Non Urban Utilities

Energy transportation might also need the construction of tunnels, when high voltage electricity cables, oil ducts, gas ducts, etc , are built underground for safety, environmental or functional reasons.

A very good example of facilities where the underground space is used to convey water are underground hydropower stations.

In order to guarantee the supply of water to the always growing urban agglomerations, infrastructures must be built to convey this liquid resource, bridging valleys and crossing ranges of mountains.

The disposal of spent nuclear fuel must be organised in a way that is not harmful to organic nature.

In order to fulfil strategic requirements in term of stable supply of energy, many countries need to have large oil and gaz storage capacities.
