All valves in the lines bein(.J sterilized shall be opened and closed several times during the contact period. a.07 Standard for Polyethylene Encasement for G ray and Ductile cast Iron Pipe . .""~,_~~__~___._"..,.____..'e-'<.. 1. Scope This st.andard covers materials and installation proce- dures for polyethylene encasement to be applied to underground installations of gray and ductile cast iron pipe. 'rhis standard may also be used for poly- ethylene encasement of fittings, valves and other appurt.enancest.o gray and ductile cast iron pipe systems. 2. Definitions 2.1 PolyethLl~ne encasement. Polyethylene material, in tube or sheet for, which is used to encase gray and ductile cast iron pipe. 2.2 Sec'-!.rin9:. OVerl~ Anyone of various met.hods of holding polyethylene encasement in place at the point of overlap until backfilling operations are completed. This may be ac- complished with adhesive tape, plastic string or other suitable material. 3. Materials 3.1 Polyethylene. Polyethylene encasement materials shall be manufactured of virgin polyet.hylene possessing the characteristics shown in Table 1. 3.2 ThicJsne_es. Polyethylene material shall have a minimum nominal thickness of .008" (8 mils). The Minus Tolerance on thickness shall not exceed 10% of the nominal thickness. 3.3 .~b?_ .Sj~.?.~. 'I'he tube size -for each pipe diameter shall be as listed in Table 2. 4. Installat.ion 4.1 ~~~_!1~r~.;L. Polyethylene encasement shall be in- stalled on pipe and fittings at locations specified on the construct.ion drawings. Al- though not intended to be a completely air- and \.;ater-t;ight enclosure, the polyethylene shall prevent contact between the pipe and the surrounding backfill. 4.2 pip~. This standard includes three different methods for the installation of polyethylene encasement. Methods A and B are for use with polyethylene tubes and Method C is for use with polyethylene sheets. (See Appendix A) 4.2.1 Hethod A. Cut polyethylene t-ube to a length approximately two feet longer t.han the length of the pipe section. Slip the tube around the pipe, centering it to provide n one foot overlap on each adjacent pipe section, and bunching it accordion fashion length wise until it clears the pipe ends. Lower the pipe into the trench and make up the pipe joint with the preceding section of pipe. A shallow bell hole must be made at joints to facilitate installation of the polyethylene tube. After assembling the pipe joint, make the overlap of the polyethylene tube. Pull the bunched fX")lyethylen.e from the preceding length of pipe, slip it over the end of the new length of pipe 21lld ~3ecure in place. 'Then slip the end of the lXJlyethylene from the new pipe section over the end of the first wrap until it overlaps the joint at the end of the preceding length of pipe. Secure the overlap in place. Take up the slack width to make a snug, but not tight, fit along the barrel of the pipe, securing the fold at quarter points. Repair any rips, punctures, or other damage to the polyethylene wi th adhe- sive tape or with a short length of poly- ethylene tube cut open, wrapped around the pipe, and secured in place. Proceed with installation of the next section of pipe in the ,::;ame manner. 4.2.2. Method B. Cut polyethylene tube to a length approximately one foot shorter than the length of the pipe sect.ion. Slip the tube around the pipe, center- ing it to provide six inches of bare pipe at each end. Make polyethylene snug, but not tight; secure ends as described in 4.2.1 Before making up a joint, slip a three- foot longth of polyethylene tube over the end of the preceding pipe section, bunching It accordion fashion lengthwise. After cornplet.ing the joint, pull the three-foot length of polyethylene over the joint, overlapping the polyethylene previously installed on each adjacent section of pipe by at least one foot~ make snug and secure each end as described in 4.2.1 Repair. any rips, punctures, or other damage to the polyethylene as described in 4.2.1. Proceed with installation of the next section of pipe in the same manner. 4.2.3. .Metho~-L~ Flat sheet polyethylene shall have a minimum width twice the flat tube width shown in Table 2. Cut polyethylene sheet to a length ap- proximately two feet longer than the length of pipe section. Center the cut length to provide a one-foot over- lap on each adjacent pipe section, bunch- ing it until it clears the pipe ends. Wrap the polyethylene around the pipe so that it overlap~ circumferentially over the top qlladrant of the pipe. Place a six-inch pength of adhesive tape at approximately three-foot intervals along the pipe length, securing the cut edge of polyethylene sheet. Lower the vJrapped pipe into the trench and make up the pipe joint wj..th the preceding :eJection of pipe. A shallow bell hole must be made at joints to facili tate int,tallation of the poly- ethylene. After completing the joint, make the overlap as described in 4.2.1. Repair any rips, punctures, or other damage to the polyet.hylene as described in 4.2.1. Proceed with installation of the next~3ection of pipe in the same manner. 4.3 Pipe-Shaped Appu~~enances. Bends, reducers, offsets and other pipe-shaped appurtenances ahall be covered with polyethylene in the same manner as the pipe. 4.4 Odd-shaped Appurte~an~es. Valves, tees, crosses and other odd-shaped pieces which cannot pract- ically be wrapped in a tube, shall be wrapped wi th a flat sheet or split length of' polyethy- lene tube. The sheet shall be passed under the appurtenance and brought up around the body. Se~ns shall be made by bringing the edges to- gether, folding over twice, and taping down. Slack WJ.dth and overlaps at joints shall be handled as descriLed in 4.2.1. Tape polye- tylene securely in place at valve stem and other penetrations. 4.5 Openj.J1.9s len Ert~_a.E~!!l('o_DL. Openings for branches, service taps, blow-off's, air valves, and similar appurtenances shall be made by making an X- shaped cut in the polyetheylene and temporarily folding the film back. After the appurtenance 4.6. 4.7. is installed, tape the ;lck securely to the appurtenance and repair the cut, as well as any other damaged areas in the polyethylene with tape. Junctio~s Between Wrapped and Unwr~~9_Rj~ Where polyethylene wrapped pipe joins a pipe which is not wrapped, extend the polyethylene tube to cover the unwrapped pipe a distance of at least two feet. Secure the end with cir- cumferential turns of tape. Backfill for Polyethylene Wrapped~_~. Backfill material shall be the same as specified for pipe without polyethylene wrapping. Special care shall be taken to prevent damage to the polye- thylene wrapping when placing backfill. Back- fill material shall he free from cinders, refuse, boulders, rocks, stones or other material that could damage polyethylene. In general, backfill- ing practice should be in accordance with AWWA Standare C-600-64, or latest revision thereof. :rab1e I Raw Material Used to Manufactu re Polyethylene Enca~ement Material Type, Class, Grade, other Characteristics.....

There shall be pLlced <:lround the base of the hydrant not less than seven (7) cubic feet of sound broken stone or clean gravel, or other suitable material, t.o pro- vide reservoir capacity so that the hydrant will completely drain when closed. c. Fire hydrants shall be placed on block corners or near the center of the block in such a manner as to put all of every lot within a radius of 500 feet (preferably 400 feet) of a fire hydrant. (This 500 feet is the hose laying along streets from fire hydrant by Fire Departmen t . ) d. All fire hydrants shall have a valve opening of not less than 5 inches and shall be placed on mains of not less than 6 inches in diameter. Six-inch valves shall be placed on all fire hydrant leads. 4. Railroad and Highvlay Cros[;i ngs 4.01 Materials - The carrier pipe shall be cast--iron, ductile-iron, or polyvinyl chloride and shall conform to the re- quirements of the applicable sections included in these Technical Specifications. The encasement pipe shall be corrugat~ed galvanized metal pipe of t'he dj <Jmeter and gauge shown on the plans. Corrugated metal pipe shall meet the re- quirements of Federal Specifications QQ-C-806 for "Culverts, Iron or Steel," and Amendment 2 there- of, Type I, or AASHO Standard Specifications, Designation ./1-136-42, for "Corrugated Metal Culvert Pipe." Any other materials t~hat_ may be allowed for const_ruct- ing the carrier pipe and the encasement pipe or any modifications to the materials to be furnished in this section shall be approved by the City. '.02: Constuction fv1ethods - The encasement pipe shall be installed by boring and jacking, or by open cut method as indicated on the plans. Regardless of the method used, the encasement pipe shall be in- stalled with even bearing throughout i t_s length, and all voids between the encasement: pipe and earth or rock shall be filled with stabilized pea gravel or grout. The minimum length of encasement pipe shall be determined as indicated on the reviewal of plan by the City. The encasement pipe shall be t.ightly jointed to prevent leakage. The ends of the encasement pipe shall be plugged wi t_h a clay core to prevent entrance of excessive ground water. \'lhere it is specified that~ the cast-iron carrier pipe for sanitary sewers or water mains under streets and highways is to be inst_alled by boring or jacking, all voids between the outslde of the casto-iron car- rier pipe and the bored hole shall "be filled with sand or gravel. No trench ::1hall be carried closer than ten (10) feet of all pavement edges. No dirt from trench excavation shall be piled on roadway shoulders. All trench backfill shall be mechanically tamped to the Silil1e density as surrounding ground. Before completion of this proposed work, all roadway shoulders, slopes, ditches and berms shall be restored to their original condition. The CONTRACTOR E..,hall noti fy the Rai lroad Company or Highway Department of his construction schedule not less than five (5) days prior to commencing the work wi thin the right--of -way. The CON'I'RAC'l'OR shall conform to the requirements of the Railroad Company or Highway Department as to details of construction methods and time of construction. Ii' . Sani tary Sewers Sanitary Sewer Facilities shall be provided to adequately service the subdivision and conform with the City Sewer Plan. 1. All sewer pipe shall be of the fallowing: a.Ol Material - Clay pipe for sanitary sewers shall be either standard strength, glazed or unglazed, conforming to current A.S.T.M. Destignation C700 (Latest Revision) Or extra strength, glazed or unglazed, conforming to current A.S.T.M. Destignation C700 (Latest Revision), All clay pipe twelve (12~ inches is diameter and smaller shall be extra strength. All clay pipe eight (8) inches in diameter and larger shall be furnished in five (5) foot nominal laying lengt:hs, except for specials and fittings. ..Toint, material for clay pipe shall conform to the current requirements of A.S.T.M. Designation C425. a.02 Clay Pipe Installation - Pipe shall be installed in com-- pliance with current A.S.T.M. Designation C12. Pipe shall. be laid on prepared subgrade or embedments wit.h bell holes excavated. The laying of pipes :3hall commence at t_he lowest point. so that the spigot ends point. in the direction of 1 flo"!. All pipes shall be laid wi t11 ends abbating and true to line and grade. The pipe'S shall be matched so that when laid, they will form a sewer with a smooth, uniform invert. a.03 :embedment and Encasement 'There shall be five classes of embedment: Class 1. - Earth Embedment Class 2 - Gravel Embedment Class 3 -. Concrete Embedment Class 4 - Concrete Embedment Class 5 - Concrete Encasement (See Detail at end of Section F'. Sanitary Sewers P art I.) The class of embedment will be recommended by the City Engineering firm upon reviewal of plans before const:ruction of lines. I. _S'=-@.~~~ I fa .L CIa ~l?__~_~@J2~_9.rJl.~..D_t: Gravel for Class 2 Embedm(:,nt: shall consist of washed or screened gravel, ~-inch to ~-inch in slze, or pea gravel that is retained on liB-inch mesh but passes the S/8-inch mesh. Washed, screened or pea gravel shall be used in either earth or rock trench, where Class 2 Embedment is designated. 2. Concrete Ernbed_l!!en_.t_....:~lJd Encas~meIl.t Concrete embedment and enCi.1sement shall have a minimum cornpress~ve strength of 2,000 pounds per square inch at 28 days. Dry mix will not be permitted. The con- crete cushion portion of the embedment or encasement will be mixed moist or damp to give a slump or not more than one (1) inch. Concrete for the sides and top, if specified, shall be mixed to obtain' a slump of not less thah one (I) inch nor more than three (3) inches. After pipe joints are completed, the voids at the joints shall be filled with concrete, and the embedment shall be brought up to proper grade. Where concrete is placed over or along the pipe, it shall be placed in such manner as not to damage or injure the joints or dis- place the pipe. A cleavage line between the base concrete and the side embedment concrete will not be tolerated. Backfilling shall be done in a careful manner and at such time, after concrete embedment or encasement has been placed, as not to damage the concrete in any way. 3. Granular Material Granular material shall be hand placed to a depth of not less than twelve (12) inches over the top of the pipe, where designated on the plans. Granular material shall consist preferably of a free flowing material like sand or mixed sand and gravel, free from lumps large stone, clay and organic materials. Granular material shall also include rock cuttings from a ditch- ing machine (preferably wheel-type), provided that the largest chips shall have at least an average dimension in one place less than one-half inch (~"). Only if approved by the enigneer, good, sound eart:h may be used in lieu of granular material for backfill over the pipe. Good, sound earth is defined as gravel, sand, sandy loam or loam, free from excessive clay. If, when the material is damp and pressed into a tight ball in the hand and fingers are relaxed_ the material crumbles freely, the material will be considered as not having an excessive clay content. Good, sound earth will be allowed only if sand or rock cuttings are not present on the project. a.04 Inf il tration Test - TI1e total seepage and infiltration of ground water as determined by test shall in no case exceed 250 gallons per 24 hours per inch of diameter per mile of pipe. An infiltration test or tests shall be made on all sections of all sewer construction before placing the same in service and before any connections are made to other sewers, and if the quant,ity of infil- tration into the sewer or sewers is in excess of the maximum quantity as specified abo\'e, the joints shall be repaired or the sewer relaid if necessary, or other remedial construction shall be performed by and at the expense of the Developer, in order to reduce the quantity of ground water infiltration to an amount within limits as specified. In the making of all tests the Developer shall furnish the required equipment and labor and do the necessary pmnping under the direction of the Engineer and tests may be repeat_ed until each sewer individually meets the specifications as to quantity of infiltration as set out above. The City will not furnish water and the necessary connections to mains or fire hydrants~ however, if water is not. readily available, the Developer shall haul or pump necessary water to make the test. Test can be made by one of five methods as directed by the Engineer, except that all sections placed by boring, jacking or tunnelling shall be subjected to an exfiltration toe st. 1. Usinq Existinq_!i_!gl~~.r~Q_unsLv-l~.!_~E v.."'here the natural qrounc3 wdl er, after well points ~re removed, is above the top of the pipe for a section, the flowing of water in the pipe can be measured and tbe rate of seepage and infllt.ration measured for the section so submerged. 'rhree readings or measurements will be taken over a period of one (1) rninute and the average will be uf:~ed t:o determine the rate of infiltra- tion. 2. FloodinsL"~ Spe.ci!_:L~L0~S-:.!:1.0l} Backfill will be brought up to at least a foot over pipe to be tested for a distance of 200 feet or more. More cover may be required on larger pipest.o prevent the pipe from floating out of grade. DcU11S or dikes are placed tightly around pipe at either end and the ditch filled with water t.O an average dept. of four (4) feet over the pipe. Flow at the lower end is measured for the section so submerged. 'Three readings or measure- mentswill be taken over a ~riod of one (l) minute and the average w.lll be uE3ed to determine the rate of infilt.ration. "3. Exfi 1 trdt:ion A section of pipe below a rnanhole is bulkheaded at either end with a 6" pipe is set in d vertical position. A 2" vent: pipc: is inserted in lower encj and extended up-- ward four (4) feet. The 6" pipe is filled with water, fill.ing the sewer line until <111 air iE) forced out through the ven t tube, '1-Then the W<lter levels are level in t:he 2" ane] 6" pipe~3, mea~.;ure the drop in t"he 6" due to exfiltration over a specific time and cal- culate the lo,,;s of water due to exfiltration. Reduce this illnount by twenty-five percent (25%) to obtain equivalent infiltration. Conditions encountered in construction may vary this procedure slightly, but essentially this method shall be used. 4. Air Testinq Prior to air testing the pipe shall be visually inspected to determine collapsed or crushed pipe. After visual inspection the section to be tested shall be cleaned and flushed. After flushing, all pipe outlets in the test section shall be plugged and each plug shall be suitably and securely braced. (1) Constant Pressure: Add air slowly until the pressure in the test section reaches 3.0 pounds per > square inch gauge. Maintain the 3.0 psig pressure until the air in the system reaches the temperature of the pipe. (Approximately two minutes.) The volume of air leaked from the test section shall be measured by a rotameter placed in the system. The maximum rate of air loss for acceptance shall not exceed 0.003 cubic feet per minute per square foot of interior pipe surface, or 2.0 c.f.m. minimum when subjected to a constant pressure of 3.0 psig. For each foot of water table elevation above the invert of the pipe under test, the allowable loss shall be reduced six percent. (2) Time Pressure Drop: Add air slowly to the portion of the pipe under test until the internal air pressure is raised to 4.0 pounds per square inch gauge. Maintain the internal pressure at 4.0 psig, by adding air until the air temperature inside the pipe under test has stabilized. (Approximately two minutes.) At the end of the two minute period disconnect the air supply. When pressure decreases to 3.5 psig, start stop watch. Determine the time in seconds that is required for the internal air pressure to reach 2.5 psig. The amount of air loss shall then be determined from the pipe size, length of test section and time in seands and compared with the time required by specification as shown in table at back of this section. (3) Safety Provisions: Plugs used to close the sewer pipe for either air or exfiltration testing must be securely braced to prevent the unintentional release of a plug which can become a high velcity projectile. Gages, air piping manifilds and valves shall be located at the top of the ground. No one shall be permitted to enter a manhole where a plugged pipe is under pressure. (4) Test Equipment: The test equipment used with either method of air pressure testing shall be certified as satisfactory by the Engineer at the beginning of a project. The inspector may at any time require a cal- ibration check of the instrumentation used. (5) The Contractor shall perform the air testing in strict accordance with the manufacturer's instru- ctions for the equipment used. In no case will air testing be allowed for the 42-inch diameter pipe. b.01 Polyvin1y Chloride pipe for sanitary sewers shall have a minimum thickness SDR of 35. Joints for the piping system shall be sealed with a rubber ring gasket, and shall be of a composition and texture which is resistant to common ingredients of sewage, industrial wastes including oils and ground water, and which will endure permanently under the con- ditions likely to be imposed by this use. The joint, when assembled, must be able to withstand an hydr pressure internally of at least 10 psi. b.02 Pipe Installation and Field Testing - Pipe shall be installed in full compliance with the Recommended Practice for "Underground Installation of Flexible Thermoplastic Sewer Pipe," ASTM Designation D 2321 The bedding and haunching material shall be Class II - 1/4 to 3/4 inch graded angular stone as per ASTM Desig- nation D 2321-72. In addition to the construction and testing procedures outlined in other sections of the specifications, the Developer shall be required to install the pipe in such a manner so that the deflection of the pipe shall not exceed 5% and the material sur- rounding the pipe shall be compacted to not less than 90% Proctor. The area requiring compaction shall in- clude the bed and side fill material and also the material placed above the pipe for a distance of 12- inches over the top of the pipe. The City may require up to 10 random compaction tests to be completed by an approved independent laboratory. If any of these tests indicate that the material has not been compacted to the required density, the Developer shall recompact said material. The City shall then have the right to require additional compaction tests to insure that this or other material is compacted to the proper density. b.03 Final Acceptance - Maximum deflection of the pipeline under load shall be limited to 5% of the internal pipe diameter. Pipe exceeding this deflection shall be considered to have reached the limit of their service- ability. Prior to expiration of performance bond, the pipeline shall be measured for deflection by an inde- pendent testing laboratory acceptable to the City, at the expense of the Developer. All pipe exceeding 5% deflection, and all other related work and material, shall be replaced by the developer. Testing shall be conducted by means of passing a mandril, as approved by the City, from one end of the line to the other. If the testing procedures as listed above, indicate that the pipe deflection exceeds 5%, that portion will be considered as a failure, and developer will be required to replace pipe at developers expense. Infj 1 tration and (~xfi1 trdt ion t efJt.s uS described in paragraph a.04, section on Clay Pipe Sanitary Sewer, shall also apply to the Polyvi nly Cllloride Sewer Pipe. b.03 Embedment Detail eC.
