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, Kakumäe Kakumäe ( Estonian for ''"Owl Hill"'') is a subdistrict ( et, asum) in the district of Haabersti, 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 components such ...

Drinking Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking 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. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Estonia
Estonia, formally the Republic of Estonia, is a country by the Baltic Sea in Northern Europe. It is bordered to the north by the Gulf of Finland across from Finland, to the west by the sea across from Sweden, to the south by Latvia, and to the east by Lake Peipus and Russia. The territory of Estonia consists of the mainland, the larger islands of Saaremaa and Hiiumaa, and over 2,200 other islands and islets on the eastern coast of the Baltic Sea, covering a total area of . The capital city Tallinn and Tartu are the two largest urban areas of the country. The Estonian language is the autochthonous and the official language of Estonia; it is the first language of the majority of its population, as well as the world's second most spoken Finnic language. The land of what is now modern Estonia has been inhabited by '' Homo sapiens'' since at least 9,000 BC. The medieval indigenous population of Estonia was one of the last " pagan" civilisations in Europe to adopt Ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tallinn
Tallinn () is the most populous and capital city of Estonia. Situated on a bay in north Estonia, on the shore of the Gulf of Finland of the Baltic Sea, Tallinn has a population of 437,811 (as of 2022) and administratively lies in the Harju ''maakond'' (county). Tallinn is the main financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city Tartu, however only south of Helsinki, Finland, also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name Reval. Tallinn received Lübeck city rights in 1248,, however the earliest evidence of human population in the area dates back nearly 5,000 years. The medieval indigenous population of what is now Tallinn and northern Estonia was one of the last " pagan" civilisations in Europe to adopt Christianit ...

Surface Water
Surface water is water located on top of land forming terrestrial (inland) 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 lakes, rivers and wetlands (marshe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Ülemiste
Lake Ülemiste ( et, Ülemiste järv) 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 l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater 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 recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, perma ...
