Municipal Infrastructure
Public works are a broad category of infrastructure projects, financed and government procurement, procured by a government body for recreational, employment, and health and safety uses in the greater community. They include public buildings (City and town halls, municipal buildings, schools, and hospitals), transport infrastructure (roads, railroads, bridges, Pipeline transport, pipelines, canals, ports, and airports), public spaces (public squares, parks, and beaches), public services (Water supply network, water supply and Water purification, treatment, sewage treatment, electrical grid, and dams), environmental protection (source water protection, drinking water protection, soil erosion reduction, habitat restoration, wildlife habitat preservation, preservation and restoration of forests and wetlands) and other, usually long-term, physical assets and Building, facilities. Though often interchangeable with public infrastructure and public capital, public works does not necess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Public Square
A town square (or public square, urban square, city square or simply square), also called a plaza or piazza, is an open public space commonly found in the heart of a traditional town or city, and which is used for community gatherings. Related concepts are the civic center, the market square and the village green. Most squares are hardscapes suitable for open market (place), markets, concerts, political rallies, and other events that require firm ground. They are not necessarily a true square, geometric square. Being centrally located, town squares are usually surrounded by small shops such as Bakery, bakeries, meat markets, cheese stores, and clothing stores. At their center is often a well, monument, statue or other feature. Those with fountains are sometimes called fountain squares. The term "town square" (especially via the term "public square") is synonymous with the politics of many cultures, and the names of a certain town squares, such as the Euromaidan or Red Squar ...

Public Capital
Public capital is the aggregate body of government-owned assets that are used as a means for productivity.Aschauer, D. A. (1990). Why is infrastructure important? Conference Series roceedings Federal Reserve Bank of Boston. Pp. 21-68. Such assets span a wide range including: large components such as highways, airports, roads, transit systems, and railways; local, municipal components such as public education, public hospitals, police and fire protection, prisons, and courts; and critical components including water and sewer systems, public electric and gas utilities, and telecommunications.Tatam, J. A. (1993). The Spurious Effect of Public Capital Formation on Private Sector Productivity. Policy Studies Journal, Vol. 21. Often, public capital is defined as government outlay, in terms of money, and as physical stock, in terms of infrastructure. Current state in the U.S. In 1988, the U.S. infrastructure system including all public and private non-residential capital stock was ...

Public Infrastructure
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, airports, public transit systems, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international community h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Building
A building or edifice is an enclosed Structure#Load-bearing, structure with a roof, walls and window, windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the :Human habitats, human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much architecture, artistic expression. ...

Asset
In financial accounting, an asset is any resource owned or controlled by a business or an economic entity. It is anything (tangible or intangible) that can be used to produce positive economic value. Assets represent value of ownership that can be converted into cash (although cash itself is also considered an asset). The balance sheet of a firm records the monetaryThere are different methods of assessing the monetary value of the assets recorded on the Balance Sheet. In some cases, the ''Historical Cost'' is used; such that the value of the asset when it was bought in the past is used as the monetary value. In other instances, the present fair market value of the asset is used to determine the value shown on the balance sheet. value of the assets owned by that firm. It covers money and other valuables belonging to an individual or to a business. ''Total assets'' can also be called the ''balance sheet total''. Assets can be grouped into two major classes: Tangible property, tangib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Restoration
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, destroyed or transformed. It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures. Ecological restoration can help to reverse biodiversity loss, combat climate change, support the provision of ecosystem services and support local economies. The United Nations has named 2021–2030 the Decade on Ecosystem Restoration. Habitat restoration involves the deliberate rehabilitation of a specific area to reestablish a functional ecosystem. This may differ from historical baselines (the ecosystem's original condition at a particular point in time). To achieve successful habitat restoration, it is essential to understand the life cycles and interactions of species, as well as the essential elements such as food, water, nutrients, space, and shelter needed to supp ...

Source Water Protection
Source water protection is a planning process conducted by local water utilities, as well as regional or national government agencies, to protect drinking water sources from overuse and contamination. The process includes identification of water sources, assessment of known and potential threats of contamination, notification of the public, and steps to eliminate the contamination. The process is applicable to lakes, rivers and groundwater (aquifers). Canada Source water protection is part of a multi-barrier approach to protecting municipal sources of drinking water that was recommended by the Canadian Justice Dennis O'Connor in his Walkerton reports. This study was released in 2002 as a response to the Walkerton Tragedy, in which the town of Walkerton, Ontario's drinking water became contaminated with '' E. coli'' bacteria. United States The Safe Drinking Water Act requires each state to delineate the boundaries of areas that public water systems use for their sources of drin ...

Environmental Protection
Environmental protection, or environment protection, refers to the taking of measures to protecting the natural environment, prevent pollution and maintain ecological balance. Action may be taken by individuals, advocacy groups and governments. Objectives include the conservation of the existing natural environment and natural resources and, when possible, repair of damage and reversal of harmful trends. Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the multiple environmental problems. There is disagreement on the extent of the environmental impact of human activity, so protection measures are occasionally debated. Approaches Voluntary agreements In industrial countries, voluntary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Grid
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations, electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers. In that last step, voltage is stepped down again to the required service voltage. Power stations are typically built close to energy sources and far from densely populated areas. Electrical grids vary in size and can cover whole countries or continents. From small to large there are microgrids, wide area synchronous grids, and super grids. The combined transmission and distribution network is part of electricity delivery, known as the ''power grid''. Grids are nearly always synchronous, meaning all distribution areas operate with three phase alternating current (AC) frequencies synchronized (so that voltage swings occur at almost the same ...

Sewage Treatment
Sewage treatment is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated Industrial wastewater treatment, industrial wastewater. There are a large number of sewage treatment processes to choose from. These can range from Decentralized wastewater system, decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incorpo ...

Water Purification
Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water that is fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The history of water purification includes a wide variety of methods. The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination; and the use of electromagnetic radiation such as ultraviolet light. Water purification can reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduce the concentration ...
