(A) Local utilities shall be contacted to verify construction plans and to make arrangements to disconnect all utility services, where required to undertake the construction work. The utility services shall later be reconnected. The work shall be scheduled so that there is minimum inconvenience to local residents. Residents shall be provided proper and timely notice regarding disconnection of utilities.
(B) The construction right-of-way shall be cleared only to the extent needed for construction. Clearing consists of removal of trees which interfere with construction, removal of underbrush, logs, and stumps, and other organic matter, removal of refuse, garbage, and trash, removal of ice and snow, and removal of telephone and power poles, and posts. Any tree which will not hinder construction shall not be removed, and shall be protected from damage by any construction equipment. Debris shall not be burned, but hauled for disposal in an approved manner.
(C) The public shall be protected from personal and property damage as a result of the construction work.
(D) Traffic shall be maintained at all times in accordance with applicable highway permits. Where no highway permits are required, at least one-half of a street shall be kept open for traffic flow.
(E) Erosion control shall be performed throughout the project to minimize the erosion of soils onto lands or into waters adjacent to or affected by the work. Erosion control work shall be implemented following the guidance provided in the New York State Guidelines for Urban Erosion and Sediment Control of the latest revision. If the project is large enough to require a state pollutant discharge elimination permit (SPDES) for the storm water runoff from the construction activity as required by NYSDEC regulations, a storm water pollution prevention plan shall be prepared and filed with the village and a Notice of Intent (NOI) shall be filed with NYSDEC prior to any work be completed.
(F) The trench shall be excavated only wide enough for proper installation of the water pipe and appurtenances. Allowances may be made for sheeting, de-watering, and other similar actions to complete the work. Roads, sidewalks, and curbs shall be cut, by sawing, before trench excavation is initiated.
(G) Under ordinary conditions, excavation shall be by open cut from the ground surface. However, tunneling or boring under structures other than buildings may be permitted. Such structures include crosswalks, curbs, gutters, pavements, trees, driveways, and railroad tracks.
(H) Open trenches shall be protected at all hours of the day with barricades.
(I) Trenches shall not be open for more than 50 feet in advance of pipe installation nor left unfilled for more than 50 feet in the rear of the installed pipe, when the work is in progress, without permission of the Superintendent. When work is not in progress, including over night, weekends, and holidays, the trench shall be backfilled to ground surface.
(J) The trench shall be excavated as necessary to allow for the final design pipe line and grade. When unsuitable soils are encountered, these shall be excavated and replaced with select materials.
(K) Ledge rock, boulders, and large stones shall be removed from the trench sides and bottom. The trench shall be over-excavated at least 12 inches for five feet, at the transition from rock bottom to earth bottom, centered on the transition.
(L) Maintenance of grade, elevation, and alignment shall be done by some suitable method or combination of methods approved by the Superintendent. All water mains and extensions shall be installed with a minimum depth of earth cover of four and one-half feet, unless specifically directed by the Superintendent.
(M) No structure shall be undercut unless specifically approved by the Superintendent.
(N) Proper devices shall be provided, and maintained operational at all times, to remove all water from the trench as it enters. At no time shall the water line be used for removal of water from the trench.
(O) To protect workers and to prevent caving, shoring and sheeting shall be used, as needed. Caving shall not be used to backfill the trench. Sheeting shall not be removed but cut off no lower than one foot above the pipe crown and no higher than one foot below final grade, and left in the trench, during backfill operations.
(P) The pipe barrel shall be adequately supported, along its entire length.
(Q) When the material encountered at grade in the trench is unsatisfactory to support the pipe or is otherwise harmful in the judgment of the Superintendent, the unstable or unsuitable soils shall be removed and replaced with select material or bedding stone.
(R) Ductile iron pipe shall be laid in accordance with AWWA Standard C600. Unless conditions require bedding as determined by the design engineer or the Superintendent, the trench shall have a flat bottom of sound earth which shall provide the pipe good bearing for its full length. Bell holes shall be hand excavated to allow the pipe to be supported for its full length. If the trench is in rock, the pipe shall be installed with a minimum of six inches of clean, washed No. 1 stone bedding beneath the entire length of the pipe barrel.
(S) If PVC pipe is approved for the work, it shall be installed in accordance with AWWA Standard C605. The trench shall be over excavated to allow at least six inches of clean washed No. 1 stone bedding beneath the entire length of the pipe barrel.
(T) In the case of PVC pipe, or in a rock trench condition, clean, washed No. 1 stone bedding shall be placed over the laid pipe to a depth of at least six inches. Care shall be exercised so that stone is packed under the pipe haunches. Care shall be exercised so that the pipe is not moved during placement of the crushed stone.
(U) Clean earth fill free of debris and any stones larger than four inches shall be hand placed and compacted to a depth of at least 12 inches over the top of the pipe bell to provide proper pipe embedment prior to machine backfilling being allowed to begin.
(V) The remaining portion of the trench above the pipe embedment shall be backfilled in one foot lifts which shall be firmly compacted. Compaction near/under roadways, driveways, sidewalks, and other structures shall be done with select backfill compacted to 95% of the maximum moisture-density relationship, as determined by ASTM Specification D698, Method D. Ice, snow, or other frozen material shall not be used for backfill.
(W) All main extensions shall be of such length as to provide access to each premises to be served and shall be constructed across the entire frontage of the lot(s). The applicant shall construct the water service connections for each parcel within the approved development or extension.
(X) Prior to beginning installation of the water mains and appurtenances, the applicant shall provide the following:
(1) Name of the contractor, including an address and phone number, proof of insurance, who will installing the water mains and appurtenances;
(2) Shop drawings indicating that all materials utilized meet village specifications;
(3) Minimum five business days advance written notice of the starting date of construction.
