Water Supply And Sanitation In Spain
Water supply and sanitation in Spain is characterized by universal access and good service quality, while tariffs are among the lowest in the EU. Almost half of the population is served by private or mixed private-public water companies, which operate under concession contracts with municipalities. The largest of the private water companies, with a market share of about 50% of the private concessions, is Aguas de Barcelona ( Agbar). However, the large cities are all served by public companies except Barcelona and Valencia. The largest public company is Canal de Isabel II, which serves the metropolitan area of Madrid. Droughts occasionally affect water supply in Southern Spain, resulting in their consideration of seawater desalination in order to meet water needs. Access Access to water supply and sanitation in Spain is universal. 98% of the urban population and 93% of the rural population is connected to sewers, while the remainder is served by on-site sanitation systems such ...

Polycyclic Aromatic Hydrocarbon
A Polycyclic aromatic hydrocarbon (PAH) is any member of a class of organic compounds that is composed of multiple fused aromatic rings. Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, or when biomass burns at lower temperatures as in forest fires. The simplest representative is naphthalene, having two aromatic rings, and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are also found in fossil fuel deposits such as coal and in petroleum. Exposure to PAHs can lead to different types of cancer, to fetal development complications, and to cardiovascular issues. Polycyclic aromatic hydrocarbons are discussed as possible starting materials for abiotic syntheses of materials required by the earliest forms of life. Nomenclature and structure The terms polyaromatic hydrocarbon, or polynuclear aromatic hydro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basque Country (autonomous Community)
The Basque Country or Basque Autonomous Community (), also officially called Euskadi (), is an Autonomous communities of Spain, autonomous community in northern Spain.

Autonomous Communities Of Spain
The autonomous communities () are the first-level political divisions of Spain, administrative divisions of Spain, created in accordance with the Constitution of Spain, Spanish Constitution of 1978, with the aim of guaranteeing limited autonomy to the nationalities and regions of Spain, nationalities and regions that make up Spain. There are 17 autonomous communities and two autonomous cities (Ceuta and Melilla) that are collectively known as "autonomies". The two autonomous cities have the right to become autonomous communities. The autonomous communities exercise their right to self-government within the limits set forth in the constitution and Organic Law (Spain), organic laws known as Statute of Autonomy, Statutes of Autonomy, which broadly define the powers that they assume. Each statute sets out the devolved powers () for each community; typically those communities with stronger local nationalism have more powers, and this type of devolution has been called ''asymmetric ...

Reclaimed Water
Water reclamation is the process of converting Sewage, municipal wastewater or sewage and Industrial wastewater treatment, industrial wastewater into water that can be reused for a variety of purposes. It is also called wastewater reuse, water reuse or water recycling. There are many types of reuse. It is possible to reuse water in this way in cities or for irrigation in agriculture. Other types of reuse are environmental reuse, industrial reuse, and reuse for drinking water, whether planned or not. Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater. This latter is also known as groundwater recharge. Reused water also serve various needs in residences such as Flush toilet, toilet flushing, businesses, and industry. It is possible to treat wastewater to reach drinking water standards. Injecting reclaimed water into the water supply distribution system is known as direct potable reuse. Drinking reclaimed water is not typical. ...

Non-revenue Water
Non-revenue water (NRW) is water that has been produced and is "lost" before it reaches the customer. Losses can be real losses (through leaks, sometimes also referred to as physical losses) or apparent losses (for example through theft or Water metering, metering inaccuracies). High levels of NRW are detrimental to the financial viability of water utilities, as well to the quality of water itself. NRW is typically measured as the volume of water "lost" as a share of net water produced. However, it is sometimes also expressed as the volume of water "lost" per km of water distribution network per day. Components and audits The International Water Association (IWA) has developed a detailed methodology to assess the various components of NRW. Accordingly, NRW has the following components: * Unbilled authorized consumption * Apparent losses (water theft and metering inaccuracies) * Real losses (from transmission mains, storage facilities, distribution mains or service connections) In ...

Water Desalination
Desalination is a process that removes mineral components from saline water. More generally, desalination is the removal of salts and minerals from a substance. One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. Many seagoing ships and submarines use desalination. Modern interest in desalination mostly focuses on cost-effective provision of fresh water for human use. Along with recycled wastewater, it is one of the few water resources independent of rainfall. Due to its energy consumption, desalinating sea water is generally more costly than fresh water from surface water or groundwater, water recycling and water conservation; however, these alternatives are not always available and depletion of reserves is a critical problem worldwide. Desalination processes are using either thermal methods (i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
