Designation:F230303(Reapproved 2015)Standard Practice forSelection of Gravity Sewers Suitable for Installation ofOptical Fiber Cable and Conduits1This standard is issued under the fixed designation F2303;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice specifically addresses the criteria fordetermining the suitability of gravity sewers for secondary usessuch as the installation of optical fiber systems.1.1.1 This practice applies to the process of selecting gravitysewers that are appropriate for accepting an optical fibersystem as opposed to standards for the installation,operationand maintenance of such system within sewers.1.2 This practice applies to both man accessible and maninaccessible sewer systems.1.3 The values stated in inch-pound units are to be regardedas standard.No other units of measurement are included in thisstandard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D543 Practices for Evaluating the Resistance of Plastics toChemical ReagentsD1600 Terminology forAbbreviated Terms Relating to Plas-ticsF412 Terminology Relating to Plastic Piping Systems2.2 Other Documents:NASSCO Standard“Gravity Sanitary Sewer Design andConstruction,”Manual of Practice No.FD-5,ASCE Rec-ommended Specifications for Sewer Collection SystemRehabilitationSewer Rehabilitation Manual(SRM)produced by the WaterResearch Center(WRc,Swindon,England)3.Terminology3.1 Definitions are in accordance with Terminology F412and abbreviations are in accordance with Terminology D1600,unless otherwise specified.3.2 Definitions of Terms Specific to This Standard:3.2.1 combined sewerssewers that carry both wastewaterand storm or surface water.3.2.2 engineerthe licensed professional designated by theowner/operator of the sewer system to represent the owners/operators interests during the selection process.3.2.3 installerthe person(s)or body installing the opticalfiber system within the sewer.3.2.4 manholesvertical shafts to connect intersecting sew-ers to allow transitions in size,alignment and grade and toallow entry to the sewers for cleaning,inspection,and main-tenance.3.2.5 optical fiber cablecable formed of many strands ofoptical fiber for transmission of data,video,audio,voice,andother information.3.2.6 optical fiber conduitfully-supported tubes suitablyaffixed to or suitably incorporated into the wall structure of thesewer.3.2.7 optical fiber systemthe complete set of installedoptical fiber components including cable,conduit and attach-ment components.3.2.8 owner/operatorthe person(s)or body charged withmaintenance and operation of the sewer system.3.2.9 sanitary sewerssewers that carry wastewater fromusers to the treatment plant.3.2.10 service lateralportion of the sewer system thatconnects a user to the sewer.3.2.11 sewerburied piping designed to carry wastewateror storm run-off.3.2.12 storm sewerssewers that carry storm or surfacewater away from roadways or structures to waterways.1This practice is under the jurisdiction of ASTM Committee F36 on Technologyand Underground Utilities and is the direct responsibility of Subcommittee F36.10on Optical Fiber Systems within Existing Infrastructure.Current edition approved June 1,2015.Published June 2015.Originallyapproved in 2003.Last previous edition approved in 2009 as F2303 03(2009).DOI:10.1520/F2303-03R15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 4.Summary of Practice4.1 Optical fiber cable and conduit systems in existingsewers shall be designed and installed so that they have aminimal effect on the sewers hydraulic performance and noeffect on their structural integrity.Their design and installationshall also allow for the safe and efficient operation andmaintenance of the sewer,and provide for the safe and efficientoperation of the optical fiber system.The ultimate success ofthe installation and operation of optical fiber and sewer systemsdepends upon the proper evaluation and selection of appropri-ate sewers.The steps in the process include the followingitems:4.1.1 Cleaning,4.1.2 Inspection and evaluation of the sewers which arecandidates for optical fiber cable or conduit installation,4.1.3 Selection of sewer route,and4.1.4 Documentation of cable r
