Downspout
A downspout, waterspout, downpipe, drain spout, drainpipe, roof drain pipe, rone or leader is a pipe for carrying rainwater from a rain gutter. The purpose of a downspout is to allow water from a gutter to reach the ground without dripping or splashing down the building structure. Downspouts are usually vertical and usually extend down to ground level, although may be routed at an angle to avoid architectural features and may discharge onto an intermediate roof. At the bottom of downspout there are typically features to divert discharged water away from the building's foundations to prevent water damage. This may be a simple bend of, typically around 70 degrees, at the bottom. Alternatively a downspout may lead to a sewer, a runoff water drain or a seepway to allow the water to soak into the ground through seepage. Decorative heads are sometimes added, these being low-height gargoyles. See also * Copper downspout * Rain gutter * Eaves * Leader head * Rain chain * ...

Copper In Architecture
Copper has earned a respected place in the related fields of architecture, building construction, and interior design.Kireta Jr., Andy (2009). The copper advantage, ''Metal Architecture,'' June 2009; www.metalarchitecture.com From cathedrals to castles and from homes to offices, copper is used for a variety of architectural elements, including roofing material, roofs, flashing (weatherproofing), flashings, rain gutter, gutters, downspouts, domes, spires, vault (architecture), vaults, copper cladding, wall cladding, and building expansion joints. The history of copper in architecture can be linked to its durability, corrosion resistance, prestigious appearance, and ability to form complex shapes.Austin, Jim (2006). Copper: The peacock of metals, ''Metal Roofing,'' April–May 2006; www.metalroofingmag.com For centuries, craftsmen and designers utilized these attributes to build aesthetically pleasing and long-lasting building systems.Seale, Wayne (2007).

Leader Head
Leader heads or conductor heads are funnel-shaped components of a roof drainage system connected in most cases to a Rain gutter, gutter and to a downspout. The system conveys water from the roof that is collected in the gutters to the ground or into a storm water management system. Purpose The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles. The use of leader heads also offers other benefits to the drainage system. Because the top of the funnel is open, air is constantly introduced into the system and water flows faster through the downspouts. Additionally, some leader heads are designed to receive more than one downspout, or in some cases more than one gutter converge onto a single leader head. Leader heads have historically provided an opportunity to incorporate a decorative element within t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain Gutter
A rain gutter, eavestrough, eaves-shoot or surface water collection channel is a component of a water discharge system for a building. It is necessary to prevent water dripping or flowing off roofs in an uncontrolled manner for several reasons: to prevent it damaging the walls, drenching persons standing below or entering the building, and to direct the water to a suitable disposal site where it will not damage the foundations of the building. In the case of a flat roof, removal of water is essential to prevent water ingress and to prevent a build-up of excessive weight. Water from a pitched roof flows down into a valley gutter, a parapet gutter or an eaves gutter. An ''eaves gutter'' is also known as an ''eavestrough'' (especially in Canada), ''spouting'' in New Zealand, ''rhone'' or ''rone'' (Scotland), ''eaves-shoot'' (Ireland) ''eaves channel,'' ''dripster'', ''guttering'', ''rainspouting'' or simply as a ''gutter''. The word ''gutter'' derives from Latin ''gutta'' (noun) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rain Chain
Rain chains (, or ', literally "chain-gutter") are alternatives to a downspout. They are widely used in Japan. Their purpose is largely decorative, to make a water feature out of the transport of rainwater from the guttering downwards to a drain or to a storage container. (Rainwater is sometimes collected for household usage.) They can also be found on temples. Rain chains are typically either a series of metal cups, chained together with a hole in the bottom of each, or chain links that span vertically. Rain water run-off gets distributed from a rooftop gutter downward through the rain chain. Rain chains have also been used in the West. Nordic vernacular architecture often used a simple stick as a rainwater guide, in similar fashion. They have also been used in the Modernist era, to juxtapose metal chains with a concrete or Portland stone Portland stone is a limestone geological formation (formally named the Portland Stone Formation) dating to the Tithonian age of the ...

Rainwater Harvesting
Rainwater harvesting (RWH) is the collection and storage of rain, rather than allowing it to run off. Rainwater is collected from a roof-like surface and redirected to a Rainwater tank, tank, cistern, deep pit (well, shaft, or borehole), Aquifer storage and recovery, aquifer, or a reservoir with percolation, so that it seeps down and restores the ground water. Rainwater harvesting differs from stormwater harvesting as the runoff is typically collected from roofs and other area surfaces for storage and subsequent reuse. Its uses include watering gardens, livestock, irrigation, Drinking water, domestic use with proper treatment, and domestic heating. The harvested water can also be used for long-term storage or groundwater recharge. Rainwater harvesting is one of the simplest and oldest methods of Self-supply of water and sanitation, self-supply of water for households, having been used in South Asia and other countries for many thousands of years. Civilizations such as the Romans de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eaves
The eaves are the edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. The eaves form an overhang to throw water clear of the walls and may be highly decorated as part of an architectural style, such as the Chinese dougong bracket systems. Etymology and usage According to the ''Oxford English Dictionary'', ''eaves'' is derived from the Old English (singular), meaning "edge", and consequently forms both the singular and plural of the word. This Old English word is itself of Germanic origin, related to the German dialect ''Obsen'', and also probably to ''over''. The Merriam-Webster dictionary lists the word as ''eave'' but notes that it is "usually used in plural". Function The primary function of the eaves is to keep rain water off the walls and to prevent the ingress of water at the junction where the roof meets the wall. The eaves may also protect a pathway around the building from the rain, prevent erosion of the footi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seepage
In soil mechanics, seepage is the movement of water through soil. If fluid pressures in a soil deposit are uniformly increasing with depth according to u = \rho_w g z_w, where z_w is the depth below the water table, then hydrostatic conditions will prevail and the fluids will be flowing through the soil. However, if the water table is sloping or there is a perched water table as indicated in the accompanying sketch, then seepage will occur. For steady state seepage, the seepage velocities are not varying with time. If the water tables are changing levels with time, or if the soil is in the process of consolidation, then steady state conditions do not apply. Darcy's law Darcy's law states that the volume of flow of the pore fluid through a porous medium per unit time is proportional to the rate of change of excess fluid pressure with distance. The constant of proportionality includes the viscosity of the fluid and the intrinsic permeability of the soil. For the simple case of a ...

Gargoyle
In architecture, and specifically Gothic architecture, a gargoyle () is a carved or formed Grotesque (architecture), grotesque with a spout designed to convey water from a roof and away from the side of a building, thereby preventing it from running down masonry walls and eroding the Mortar (masonry), mortar between. Architects often used multiple gargoyles on a building to divide the flow of rainwater off the roof to minimize potential damage from rainstorms. A trough is cut in the back of the gargoyle and rainwater typically exits through the open mouth. Gargoyles are usually elongated fantastical animals because their length determines how far water is directed from the wall. When Gothic art, Gothic flying buttresses were used, aqueduct (watercourse), aqueducts were sometimes cut into the buttress to divert water over the aisle walls. Etymology The term originates from the French language, French ''gargouille'' (Old French ''gargoule'' (1294) "conduit for waterflow"), com ...

Sewerage
Sewerage (or sewage system) is the infrastructure that conveys sewage or surface runoff ( stormwater, meltwater, rainwater) using sewers. It encompasses components such as receiving drains, manholes, pumping stations, storm overflows, and screening chambers of the combined sewer or sanitary sewer. Sewerage ends at the entry to a sewage treatment plant or at the point of discharge into the environment. It is the system of pipes, chambers, manholes or inspection chamber, etc. that conveys the sewage or storm water. In many cities, sewage (municipal wastewater or municipal sewage) is carried together with stormwater, in a combined sewer system, to a sewage treatment plant. In some urban areas, sewage is carried separately in sanitary sewers and runoff from streets is carried in storm drains. Access to these systems, for maintenance purposes, is typically through a manhole. During high precipitation periods a sewer system may experience a combined sewer overflow event or ...
