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.

1 Scope
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.

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.

4.2.1.2 Cables for direct installation into the sewer duct
Such cables are directly screwed on the sewer wall by means of proper “hooks” using a special
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.

Such conduit is directly attached on the sewer wall by means of proper fittings. In case of use of
stainless-steel-conduits, the conduit is fixed by clamps to spring loaded stainless-steel rings
installed into the cleaned and inspected sewer tube, distanced about 1,5 m, using a special
installation robot.
