5.1 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 or storm water, or both. 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.
5.2 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.
5.3 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.View Less
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 standard. No other units of measurement are included in this standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
