Underground Pneumatic Waste
Nowadays, some cities are adopting underground pneumatic waste systems to transport and collect garbage without any surface activity.Read more

Another essential use of the underground space in urban environments is the distribution of electrical and communication cables.Read more
With large concentrations of people in limited space, it has become necessary to utilize the subsurface for locating a growing number of services in urban environments:
- Water supply, waste water disposal and drainage of rainwater are since ancient times prevailing activities in the underground space of the main cities.
- Complex and efficient systems to regulate urban utilities and fight against challenges like floods and pollution in the urban environment.
- The development of gas in the cities also led to a need of underground use. For safety reasons, gas ducts that were before left in the open air started to be put underground, reducing the gravity and risk of explosions.
- New underground conductions being developed to cater for new services, like it is the case of pneumatic waste ducts, IT communications, etc.
These installations are designed to conform to the basic pattern of the overhead surface plan.
As an area increases in density, this space becomes cluttered with supply lines. One way to accommodate the growing demand for conduits is to place them in somewhat deeper tunnels freed from the general plan of the surface.
Excavated in soft ground or rock, these utility tunnels are not bound to the surface design. Because such tunnels are generally situated deeper than trench pipes, they are able to avoid the aged near-surface infrastructure during construction.
Therefore, as these supply lines are tunneled rather than dug directly from the surface there is no interruption of surface traffic, causing also less disruption and damage to existing installations.
