As a matter of principle, Terre Blanche has systematically favoured, through a long-term vision that is economical in terms of operation, the burial of any structure that does not require an overhead installation, an installation that is unfortunately and all too often dictated by an economic consideration of immediate profitability.
Furthermore, the accessibility of the networks for their adaptation to technical evolutions and to the imperatives of upkeep and maintenance was privileged, thus preserving de facto the landscape installations that buried networks could not sustain.
The impact in terms of waterproofing of the surface is also reduced and thus contributes to a reasoned management of runoff water for which the most permeable surfaces are necessary to reduce instantaneous flows.
