pollutants.
In storage, care must be taken to ensure that the PE-Xa carrier pipe is protected from sunlight and that no undesirable deformation of the coil is occuring.
Pipes must be transported and stored in such a way that sharp objects, like
stones and tree roots cannot damage them. Pipes must not be dragged
along the ground. Only nylon or textile straps should be used for fastening
the coils during transport.

A land register plan might be useful to eliminate possible conflicts with existing or future utilities and structures.
After completion of the pipe-laying process, the route can be marked with a
