A scruffy dome is a steel grille that is placed over the inlet of a manhole, and is usually dome shaped. They function as a way for stormwater to enter the pipe network without allowing larger debris in, such as people or animals. [1] [2] Scruffy domes are usually used in parks and wetlands, and are usually made with galvanised steel. [2]
A spandrel is a roughly triangular space, usually found in pairs, between the top of an arch and a rectangular frame; between the tops of two adjacent arches or one of the four spaces between a circle within a square. They are frequently filled with decorative elements.
A geodesic dome is a hemispherical thin-shell structure (lattice-shell) based on a geodesic polyhedron. The triangular elements of the dome are structurally rigid and distribute the structural stress throughout the structure, making geodesic domes able to withstand very heavy loads for their size.
A dome is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them.
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also carry industrial wastewater. In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters. An advantage of sanitary sewer systems is that they avoid combined sewer overflows. Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff. Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging infrastructure.
A storm drain, storm sewer, surface water drain/sewer, or stormwater drain is infrastructure designed to drain excess rain and ground water from impervious surfaces such as paved streets, car parks, parking lots, footpaths, sidewalks, and roofs. Storm drains vary in design from small residential dry wells to large municipal systems.
A dry well or drywell is an underground structure that disposes of unwanted water, most commonly surface runoff and stormwater, in some cases greywater or water used in a groundwater heat pump. It is a gravity-fed, vertical underground system that can capture surface water from impervious surfaces, then store and gradually infiltrate the water into the groundwater aquifer.
A passenger railroad car or passenger car, also called a passenger carriage, passenger coach, or passenger bogie is a railroad car that is designed to carry passengers. The term passenger car can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars.
A swale is a shady spot, or a sunken or marshy place. In US usage in particular, it is a shallow channel with gently sloping sides. Such a swale may be either natural or human-made. Artificial swales are often infiltration basins, designed to manage water runoff, filter pollutants, and increase rainwater infiltration. Bioswales are swales that involve the inclusion of plants or vegetation in their construction, specifically.
The Charles H. Wright Museum of African American History, or The Wright, is located in Detroit, Michigan in the U.S.; inside the city's Midtown Cultural Center is one of the world's oldest independent African American museums.
"Renegade" is a 1979 hit song recorded by the American rock band Styx on their Pieces of Eight album. Although songwriter Tommy Shaw and fellow Styx guitarist James Young usually played lead guitar on their own compositions, Shaw asked Young if he could take the solo on "Renegade". Young agreed, and Young later returned the favor by allowing Shaw to play lead on his "Half-Penny, Two-Penny" on the Paradise Theatre album. When performed live from 1978 to 1983, drummer John Panozzo increased the tempo of the drum pattern during the guitar solo sections. Also, the track would serve as the drum solo spot for Panozzo during that time frame.
The Sinan Erdem Dome, formerly known as the Ataköy Dome, is a multi-purpose indoor arena that is located in Ataköy, Bakırköy, Istanbul on the European side of Istanbul, Turkey.
The Sydney SuperDome is a large multipurpose arena located in Sydney Olympic Park suburb of Sydney, New South Wales, Australia. It was completed in 1999 as part of the facilities for the 2000 Summer Olympics.
An air-supportedstructure is any building that derives its structural integrity from the use of internal pressurized air to inflate a pliable material envelope, so that air is the main support of the structure, and where access is via airlocks.
Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and maneuvered into place; examples include precast beams, and wall panels for tilt up construction. In contrast, cast-in-place concrete is poured into site-specific forms and cured on site.
A stormwater detention vault is an underground structure designed to manage excess stormwater runoff on a developed site, often in an urban setting. This type of best management practice may be selected when there is insufficient space on the site to infiltrate the runoff or build a surface facility such as a detention basin or retention basin.
A percolation trench, also called an infiltration trench, is a type of best management practice (BMP) that is used to manage stormwater runoff, prevent flooding and downstream erosion, and improve water quality in an adjacent river, stream, lake or bay. It is a shallow excavated trench filled with gravel or crushed stone that is designed to infiltrate stormwater though permeable soils into the groundwater aquifer.
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces are constructed during land development. During rain, storms, and other precipitation events, these surfaces, along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table and flooding since the amount of water that remains on the surface is greater. Most municipal storm sewer systems discharge untreated stormwater to streams, rivers, and bays. This excess water can also make its way into people's properties through basement backups and seepage through building wall and floors.
A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. Check dams themselves are not a type of new technology; rather, they are an ancient technique dating from the second century AD. Check dams are typically, though not always, implemented in a system of several dams situated at regular intervals across the area of interest.
Water-sensitive urban design (WSUD) is a land planning and engineering design approach which integrates the urban water cycle, including stormwater, groundwater, and wastewater management and water supply, into urban design to minimise environmental degradation and improve aesthetic and recreational appeal. WSUD is a term used in the Middle East and Australia and is similar to low-impact development (LID), a term used in the United States; and Sustainable Drainage System (SuDS), a term used in the United Kingdom.
Lewisham Sewage Aqueduct is a heritage-listed sewage aqueduct in Gadigal Reserve, adjacent to 5 Grosvenor Crescent, Summer Hill, Inner West Council, Sydney, New South Wales, Australia. It was designed by Sewerage Construction Branch and Department of Public Works and built in 1900. The property is owned by Sydney Water. It was added to the New South Wales State Heritage Register on 18 November 1999.
