Irrigation (also referred to as watering of plants ) is the practice of applying controlled amounts of water to land to help grow crops , landscape plants , and lawns . Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost , suppress weed growth in grain fields, and prevent soil consolidation . It is also used to cool livestock , reduce dust , dispose of sewage , and support mining operations. Drainage , which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation.

84-597: The Kaleshwaram Lift Irrigation Project ( KLIP ) is a multi-purpose irrigation project on the Godavari River in Kaleshwaram , Bhupalpally , Telangana , India . Currently the world's largest multi-stage lift irrigation project, its farthest upstream influence is at the confluence of the Pranahita and Godavari rivers. The Pranahita River is itself a confluence of various smaller tributaries including

168-540: A ball drive, gear drive, or impact mechanism. Rotors can be designed to rotate in a full or partial circle. Guns are similar to rotors, except that they generally operate at very high pressures of 275 to 900 kPa (40 to 130 psi) and flows of 3 to 76 L/s (50 to 1200 US gal/min), usually with nozzle diameters in the range of 10 to 50 mm (0.5 to 1.9 in). Guns are used not only for irrigation, but also for industrial applications such as dust suppression and logging . Sprinklers can also be mounted on moving platforms connected to

252-419: A circular or semi-circular pattern. Traveling Sprinklers: These move along the hose path on their own, watering as they go, ideal for covering long, narrow spaces. Each type offers different advantages based on garden size and shape, water pressure, and specific watering needs. Subirrigation has been used for many years in field crops in areas with high water tables . It is a method of artificially raising

336-589: A clock or timer. Most automatic systems employ electric solenoid valves . Each zone has one or more of these valves that are wired to the controller. When the controller sends power to the valve, the valve opens, allowing water to flow to the sprinklers in that zone. There are two main types of sprinklers used in lawn irrigation, pop-up spray heads and rotors. Spray heads have a fixed spray pattern, while rotors have one or more streams that rotate. Spray heads are used to cover smaller areas, while rotors are used for larger areas. Golf course rotors are sometimes so large that

420-426: A computerized set of valves . In sprinkler or overhead irrigation, water is piped to one or more central locations within the field and distributed by overhead high-pressure sprinklers or guns. A system using sprinklers, sprays, or guns mounted overhead on permanently installed risers is often referred to as a solid-set irrigation system. Higher pressure sprinklers that rotate are called rotors and are driven by

504-494: A direct financial cost to the farmer. Irrigation often requires pumping energy (either electricity or fossil fuel) to deliver water to the field or supply the correct operating pressure. Hence increased efficiency will reduce both the water cost and energy cost per unit of agricultural production. A reduction of water use on one field may mean that the farmer is able to irrigate a larger area of land, increasing total agricultural production. Low efficiency usually means that excess water

588-416: A flood (spate), water is diverted to normally dry river beds (wadis) using a network of dams, gates and channels and spread over large areas. The moisture stored in the soil will be used thereafter to grow crops. Spate irrigation areas are in particular located in semi-arid or arid, mountainous regions. Micro-irrigation , sometimes called localized irrigation , low volume irrigation , or trickle irrigation

672-409: A higher profit than potatoes. The land is flood irrigated twice a day to simulate tidal flooding; the water is pumped from the sea using wind power. Additional benefits are soil remediation and carbon sequestration . Until the 1960s, there were fewer than half the number of people on the planet as of 2024. People were not as wealthy as today, consumed fewer calories and ate less meat , so less water

756-424: A rectangular or square pattern. They are good for covering large, flat areas evenly. Impact (or Pulsating) Sprinklers: These create a rotating, pulsating spray, which can cover a circular or semi-circular area. They are useful for watering large lawns. Stationary Sprinklers: These have a fixed spray pattern and are best for smaller areas or gardens. Rotary Sprinklers: These use spinning arms to distribute water in

840-708: A result of irrigation and the subsequent effects on natural and social conditions in river basins and downstream of an irrigation scheme . The effects stem from the altered hydrological conditions caused by the installation and operation of the irrigation scheme. Amongst some of these problems is depletion of underground aquifers through overdrafting . Soil can be over-irrigated due to poor distribution uniformity or management wastes water, chemicals, and may lead to water pollution . Over-irrigation can cause deep drainage from rising water tables that can lead to problems of irrigation salinity requiring watertable control by some form of subsurface land drainage . In 2000,

924-424: A single sprinkler is combined with a valve and called a 'valve in head'. When used in a turf area, the sprinklers are installed with the top of the head flush with the ground surface. When the system is pressurized, the head will pop up out of the ground and water the desired area until the valve closes and shuts off that zone. Once there is no more pressure in the lateral line, the sprinkler head will retract back into

1008-711: A small discharge to each plant. Micro-irrigation uses less pressure and water flow than sprinkler irrigation. Drip irrigation delivers water directly to the root zone of plants. Subirrigation has been used in field crops in areas with high water tables for many years. It involves artificially raising the water table to moisten the soil below the root zone of plants. Irrigation water can come from groundwater (extracted from springs or by using wells ), from surface water (withdrawn from rivers , lakes or reservoirs ) or from non-conventional sources like treated wastewater , desalinated water , drainage water , or fog collection . Irrigation can be supplementary to rainfall , which

1092-399: Is supplementary to rainfall as happens in many parts of the world, or whether it is ' full irrigation' whereby crops rarely depend on any contribution from rainfall. Full irrigation is less common and only happens in arid landscapes experiencing very low rainfall or when crops are grown in semi-arid areas outside of any rainy seasons. Surface irrigation, also known as gravity irrigation, is

1176-492: Is 58 thousand million cubic feet (tmc) at 75% dependability (i.e. sufficient water is available in 3 out of 4 years) under Godavari Water Disputes Tribunal (GWDT). However the water dependability has reduced to 33% (i.e. sufficient water is available only once in 3 years) in last decade due to more water utilization by Maharashtra and Karnataka by developing excessive water use potential beyond their water use entitlements given by GWDT. Karnataka has constructed four barrages across

1260-486: Is Rs. 46,364 cr. The annual electricity costs are estimated to be Rs. 10,374 cr. Despite the negative report by CAG on the financial viability, the state govt. has made no effort refute the report. Indian Public sector Enterprise BHEL is executing this project and has already commissioned 16 pumping units. In October 2020, the National Green Tribunal , India's court for environmental issues, directed

1344-480: Is a form of sprinkler irrigation utilising several segments of pipe (usually galvanized steel or aluminium) joined and supported by trusses , mounted on wheeled towers with sprinklers positioned along its length. The system moves in a circular pattern and is fed with water from the pivot point at the center of the arc. These systems are found and used in all parts of the world and allow irrigation of all types of terrain. Newer systems have drop sprinkler heads as shown in

1428-503: Is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip irrigation use individual emitters, subsurface drip irrigation (SDI), micro-spray or micro-sprinklers, and mini-bubbler irrigation all belong to this category of irrigation methods. Drip irrigation, also known as microirrigation or trickle irrigation, functions as its name suggests. In this system, water

1512-435: Is about Rs. 5760 crores per year. This implies an additional charge of Rs. 38,400 per acre per year towards the loan repayment. Therefore, the total cost of irrigation per acre is approximately Rs. 85,000 per acre per year. On the other hand, the net profit from the cultivation of the main crop i.e., paddy, could be expected to be around Rs.40,000 per acre per year, assuming two crops in a year. These numbers raise questions about

1596-867: Is also being proposed in the outskirts of Hyderabad of 20–30 TMC to store water. The water will be supplied to this balancing reservoir in the same link. Link-V: From Anicut to Chityala From Anicut, a series of gravity canals and a small tunnel of 1.2 km are planned to transfer water to Gandamalla Reservoir and Baswapuram Reservoir. Thereafter, gravity canals are planned towards Chityal Mandal and its villages. Link-VI: From Sri Komaravelli Mallanna Sagar to Singur Dam From Sri Komaravelli Mallanna Sagar, another sequence of gravity canals, tunnels and lifts are used to transfer water to Singur Dam. Apart from that, if need be, water can be transferred to Nizam Sagar Project and from there, to SRSP. Link-VII: From SRSP Foreshore to Nizam Sagar Canals and to Dilwarpur and Hangarga village for Nirmal and Mudhole Constituency From

1680-415: Is also the means of delivery of fertilizer. The process is known as fertigation . Deep percolation, where water moves below the root zone, can occur if a drip system is operated for too long or if the delivery rate is too high. Drip irrigation methods range from very high-tech and computerized to low-tech and labor-intensive. Lower water pressures are usually needed than for most other types of systems, with

1764-437: Is becoming unsafe for irrigation use and human & cattle consumption. The ground water is also turning into high salinity & alkalinity water. Recently, the water scarcity problem of Pochampadu irrigation system is some extent resolved by supreme court but acute water scarcity faced by Nizam sagar irrigation project is not yet addressed. Supreme court verdict (section 83 ii b) on Babli Project dispute stipulated that

1848-422: Is common in many parts of the world as rainfed agriculture , or it can be full irrigation, where crops rarely rely on any contribution from rainfall. Full irrigation is less common and only occurs in arid landscapes with very low rainfall or when crops are grown in semi-arid areas outside of rainy seasons. The environmental effects of irrigation relate to the changes in quantity and quality of soil and water as

1932-422: Is delivered at or near the root zone of plants, one drop at a time. This method can be the most water-efficient method of irrigation, if managed properly; evaporation and runoff are minimized. The field water efficiency of drip irrigation is typically in the range of 80 to 90% when managed correctly. In modern agriculture, drip irrigation is often combined with plastic mulch , further reducing evaporation, and

2016-457: Is dependent upon farmers having sufficient access to water. However, water scarcity is already a critical constraint to farming in many parts of the world. There are several methods of irrigation. They vary in how the water is supplied to the plants. The goal is to apply the water to the plants as uniformly as possible, so that each plant has the amount of water it needs, neither too much nor too little. Irrigation can also be understood whether it

2100-517: Is divided into 7 links and 28 packages spanning a distance of approximately 500  km (310  mi ) through 13 districts and utilizing a canal network of more than 1,800 km (1,100 mi). The project aims to produce a total of 240 TMC (195 from Medigadda Barrage , 20 from Sripada Yellampalli project and 25 from groundwater ), of which 169 has been allocated for irrigation, 30 for Hyderabad municipal water , 16 for miscellaneous industrial uses and 10 for drinking water in nearby villages, with

2184-424: Is less expensive to install than a center pivot, but much more labor-intensive to operate – it does not travel automatically across the field: it applies water in a stationary strip, must be drained, and then rolled to a new strip. Most systems use 100 or 130 mm (4 or 5 inch) diameter aluminum pipe. The pipe doubles both as water transport and as an axle for rotating all the wheels. A drive system (often found near

2268-518: Is lost through seepage or runoff, both of which can result in loss of crop nutrients or pesticides with potential adverse impacts on the surrounding environment. Nizam Sagar Nizam Sagar Dam is an Indian dam named after the Nizam of Hyderabad. It is a reservoir constructed across the Manjira River , a tributary of the Godavari River , between Achampet and BanjePally villages of

2352-421: Is often no alternative for farmers but to use water polluted with urban waste directly to water their crops. There can be significant health hazards related to using untreated wastewater in agriculture. Municipal wastewater can contain a mixture of chemical and biological pollutants. In low-income countries, there are often high levels of pathogens from excreta. In emerging nations , where industrial development

2436-443: Is often the irrigation choice for developing nations, for low value crops and for large fields. Where water levels from the irrigation source permit, the levels are controlled by dikes ( levees ), usually plugged by soil. This is often seen in terraced rice fields (rice paddies), where the method is used to flood or control the level of water in each distinct field. In some cases, the water is pumped, or lifted by human or animal power to

2520-422: Is outpacing environmental regulation, there are increasing risks from inorganic and organic chemicals. The World Health Organization developed guidelines for safe use of wastewater in 2006, advocating a ‘multiple-barrier' approach wastewater use, for example by encouraging farmers to adopt various risk-reducing behaviors. These include ceasing irrigation a few days before harvesting to allow pathogens to die off in

2604-586: Is practiced in the vineyards at Lanzarote using stones to condense water. Fog collectors are also made of canvas or foil sheets. Using condensate from air conditioning units as a water source is also becoming more popular in large urban areas. As of November 2019 a Glasgow-based startup has helped a farmer in Scotland to establish edible saltmarsh crops irrigated with sea water. An acre of previously marginal land has been put under cultivation to grow samphire , sea blite , and sea aster ; these plants yield

2688-478: Is similar in principle and action to subsurface basin irrigation. Another type of subirrigation is the self-watering container, also known as a sub-irrigated planter . This consists of a planter suspended over a reservoir with some type of wicking material such as a polyester rope. The water is drawn up the wick through capillary action. A similar technique is the wicking bed ; this too uses capillary action. Modern irrigation methods are efficient enough to supply

2772-437: Is supplied at one end using a large hose. After sufficient irrigation has been applied to one strip of the field, the hose is removed, the water drained from the system, and the assembly rolled either by hand or with a purpose-built mechanism, so that the sprinklers are moved to a different position across the field. The hose is reconnected. The process is repeated in a pattern until the whole field has been irrigated. This system

2856-419: Is supplied to plants. Surface irrigation , also known as gravity irrigation, is the oldest form of irrigation and has been in use for thousands of years. In sprinkler irrigation , water is piped to one or more central locations within the field and distributed by overhead high-pressure water devices. Micro-irrigation is a system that distributes water under low pressure through a piped network and applies it as

2940-523: Is the second irrigation scheme on Manjira river and the largest in the then Hyderabad state taken up during the year 1923 and completed by the year 1931. This Project was originally contemplated for utilization of 58.00 TMC of water to irrigate275,000 acres (111,000 ha) acres in Banswada, Bodhan, Nizamabad and Armoor Taluks of Nizamabad District. After reorganization of States in 1956, the Manjira basin

3024-583: Is used for irrigation in agriculture, the nutrient (nitrogen and phosphorus) content of the treated wastewater has the benefit of acting as a fertilizer . This can make the reuse of excreta contained in sewage attractive. In developing countries , agriculture is increasingly using untreated municipal wastewater for irrigation – often in an unsafe manner. Cities provide lucrative markets for fresh produce, so they are attractive to farmers. However, because agriculture has to compete for increasingly scarce water resources with industry and municipal users, there

3108-556: Is usually not considered as a form of irrigation. Rainwater harvesting is the collection of runoff water from roofs or unused land and the concentration of this. Irrigation with recycled municipal wastewater can also serve to fertilize plants if it contains nutrients, such as nitrogen, phosphorus and potassium. There are benefits of using recycled water for irrigation, including the lower cost compared to some other sources and consistency of supply regardless of season, climatic conditions and associated water restrictions. When reclaimed water

It remains untapped as its course is principally through dense forests and other ecologically sensitive zones such as wildlife sanctuaries . The Kaleshwaram Lift Irrigation Project

3444-573: The commercial greenhouse production, usually for potted plants . Water is delivered from below, absorbed by upwards, and the excess collected for recycling. Typically, a solution of water and nutrients floods a container or flows through a trough for a short period of time, 10–20 minutes, and is then pumped back into a holding tank for reuse. Sub-irrigation in greenhouses requires fairly sophisticated, expensive equipment and management. Advantages are water and nutrient conservation, and labor savings through reduced system maintenance and automation . It

3528-423: The Manjira river and three more are under construction. Similarly, Maharashtra state constructed at least 30 barrages on main tributaries of Manjira river downstream of major dams for recharging ground water, drinking water and irrigation purposes. This very old major irrigation project has become unproductive for want of water inflows. Also the water quality / salinity & alkalinity of inflows into this reservoir

3612-760: The Nile river in Egypt and Sudan; and in the Mississippi-Missouri river basin, the Southern Great Plains, and in parts of California in the United States. Smaller irrigation areas are spread across almost all populated parts of the world. By 2012, the area of irrigated land had increased to an estimated total of 3,242,917 km (801 million acres), which is nearly the size of India. The irrigation of 20% of farming land accounts for

3696-482: The Scheme is constructed without following the statuary provisions with regard to environmental aspects. Four major pumping facilities manage the project's outflow, the largest at Ramadugu ( Medaram , Annaram and Sundilla being the others) is also likely to be the largest in Asia once consistent measurements are available, requiring seven 140  MWh (500  GJ ) pumps designed and manufactured specifically for

3948-469: The center pivot. This type of system is known as LEPA (Low Energy Precision Application). Originally, most center pivots were water-powered. These were replaced by hydraulic systems ( T-L Irrigation ) and electric-motor-driven systems (Reinke, Valley, Zimmatic). Many modern pivots feature GPS devices. A series of pipes, each with a wheel of about 1.5 m diameter permanently affixed to its midpoint, and sprinklers along its length, are coupled together. Water

4032-485: The centre of the wheel line) rotates the clamped-together pipe sections as a single axle, rolling the whole wheel line. Manual adjustment of individual wheel positions may be necessary if the system becomes misaligned. Wheel line systems are limited in the amount of water they can carry, and limited in the height of crops that can be irrigated. One useful feature of a lateral move system is that it consists of sections that can be easily disconnected, adapting to field shape as

Thus, the settled ayacut of 275,000 acres (111,000 ha) has come down to 231,339 acres (93,620 ha). The local people believe that everyone should visit this place at least once in whole life to make it complete. In view of

4200-711: The components of these irrigation systems are hidden under ground, since aesthetics are important in a landscape. A typical lawn sprinkler system will consist of one or more zones, limited in size by the capacity of the water source. Each zone will cover a designated portion of the landscape. Sections of the landscape will usually be divided by microclimate , type of plant material, and type of irrigation equipment. A landscape irrigation system may also include zones containing drip irrigation, bubblers, or other types of equipment besides sprinklers. Although manual systems are still used, most lawn sprinkler systems may be operated automatically using an irrigation controller , sometimes called

As of June 2019, lifts are being commissioned with provision to lift 2 TMC ( 56,63,36,93,184 liters ) of water per day from Medigadda. The water is lifted to backwaters of Annaram barrage. Again from Annaram barrage to Sundilla barrage. Finally from Sundilla to Sripada Yellampalli Project. Civil works are being executed to lift 3 TMC per day but pumps are being installed to lift only 2 TMC. If need be, only pumps would need to be installed to increase capacity by one more TMC.

4368-408: The crop or field requirements. Increasing the application efficiency means that the amount of crop produced per unit of water increases. Improved efficiency may either be achieved by applying less water to an existing field or by using water more wisely thereby achieving higher yields in the same area of land. In some parts of the world, farmers are charged for irrigation water hence over-application has

4452-410: The entire field uniformly with water, so that each plant has the amount of water it needs, neither too much nor too little. Water use efficiency in the field can be determined as follows: Increased irrigation efficiency has a number of positive outcomes for the farmer, the community and the wider environment. Low application efficiency infers that the amount of water applied to the field is in excess of

4536-502: The exception of low-energy center pivot systems and surface irrigation systems, and the system can be designed for uniformity throughout a field or for precise water delivery to individual plants in a landscape containing a mix of plant species. Although it is difficult to regulate pressure on steep slopes, pressure compensating emitters are available, so the field does not have to be level. High-tech solutions involve precisely calibrated emitters located along lines of tubing that extend from

4620-433: The financial viability of the project. A recent report by the comptroller and auditor general of India (CAG) has pointed out that the cost to benefit ratio of the project is 1:0.75 in contrast to the state govt.'s claim of 1:1.5. In addition, by taking in to account the escalated costs for lifting the third TMC, the ratio comes down to 1:0.52. According to the report, the annual operational costs for irrigating an acre of land

4704-447: The foreshore waters of SRSP, water will be transferred to reservoirs at Hangarga and Dilwapur villages. Apart from this, existing reservoirs like Masani Tank and kondem Cheruvu will also be linked. Canals under Nizam Sagar will also be irrigated. The chief minister has said that every year about 400 TMC of water will be lifted. The project requires about 5,900 MW of electricity to run its several large water pumps. Assuming, on average,

4788-519: The gates of Babhali barrage remain lifted during the monsoon season, i.e., 1 July to 28 October and there is no obstruction to the natural flow of Godavari river during monsoon season below the three dams (Paithan, Siddheshwar & Nizamsagar dams) mentioned in Clause II (i) of the agreement dated 06.10.1975 towards Pochampad dam. Thus Pochampadu reservoir is accorded first priority over any other reservoir (major, medium, minor, barrage, etc.) to receive

4872-534: The ground. In flower beds or shrub areas, sprinklers may be mounted on above ground risers or even taller pop-up sprinklers may be used and installed flush as in a lawn area. Hose-end sprinklers are devices attached to the end of a garden hose, used for watering lawns, gardens, or plants. They come in a variety of designs and styles, allowing you to adjust the water flow, pattern, and range for efficient irrigation. Some common types of hose-end sprinklers include: Oscillating Sprinklers: These spray water back and forth in

4956-409: The image that follows. As of 2017 most center pivot systems have drops hanging from a U-shaped pipe attached at the top of the pipe with sprinkler heads that are positioned a few feet (at most) above the crop, thus limiting evaporative losses. Drops can also be used with drag hoses or bubblers that deposit the water directly on the ground between crops. Crops are often planted in a circle to conform to

5040-472: The inflows into Nizamsagar Project and as well as the low flows at Ghanpur Anicut during lean periods have dwindled considerably. Added to this the silting of reservoir has been at greater pace than designed for. From the investigation conducted by the A,.P.E.R.L. (Andhra Pradesh Engineering and Research Laboratories) Hyderabad in 1973, it was shown that the capacity of 29.7 TMC at original FRL of RL + 1,400.50 ft (426.87 m) has been reduced to 11.8 TMC. In

5124-490: The irrigation results in flooding or near flooding of the cultivated land. Historically, surface irrigation is the most common method of irrigating agricultural land across most parts of the world. The water application efficiency of surface irrigation is typically lower than other forms of irrigation, due in part to the lack of control of applied depths. Surface irrigation involves a significantly lower capital cost and energy requirement than pressurised irrigation systems. Hence it

5208-399: The level of the land. Surface irrigation is even used to water urban gardens in certain areas, for example, in and around Phoenix, Arizona . The irrigated area is surrounded by a berm and the water is delivered according to a schedule set by a local irrigation district . A special form of irrigation using surface water is spate irrigation , also called floodwater harvesting. In case of
