Early uses of waterpower date back to Mesopotamia and ancient Egypt, where irrigation has been used since the 7th millennium BC and water clocks had been used since the early 2nd millennium BC.

Kyrgyzstan uses the entire amount to which the agreement entitles it, but utilization is skewed heavily in favor of agricultural irrigation.

Additionally, irrigation also has a few other uses in crop production, which include protecting plants against frost,

Center pivot irrigation typically uses less water compared to many surface irrigation and furrow irrigation techniques, which reduces the expenditure of and conserves water.

Other common uses for leats include delivery of water for mineral washing and concentration, for irrigation, to serve a dye works or other industrial plant, and provision of drinking water to a farm or household or as a catchment cut-off to improve the yield of a reservoir.

Early uses of water power date back to Mesopotamia and ancient Egypt, where irrigation has been used since the 6th millennium BC and water clocks had been used since the early 2nd millennium BC.

It has been used to provide drinking water, water for livestock, water for irrigation, as well as other typical uses.

Greywater is wastewater generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled on-site for uses such as landscape irrigation and constructed wetlands.

The central feature of the project, the Joe's Valley Reservoir, completed in 1966, for the first time provided long-term water storage, improving the supply for irrigation and making additional water available for industrial uses.

Eventually three canals were built to extend water from the nearby Jordan River to the benchland areas, providing irrigation for agricultural uses to the larger area.

Typical uses ( for other than potable purposes ) include toilet flushing, washing and landscape irrigation.

Greywater, or sullage, is wastewater generated from domestic activities such as laundry, dishwashing, and bathing, which can be recycled on-site for uses such as landscape irrigation and constructed wetlands.

Some municipal sewage systems recycle a certain amount of grey and blackwater using a high standard of treatment, providing reclaimed water for irrigation and other uses.

The lake dried up after its tributary rivers were diverted for agricultural irrigation and municipal water uses.

No overflows occurred after 1878 due to increasing diversions of tributary waters for agricultural irrigation and municipal water uses, and by 1899, the lake was dry except for residual wetlands and occasional floods.

In the San Joaquin Valley, the state and counties built canals to deliver that water and divert the remaining flows for agricultural irrigation and municipal water uses.

Treatment includes irrigation and debridement of necrotic areas ( areas of dead and / or dying gum tissue ), oral hygiene instruction and the uses of mouth rinses and pain medication.

Toxic substances and high populations of certain microorganisms can present a health hazard for non-drinking purposes such as irrigation, swimming, fishing, rafting, boating, and industrial uses.

Yet, water rights run deep in the community's history and water ownership for uses such as irrigation, drinking and industry create unstable flow environments, greatly impacting the abundance of wildlife in and around the river.

The river was used mainly for irrigation of rice fields, but also for drinking water, washing, fishing, and other uses by downstream populations.

A media filter is a type of filter that uses a bed of sand, crushed granite or other material to filter water for drinking, swimming pools, aquaculture, irrigation, stormwater management and other applications.

The sea began to shrink rapidly when sharply increased irrigation and other demands on the only significant tributaries, the Syr Darya and the Amu Darya ( the latter reaching the Aral from neighboring Uzbekistan ), all but eliminated inflow.

Contamination of soil and groundwater with agricultural chemicals, pesticides ; salination, water-logging of soil due to poor irrigation methods ; Caspian Sea pollution ; diversion of a large share of the flow of the Amu Darya into irrigation contributes to that river's inability to replenish the Aral Sea ; desertification

Because water is withdrawn for irrigation, the Amu Darya is navigable only about 250 kilometers downstream from the Afghanistan border to Turkmenabat.

Communal water systems do not meet health standards ; much of the population lacks drinking water systems and must drink water straight from contaminated irrigation ditches, canals, or the Amu Darya itself.

In the early 1970s, the first section of a major irrigation project was completed to divert water from the Amu Darya River in Turkmenistan eastward into Uzbekistan in order to irrigate the land surrounding Qarshi.

The region was probably at its most prosperous in the 1960s and 1970s when irrigation from the Amu Darya was being expanded.

The Amu Darya delta was once heavily populated, and supported extensive irrigation based agriculture for thousands of years.

This drive led to overzealous irrigation withdrawals of irrigation water from the Amu Darya and the subsequent Aral Sea ecological disaster.

In the delta of the River Amu Darya where it reaches the Aral Sea, its waters were channeled for irrigation agriculture by people whose remains resemble those of the nomads of the Andronovo Culture.

In ancient times the river terminated in a delta at the Amu Darya, but has not reached that river since irrigation canals were developed centuries ago.

During the summer, when river flows were greatest, Tajikistan ( located upstream ) released water from its reservoirs on the Vakhsh and exported the hydroelectricity to power irrigation pumps downstream, in Uzbekistan and Turkmenistan, along the Amu Darya.

The streams, and their numerous mountain effluents, not only supply water for irrigation, but also bring down vast quantities of sand, which is deposited alongside their courses, more especially alongside the Syr Darya where it cuts its way through the Khujand-Ajar ridge, forming there the Karakchikum.

The ancient peoples of the Andes such as the Incas have practiced irrigation techniques for over 6, 000 years.

Southern Iraq during Akkadian period seems to have been approaching its modern rainfall level of less than per year, with the result that agriculture was totally dependent upon irrigation.

Even so, the flat country and weather uncertainties made flooding much more unpredictable than in the case of the Nile ; serious deluges seem to have been a regular occurrence, requiring constant maintenance of irrigation ditches and drainage systems.

The two countries have agreed to cooperate in plant science, crops technology, vegetable and fruit preservation, biotechnology, post-harvest technology, livestock, organic agriculture, irrigation and water resources and Halal industry.

Humans have historically used soil as a material for flood control, irrigation purposes, burial sites, building foundations, and as construction material for buildings.

Of the total arable land of 550, 000 hectares, 125, 000 hectares are suited for irrigation, and of those only 75, 000 hectares actually have been improved with irrigation.

Above all, those living or cultivating on the crest of a levee have easy access to water for irrigation and household use in a dry, hot country.

The diversion of water to the Milhat ath Tharthar and the construction of a canal transferring water from the Tigris north of Baghdad to the Diyala River have permitted the irrigation of land outside the limits of the dikes and the expansion of settlement.

Agricultural production expanded until the early 1960s, as additional land was brought under cultivation and some irrigation projects began to have an effect.

: Radioactive or toxic chemical sites associated with its former defense industries and test ranges are found throughout the country and pose health risks for humans and animals ; industrial pollution is severe in some cities ; because the two main rivers which flowed into the Aral Sea have been diverted for irrigation, it is drying up and leaving behind a harmful layer of chemical pesticides and natural salts ; these substances are then picked up by the wind and blown into noxious dust storms ; pollution in the Caspian Sea ; soil pollution from overuse of agricultural chemicals and salination from poor infrastructure and wasteful irrigation practices

" at which point the listeners outline all forms of positive aspects of the Roman occupation such as sanitation, medicine, education, wine, public order, irrigation, roads, a fresh water system, public health and peace, followed by " what have the Romans ever done for us except sanitation, medicine, education ...".

These changes ensured the availability of water for irrigation and made the Murray Valley Australia's most productive agricultural region, but have seriously disrupted the life cycles of many ecosystems both inside and outside the river, and the irrigation has led to dryland salinity that now threatens the agricultural industries.

Alternatively, military vulnerability to invasion from marginal hill tribes or nomadic pastoralists have led to periods of trade collapse and neglect of irrigation systems.

At the same time, Senegal and Mauritania have cooperated successfully with Mali under the Senegal River Development Office ( Organisation pour la Mise en Valeur du Fleuve Sénégal — OMVS ), which was formed in 1972 as a flood control, irrigation, and agricultural development project.

The appearance of the symbol of the seven-headed cobra on SLA propaganda indicates that it was copied from the ancient Sri Lankan / Indian seven-headed nāga ; carved stones depicting a seven-headed cobra are commonly found near the sluices of the ancient irrigation tanks in Sri Lanka and are believed to have been placed there as guardians of the water.

Turkmenistan ’ s irrigation infrastructure and water-use policies have not responded efficiently to this need.

These rivers form the two main river basins of Central Asia ; they are used primarily for irrigation, and several artificial canals have been built to expand the supply of arable land in the Fergana Valley and elsewhere.

The heavy use of agrochemicals, diversion of huge amounts of irrigation water from the two rivers that feed the region, and the chronic lack of water treatment plants are among the factors that have caused health and environmental problems on an enormous scale.

For example, improper cropping and irrigation practices have led to desertification in areas of Uzbekistan, where cotton is a major export.

Diversions, mainly for agricultural irrigation, have increased the natural decrease in flow such that by the time the river reaches Presidio, Texas, there is little or no water.
