paragraph_text: In a paper published in 1894, it was formally proposed to add chlorine to water to render it ``germ - free ''. Two other authorities endorsed this proposal and published it in many other papers in 1895. Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in Hamburg, Germany, and in 1897 the town of Maidstone, England was the first to have its entire water supply treated with chlorine.

paragraph_text: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 22–27% reduction in disease incidence, and a 21–30% reduction in mortality rate associated with diarrheal disease.

paragraph_text: The Umchabezi River is a tributary of the Mzingwane River in Beitbridge District and Gwanda District, Zimbabwe. The main dam on the river is Makado Dam, which supplies water for commercial irrigation.

paragraph_text: Bisalpur Dam is a gravity dam on the Banas River near Deoli in Tonk district, Rajasthan, India. The dam was completed in 1999 for the purpose of irrigation and water supply.

paragraph_text: Melbourne's air quality is generally good and has improved significantly since the 1980s. Like many urban environments, the city faces significant environmental issues, many of them relating to the city's large urban footprint and urban sprawl and the demand for infrastructure and services. One such issue is water usage, drought and low rainfall. Drought in Victoria, low rainfalls and high temperatures deplete Melbourne water supplies and climate change may have a long-term impact on the water supplies of Melbourne. In response to low water supplies and low rainfall due to drought, the government implemented water restrictions and a range of other options including: water recycling schemes for the city, incentives for household water tanks, greywater systems, water consumption awareness initiatives, and other water saving and reuse initiatives; also, in June 2007, the Bracks Government announced that a $3.1 billion Wonthaggi desalination plant would be built on Victoria's south-east coast, capable of treating 150 billion litres of water per year, as well as a 70 km (43 mi) pipeline from the Goulburn area in Victoria's north to Melbourne and a new water pipeline linking Melbourne and Geelong. Both projects are being conducted under controversial Public-Private Partnerships and a multitude of independent reports have found that neither project is required to supply water to the city and that Sustainable Water Management is the best solution. In the meantime, the drought must be weathered.

paragraph_text: Cyprus suffers from a chronic shortage of water. The country relies heavily on rain to provide household water, but in the past 30 years average yearly precipitation has decreased. Between 2001 and 2004, exceptionally heavy annual rainfall pushed water reserves up, with supply exceeding demand, allowing total storage in the island's reservoirs to rise to an all-time high by the start of 2005. However, since then demand has increased annually – a result of local population growth, foreigners moving to Cyprus and the number of visiting tourists – while supply has fallen as a result of more frequent droughts.

paragraph_text: The Rankine cycle and most practical steam engines have a water pump to recycle or top up the boiler water, so that they may be run continuously. Utility and industrial boilers commonly use multi-stage centrifugal pumps; however, other types are used. Another means of supplying lower-pressure boiler feed water is an injector, which uses a steam jet usually supplied from the boiler. Injectors became popular in the 1850s but are no longer widely used, except in applications such as steam locomotives.

paragraph_text: The Shoalhaven Scheme is a dual-purpose water supply and hydro-electric power generation scheme located on the South Coast region of New South Wales, Australia.

paragraph_text: Water storage and supply for Melbourne is managed by Melbourne Water, which is owned by the Victorian Government. The organisation is also responsible for management of sewerage and the major water catchments in the region as well as the Wonthaggi desalination plant and North–South Pipeline. Water is stored in a series of reservoirs located within and outside the Greater Melbourne area. The largest dam, the Thomson River Dam, located in the Victorian Alps, is capable of holding around 60% of Melbourne's water capacity, while smaller dams such as the Upper Yarra Dam, Yan Yean Reservoir, and the Cardinia Reservoir carry secondary supplies.

paragraph_text: The Ubagan River ( "Obaǵan"; ) is a river of Kazakhstan and Russia, a right tributary of the Tobol River. It has a length of , and a catchment area of , with water supplied by melting snow. In the summer the water is brackish.

paragraph_text: Rivers of the Lahontan watersheds in eastern California are part of the high desert Great Basin and do not drain to the Pacific. Most of the water is used locally in eastern California and western Nevada for irrigation. The Owens River of the South Lahontan region, however, is a principal source of water for Los Angeles.

paragraph_text: In 2019 Los Angeles, former police officer Rick Deckard is detained by officer Gaff, and brought to his former supervisor, Bryant. Deckard, whose job as a "blade runner" was to track down bioengineered beings known as replicants and "retire" (kill) them, is informed that four are on Earth illegally. Deckard starts to leave, but Bryant ambiguously threatens him, and he stays. The two watch a video of a blade runner named Holden administering the "Voigt-Kampff" test, which is designed to distinguish replicants from humans based on their emotional response to questions. The test subject, Leon, shoots Holden on the second question. Bryant wants Deckard to retire Leon and the other three Tyrell Corporation Nexus-6 replicants: Roy Batty, Zhora, and Pris.

paragraph_text: Drinking water supply and sanitation in Egypt is characterised by both achievements and challenges. Among the achievements are an increase of piped water supply between 1990 and 2010 from 89% to 100% in urban areas and from 39% to 93% in rural areas despite rapid population growth, the elimination of open defecation in rural areas during the same period, and in general a relatively high level of investment in infrastructure. Access to an improved water source in Egypt is now practically universal with a rate of 99%. About one half of the population is connected to sanitary sewers.

paragraph_text: The Sudbury Dam Historic District is a historic district on the southeastern end of Sudbury Reservoir off MA 30 in Framingham and Southborough, Massachusetts. The district encompasses the Sudbury Dam (also known as the Fayville Dam for the nearby neighborhood of Southborough), which impounds the reservoir, and an area encompassing several historic structures located below the dam. The area includes water-supply-related structures from three phases of development of the Greater Boston water supply system. It was listed on the National Register of Historic Places in 1990.

Question: Where does the city where Deckard was arrested in Blade Runner, get its water supply?
Answer: Owens River
