106 SECTION 8 WATER DISTRIBUTION SYSTEM CONSTRUCTION PROCEDURES The following information covers water distribution system construction procedures and is applicable to all developments requiring water service from Charleston Water System. No deviation from these procedures will be allowed without the expressed written consent of Charleston Water System. A. GENERAL 1. Construction of water and wastewater systems to be turned over to Charleston Water System must be performed by a Charleston Water System Approved Contractor. The Approved Contractor lists for both Large Projects (those greater than $50,000) and Small Projects (those $50,000 and less) are available on our website. Requirements for being considered an Approved Contractor can be obtained by contacting the Assistant Director of Engineering and Construction by at benjamind@charlestoncpw.com or by telephone at (843) Prior to construction activities taking place, the Developer s Engineer shall coordinate in advance a Pre-Construction Meeting with the assigned Charleston Water System Construction Inspector. The Developer, Developer s Engineer, Approved Contractor(s), and Charleston Water System s Construction Inspector shall be in attendance at a minimum. 3. If any requirements for carrying out project construction are not met, Charleston Water System reserves the right to have the Developer s Engineer issue a STOP WORK ORDER. B. OPERATION OF CHARLESTON WATER SYSTEM VALVES AND HYDRANTS 1. Only Charleston Water System personnel shall operate Charleston Water System valves or hydrants unless otherwise directed or approved by Charleston Water System. 2. Approval for non-charleston Water System personnel to operate Charleston Water System valves or hydrants shall be determined on a caseby-case basis. 3. All hydrant and blow-off operations shall be done in a manner so that private property is not impacted and there shall be no flooding of streets or roadways or any other traffic problems created. EC-MGT-9 (Rev. 09/01/17) 8-1

107 C. HANDLING OF MATERIALS 1. Store rubber gaskets and polyethylene film under cover and out of direct sunlight. Do not store nuts, bolts, glands, and other accessories directly on the ground. Keep inside of pipe and fittings free of dirt and debris. 2. Keep valves off the ground and keep interior free of dirt and debris. Do not expose valve interior to direct sunlight. 3. Handle pipe so as to ensure delivery to the trench in sound, undamaged condition. 4. Carry pipe into position. 5. Use pinch bars, slings or tongs for aligning or turning pipe. 6. Use care not to damage pipe linings. D. TRENCH EXCAVATION This section is provided to outline most types of laying conditions, but is not intended to cover all special laying conditions or the Engineer s special requirements. 1. Trench excavation shall be made in open cut and true to the lines and grades shown on the plans, unless boring is necessary or required. Banks of the trenches shall be cut in vertical, parallel planes equidistant from the pipe centerline. The horizontal distance between such planes, or the overall width of trench, shall vary with the size of the pipe to be installed. See Details. 2. Bell holes for bell-and-spigot pipe shall be excavated at proper intervals so that the barrel of the pipe will rest for its entire length upon the bottom of the trench. Bell holes shall be large enough to permit proper installation of joints in the pipe. 3. When muck, quicksand, soft clay, swampy or other material unsuitable for foundations or sub-grade is encountered such material shall be removed and replaced with crushed stone. 4. After excavation, the area between the final pipe grade and the trench soil bottom shall be filled with crushed stone materials as required, compacted to proper grade, and made ready for pipe laying. 5. Debris encountered in trench excavation for water mains and other pipelines shall be removed for the overall width of trench which shall be as EC-MGT-9 (Rev. 09/01/17) 8-2

108 shown on the plans. It shall be removed to a depth of 6" below the bottom of the pipe for pipes smaller than 24" in size; 8" below the bottom of the pipe for pipes 24" to 36" in size; and 12" below the bottom of the pipe for pipes larger than 36" in size, if debris extends to such depth. 6. In all cases, materials deposited shall be placed so that in the event of rain, no damage will result to the work. 7. The sides of all excavations shall be sufficiently sheeted, shored and braced whenever necessary to prevent slides, cave-ins, settlements or movement of the banks and to maintain the excavation clear of obstructions. Maintain the walls of the excavation properly in place and protect all persons and property from injury or damage. Sheeting, shoring or bracing materials shall not be left in place unless as shown by the plans or permitted by Charleston Water System. All sheeting and bracing shall be left in place until the trench has been backfilled 1 above the top of the pipe. E. TRENCH BACKFILL 1. The backfilling of pipeline trenches shall be started immediately after the pipe work has been inspected. The initial backfill material, placed to a height of 1 above the top of the pipe, shall consist of approved backfill material free from organic matter and deleterious substances, containing no rocks or lumps over 2" in any dimension. It shall be carefully placed and compacted through compaction of entire area backfilled. 2. Backfill shall be deposited in 6" layers (before compaction) and thoroughly compacted with power tools to 95% of theoretical maximum density, modified Proctor ASTM-D Where pipe trenches are cut across or along pavement, the trenches shall be backfilled in accordance with applicable permits. 4. Backfilling around structures shall be done in the manner specified above for pipe trenches by power tamping for the full depth of cut from the bottom of the finished grade. 5. All backfilling shall be done in such a manner as will not disturb or injure the pipe or structure over or against which it is being placed. Any pipe or structure injured, damaged or moved from its proper line or grade during backfilling operations shall be uncovered, repaired, and then re-backfilled as herein specified. 6. All excavations suspected of not meeting compaction requirements shall be tested for conformance by a Charleston Water System approved testing lab. EC-MGT-9 (Rev. 09/01/17) 8-3

109 Tests shall be performed at the locations and depths directed by Charleston Water System. F. PIPE, VALVE, AND APPURTENANCE INSTALLATION 1. General a. Inspect pipe for damage. Remove damaged and unacceptable pipe. Keep interior and joint surfaces clean and free of foreign materials. Install a mechanical joint or push-on type ductile iron plug whenever work stops for a period of a day or greater. b. Replace pipe where any part of coating or lining is damaged. c. Lower pipe and accessories into trench by means of derrick, ropes, belt slings, or other equipment approved by the manufacturer. d. Do not dump or drop any of the materials into the trench. e. Except where necessary in making connections to other lines, lay pipe with the bells facing in the direction of laying. f. Rest the full length of each section of pipe solidly on the pipe bed, with recesses excavated to accommodate bells, couplings, and joints. g. Bell pipe using manufacture s approved leverage bar. Do not use machinery to bell pipe. Home line is to be clearly visible when pipe is joined. h. Do not lay pipe in water or when trench conditions are unsuitable for the work. Keep water out of the trench until jointing is completed. i. Re-lay pipe that has the grade or joint disturbed after laying. j. Install hydrants and valves in accordance with manufacturer s recommendations. See Construction Details k. Valves shall be carefully handled, cleaned and checked for operation prior to backfilling. Care shall be taken to ensure that no dirt, rock, or other obstacles that would interfere with the operation are left in the valve. Valves shall be installed in a position such that the plane of operation or rotation for the operating nut is parallel to the ground surface. EC-MGT-9 (Rev. 09/01/17) 8-4
