The protection of life and property and all liability for blasting shall be placed solely on the person or persons conducting the blasting operation. The hours of blasting shall be in accordance with the permit of the local authority. 6.11 DEWATERING All pipe trenches or structure excavation shall be kept free from water during pipe laying and other related work. The method of dewatering shall provide for a completely dry foundation at the final lines and grades of the excavation. Dewatering shall be accomplished by the use of well point, sump pumps, rock or gravel drains placed below subgrade foundations or subsurface pipe drains. All water shall be disposed of in a suitable manner without being a menace to public health or causing public inconvenience. No water shall be drained into other work being completed or under construction. The dewatering operation shall continue until such time as it is safe to allow the water table to rise in the excavations. Pipe trenches shall contain enough backfill to prevent pipe flotation. When pipe is installed in a casing or tunnel longer than thirty (30) pipe diameters, the pipe inside the casing or tunnels shall be secured so flotation does not occur when the pipe is empty... - Water shall not be allowed to rise until any concrete has set and the forms have been removed. Water shall not be allowed to rise unequally against unsupported structural walls. 6.12 SELECT PIPE BEDDING When indicated on the plans or drawings or when, in the opinion of the District, select bedding material is required, preparation and installation shall be as follows: h:u04vw-cv\mgs%20spm.9n-1r3Iro7 Water Specifications 23 A. Installation of Bedding and Pipe After completion of the trench excavation and proper preparation of the foundation, six inches (6") of bedding material shall be placed on the trench bottom for support under the pipe. Bell holes shall be dug deep enough to provide a minimum of two inches (2"}-of clearance between the bell and bedding material. All pipe shall be installed in such a manner as to insure full support of the pipe barrel over its entire length. After the pipe is adjusted for line and grade, and the joint is made, the bedding material shall be carefully placed and tamped under the haunches of the pipe and in the previously dug bell holes. Refer to details in the Specifications for additional information. Tamping -is -herein defined as the act-of placing approved bedding material under the haunches of pipe, paying particular attention. to voids, bell hole, and sling holes. The purpose of tamping is to ensure uniform support for the pipe. For ductile iron, polyvinyl chloride (PVC) and steel pipe the limits of bedding shall be from six inches (6") below the bottom of the pipe to twelve inches (12") above the top of the pipe. Approved backfill may then be installed to the ground line. B. Bedding Material The bedding material shall be clean and free of corrosive properties and shall conform to the gradation limits specified in Chapter 5 Material Specifications. 6.13 BACI FILL AND COMPACTION Backfill shall be consolidated and/or compacted by vibrating, tamping or a combination thereof, to the satisfaction of the appropriate controlling authority; however, the District shall require that in all instances where the trench is within limits of pavement, shoulders of roads, sidewalks or major improvements compaction of predominately cohesive soils shall not be less thadi* i?

It is expected that the trench excavation will provide suitable backfill material. Wet, soft or frozen material, asphalt and concrete chunks, cinders, ashes, refuse, vegetable or organic material, boulders, rocks or other deleterious substances shall not be used for backfill. If the excavated material is not suitable for backfill, as determined by the District, suitable material shall be hauled in and utilized, and the rejected material hauled away and disposed of properly. All trenches shall be backfilled and compacted from the bottom of the trench to the centerline of the pipe, with 3/4" screened rock or other approved material. Bedding material shall be tapped and compacted around and under pipe. Backfilling materials shall be deposited in the trench for its full width on each side of the pipe, fittings and appurtenances simultaneously.
