Tallinn Water Supply System
Tallinn water supply system is a water supply system that provides potable water to Estonia's capital city Tallinn. 90% of Tallinn's potable water is produced from the surface water. The heart of the system Ülemiste Water Treatment Plant is located in the centre of the city, beside the Lake Ülemiste. Because the natural catchment of the lake is quite small (52 km²), additional water is directed to Ülemiste via canals from Pirita, Jägala, Soodla and even from the upper stream of the Pärnu River in Pandivere Heights. The system includes 6 water reservoirs and 69 km of canals and pipelines, which makes the total area of the catchment 1865 km². The remaining 10% of the water in Tallinn comes from 29 groundwater wells, mostly in the outskirts ( Nõmme, Pirita Pirita is one of the eight administrative districts () of Tallinn, the capital of Estonia.

Water Supply Network
A water supply network or water supply system is a system of engineered hydrologic and hydraulic components that provide water supply. A water supply system typically includes the following: # A drainage basin (see water purification – sources of drinking water) # A raw water collection point (above or below ground) where the water accumulates, such as a lake, a river, or groundwater from an underground aquifer. Raw water may be transferred using uncovered ground-level aqueducts, covered tunnels, or underground water pipes to water purification facilities. # Water purification facilities. Treated water is transferred using water pipes (usually underground). # Water storage facilities such as reservoirs, water tanks, or water towers. Smaller water systems may store the water in cisterns or pressure vessels. Tall buildings may also need to store water locally in pressure vessels in order for the water to reach the upper floors. # Additional water pressurizing compone ...

Drinking Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Surface Water
Surface water is water located on top of land, forming terrestrial (surrounding by land on all sides) waterbodies, and may also be referred to as ''blue water'', opposed to the seawater and waterbodies like the ocean. The vast majority of surface water is produced by precipitation. As the climate warms in the spring, snowmelt runs off towards nearby streams and rivers contributing towards a large portion of human drinking water. Levels of surface water lessen as a result of evaporation as well as water moving into the ground becoming ground-water. Alongside being used for drinking water, surface water is also used for irrigation, wastewater treatment, livestock, industrial uses, hydropower, and recreation. For USGS water-use reports, surface water is considered freshwater when it contains less than 1,000 milligrams per liter (mg/L) of dissolved solids. There are three major types of surface water. Permanent (perennial) surface waters are present year round, and includes la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Ülemiste
Lake Ülemiste () is the largest of the lakes surrounding Tallinn, Estonia. Ülemiste is the main part of the Tallinn water supply system, which supplies the city with most of its drinking water. The lake is fed mostly by Kurna stream and the Pirita River, through the Vaskjala–Ülemiste canal. Lennart Meri Tallinn Airport is located on the eastern shore of the lake and aircraft regularly take off and land over the lake. The airport maintains the necessary equipment ready to salvage in a short time any aircraft that crashes into the lake, as required by International Civil Aviation Organization regulations. The Tallinn Water Company, AS Tallinna Vesi, has a treatment plant on the north shore of the lake which supplies 90% of the water to the city. The remaining 10% comes from ground water wells, which are maintained as a backup in case the lake becomes contaminated. On 18 March 2010, a DHL Antonov An-26 aircraft made an emergency landing on the ice of the lake, leaking about ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groundwater
Groundwater is the water present beneath Earth's surface in rock and Pore space in soil, soil pore spaces and in the fractures of stratum, rock formations. About 30 percent of all readily available fresh water in the world is groundwater. A unit of rock or an unconsolidated deposit is called an ''aquifer'' when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the ''water table''. Groundwater is Groundwater recharge, recharged from the surface; it may discharge from the surface naturally at spring (hydrosphere), springs and Seep (hydrology), seeps, and can form oasis, oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction water well, wells. The study of the distribution and movement of groundwater is ''hydrogeology'', also called groundwater hydrology. Typically, groundwater is thought o ...
