A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics , cable television , and telephone cables are also sometimes carried.
Directional boring, also referred to as horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a relatively shallow arc or radius along a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant ...
Single-home systems can be "vertical loop field" systems with bore holes 50–400 feet (15–120 m) deep or, [16] if adequate land is available for extensive trenches, a "horizontal loop field" is installed approximately six feet subsurface. As the fluid circulates underground it absorbs heat from the ground and, on its return, the warmed fluid ...
Microtunneling or microtunnelling is a tunnel construction technique used to construct utility tunnels from approximately 0.5–4 m (1 ft 8 in – 13 ft 1 in) in diameter. Because of their small diameter, it is not possible to have an operator driving the tunneling machine, so they have to be remotely operated.
Underground pneumatic drills can be used in the installation of public utilities like power lines, gas lines, phone cables, and cable television. It can also be used to install residential lawn irrigation systems. Boring is especially useful when it is difficult or cost-prohibitive to plow or trench.
Cover outside water spigots. Before the temperature drops below 32 degrees, outdoor water spigots attached to homes should be opened to allow to drain water out, closed and then covered.
Utility location is the process of identifying and labeling public utility mains that are underground. These mains may include lines for telecommunication , electricity distribution , natural gas , cable television , fiber optics , traffic lights , street lights , storm drains , water mains , and wastewater pipes.
A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.
