Underground Utilities

Basics

• The practice of placing all the various utilities pipes and cables below ground
• This can be:
  • Buried
  • In a Utility tunnel
  • In an above ground "Utility tunnel floor" needs a better name, it's what disneyland orlando does due to florida's water table not allowing for a lower floor

List of Potential Utilities at Neighborhood Level

• Fresh Water (tap water)
• Grey Water Out (if a central recycling system is in use)
• Reclaimed Water In (essentially grey water in) often used for yard irragation while spending less potable water

Gas

• Fuel Gas (most likely compressed methane)
  • Could also be syngas, hydrogen, or a blend

Misc

• Storm Drain
• Steam (if a central plant / chp is available)
