Repair all visible leaks regardless of the amount of leakage. 4. Force Main Pressure Testing: All force mains shall be subject to pressure testing at 150 PSI. System Operating Pressure Test pressure Duration 50 PSI or less 100 PSI 2 hours Greater than 50 PSI 150 PSI or 2 2 hours times the operating pressure, whichever is greater. Allowable leakage on force mains shall be computed utilizing the standards for water loss in conformance with AWWA C600, the latest revision thereof. 5. Infiltration/Exfiltration Testing for Gravity Lines The allowable limits of infiltration or exfiltration for the entire system, or any portion thereof, shall not exceed a rate of 50 gallons per inch of inside pipe diameter per mile of pipe per 24 hours. No additional allowance shall be made for house service lines. Any part of or all of the system shall be tested for infiltration or exfiltration, as directed by the ENGINEER or as required by the County Manager or designee. The procedures and limitations for conducting infiltration/exfiltration tests shall be established at the pre- construction conference on a project-by-project basis. Air testing of gravity sewer mains may be required. All testing shall be run continuously for 24 hours, unless the County Inspector can visually verify that this test duration is not required due to the observed infiltration/exfiltration rate. The amounts of infiltration or exfiltration shall be determined by pumping water into or out Section 022501 COLLIER COUNTY LEAKAGE TESTS TECHNICAL SPECIFICATIONS Page 5 of 10 of calibrated drums, or by other methods approved by the Public Utilities Division, such as in-line V-notch weirs. Where infiltration or exfiltration exceeds the allowable limits specified herein, locate and repair the defective pipe, joints or other faulty construction at no additional cost to the COUNTY. If the defective portions cannot be located, remove and reconstruct as much of the work as is necessary in order to conform to the specified allowable limits. All visible leaks shall be repaired regardless of the amount of leakage. Provide all labor, equipment and materials required and conduct all testing required under the direction of the ENGINEER. a. Infiltration: Prior to testing for infiltration, the system shall be pumped out so that normal infiltration conditions exist at the time of testing. The cumulative results of the entire collection system results shall not be a satisfactory method for gauging infiltration compliance. Each sewer section between manholes must permit infiltration no greater than the maximum allowable, as specified above. b. Exfiltration: The exfiltration test, when required due to groundwater levels, will be conducted by filling the portion of the system being tested with water to a level 2 feet above the uppermost manhole invert in the section being tested. The cumulative results of the entire collection system results shall not be a satisfactory method for gauging exfiltration compliance. Each sewer section between manholes must permit exfiltration no greater than the maximum allowable, as specified above. 6. Low Pressure Air Testing Contractor shall conduct air testing in accordance with ASTM specifications: a. ASTM C-828—for clay pipes. b. ASTM C-924—for concrete pipes. c. ASTM F-1417 —for plastic pipes. When low pressure air testing of gravity sewer mains is specifically required, all testing shall be run continuously for 24 hours, unless the County Inspector can visually verify that this test duration is not required due to the observed infiltration/exfiltration rate. When air testing is specifically required, after completing backfill of a section of gravity sewer line, conduct a Line Acceptance Test using low pressure air. The test shall be performed using the below stated equipment, according to state procedures and under the supervision of the ENGINEER and in the presence of the County Manager or designee, with 48 hours advanced notice. Section 022501 COLLIER COUNTY LEAKAGE TESTS TECHNICAL SPECIFICATIONS Page 6 of 10 d. Equipment: (1) Pneumatic plugs shall have a sealing length equal to or greater than the diameter of the pipe to be inspected. (2) Pneumatic plugs shall resist internal bracing or blocking. (3) All air used shall pass through a single control panel. (4) Three individual hoses shall be used for the following connections: (a) From control panel to pneumatic plugs for inflation. (b) From control panel to sealed line for introducing the low- pressure air. (c) From sealed line to control panel for continually monitoring the air pressure rise in the sealed line. e. Procedure: All pneumatic plugs shall be seal tested before being used in the actual test installation. One length of pipe shall be laid on the ground and sealed at both ends with the pneumatic plugs to be checked. Air shall be introduced into the plugs to 25 psi. The sealed pipe shall be pressurized to 5 psi. The plugs shall hold against this pressure without bracing and without movement of the plugs out of the pipe. After a manhole-to-manhole reach of pipe has been backfilled and cleaned and the pneumatic plugs are checked by the above procedure, the plugs shall be placed in the line at each manhole and inflated to 25 psi. Low-pressure air shall be introduced into this sealed line until the internal air pressure reaches 4 psi greater than the average back pressure of any ground water that may be over the pipe. At least two (2) minutes shall be allowed for the air pressure to stabilize. After the stabilization period (3.5 psi minimum pressure in the pipe), the air hose from the control panel to the air supply shall be disconnected. The portion of the line being tested shall be termed "Acceptable", if the time required in minutes for the pressure to decrease from 3.5 to 2.5 psi (greater than the average back pressure of any ground water that may be over the pipe) is greater than the time shown for the given diameters in the following table: Section 022501 COLLIER COUNTY LEAKAGE TESTS TECHNICAL SPECIFICATIONS Page 7 of 10 Pipe Diameter In Inches Minutes 8 4.0 10 5.0 12 5.5 16 7.5 18 8.5 24 11.5 Time in Minutes = 0.472 D D = Diameter of pipe in inches In areas where ground water is known to exist, install capped pipe adjacent to the top of the sewer lines. This shall be done at the time of the sewer line is installed. Immediately prior to the performance of the Line Acceptance Test, the ground water shall be determined by removing the pipe cap, and a measurement of the height in feet of water over the invert of the pipe shall be taken. The height in feet shall be divided by 2.3 to establish the pounds of pressure that will be added to all readings. (For example, if the height of water is 11-1/2 feet, then the added pressure will be 5 psi. This increases the 3.5 psi to 8.5 psi, and the 2.5 psi to 7.5 psi. The allowable drop of one pound and the timing remain the same). If the installation fails to meet this requirement, determine the source of the leakage and repair or replace all defective materials and/or workmanship, all at no additional cost to the COUNTY. B. DEP approval is required to use reclaimed (IQ) water for flushing and pressure testing of irrigation mains and potable water mains. The requirements for submitting a request to DEP are available from the County PUED. 3.2 LEAKAGE TESTS FOR STRUCTURES A. Structure Leakage Testing: Perform leakage tests of manholes, wet wells, tanks, vaults and similar purpose structures before backfilling, by filling the structure with water to the overflow water level and observing the water surface level for the following 24 hours. 1. Make an inspection for leakage of the exterior surface of the structure, especially in areas around construction joints. 2. If visible leaks appear, repair the structure by removing and replacing the leaking portions of the structure, waterproofing the inside, or by other methods approved.

Where pipe joint deflections are used, do not exceed 80 percent of the maximum deflection limits shown in AWWA C600. Gravity systems shall contain no joint deflection. 1. Arrange miscellaneous pipelines, which are shown in diagram form on the Plans, clear of other pipelines and equipment. 2. Gravity systems shall not contain vertical dips greater than one and a half inches (1.5"). B. Code Requirements: Provide pipeline installations complying with AWWA C600 for iron pipe, AWWA Manual M11 for steel pipe, ASTM D 2774 for thermoplastic pressure piping, and as modified or supplemented by the Specifications. C. Pipe Laying - General: 1. Thoroughly inspect all pipe for damage and cleanliness. If found to be defective, tag, remove and replace pipe with satisfactory pipe or fittings at no additional charge to COUNTY. 2. Generally, lay all pipe with bells pointing ahead. 3. Carefully place all pipe, pipe fittings, valves and hydrants into trench by means of a derrick, ropes or other suitable tools or equipment in such a manner as to prevent damage and check for alignment and grade. 4. Make adjustments to bring pipe to line and grade by scraping away or filling in select fill material under the body of the pipe. 5. Wedging or blocking up the pipe barrel is not permitted. Section 330518 COLLIER COUNTY LAYING AND JOINTING BURIED PIPE TECHNICAL SPECIFICATIONS Page 4 of 12 6. Bring the faces of the spigot ends and the bells of pipes into fair contact and firmly and completely shove the pipe home. 7. As the work progresses, clean the interior of pipelines of all dirt and superfluous materials of every description. 8. Keep all lines absolutely clean during construction. 9. Lay pipelines accurately to line and grade. 10. During suspension of work for any reason at any time, a suitable stopper shall be placed in the end of the pipe last laid to prevent mud or other material from entering the pipe. D. Pipe Laying - Trenches: 1. Carefully lay all pipelines in trench excavations piece by piece using suitable tools or equipment on select fill bedding (refer to Utilities Standards and Procedures Ordinance, Section 9.1.2), concrete cradle or other foundations as shown, specified or ordered in writing. Prevent damage to materials, protective coatings and linings. 2. Do not dump or drop pipe or pipe materials into trench. 3. Properly secure the pipe against movement and make the pipe joints in the excavation as required. 4. Carefully grade and compact pipe bedding. 5. Bell Holes: a. Cut out bell holes for each joint as required to permit the joint to be properly made and allow the barrel of the pipe to have full bearing throughout its length. b. Thoroughly tamp bell holes full of select fill material following the making of each joint to provide adequate support to the pipe throughout its entire length. E. Other Foundations: Install pipelines laid on other types of foundations as specified for such other foundations or as ordered in writing. F. Field Cuts of Pipelines: For shorter than standard pipe lengths, make field cuts in a manner producing a cut square and perpendicular to the pipe axis. Remove any sharp, rough edges which otherwise might injure the gasket. G. Procedure for sealing cut ends and repairing field damaged areas of polyethylene lined pipe and fittings is as follows: Section 330518 COLLIER COUNTY LAYING AND JOINTING BURIED PIPE TECHNICAL SPECIFICATIONS Page 5 of 12 1. Remove burrs caused by field cutting of ends or handling damage and smooth out edge of polyethylene lining if made rough by field cutting or handling damage. 2. Remove oil or lubricant used during field cutting operations. 3. Areas of loose lining associated with field cutting operation must be removed and exposed metal cleaned by sanding or scraping. For larger areas, remove loose lining and dirt, then roughen bare pipe surface by scratching or gouging with a small chisel to provide an anchor pattern for the epoxy. It is recommended that the polyethylene lining be stripped back by chiseling, cutting, or scraping about 1 inch to 2 inches into well adhered lined area before patching. This ensures that all areas of undercutting have been removed. Be sure to roughen an overlap of 1 inch to 2 inches of polyethylene lining in area to be epoxy coated. This roughening should be done with a rough grade emery paper (40 grit), rasp, or small chisel. Avoid honing, buffing, or wire brushing since these tend to make surface to be repaired too smooth for good adhesion. 4. With area to be sealed or repaired clean and suitably roughened, apply a thick coat of a two-part coal tar epoxy (see County Approved Product List, Appendix F). The heavy coat of epoxy must be worked into the scratched surface by brushing. Mixing and application procedure for the epoxy must follow the epoxy manufacturer's instructions. 5. It is important that the entire freshly cut, exposed metal surface of the cut pipe be coated. To ensure proper sealing, overlap at least 1 inch of the roughened polyethylene lining with this two-part epoxy system. H. Ductile Iron Pipe Mechanical Joints: 1. Assembly: In making up mechanical joints, center the spigot in the bell. a. With a wire brush just prior to assembly of the joint thoroughly brush 8 inches outside of spigot and inside of bell with which the rubber gasket comes in contact. Remove all oil, grit, tar (other than standard coating) and other foreign matter from joint. b. Brush lubricant over the gasket just prior to installation. (Note: There is only one rubber gasket size for each diameter of pipe.) c. Press the gasket into place within the bell and move the gland into position, bolts inserted, and the nuts tightened finger tight. d. Tighten the nuts with a torque wrench so that the gland is brought up toward the pipe evenly. Torque wrenches shall be set as specified in AWWA C111. Spanner type wrenches not longer than specified in Section 330518 COLLIER COUNTY LAYING AND JOINTING BURIED PIPE TECHNICAL SPECIFICATIONS Page 6 of 12 AWWA C111 may be used with the permission of County Manager or designee. threads. Coat threads immediately prior to installation of nuts. f.e. Tighten all nuts 180 degrees apart alternately in order to produce equal pressure on all parts of the gland. 2. Torques: Apply the following range of bolt torques: Size Range of Inches Torque - ft. lbs 5/8 40 - 60 3/4 60 - 90 1 70 - 100 1-1/4 90 - 120 3. Remaking of Joints: If effective sealing is not obtained at the maximum torque listed above, disassemble and reassemble the joint after thorough cleaning. I. Ductile Iron Pipe Rubber Gasket Joints: 1. Assembly: In making up the rubber gasket joint, brush the gasket seat in the socket thoroughly with a wire brush and wipe the gasket with a cloth. a. Place the gasket in the socket with the large round end entering first so that the groove fits over the bead in the seat. b. Apply a thin film of lubricant (AWWA C600) to the inside surface of the gasket that will come in contact with the entering pipe. c. Brush the plain end of the pipe to be entered thoroughly with a wire brush and place it in alignment with the bell of the pipe to which it is to be joined. d. Exert sufficient force on the entering pipe so that its plain end is moved past the gasket until it makes contact with the base of the socket to make the joint. 2. Positioning: Before proceeding with backfilling, feel completely around the joint using a feeler gauge to confirm that the gasket is in its proper position. a. If the gasket can be felt out of position, withdraw the pipe and examine the gasket for cuts or breaks. Section 330518 COLLIER COUNTY LAYING AND JOINTING BURIED PIPE TECHNICAL SPECIFICATIONS Page 7 of 12 b. If the gasket has been damaged, replace it with a new one before re- installing the pipe. 3.
