SECTION 3 – STORMWATER <br />34 <br />A sediment filter shall be attached to the end of the dewatering discharge pipe. The sediment filter <br />shall be monitored and changed as necessary. The discharge points for the dewatering system shall <br />be approved by the City Engineer prior to commencing construction. <br />3-3.3 (e) STORM SEWER SYSTEM INSTALLATION <br />3-3.3 (e) (i) INSPECTION FOR DEFECTS <br />Before installation, the pipe shall be inspected for defects. Material found to be defective before or <br />after laying shall be replaced with sound material. <br />3-3.3 (e) (ii) CARE OF PIPE <br />Handle pipe and accessories so as to ensure delivery to the trench in sound, undamaged condition. <br />Particular care shall be taken not to damage the pipe coating or lining. If the coating or lining of <br />any pipe or fitting is damaged, it shall be repaired immediately. <br />No other pipe or material of any kind shall be placed inside a pipe or fitting after the coating has <br />been applied. Pipe shall be carried into position and not dragged. Use of pinch bars and tongs for <br />aligning or tuning pipe will be permitted only on the bare ends of the pipe. <br />The interior of pipe and accessories shall be thoroughly cleaned of foreign matter before being <br />lowered into the trench and shall be kept clean during laying operations by plugging or other <br />approved method. <br />3-3.3 (e) (iii) PIPE JOINTS <br />Prior to making pipe joints, clean and dry all surfaces of pipe joints and jointing material. Use <br />lubricants, primers, adhesives, and similar materials as recommended by the manufacturers. Place, <br />fit, joint, and adjust the jointing materials or factory fabricated joints as recommended by the <br />manufacturer to obtain the degree of water tightness required. As soon as possible after the joint is <br />made, place sufficient backfill material along each side of the pipe to resist forces that might tend <br />to move the pipe off line and grade. <br />3-3.3 (e) (iv) PIPE LAYING <br />1.) Pipe and accessories shall be carefully lowered into the trench by means of derrick, ropes, <br />belts, slings, or other authorized equipment. Under no circumstance shall any sewer-line <br />materials be dropped or dumped into the trench. Care shall be taken to avoid abrasion of <br />the pipe coating. <br />2.) Except where necessary in making connections with other lines or as authorized by the Engineer, <br />pipe shall be laid with the bells facing in the direction of laying.
