It is further agreed that any remedial action contemplated as hereinabove set forth shall be at Contractor's expense. 23.

Estimates of residential sewage contribution shall be based on 100 gallons per capita per day average flow. Peak factors are determined by population. Example: Peak Flow = 100 gal./cap. x P.F. x population. Minimum residential population density shall be figured on a basis of 2.5 persons per house, 6 houses per acre, and 70 percent of total land area developed as residential, unless detailed analysis of the area to be served indicates differently. Institutional, Commercial and Industrial sewage contribution estimates shall be reviewed with the Water Utilities Department. 301-3.0 Hydraulic Design: The minimum velocity at the design flow rate shall be 2.0 feet per second. Maximum allowable velocity shall be 10 feet per second. Where actual flow will be much below normal for several years, the minimum velocity shall be achieved by suitable grades at the partial design flow rate. Care shall be taken to design invert elevations at manholes in such a manner that the energy gradient is consistently falling in the direction of flow. 301-4.0 Design Details: Sanitary sewer mains shall be 6 inch diameter or larger. Service connections shall be 4 inch diameter or larger. The following minimum grades shall apply: When pipe is flowing half full. Sewer Diameter Minimum Grade (percent) N=0.013 N=0.001 4 inch 2.0 or 1 /4 inch per foot 6 inch 0.60 0.30 8 inch 0.40 0.22 10 inch 0.28 0.18 12 inch 0.22 0.14 15 inch 0.15 0.10 18 inch 0.12 0.08 Manholes shall be a minimum of 48 inch diameter and shall be provided at every change in direction, grade, or connection with other sewer main; maximum spacing shall be 500 feet for lines 15 inches or smaller, or 600 feet for lines 18 inches or larger. Sewer lines shall be straight and not curved between manholes both in line and grade. Cleanouts on sewer main line will not be permitted. Drop manholes shall be provided for a sewer entering a manhole at an elevation 30 inches or more above the manhole invert. Where the difference in elevation is less than 30 inches, the invert shall be filleted to prevent solids deposition. Sewer main shall ordinarily have a minimum of 4 feet of cover to finished ground surface. Where this will provide less than 5 feet of elevation difference between the finished lot grade at building line and the top of the sewer main, it shall be indicated on the plans that the lot is served by a "shallow sewer" and appropriate elevation information shall be given. Where pipe has less than 4 feet of cover, provisions shall be made to protect the pipe from impact loading when located in street. Tees shall be provided in the sewer main for service connections at each lot or building site. These tees shall ordinarily be located 5.0 feet from the centerline of the lot. Riser connections may be installed. Sewers constructed or extended to serve an end lot shall be constructed across the entire front (or rear) of the lot being served and terminate in a manhole, unless otherwise approved by the Water Utilities Department in writing. Manholes shall be stabbed out with suitable size pipe wherever future extension of the sewer is anticipated. v�z 301-5.0 Location Details: Unless approved otherwise by the Water Utilities Engineering Department, sanitary sewer mains shall be located five (5) feet east of the centerline of north -south alleys or streets. In east -west alleys or streets the sanitary sewer main shall be typically located five (5) feet south of the centerline. Where necessary to locate the sanitary sewer main along back lot lines or in other remote areas, the maintenance manholes shall be located to provide reasonable access for maintenance crews and equipment. 301-6.0 Relation to Water Mains: Sewers shall be located a minimum of 9 feet horizontally from existing or proposed water mains (centerline distance). Where sewer lines cross water mains, the sewer pipe shall be a minimum of 18 inches clear distance vertically below the water main. If this clear distance is not feasible, the crossing must be designed and constructed so as to protect the water main. Minimum protection shall consist of the installation of an impervious and structural sewer. For example: a. One length of ductile iron pipe at least 18 feet long centered over the water main. Joints between the sewer pipe and this joint of ductile iron pipe shall be encased in a concrete collar at least 6 inches thick and extending at least 12 inches either side of each of the joints. b. Vitrified clay sewer pipe with concrete encasement which is integrally reinforced with wire mesh. Encasement shall be at least 6 inches thick and shall extend a distance of 10 feet either side of the water main. In all cases, suitable backfill or other structural protection shall be provided to preclude settling and/or failure of the higher pipe. 301-7.0 Easements: When the Water Utilities Department determines it is not feasible to construct a public sanitary sewer in a dedicated street, the installation may be made in an easement or right -of- way. The conditions under which such an exception will be allowed will be determined for each individual case.

Pipe shall be placed on the site of the work parallel with the trench alignment and pipe with bell ends shall be placed with the bell ends facing in the direction in which the work will proceed. The pipe, fittings, and accessories shall be placed along the site in such a manner as to be kept as free as possible from dirt, sand, mud, and other foreign matter. Pipe Laying Alignment and Grade: All pipe shall be laid to the alignment as established on the ground by the Engineer. Where grade is being maintained, as shown on the plans, the use of batter board or laser beam will be required to fine grade the trench. Whenever it is necessary to deflect pipe from a straight line either in a vertical or horizontal plane to avoid obstructions, to plumb valves or where vertical or horizontal curves are shown or permitted, the degree of deflection recommended by the manufacturer of the particular kind of pipe being laid and the degree of deflection shall be approved by the Engineer. Field cuts on concrete pipe shall be made at all points where, in the opinion of the Engineer, it is necessary to preserve alignment or proper stationing for field connections. Proper care shall be taken _ to preserve the interior and exterior linings. After the spiral winding has been exposed, the winding shall be tack welded before being cut. In cutting the spiral winding sufficient length shall be allowed to permit a later winding of at least one-half turn on the bell or spigot ring. Where steel cylinder pipe r 3 is cut, the work shall be done in such a way as to allow a snug fit with the bell or spigot ring. A continuous weld shall be run on both the inside and the outside of the ring. The free end of the spiral shall then be wrapped around the ring and its end shall be welded to the ring by running a weld along each side of the rod for a distance of at least six inches. The entire cutting operation shall be done under the direction of a representative of the pipe manufacturer. Whenever the deflection in a joint exceeds the maximum deflection recommended by the manufacturer, the Engineer may require that the joint be welded. Joints on pipe installed in encasement pipe shall be tack welded or completely welded. Manner of Handling Pipe and Accessories into Trench: After the trench grade has been completed, all bell holes dug and the grade inspected, the pipes and accessories may be placed in the trench. All pipe, fittings, and valves shall be carefully lowered into the trench piece by piece by means of derricks, ropes, or other suitable tools or equipment, in such a manner as to prevent damage to the material in any way. Under no circumstance shall pipe or accessories be dropped or dumped into the trench. Cleaning and Inspection: Before lowering into the trench, the pipe shall be again inspected for defects and cast iron pipe while suspended shall be lightly hammered to detect cracks. Any defective, damaged, or unsound pipe or other incidental materials shall be rejected. All foreign matter or dirt shall be removed from the inside of the pipe, bells, spigots, or parts of the pipe used in forming the joint before the pipe is lowered into the trench; and it shall be kept clean by approved means during and after laying. The open end of the pipe in the trench shall be plugged when pipe is not being laid. Laying and Jointing Concrete Pressure Pipe: Just before making the joint, the gasket and the inside surface of the bell shall be lubricated with film of soft vegetable soap compound (flax soap) to facilitate telescoping the joint. The rubber gasket shall be stretched uniformly as it is placed in the spigot groove to insure a uniform volume of rubber around the circumference of the groove. Metal spacers of proper thickness shall be held on the inside shoulder of the bell to provide the proper space between abutting ends of 27 inch and larger pipe. The joint shall be telescoped by pulling directly along the center line of the pipe so that the spigot enters squarely into the bell. After the spigot has been telescoped into the bell, the bell end of the pipe being laid shall be moved in accordance with the plans to secure proper grade and alignment. After the joint is in place, a thin metal feeler gauge shall be used to check the position of the rubber gasket around the circumference of the joint. After the spigot has been telescoped into the bell, the joint checked and found satisfactory, a burlap wrapper shall be placed around the pipe covering the joint. The burlap -type wrapper shall be hemmed at each edge to allow threading with a steel strap to securely fasten the wrapper around the pipe by means of a stretcher and sealer. The length shall be that required to encircle the pipe, leaving enough space between the ends at the top to allow the cement mortar to be poured. The entire joint shall be poured with cement mortar and rodded or agitated to eliminate voids and settlement. Any joint showing shrinkage or excessive cracking shall be cleaned and remade. In hot weather, additional measure may be required to obtain the best quality of joint, such as additional wet burlap, curing membrane, or immediate careful and well -controlled backfilling of the joint with damp earth. L Where size permits, the inside joint recess shall be filled from the inside with mortar and finished off smooth with the inside of the pipe by hand troweling after the pipe has been backfilled. The inside joint recess on pipe smaller in diameter shall be filled by buttering the bell end with mortar No Text prevent damage. Under no circumstances should the pipe or accessories be dropped into the trench. All foreign matter or dirt should be removed from the pipe interior. Pipe joints should be assembled with care to the depth recommended by the manufacturer. 600-3.6 Backfillin� All trenches and bell holes for all types of pipe, valves, and fittings regardless of the location shall be backfilled with selected backfill material free from rocks, boulders, or other unsuitable material. The backfill material shall be thoroughly compacted with mechanical or hand tamps to midpoint of the pipe. In existing paved streets the backfill above the midpoint of the pipe shall be compacted with mechanical or hand tamps to 7-1/2 inches below existing paving. In areas where paved streets are not existing the backfill to a point twelve (12) inches above the pipe shall be placed by hand and shall be carefully selected material free of rocks, boulders, clods, organic material, or other debris and lightly compacted prior to placing remaining backfill. The balance of the backfill may be placed in the ditch by hand or by mechanical equipment. No backfill material shall be dropped directly on exposed pipe. The backfill shall be consolidated by forcing water into the backfill at two (2) feet above the level of compacted material until the water level rises to within eighteen (18) inches of the natural ground surface. Care shall be taken not to flood the ditch or saturate the pipe embedment. The water shall be forced into the backfill at location not more than ten (10) feet apart. Maintenance of Backfilled Trench: After the trench has been backfilled in the above method, the right-of-way shall be cleared of all rocks larger than one and one-half (1-1/2) inches in diameter and leveled so that the surface will have the same slope and appearance as it possessed before the Contractor began work. All surplus material shall be loaded and wasted at the Contractor's expense, at a location approved by the Engineer. The above shall include all excavated materials and all rocks or hard lumps which still remain after blading the area back to the original ground grade. Furrows which tend to gather after blading shall be removed, together with excavated material which has drifted or otherwise covered private property. As the construction work progresses, the contractor will be required to keep the jetting of the backfill and clean up just as close behind the pipe laying and backfilling as possible. Following the completion of the backfilling the Contractor shall maintain the street and trench surfaces, in a satisfactory manner until final completion and acceptance of the work. The maintenance to include blading from time to time as necessary, filling depressions caused by settlement, sprinkling to settle dust, brooming or flushing at the request of the Engineer and other work required to keep the streets and roads in satisfactory condition for traffic. The Contractor shall maintain and be responsible for all paving cuts until such time as City Forces shall repair cuts with asphalt. 600-3.7 Setting Valves, Valve Boxes and Fittings Valves and fittings shall be set at the locations shown on the plans or at locations as established by the Engineer, and shall be joined to the pipe in the manner heretofore specified for pipe installation. The valves and fittings shall be adequately blocked for thrust with concrete.

However, the consumer service lines from these utilities are not known. The Contractor will be required to locate all utility lines, including customer service lines, far enough in advance of the trenching to make proper provisions for protecting the lines and to allow for any deviations that may be required from the established lines and grades. The Contractor will not be allowed to disrupt the service on any utility lines except customer service lines, which may be taken out of service for short period of time provided the Contractor obtains permission from the Engineer and from the owner of the premises being served by the utility. The Contractor shall immediately notify the proper utility company of any damage to utility lines in order that service may be established with the least possible delay. Any damage to existing lines and 4 the repair of customer lines which are authorized to be cut shall be at his own expense, and as directed by an official representative of the utility company involved. All utility lines shall be properly supported to prevent settlement or damage to the line both during and after construction. The cost of supporting utility lines shall be included in the unit price bid per foot of pipe. Any permanent relocation of existing utility lines shall be done by the proper utility company without expense to the Contractor. Where pipes, conduits, or concrete curbs or gutters are encountered, the cost of tunnelling shall be included as a part of the cost of the pipe line. 600-3.9 Removing Pavement General: Wherever it is necessary to make cuts in existing pavements, sidewalks, driveways, or curbs and gutters, the cuts shall be made in such a manner as to cause the least possible damage to adjoining surfaces. Removal of Asphalt Paving: In removing asphalt pavement, the asphalt surface shall be cut along each side of the trench ahead of the trenching machine and the surfacing and base removed with the trenching machine as the trench is excavated. The width of surface removed by the Contractor is not to exceed the outside diameter of the pipe plus thirty-six (36") inches. Any areas removed or damaged in excess of the above widths will be charged against the Contractor's estimate at the estimated cost per square foot as determined by paving engineer for payment to the City for replacing the excessive width. No separate payment will be made for cutting and removing asphalt paving and _ caliche base, the cost of this work shall be included as a part of the cost of the pipe line complete in place. 3 Removal of Concrete Paving: Removal of any sidewalks, concrete pavement, concrete base, concrete curbs and gutters (where allowed) shall be made by cutting the concrete to a straight line on each side of the trench and removing the concrete ahead of the trenching. Normally, tunnelling will be required under curb and gutters. The width of surface removed by the Contractor of concrete paving is not to exceed the outside diameter of the pipe plus thirty-six (36") inches. Any areas removed or damaged in excess of the above widths will be charged against the Contractor's estimate at the estimated cost per square foot as payment to the City for replacing the excessive width. Care shall be taken to preserve any reinforcement encountered as well as possible. Cutting of steel reinforcement will be No Text tmJ allowed only at the approximate center of the pavement cut. Payment for removal of concrete paving shall be included in the unit price bid per foot of pipe installed. 600-3.10 Concrete Cradling and Blocking Where concrete cradling is used, the concrete shall conform to the concrete specifications. Before placing the concrete, all loose earth shall be removed from the trench. The concrete shall be placed in the trench by the use of chutes extending to within three (3) feet of the bottom of the trench and shall be deposited uniformly on each side of the pipe in such a manner as not to disturb the grade and alignment of the pipe. The concrete shall be of such consistency that is will flow without separation of the aggregates. At locations shown on the plans or as directed by the engineer, the contractor will be required to cradle the pipe or block the fittings. 600-3.11 Anchorage of Bends and Plugs, Etc. Concrete shall be used for blocking the pipe, plugs, and fittings and shall conform to the concrete specifications. The blocking shall be placed, as directed by the engineer, between solid ground and the fitting to be anchored: the area of bearing on pipe and on the ground in each instance shall be that required by the engineer. The blocking shall be so placed that the pipe and fitting joints will be assessable for repair. The soil bearing value for thrust backing shall be recommended by the pipe manufacturer, and in the absence of such recommendation, the allowable bearing value shall not exceed 3000 lbs. per square foot. 600-3.12 Hydrostatic Tests Pressure During Test: After the pipe has been laid, the line shall be subjected to a hydrostatic pressure test and leakage test. The line shall be tested at 50 p.s.i. pressure. Duration of Pressure Test: The duration of each pressure test shall be as directed by the engineer but shall not exceed for (4) hours. Procedure: Each valved section of pipe shall be slowly filled with water at the specified test pressure measured at the point of lowest elevation. Pressure shall be applied and maintained by means of a pump connected to the pipe in a satisfactory manner. The pump, pipe connection, and all necessary apparatus except meters shall be furnished by the contractor, and the contractor shall furnish all necessary labor for connecting the pump, meter, and gages. The water for filling and making tests on v these mains may be obtained at a location designated by the engineer. No charge will be made for water used for this purpose. As the line is being filled and before applying the test pressure, all air shall be expelled from the pipe. To accomplish this, taps shall be made, if necessary, at points of highest elevation. After the test, the taps shall be tightly plugged. During the time the test pressure is on the pipe, the line shall be carefully checked at regular intervals for breaks or leaks. Any joints showing appreciable leaks shall be repaired and any cracked or defective pipes or fittings shall be removed and replaced with sound material in the manner provided and the test shall be repeated until satisfactory results are obtained. Leakage Test: After all defects have been satisfactorily repaired and all visible leaks stopped, a leakage test shall be made on each valved section of the lines to determine the quantity of water lost by leakage. The contractor shall furnish all labor, material, and equipment (except meters) required for making the test. The leakage shall be determined by measuring the quantity of water supplied to each valved section of the lines, during the test period, when the various sections of the lines are under pressure. No pipe installation will be accepted until or unless the leakage as determined by above test is less than the amount set forth below. The allowable leakage (gallons per hour) shall not be greater than determined by the following formula: L = ND P 7400 L = Gallons Per Hour D = Nominal Pipe Diameter (in.) N = Number of Joints P = Test Pressure (PSI) If individual sections show leakage greater than the limits specified above, the contractor shall at his own expense locate and repair the defective joints until the leakage is within the specified allowance. 600-3.13 Sterilization of Pipe Lines The contractor shall furnish all labor, equipment and material necessary for the chlorination of the new pipe lines which shall be sterilized before being placed in service. The lines shall be sterilized by the application of the chlorinating agent. The chlorinating agent may be a liquid chlorine, liquid chlorine gas -water mixture, or a calcium hypochlorite solution, which shall be fed into the lines through a suitable solution -feed device, or other methods approved by the engineer. The chlorinating agent shall be applied at or near the point from which the line is being filled, and through a corporation stop or other approved connection inserted in the horizontal axis of the newly laid pipe. The water being used to fill the line shall be controlled to flow into the section to be sterilized very slowly, and the rate of application of the chlorinating agent shall be in such proportion of water entering the pipe that the chlorine dose applied to the water entering the line shall be at least 50 parts per million. The treated water shall be retained in the pipe lines for a period of not less than twenty- _ 3 four (24) hours. Samples shall be taken from the line and will be tested for bacteriologic growth by the Texas Department of Health Laboratory.
