Standard Practice for Selection of Gravity Sewers Suitable for Installation of Optical Fiber Cable and Conduits

Significance and Use

This practice is intended to assist engineers and sewer owner/operators in determining the suitability of sewers for a secondary use as hosts for optical fiber cables and conduits. It must be kept in mind that the primary use of the sewers is to carry wastewater and/or storm water. Any secondary use of the system shall not significantly impair the primary use. It is up to the engineer to decide upon any exceptions that may be involved in the selection process.

Before the selection procedure begins, the installer must have explicit authorization from the owner/operator allowing an evaluation to be conducted for the installation of optical fiber cables or conduits within their sewer system.

Engineers and owners should also be cognizant of how the installation of optical fiber cable or conduits will impact the future operational, maintenance and rehabilitation needs of the sewers.


1.1 This practice specifically addresses the criteria for determining the suitability of gravity sewers for secondary uses such as the installation of optical fiber systems.

1.1.1 This practice applies to the process of selecting gravity sewers that are appropriate for accepting an optical fiber system as opposed to standards for the installation, operation and maintenance of such system within sewers.

1.2 This practice applies to both man accessible and man inaccessible sewer systems.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values provided in parentheses are for information purposes only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
