ASTM F2462-05(2015)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

Systems
This standard is issued under the fixed designation F2462; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This practice applies to the operation and maintenance of sewers with a subsequent installation of optical fiber cable in
accordance 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, or other pressurized sewers.

3. Terminology
3.1 Definitions:
3.1.1 conduit, n—tubing used to house optical fiber cable that is connected to, but separate from, a sewer pipeline.
3.1.2 O&M, n—operation and maintenance.
3.1.3 optical fiber cable, n—cable formed of one or more strands of optical fiber for transmission of data, video, audio, voice,
or other information.
3.1.4 optical fiber cable owner, n—entity holding legal rights to, and responsible for the operation and maintenance of, the
optical fiber cable. The optical fiber cable owner is also responsible for operation and maintenance of any components associated
with the optical fiber system that are not part of the sewer pipeline as defined in this standard.
3.1.5 optical fiber system, n—group of components that comprise the elements necessary to enable optical fiber cable to be
installed, maintained, and operated inside a sewer pipeline.
This practice is under the jurisdiction of ASTM Committee F36 on Technology and Underground Utilities and is the direct responsibility of Subcommittee F36.10 on
Optical Fiber Systems within Existing Infrastructure.

3.1.6 sewers, n—pipelines for the conveyance of wastewater or stormwater, or both.
3.1.7 vault, n—manhole, hand hole, or other buried enclosure used to store slack-loops of cable, fiber cable splices or provide
access to the sewer for maintenance and inspection, or any combination thereof. Vaults designated only for optical fiber systems
may be located within the street or off-street. Sewer vaults are typically located in the street and, as approved by the sewer pipeline
operator, may serve the dual purpose of also housing optical fiber systems.
4. Summary of Practice
4.1 Sewers with optical fiber systems must be safely operated and maintained without significant negative impacts on sewer
service and minimal impact on optical fiber system users. To satisfy that criteria, the equipment and practices must be well defined
and designed with responsible workers trained to implement and perform the required tasks. Key issues include:
4.1.1 General safety considerations;
4.1.2 Emergency response procedures, including sewage spill control, emergency sewer pipeline repair, and communication
procedures;
4.1.3 Routine sewer O&M activities, including service and main connections; sewer pipeline repairs; periodic sewer inspection;
sewer pipeline cleaning;
4.1.4 Routine optical fiber system O&M activities;
4.1.5 Cable and conduit marking; and
4.1.6 Worker qualification.
5. Significance and Use
5.1 This is intended to outline O&M issues that require discussion and mutual agreement by both the optical fiber cable owner
and sewer pipeline operator. The purpose is developing sufficient written procedures and practices to allow optical fiber systems
to coexist as a secondary use within a sewer. To the extent that sewers are primarily for conveying flow, it is the responsibility of
the optical fiber cable owner to accommodate sewer O&M practices and develop optical fiber system O&M procedures that will
not material impact the sewer’s primary function.
5.2 Since the practice of integrating sewers and optical fiber systems is an emerging activity, this practice will help establish
guidelines for its rapid and safe deployment, ensuring that the installed facilities are operable as intended on a long-term basis.
6. Operations and Maintenance
6.1 General Safety Considerations:
6.1.1 It may be necessary to continuously monitor air quality for noxious odors and explosive gases in or near sewers.
6.1.2 When working with optical fiber cables, care must be taken to avoid fiber penetration through the skin or laser-induced
eye damage. For specific guidelines, refer to IEC 60825-1, Ed. 1.2, en 2001.
6.1.3 In all instances, only properly trained and certified workers with appropriate skills in optical fiber systems, sewer
maintenance operations, traffic management, traffic safety, confined space, noxious air, flammable gases, hazardous waste disposal,
and so forth, should access or work on sewers or optical fiber systems.
6.1.4 Optical Fiber Fusion Splicing Operations—Fiber fusion splicing equipment may provide a potential ignition source for
flammable mixtures. Prior to fusion splicing, verify the safety of this operation in the presence of potentially flammable sources
(vehicle exhaust, fuel storage, sewers, and so forth).
6.2 Mapping and Record-Keeping:
6.2.1 The optical fiber cable owner must maintain accurate and up-to-date r
