space shall be provided where required for sheeting, bracing and equipment. Sheeting, where used, shall not be removed before first securing the permission of the Engineer. When sheeting is removed, contractor shall assume full responsibility for any damage to structures, property, etc., arising from failure to leave in place a sufficient amount of sheeting and bracing. The contractor is warned there where other underground structures such as power, telephone, gas, water, sewer or other services are located, care shall be taken to determine their locations and protect them from damage. However, should any such structures or services be damaged, they shall be repaired or replaced in a manner satisfactory to the Engineer or the owners of such structures. All necessary sheeting and shoring shall be provided to protect these structures and on all ditches six feet or over in depth, or as may be required by state or municipal regulations for the protection of workmen. Material used for the repair or replacement of any damaged structures shall be similar to that of the existing structure. All cost of repair or replacement shall be borne by the contractor, unless otherwise provided for by the detail specification.
58.11.1. 
Selected backfill material free from rock or boulders shall be deposited in the trench simultaneously on both sides of the pipe for the full width of the trench, in layers, and to an elevation of at least one foot above the top of all pipe, leaving the joints exposed for examination during the pressure test. The backfill material shall be moistened if necessary, tamped in thin (maximum four-inch) layers, and thoroughly compacted under and on each side of the pipe to provide solid backing against the external surface of the pipe.
58.11.2. 
Succeeding layers of backfill may contain coarser materials, and shall be compacted thoroughly by puddling with hose, and long pipe nozzle, or by tamping in layers of not more than four inches with mechanical tampers as may be ordered by the Engineer, if the material does not puddle readily. (Note exception where settlement is important.) Contractor shall furnish necessary water at his own expense. Topsoil shall be placed upon the upper six inches where planting, seeding or sodding is required.
58.12.1. 
No rock or boulders shall be used in the backfill for at least one foot above the top of the pipe, and no stone larger than eight inches in its greatest dimension shall be used in the backfilling.
58.13.1. 
Where it is important that the surface of the backfill be made safe for vehicular traffic as soon as possible, or where a permanent pavement is to be placed within a short time, all but the upper 12 inches of backfill shall be of approved moist material, thoroughly compacted in thin (about four-inch) layers by tamping, and shall be brought to the required surface grade. Stone, gravel, granulated slag or cinders shall be the material used for the temporary fill in the upper 12 inches. Should settlements occur in excess of 1 1/2 inches below the street grade, the contractor shall furnish and install additional material to maintain the surface at street grade.
58.14.1. 
Wherever, in the opinion of the Engineer, surface settlement is not important, tamping may be permitted in the layers above those described under 58.11, Backfill procedure at pipe zone, and the backfill shall be neatly rounded over the trench to a sufficient height to allow for settlement to grade after consolidation, and future settlements within the period of a year shall be rectified by adding material to bring the surface to a little above grade. Topsoil shall be placed to a depth of not less than six inches where planting, seeding or sodding is to be the final surface.
58.15.1. 
Any deficiency in the quantity of material for backfilling the trenches, or for filling depressions caused by settlement, shall be supplied by the contractor.
58.16.1. 
The contractor shall replace all surface material, and shall restore paving (unless otherwise stipulated), curbing, sidewalks, gutters, shrubbery, fences, sod and other surfaces disturbed to a condition equal to that before the work began, furnishing all labor and material incidental thereto. In restoring paved surfaces, new pavement is required, except that granite paving blocks, sound brick or asphalt paving blocks may be reused.
58.17.1. 
Where sewer lines are carried through cinders, shall be used for backfilling against the pipe and only clay or earth, free from cinders, may be used for backfilling around the pipe, thoroughly tamped, and to a thickness of not less than nine inches all around and above the pipe for protection from cinders.
58.18.1. 
Following the completion of the work, the contractor shall maintain the surface of the unpaved trenches, adjacent curbs, sidewalks, gutters, shrubbery, fences, sod and other surfaces disturbed, for a period of 12 months thereafter, and shall maintain the repaved areas (if paved by contractor) and adjacent curbs, gutters and sidewalks for one year. All material and labor required for the maintenance of the trenches and adjacent structures shall be supplied by the contractor, and the work shall be done in a manner satisfactory to the Engineer.
58.19.1. 
The contractor shall be responsible for such permits, including cost thereof, as may be necessary for crossing the state highways or other highways not under the control of the owner. Repaving of such highways shall be performed in accordance with the requirements set forth in the regulations of that governmental authority.
58.20.1. 
Backfill shall follow the provisions outlined above, except that all backfill up to the final grade shall be thoroughly compacted by mechanical tampers or adequately weighted rollers.
58.21.1. 
Embankment around structures shall be constructed to the lines and grades as shown upon the plans. This embankment shall be composed of material from the excavation, and shall be put down in layers not exceeding four inches in thickness, and shall be thoroughly rolled with a suitable roller or other means taken to compact it and bind it in thoroughly with the layer below. Embankments shall be finished off with the topsoil excavated from the site. Topsoil shall have a thickness on the berms, embankment and slopes of not less than six inches.
58.22.1. 
Surfaces to be seeded shall be carefully leveled or graded, prepared and raked, and then seeded with a mixture of seed consisting of 20% Kentucky bluegrass, 15% red top, 10% English rye grass, 15% chewing fescue, 30% seaside bent, and 10% white clover (for lawns around buildings, the clover shall be replaced with that amount of Kentucky bluegrass). The surface shall then be covered with 3/4 inch of peat moss evenly spread. All sloped surfaces shall then be covered with muslin or cheesecloth in a continuous surface properly anchored in place. The contractor shall keep surface adequately watered until grass has obtained a uniform length of two inches. Maintenance of lawns shall be given by the contractor until the acceptance of the construction by the owner.
58.22.2. 
Sod shall be furnished and planted over those areas requiring sodding. Before lifting, the grass should be cut to a length of approximately 1 1/2 inches, and the sod then cut in squares and lifted out, taking care to include the major portion of the roots and topsoil, but not less than two inches. The surface on which the sod is to be planted shall be covered with topsoil to a depth of not less than three inches, raked level, and not less than 200 pounds of commercial fertilizer per acre shall be raked in. The surface shall then be wetted and the sod laid, care being taken to butt the joints closely and the surface tamped to expel the air between the sod and topsoil. Any voids shall be filled with topsoil and seeded. The sod shall be kept watered until a union has been made between sod and earth. The lawn shall be cared for until acceptance by the owner, and any sod that becomes burned out or dies shall be replaced.
58.23.1. 
Standard strength vitrified clay sewer pipe and fittings shall conform to the ASTM Specifications, Serial Designation C 13-50T and any subsequent revisions, generally known to the trade as double-strength vitrified terra-cotta sewer pipe. Special attention is called to that portion of the specifications dealing with inspection and rejection. Pipe fittings shall be of a standard manufacture and shall be first grade, salt glazed, vitrified clay sewer pipe with shell vitrified throughout and perfectly burned without cracks, blisters, pimples or other imperfections. The socket and spigot ends must be cut off at right angles with the axis of the pipe. All pipe shall be well and smoothly glazed over both inner and outer surfaces, except the insides of the sockets and the outsides of the spigots for a distance equal to the depth of the socket. The interior of the socket and the outside of the spigot shall be scored with not less than three scorings. The length of pipe shall not be less than two feet for sizes six inches and under, and three for sizes eight inches and larger.
58.24.1. 
In locations where heavy loads occur on clay sewer pipe, the pipe shall be extra-strength clay sewer pipe, generally known to the trade as triple-strength vitrified terra-cotta sewer pipe, and shall conform to the ASTM Specifications, Serial Designation C 200-53T and any subsequent revisions. In all other respects, the pipe shall conform to that outlined in the preceding paragraph.
58.25.1. 
Before sewer pipe is placed in position in the trench the bottom and sides of the trench shall be carefully prepared and, if necessary, bracing and sheeting installed as provided under 58.10, Excavation for sewers. A mason's line shall then be tightly stretched across the tops of grade boards accurately set above ground level, parallel to, and directly above, the axis of the pipe to be installed, this line to be supported at intervals not exceeding 50 feet. The exact line and grade for each section of pipe shall be determined by plumbing and measuring down from this line to the invert of the pipe being placed. Each pipe shall be accurately placed to the exact line and grade called for on the plans.
58.25.2. 
Each piece of pipe and special fitting shall be carefully inspected before it is placed, and no defective pipe shall be laid in the trench. Pipe laying shall proceed up-grade starting at the lower end of the grade and with the bells uphill. All pipe shall be laid in the presence of an inspector representing the owner or engineer. Trench bottoms found to be unsuitable for foundations after pipe laying operations have started shall be corrected and brought to exact line and grade with compacted earth where necessary. When so directed by the Engineer, gravel, crushed stone, slag or concrete cradle shall be installed where necessary to provide a satisfactory bearing surface.
58.25.3. 
Bell-holes shall be of sufficient size to allow ample room for properly making the pipe joints. Bell holes shall be cut out not more than 10 joints ahead of pipe laying. The bottom of the trench between bell holes shall be carefully graded so that the pipe barrel will rest on a solid foundation for its entire length. Each joint shall be laid so that it will form a close concentric joint with adjoining pipe, and so as to avoid sudden offsets or inequalities in the flow line. If pipes are out of round but within the tolerances allowed by the ASTM Specifications, they shall be rotated to provide smooth and even inverts one with another.
58.25.4. 
When so authorized by the Engineer, and when asphaltic jointing compound is used, alternate joints may be poured before the 2 sections are lowered into the trench. In such cases, the joint must be allowed to set and the bottom of the trench carefully graded, so that the joints so made will not be placed in strain or broken by unequal bearing after the pipes are placed in position in the trench.
58.25.5. 
Joints shall be prepared in the manner hereinafter specified. As the work progresses, the interior of all pipe in place shall be thoroughly cleaned. On small pipe a swab or drag shall be kept in the pipe line and pulled forward past each joint immediately after it has been made. After each line of pipe has been laid, it shall be carefully inspected, and all earth, trash, rags and other foreign matter removed from the interior.
58.25.6. 
After the joints have been completed, they shall be inspected, tested and accepted by the Engineer before they are covered. The pipes shall meet test requirements for watertightness and any leaks or defects discovered at any time after completion of the work shall be immediately repaired. Any pipe which has been disturbed after the joint was made shall be taken up, the joint cleaned and remade and the pipe relaid at the contractor's expense. All pipe in place shall be carefully protected from damage until the backfilling operations have been completed.
58.25.7. 
Water shall not be allowed to run or stand in the trench while pipe laying is in progress or before the joints are completely set or before the trench has been backfilled. The contractor shall not open up at any time more trench than his available pumping facilities are able to dewater.
58.25.8. 
Backfilling of trenches may be started immediately after the pipe in place has been inspected, tested and approved by the Engineer. Backfilling shall be performed in the manner hereinbefore specified under backfilling.
58.26.1. 
Where ground conditions require, or where by order of the Engineer, the plans or the detail specifications, cradle shall be installed under sewer pipe. One of three types shall be furnished as follows:
1. 
Clay cradle or sand cradle. Where sewer pipes are in trenches with a cover over the crown of less than six feet and will not be subjected to heavy traffic strains, no cradle will be required, and, where rock or unsuitable foundation is encountered, a cradle of mechanically tamped clay or sand placed in three-inch layers to a depth from six inches below the bottom of the pipe up to or beyond the lower point of the pipe shall be installed. A bed shall then be cut out as described under 49.25, Laying sewer pipe.
2. 
Gravel or crushed stone cradle. When sewer pipes are laid in trenches with a cover of more than six feet or where subjected to medium traffic loads or rock is encountered, a gravel or crushed stone cradle shall be installed, when called for on the plans or in the detail specifications. The gravel, crushed stone or crushed slag shall meet the specifications for concrete aggregate, small for pipes up to twelve-inch diameters, medium for pipes twelve-inch to twenty-four-inch diameter, and larger for pipes over twenty-four-inch diameter. Cradle shall be carried to 1/3 the height of the pipe for trenches less than 12 feet deep, and to three inches above center line for trenches over 12 feet deep. The cradle material shall be adequately and compactly tamped in place, using mechanical tampers if necessary, taking care not to heave, misalign, crack or otherwise injure the pipe and joints.
3. 
Concrete cradle. Where sewer pipes are laid under conditions exceeding those outline in Paragraph 2 preceding, or required by the plans, detail specifications or by order of the Engineer, one to two to four (1:2:4) concrete shall be substituted for the gravel.
58.27.1. 
The following types of joints, as well as other types which may be approved in writing by the Engineer shall be accept able on vitrified clay sewer pipe. The joint used, however, regardless of type, shall be the kind especially suited for use with the type of pipe involved and in the location used, and as will guarantee leakage below the amounts hereinafter set forth under58.28, Testing sewers.
58.27.2. 
Before any joints are made on the ground, the contractor shall demonstrate to the Engineer, by pouring at least one sample joint, that the methods which he employees conform to the following specifications and will provide a watertight joint, and further that the workmen who are intended for use on this phase of work are thoroughly familiar and experienced with the type of joint proposed.
58.27.3. 
Cement grout joints.
1. 
Under the bell of the pipe last laid, a suitable form of unbleached muslin shall be placed of such a length as to at least encase the lower 2/3 of the pipe. The spigot end of the pipe shall be inserted into the bell to its full depth, and a gasket of jute or oakum, twisted and thick enough to even up the inverts shall be caulked into the joint for the full circumference of the pipe and to within 1 1/2 inches of the face of the bell for 18 inches and smaller pipe, and 2 1/4 inches for larger pipe. The ends of the muslin shall be brought up around the pipe and secured with ties on each piece of pipe. The annular space then shall be filled with cement grout just thin enough to be forced through a hose, and around and tightly into the joint using a grout pump. The muslin form shall remain in place, and before the grout has set, the upper portion of the joint is then to be formed of cement mortar, well caulked into place.
2. 
The cement grout and cement mortar used shall have the composition by weight as follows:
a. 
Three parts clean sharp sand;
b. 
Two parts portland cement;
c. 
One part Master Builders Company Embeco or equal*.
To this shall be added just enough water to make a workable mix.
(*Product of equal manufacturer may be used according to that manufacturer's specifications and the Engineer's approval.)
3. 
Weston's gasket and form will be acceptable as an alternate to the above specified method, using joints made in accordance with the manufacturer's specifications with cement grout and mortar as above specified.
58.27.4. 
Cement mortar joints. A gasket of jute or oakum shall be rolled sufficiently thick to bring the invert of the spigot end of the pipe being laid smooth and even with the invert of the bell end of the pipe previously laid. This gasket shall be dipped and thoroughly soaked in a cement grout com posed of neat portland cement and water. The gasket shall then be laid in the bell for the lower third of the circumference of the joint and covered with mortar from base to bell to end of bell. The spigot of the pipe shall then be inserted and carefully driven home, after which a small amount of mortar shall be inserted in the annular space around the entire circumference of the pipe. The ends of the gasket shall then be wrapped around the pipe and solidly rammed into the joint with a caulking tool, providing clearance from end of bell to gasket, as above specified for cement grout joints. The mortar previously placed shall be driven ahead of the gasket. The joint shall then be filled with portland cement mortar as outlined in the preceding paragraph. This mortar must be placed by hand, and care must be taken to completely fill the joint entirely around the pipe by pushing the mortar in by hand, using a rubber glove with fingers, and a wooden caulking tool. The joint shall be beveled off at an angle of 45° with the outside of the pipe and shall be protected by a strip of muslin placed completely around the joint and tied in place.
58.27.5. 
Hot poured asphaltic compound joints.
1. 
If hot poured asphaltic compound pipe joints are used, the inside of the bells and the outside of the spigot ends of all bell and spigot sewer pipe and fittings shall be painted with a primer recommended and/or sup plied by the manufacturer of the jointing material used. This painting shall be done at least four hours before the pipe is laid, or as recommended by the manufacturer. The pipe and fittings shall be clean and dry before painting. Pipe joints shall be made with a compound having a bituminous base, such as Joint Seal No. 313, as manufactured by the H.H. Robertson Company, Pittsburgh, Pennsylvania, G-K compound or Atlas JC-60 compound as manufactured by the Atlas Mineral Products Company, Mertztown, Pennsylvania, or approved equal. This compound shall be heated in a suitable heater to a temperature specified by the manufacturer so that it can be poured rapidly and smoothly. Before pouring, the joints shall be clean and dry, and a gasket of dry unoiled hemp or jute shall be caulked into the annular space. After the gasket is properly caulked, a suitable asbestos runner shall be placed around the joint and mudded, and the compound shall be poured in such a manner that it will run around the pipe and completely fill the annular space. When permitted by the Engineer, two pipes may be joined on the bank, care being taken to preserve the proper alignment of the pipe both on the bank and while being lowered into the trench. Whether jointed on the bank or in the trench, primer and joint compound shall be used on every joint.
2. 
If die-cast sewer pipe joints are used, they shall be similar and equal to the Slipseal Sewer Joint as made with dies and materials furnished by the Universal Sewer Pipe Corporation, Cleveland, Ohio, Die Cast Sewer Joint as made by American Vitrified Products Company, Cleveland, Ohio, Atlas Slipjoint Compound as made by the Atlas Mineral Products Company, Mertztown, Pennsylvania, or approved equal. Sewer pipe shall be primed and cast with Slipseal or equal approved die-cast tapered-type joint, which shall be made by fitting the spigot and socket of the pipe with collars of Slipseal bituminous compound. Compound shall have a melting point of 240° - 270° F., and a penetration of 4-7 at 77° F. A lining or ring of this jointing material shall be die-cast into the socket of the pipe. The spigot shall be fitted with a collar of the same material, die-cast around the end of the pipe, and of a size such that when shoved firmly into the socket portion of the pipe, a tight fit between the socket and the spigot end of the pipe will be made. All pipe must be dry and clean when lining and collar cast, and a compound must be poured at a heat high enough to procure proper adhesion to the pipe. When laying these pipes, the lining and collar shall be painted with Slipseal solvent, which shall cause their surfaces to become plastic or tacky, and when the pipes are shoved firmly together, the joint material shall unite, and incidental to the diffusion of the solvent, congeal and become one homogeneous body. The foregoing is a brief description of the method of making this type of joint, however, during construction the manufacturer's directions shall be followed in all respects.
58.27.6. 
Asphaltic compound cold troweled joints. If asphaltic compound cold-troweled joints are used, they shall be made with a cold, mastic, asphaltic compound such as DeWitt's No. 10, as manufactured by DeWitt Products Corporation, Detroit, Michigan, Kalkite, as manufactured by the Presstite Engineering Company, St. Louis, Missouri, or approved equal.

The rubber used in the gaskets shall be natural or synthetic type and so compounded to give a long, enduring life and service and shall be such as not to disintegrate in the presence of air, liquids or gases to which it may be subjected in the service in which it is to be placed.
2. 
Rubber joints of the rubber tube type filled with grout under pressure after installation in the bell of the pipe, as developed by the Caly Sewer Pipe Association, Inc., Columbus, Ohio, shall be permitted on vitrified clay sewer pipe installations. The joints shall be installed in strict accordance with the directions and requirements of the manufacturer. If this type of joint is used, two lengths of pipe may be jointed outside the trench with hot poured asphaltic compound as previous specified, resulting in a sewer line constructed with alternate joints of the hot poured asphaltic compound type and alternate joints of the rubber tube type.
58.27.8. 
Plastic joints. Premoulded joints of the plastic type shall be similar to those manufactured by the American Vitrified Products Company, or equal. The joints shall be premoulded in the bell and on the spigot with a satisfactory type of plastic material using machined dies of the proper size and arrangement to produce a tight joint when the pipes are forced together in the trench. The plastic material employed for the joints shall be compounded to give a long life in the service in which it is to be used. The directions of the manufacturer shall be strictly followed in the making of the joints and assembling in the trench.
58.27.9.

d. 
Pipe must not be moved in the slightest after the joint is made.
58.28.1. 
The Commonwealth of Pennsylvania requires that the leakage of sewers shall not exceed the following test requirements which includes all appurtenant construction. The contractor shall certify in quadruplicate previous to the payment of the final estimate that he has tested all sewers and they have less leakage than set forth below, so that the Engineer may transmit the same to the proper authorities if requested. Sewers and drains shall not exceed an infiltration of 10,000 gallons of groundwater per mile of sewer per 24 hours, regardless of pipe joint type that may be used. Conformance with this requirement shall be verified by performance of exfiltration tests to be made, certified to, and paid for by the contractor and conducted as follows:
58.28.2. 
After replacement of broken or cracked pipe, repair of defective joints and vitrification of the sewer installation to true line and grade that also shows a full circle of light from manhole to manhole, and after cleaning and conditioning the sewer free from deposits, joint drippings or extrusions, or from foreign matter of any kind, each section of sewer between manholes, or for longer distances of allowed, before backfilling, shall be maintained completely full of water for a period of not less than 30 minutes to allow for absorption of water by the sewer. By use of preinstalled riser sections of pipes at manholes if necessary, or by plumber's plugs and riser, a column of water shall then be maintained at least four feet above the uppermost top section of sewer under test for sewers with grades of 1% or less, and to one inch above the crown of the upper end of the sewer for grades between 1% and 5%, and as the Engineer directs for greater grades; and the rate of leakage, for a period of not less than 30 minutes thereafter, accordingly determined, must not exceed that proportion for the length of sewer under test to 10,000 gallons per mile of sewer per 24 hours.
58.28.3. 
In case the water table in the trench, at time of test, is above the highest invert of the sewer section under test, the column of water above specified shall be accordingly increased.

After backfilling has been completed, the excavated area, if located in a street, alley or sidewalk, shall be provided with a temporary surface in the manner stipulated under 58.13, Procedure where settlement is important.
58.35.1. 
Where sewers are to be constructed beneath paved highways, railroad rights-of-way or at other locations, the contractor may use one of the following methods outlined below, providing it meets the regulations established and required by said owner, and the work is done in conformance with the requirements of said Authority and the Engineer.
1. 
The contractor may use the tunneling method, using sheeting properly braced, or tunnel liners which he may remove or leave in place as required. The space, however, between the permanent sewer or water pipe and the tunnel walls shall be completely filled, using crushed stone of a size meeting the requirements for medium grading of concrete aggregates.
2. 
The contractor may shove or jack reinforced concrete pipe under the rights-of-way. The pipe used shall be extra strength, tongued and grooved, reinforced concrete pipe, equal to that known as railroad culvert pipe, type 2.
3. 
The contractor may employ the boring method as developed by the Young Engine Company, Canton, Ohio, or equal, using a mechanical boring machine. For this method, the contractor shall use genuine wrought-iron plate, Armco iron or copper-bearing-steel casing or pipe, having wall thickness of not less than 3/8 inch for twelve-inch diameter, or larger, and 5/16 inch for less than twelve-inch diameter. The permanent line shall be installed inside this iron casing.
4. 
Where metal pipe is specified for the permanent line, without the use of a casing, it shall be genuine wrought-iron Armco iron or copper-bearing-steel casing or pipe, having a wall thickness of not less than 3/8 inch for twelve-inch diameter, or larger, and 5/16 inch for less than 12 inches in diameter. This type of line may be installed using the Young Engine Company, or equal, boring machine; or the line may be shoved or jacked in place and the excavated material removed by hand or other approved means.
58.35.2. 
All lines installed by any of the above methods shall be maintained on line and grade.
58.35.3. 
The method of installation and kind of material proposed shall receive the approval of the Engineer.
58.36.1. 
Where it is necessary to remove paving in order to install sanitary sewers, services or service connections, the paving shall be cut squarely and evenly one foot on each side wider than the trench width. The trench shall be excavated, and after installation of the sewer line the backfill shall be thoroughly compacted into place. The paving shall then be restored, of the type similar to that existing, and in a manner required by the authority having jurisdiction over the road or street. Where concrete paving is cut, reinforcing steel or mesh shall be installed to adequately tie the replaced paving together. Where macadam is cut, the underlying layers of paving, either telford, slag or other type base, shall be adequately restored and compacted into place and then finished with surface coat of tarbound macadam similar to or better than the existing road surface. All work shall be in accordance with the requirements of the authorities having jurisdiction.
58.37.1. 
Service connections shall be provided at all users' properties when the sewers are installed, and shall consist of a wye branch having runs of same size or diameter as the main sewer, with a six-inch or eight-inch branch connection as may be required for the property served. This wye branch shall be installed such that the branch is above the horizontal, so that the service sewer will have slope into the main sewer. In type, wye branch shall be a bend of the proper degree radius installed to bring the service sewer at a normal to the main sewer, and from this bend the service sewer, mainly six-inch diameter, but not less, shall be laid to the curbline or approximately 15 feet from the center line of the roadway or to the base of the right-of-way in which the main sewer may be installed. From this point the sewer shall be installed by the property owner using registered pipe layers or plumbers. All joints shall be temporarily plugged by having a terra-cotta plug cemented in, using asphalt or cement joint compound in such a manner as to make a tight closure but to permit removal without breaking the bell of the pipe for the extension of the service sewer. In certain cases where risers are necessary, the wye branch and bends may be tipped up to a maximum of 45° with the horizontal to avoid long, deep excavations. The service sewers, in no case shall have less than four feet of cover under the traveled surface of the roadway.
