Optical fibre cables - Sewer cables - Family specification for cables to be installed in storm and sanitary sewers

This document is a family specification that covers sewer cables and conduits for installation by blowing and/ or pulling in non-man accessible storm and sanitary sewers, also applicable for man-accessible and lateral ones. Systems built with components covered by this standard are subject to the requirements of sectional specifications EN 60794-3 and EN 60794-4 where applicable. Sewer cable and conduit constructions have to meet the different requirements of the sewer operating companies and / or associations regarding chemical, environmental, operational, cleaning and in general maintenance conditions. A table of preferential applications, describing sewer cable characteristics versus methods of installation is reported in Annex A for non-man accessible sewers. Clause 4 describes a blank detail specification for sewer cables and conduits for installation by blowing and/or pulling in storm and sanitary sewers. It incorporates some minimum requirements. Detail specifications may be prepared on the basis of this family specification. The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria should be interpreted with respect to this consideration. The number of fibres tested is representative of the sewer cable and should be agreed between the customer and supplier.

Overview

CLC/TS 50429:2005 - Optical fibre cables - Sewer cables is a CENELEC family technical specification that defines requirements for optical fibre sewer cables and conduits intended for installation by blowing and/or pulling in storm and sanitary sewers. It covers non-man-accessible sewers (and is also applicable to man‑accessible and lateral sewers), provides a blank detail specification (Clause 4) with minimum requirements, and includes guidance on preferred applications (Annex A).

Key SEO phrases: CLC/TS 50429:2005, optical fibre cables, sewer cables, storm and sanitary sewers, installation by blowing, installation by pulling.

Key topics and technical requirements

• Design life: Components shall be designed for an expected operating lifetime of at least 15 years and remain installable/removable throughout that lifetime.
• Installation methods: Installation by blowing/pulling into conduits, and direct sewer installation methods such as:
  • drilling and screwing to the inner sewer wall,
  • spanning between manholes (similar to aerial cables),
  • laying on the sewer floor.
• Conduit requirements: Nominal outer diameters 10–16 mm, circular (corrugated if required), low-friction inner surface, able to withstand pressure differences during blowing, chemically resistant (examples include stainless steel VA4). Inner/outer diameters and wall thickness must be specified.
• Cable construction: Options for filled/unfilled tubes, inner/outer sheaths, metallic or non‑metallic armouring, and marking/identification. Individual fibres must be identifiable along cable length. Splicing in a delivery length is not allowed unless agreed.
• Mechanical & environmental testing: Family test requirements for tensile performance, repeated bending, torsion, bend, crush, impact, temperature cycling, and blowing performance. Acceptance criteria should consider measurement uncertainty from test/calibration limitations.
• Rodent protection: Generally required; metallic layers at conduit/cable level are recognized as effective (other non‑metallic solutions under consideration).
• Testing scope: The number of fibres to be tested must be representative and agreed between customer and supplier.

Practical applications

• Installing fiber-optic communications in urban and municipal sewer infrastructure where traditional civil works are impractical or costly.
• Retrofit or new-build telecom links using sewer networks for broadband backhaul, sensor networks, or smart-city connectivity.
• Use cases include non-man-accessible storm/sanitary sewers and man-accessible laterals where space/cleaning/chemical exposure impose special requirements.

Who should use this standard

• Cable manufacturers and conduit suppliers designing sewer-rated optical fibre products.
• Network planners, system integrators, and telecom contractors specifying installation methods and procurement requirements.
• Sewer operating companies and maintenance teams setting operational, cleaning, chemical and rodent-protection specifications.
• Spec writers and procurement engineers preparing detail specifications based on the blank specification in Clause 4.

Related standards

• EN 60794-1-1, EN 60794-1-2 (generic cable specs and test procedures)
• EN 60794-3, EN 60794-4 (sectional specifications for outdoor and aerial cables)
• Other referenced EN/IEC test methods listed in Clause 2 of CLC/TS 50429:2005

This specification is a practical reference for safe, durable optical fibre deployment in sewer environments, aligning cable design, testing and installation practices with operational constraints.

4 Family specification for sewer cables and conduits for installation by
blowing and/or pulling in sewers (blank detail specification and minimum
requirements)
4.1 Construction
4.1.1 General
In addition to the constructional requirements of sectional specifications EN 60794-3 and
EN 60794-4, where applicable, the following considerations apply to the sewer cables and/or
conduits.
The sewer cables and/or conduits shall be designed and manufactured for an expected
operating lifetime of at least 15 years. It shall be possible to install or remove the cable in or
from the sewer throughout the operational lifetime. The materials in the sewer cable and / or as
well as accessories including fixing elements and conduits shall not present a health hazard
within its intended use.
4.1.2 Conduits
In case of use, the conduits with outer nominal diameters ranging from 10 mm to 16 mm shall
be able to resist pressure differences needed for installation by blowing. They shall be circular
and, if needed, corrugated in cross-section throughout their length; the inner surface shall have
a low coefficient of friction. The material shall withstand all possible chemical attacks by the
sewer liquid itself, as for instance the stainless steel type VA4. Inner- and outer-diameter and
overall minimum wall thickness shall be specified.
4.1.3 Sewer cables
A sewer cable in accordance to this specification should be suitable for installation in non-man
accessible storm and sanitary sewers by the following installation methods, also applicable for
man-accessible sewers and for lateral sewer systems:
∇
∇
∇ blowing and /or pulling into a conduit, previously fixed to the sewer wall or, for laterals,
placed in between the lateral sewer wall and the in-liner system;
∇
∇
∇ direct installation into the sewer duct, according to the following applications:
o drilling and screwing to the inner wall;
o spanning between manholes, etc., similarly to aerial cables;
o laying on the ground of the sewer.
The attenuation of the installed cable at the operational wavelength(s) shall not exceed values
agreed between the customer and supplier.
There shall be no fibre splice in a delivery length unless otherwise agreed by the customer and
supplier.
It shall be possible to identify each individual fibre throughout the length of the sewer cable.

4.1.4 Rodent protection
Rodent protection is generally needed but there is presently no standard test to measure the
level of rodent protection.
It is recognized that an effective protection is provided by a metallic layer at level of conduit or
cable. Other solutions using non metallic elements, for example rigid glass members or glass
tapes are under consideration.

designed robot, or spanned – similar to aerial cables – by means of anchors between two man-
holes limiting sag and interference with lateral tubes, or laid and fixed on the ground of the
sewer mainly by gravity and a certain number of anchor devices.
