Utility connections (sanitary sewer,watermain, and storm sewer) may require a permit from the City.3.The contractor shall verify the elevations at proposed connections to existingutilities prior to any demolition or excavation.4.The contractor shall notify all appropriate engineering departments and utilitycompanies 72 hours prior to construction. All necessary precautions shall be madeto avoid damage to existing utilities.5.Storm sewer requires testing in accordance with Minnesota plumbing code4714.1109 where located within 10 feet of waterlines or the building.6.HDPE storm sewer piping shall meet ASTM F2306 and fittings shall meet ASTMD3212 joint pressure test. Installation shall meet ASTM C2321.7.All RCP pipe shown on the plans shall be MN/DOT class 5.8.Maintain a minimum of 7 ½' of cover over all water lines. Where 7 ½' of cover is notprovided, install 2” rigid polystyrene insulation (MN/DOT 3760) with a thermalresistance of at least 5 and a compressive strength of at least 25 psi. Insulationshall be 8' wide, centered over pipe with 6” sand cushion between pipe andinsulation. Where depth is less than 5', use 4” of insulation.9.Install water lines 12” above sewers. Where the sewer is less than 12" below thewater line (or above), install sewer piping of materials approved for inside buildinguse for 10 feet on each side of the crossing.10.All watermain piping shall be class 52 ductile iron pipe unless noted otherwise.11.See Project Specifications for bedding requirements.12.Pressure test and disinfect all new watermains in accordance with state and localrequirements.13.Sanitary sewer piping shall be PVC, SDR-35 for depths less than 12', PVC SDR-26for depths between 12' and 26', and class 52 D.I.P. for depths of 26' or more.Sanitary sewer shall be Schedule 40 PVC where crossing over waterlines.14.Storm Sewer shall be Schedule 40 PVC where crossing over waterlines andconnecting to building services.C500UTILITY PLANLEGENDCABLE UNDERGROUND LINEFIBER OPTIC UNDERGROUND LINEELECTRIC UNDERGROUND LINEELECTRIC OVERHEAD LINETELEPHONE UNDERGROUND LINESTORM SEWER PIPESANITARY SEWER PIPENATURAL GAS UNDERGROUND LINEWATERMAIN PIPEDRAINTILE PIPEPIPE INSULATION, DETAIL 16/C700LIGHT POLE, BY ELECTRICALSTORM MANHOLEFLARED ENDCURB INLETCATCH BASINWATER SHUTOFFGATE VALVE & BOXHYDRANTSANITARY MANHOLEINV = XXX.XX* - TO BE COORDINATED OR VERIFIEDNWLNWLNWLNWLEXISTING WETLAND EDGENEW WETLAND EDGE
