When cables and leads need to be laid in the
ground the work is usually performed using
excavation equipment and large lorries. Excavation
takes time and obstructs other traffic in the area ­
sometimes it is necessary to close roads to other
traffic while the excavation work takes place.
Considerate and environmentally friendly
methods are coming in at full speed

When we and our sub-contractors are planning
our work to connect households and companies to
our networks we now increasingly use considerate
and environmentally friendly methods. With micro-
trenching
and sub-channeling cables can be
laid out to customers more quickly and with less
disturbance to nature.

ConstruCtion
methods save
the environment
In brief, micro-trenching means that we cut a
narrow trench in the asphalt. We lay micro pipes in
this cut trench and we can then install micro (fibre)
cables in the micro pipes. Sub-channeling means
that we install "micro sub-pipes" in existing pipes.
This gives us room for more cables in pipes which
would traditionally be regarded as full and we
therefore avoid new excavations.
Telenor's environmental calculator can
calculate the environmental benefit

Telenor has developed an environmental calculator
to calculate the degree to which sub-channeling
and micro-trenching can reduce CO
2
emissions
in relation to standard cable trenching. We saw
the need for such a calculator because the new
methods were unknown in many municipalities,
which were therefore sceptical about giving
permission for the new methods rather than
traditional construction methods. At Telenor
Norway we regard these as environmentally
friendly, effective and safe methods, and the
increased use of micro-trenching and sub-
channeling will have great social value.
Environmentally friendly construction
methods honoured with environmental award
In addition to conducting pioneering activities which
have a substantial effect on our overall environmental
balance Telenor Norway's micro trenching and sub-
channeling experts have been exemplary in their
work to explain and visualise the effects of the new
construction methods. These experts were therefore
pronounced Telenor Norway's internal environmental
heroes in the third quarter of 2012.
