1、Designation: F2462 05 (Reapproved 2010)Standard Practice forOperation and Maintenance of Sewers with Optical FiberSystems1This standard is issued under the fixed designation F2462; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, th
2、e 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 applies to the operation and maintenanceof sewers with a subsequent installation of optical fi
3、ber cable inaccordance with Practice F2303.1.2 This practice applies to gravity flow storm sewers,sanitary sewers, and combined sewers.1.3 This practice does not apply to force mains, siphons, orother pressurized sewers.1.4 This standard does not purport to address all of thesafety concerns, if any,
4、 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.

Significance and Use5.1 This is intended to outline O and6.3.2.2 Where assistance by the optical fiber cable ownermay be necessary.6.4 Routine Operating Procedures:6.4.1 Notification:6.4.1.1 The sewer operator and fiber cable system ownershould notify the other entity as far in advance as possi
9、ble forplanned, routine operations.6.4.1.2 Improper cable repair or maintenance proceduresmay damage the sewer or optical fiber system, creating anunsafe situation. Because of this risk, the fiber cable systemowner must notify the sewer pipeline operator as to the natureof the intended repair or mai
10、ntenance and verify whether seweroperator supervision or oversight is required during the repairor maintenance.6.4.2 Extended Duration Access (4 hours+) to Sewer Vaultsby Optical Fiber System OwnerWhen accessing a sewervault or sewer manhole, the optical fiber cable owner mustprovide the sewer pipel
11、ine operator with at least 48 hours priornotice. If re-cabling, replacing the conduit or other extendeddurations repairs are contemplated, the optical fiber systemowner must provide with that notice, written repair procedures,the duration and hours that the vault or manhole is beingaccessed and othe
12、r requirements which may be locally required(traffic control plans, odor control, and so forth).6.4.3 Sewer Service ConnectionsThe optical fiber cableowner must provide the sewer pipeline operator with preferredmethods for adding sewer service connections. In the absenceof those preferences, the sew
13、er pipeline operator may use anycustomary method.6.4.4 Sewer Pipeline Maintenance and RehabilitationTheoptical fiber cable owner must provide the sewer pipelineoperator with preferred methods for chemicals used for odor,grease or root control, mechanical cleaning methods forblockages or roots, hydra
14、ulic cleaning or flushing methods,pipeline and manhole rehabilitation techniques, and so forth. Inthe absence of those preferences, the sewer pipeline operatormay use any customary method.F2462 05 (2010)26.5 Mutual Advice:6.5.1 During any inspection, the sewer pipeline operator oroptical fiber cable
15、 owner should advise the other of anydamage observed in the others facilities. Items that requireattention by the sewer pipeline operator include infiltration,flooded manholes, root intrusions, and so forth. Items thatrequire attention of the optical fiber cable owner include vaultlid damage, crimps
16、, open splice cases, standing water, pinches,nicks, or cuts in cable jacketing.6.6 Marking and Identification:6.6.1 VaultsIn sewer reaches containing optical fibercables, each sewer access (vault) must be clearly and conspicu-ously identified as containing optical fiber cables. A contactnumber must
17、be provided where the optical fiber cable owneror sewer pipeline operator may access further instructions onhow to safely proceed.6.6.2 ConduitConduit containing optical fiber cable (lo-cated outside of the pipeline) must be clearly and uniquelymarked to minimize the chances that the pipeline operat
