The Nile Delta is the delta formed in Northern Egypt where the Nile River spreads out and drains into the Mediterranean Sea. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers some 240 km of Mediterranean coastline—and is a rich...

, and in the Northern Sinai. These projects all require substantial amounts of water that can only be mobilized through better irrigation efficiency and reuse of drainage water and treated wastewater on already irrigated "old lands".

History

The history of modern water management in Egypt begins with the construction of the Old Aswan Dam in 1902 and barrages on the Nile in the 19th and early 20th century. The Old Aswan Dam partially stored the waters of the Nile to allow the growing of multiple crops per year in the Nile Delta, while the barrages raised the water level of the Nile so that water could be diverted into large irrigation channels running in parallel to the river. The water regime of the river was changed fundamentally in 1970 when the Aswan High Dam was completed, eliminating the annual Nile flood. The dam brought major benefits such as increased water availability for Egyptian agriculture including during drought years leading to higher income and employment, hydropower production, flood control, improved navigation, and the creation of fisheries in Lake Nasser. But it also had environmental and social impacts including resettlement, loss of fertile silt that now accumulates in the reservoir behind the dam, waterlogging and an increase in soil salinity, and increased coastal erosion.
Unrelated to the construction of the Aswan High Dam, water quality deteriorated through drainage return flows and discharges of untreated municipal and industrial wastewater. Beginning in the 1980s wastewater treatment improved and water quality in the Nile also gradually improved again. Until 1992 the government decided which crops farmers had to grow, which allowed it to deliver specific volumes of water to each canal based on the water needs of the crops. In 1992 a major change occurred when cropping patterns were liberalized and farmers were free to grow what they wanted. At the same time the government began to transfer the responsibility for the management of branch canals to water user associations, a process also called "irrigation transfer". In the mid-1990s the government also initiated three mega-projects to expand irrigation to "new lands" in the desert.

Existing infrastructure

Water resources management in Egypt depends on a complex set of infrastructure along the entire length of the river. The key element of this infrastructure is the Aswan High Dam that forms Lake Nasser
Lake Nasser

Strictly, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory , with the Sudanese preferring to call their smaller body of water...

. The High Dam protects Egypt from floods, stores water for year-round irrigation and produces hydro power.

Downstream of the Aswan Dam, there are seven barrages to increase the river's water level so that it can flow into first-level irrigation canals. One of them is the 350 km long Ibrahimiya Canal

, supplying drinking water to the cities along the Canal. Both canals were completed in 1863. The Mahmoudiya Canal links the Nile to Alexandria. Completed in 1820 it used to have an important role for navigation, but nowadays is used primarily for irrigation and to supply Alexandria with drinking water.
Irrigation canals are classified into principal canals (Rayah), main canals (first level canals), branch canals (second level canals), distribution canals (Mesqas, or third level canals) and irrigation ditches (Merwas). Flow in the principal and main canals is continuous; in the branch and distribution canals it is on a rotation basis. However, the government aims at converting some of the lower-level canals gradually to continuous flow. Farmers pump water from the mesqas to irrigate fields (lift: about 0.5-1.5 m). A Mesqa typically serves an area of 50 to 200 feddan
Feddan
A feddan is a unit of area. It is used in Egypt, Sudan, and Syria. The feddan is not an SI unit and in Arabic, the word means 'a yoke of oxen': implying the area of ground that could be tilled by them in a certain time. In Egypt the feddan is the only non-metric unit which remained in use...

 (20 to 80 hectares). In areas where there is no formal operational structure for proper water distribution, the tail-end users usually are not getting enough water to maintain crops. Water user associations have been formed beginning in the 1990s to better distribute water among farmers on a mesqa and to rationalize pumping, with the aim of reducing water abstraction, pumping costs and to increase yields.

In 1994 Egypt had approximately 30,000 km of public canals (first and second level), 17,000 km of public drains, 80,000 km of private third-level canals (mesqas) and irrigation ditches, 450,000 private water-lifting devices (sakia

The total investment cost in agricultural drainage over 27 years from 1973 to 2002 was about 3.1 billion US$ covering the cost of design, construction, maintenance, research and training. During this period 11 large scale projects were implemented with financial support from World Bank and other donors

Irrigation Improvement Program

Water savings in agriculture are an important objective of Egypt’s water strategy to serve a growing population with limited resources. However, the magnitude of potential water savings in agriculture and how best to achieve such savings have been a subject of some debate. While field-level irrigation efficiencies may be low due to the predominance of flood irrigation, the overall system efficiency is quite high due to return flows. Water savings strategies in Egypt therefore do not focus much on water-saving irrigation technologies such as sprinkler

. Instead they are based on the observation that when farmers lack control of the timing and quantities of water supply, they irrigate too soon and apply too much water.

The feasibility of water savings in Egyptian agriculture was first assessed through pilot projects under the USAID-supported Egypt Water Use and Management Project (EWUP) begun in 1977. The pilots showed that in order to achieve water savings, it was important to allow farmers to participate more in irrigation management through water user associations, to provide continuous flow instead of rotational flow in branch canals, to replace Mesqas, to replace individual by collective pumping, and to create an irrigation advisory service. The 1980 "Strategy for Irrigation Development in Egypt up to the year 2000" already envisaged the improvement of control and distribution of irrigation water as a first phase of the strategy, to be followed by the development of field irrigation systems and direct pricing of irrigation water were to be introduced at later stages. Based on the lessons of EWUP
and the irrigation strategy the government set out the National Irrigation Improvement Program (IIP) in 1984, which was approved by the National Assembly in 1985. Its implementation began, again with support from USAID, in eleven pilot areas, beginning with the Serri Canal with 120,000 feddan (50,400 hectares) in Minya Governorate
Minya Governorate

. The project replaced the old low-lying Mesqas either with raised Mesqas, from which water would flow to the fields via gravity, or with buried pressurized pipes. By 1998 about 1,100 water user associations had been formed and systems irrigating 129,000 feddan had been modernized. The project reduced water losses, improved water quality at the tail end of mesqas, made more water available to farmers at the tail end of canals, saved land due to the smaller size of the new mesqas, reduced pumping costs by more than 50% and increased yields between 5% and 30%. Building on this success the concept of farmer participation in irrigation management was extended to branch canals with the creation of Branch Canal Water Users Association (BCWUAs) beginning in 1997 in Qemri, Bahr el Dahram and Balaqtar branch canals (Lower Egypt) and El Reity canal (Upper Egypt), as well as in Fayoum.

 supported the IIP with the ultimate objective to increase agricultural production and income. As part of this project, 2906 water user associations were created irrigating more than 200 thousand feddan (84,000 hectares) in the Western Delta (Mahmoudia) and the Northern Delta (Manaifa and Wasat). However, net revenues increased only by 6-9% due to reduced pumping costs compared to a target of 30%, so that the project was rated as "marginally satisfactory" by the World Bank in 2007.

Beginning in 1996 the government also initiated the creation of drainage user associations (DUAs) to manage drainage canals collectively. However, these associations remained marginal and apparently farmers are not interested in organizing themselves in drainage matters only.

Mega-projects under construction

The North Sinai Development Project includes the Al-Salam Canal in front of Damietta Lock and Dam with the purpose of reclaiming 220 thousand feddans west of the Suez Canal, of which 180 thousand feddan are already irrigated. A siphon was built in 1997 under the Suez Canal to bring water to the Sinai through the Al-Sheikh Gaber Al-Sabah Canal to reclaim 400 thousand feddans east of the Suez Canal.

Future resources

It is forecasted that in 2025 the population of Egypt will increase from about 75 million in 2008 to about 95 million, leading to a decrease in per capita water availability from 800 to 600 m³ per year assuming that total water availability remains constant.

Developments in Sudan, Ethiopia or other riparian countries could reduce water availability to Egypt, for example through increased abstractions for irrigation. However, they could also increase water availability, for example through the draining of swamps such as the Sudd

 is likely to affect water availability to Egypt, although the direction of change is uncertain. According to Nahla Abou El-Fotouh of the National Water Research Centre (NWRC) “Some experts say that there will be water increase with more rainfall from the Ethiopian plateau, and some say there will be a decrease because of water evaporation." According to Mohamed al-Raey, a professor of environmental studies at Alexandria University, some studies foresee a decline of up to 70 percent in Nile water availability, while other studies project an increase in Nile water levels by 25 percent.

Brackish water desalination for irrigation may also become more important.

 (IPCC) expects the sea level to rise by up to 59 cm in the worst of all considered scenarios by 2100.
According to studies quoted by the IPCC, climate change could lead to the loss of a "sizable proportion of the northern part of the Nile delta" to "a combination of inundation and erosion". A 0.5-m rise in sea level would lead to estimated losses of land, installations, and tourism of more than US$32.5 billion in the Governorate of Alexandria alone, cutting off the city of Alexandria from the Delta. Erosion already increased in the Nile Delta since the construction of the Aswan High Dam in the 1970s which trapped much of the Nile sediments. Furthermore, agricultural land losses will occur as a result of soil salinization.

The extent of vulnerability of the Nile delta to increases in sea level varies. One study estimates that 30% of the Delta and Alexandria coast is vulnerable, 55% is "invulnerable" and 15% was artificially protected in 2003. High-risk areas in and near the Delta include parts of Alexandria, Behaira, Damietta and Port Said governorates. According to Omran Frihy, a retired coastal researcher, authorities are spending US$300 million to build concrete sea walls to protect the beaches of Alexandria. Sand is being dumped in some areas to replenish dwindling beaches.

Water use

The main water-using sector in Egypt is agriculture, followed by municipal and industrial uses. Total water withdrawal in 2000 was estimated at 68.3 km3.

Agriculture and reuse of drainage water

Data on agricultural water use in Egypt are not precise and often contradictory. The total area equipped for irrigation was 3.4 million hectares in 2002; 85 percent of this area is in the Nile Valley and Delta. Agriculture used about 59 km3 of freshwater in 2000 (86 percent of total use). All drainage water in Upper Egypt, south of Cairo, flows back into the Nile and the irrigation canals; this amount is estimated at 4 km3/yr. Drainage water in the Nile Delta is estimated at 14 km3/yr. As mentioned below about 10 km3/year of drainage water in the Delta that originates from freshwater is being pumped to the sea. Reuse of drainage water occurs in three different ways:
  • Official reuse through public pumping stations that pump water from drains to irrigation canals. This accounts for about 4.5 BCM/year in the Delta and 0.9 BCM/year in Upper Egypt and Faiyoum.
  • Unofficial reuse done by farmers themselves when they are short of canal water. In the Delta alone this has been estimated to be around 2.8 BCM/year.
  • Indirect reuse from drains in Upper Egypt that discharge into the Nile, amounting to about 4 BCM/year.

Municipal and industrial use

5.3 km3 of water was used for municipal uses (8 percent) and 4.0 km3 by industry (6 percent). It has been estimated that about 3.5 BCM/year of municipal waste water was being discharged into the Nile and the sea in 2002, out of which only 1.6 BCM/year (about 45%) were treated. Industrial effluents contribute to about 1.3 BCM/yr of waste water being discharged to surface waters, only some of which is being treated.

Other uses

Hydropower. An important use of water in Egypt is for the production of hydropower. This use is non-consumptive and is thus available for other uses further downstream. Hydropower plants exist at the Aswan High Dam (2100 MW), the old Aswan Dam (270 MW)and power plants at the Esna (90 MW) and Naga Hammadi weirs (64 MW). Together these plants accounted for 16% of installed electricity generation capacity in 2004. The share of hydropower in power generation declines since the hydropower potential is largely exploited and power demand increases rapidly.

Navigation. The Nile is also important for navigation, especially for tourism, which makes it necessary to maintain a minimum flow of the Nile year-round.

Ecology. Last but not least the Nile River also has ecological functions that require minimum flows to be maintained, especially for the brackish lakes in the Delta (see below under biodiversity).

Discharge to the sea. Drainage water that is too saline to be used for agriculture is discharged from drainage canals in the Delta to the sea and the northern lakes via drainage pump stations. The total amount of drainage water that was pumped to the sea in 1995/96 has been estimated at 12.4 BCM. This includes about 2.0 BCM/year of seawater that seeps into the drains in the Delta.

concentrations, which makes its water a reference point for water quality along the river and its branches. According to reports by the Egyptian Environmental Affairs Agency, in 2007 average organic loads in 11 governorates along the Nile remained below the allowed limit of 6 mg/liter of biological oxygen demand (BOD). This is due to the high self-assimilation capacity of the Nile. However, in the same year chemical oxygen demand

 was above the allowed limit of 10 mg/liter in 7 of 11 governorates. The report does not include data for some governorates on the Nile such as Monufia and Sharqia. The average level of dissolved oxygen was slightly higher than the allowed minimum of 5 mg/liter in all governorates. The report by the Environmental Authority only shows averages and does not indicate the frequency of standards violations.

A detailed study undertaken in 2002 by a research team working for the Ministry of Water and Irrigation and USAID confirms that the water quality of the Nile River was good despite high organic loads discharged from some of the drains and industrial activities. Water contamination is worst in drainage canals (drains), particularly in all drains in the Delta and some drains in Upper Egypt. The study ranks water pollutants according to their severity to public health and the environment: Pathogenic microorganisms are ranked first, followed by organic compounds. Pesticides and heavy metals are ranked third, while noting that very little information is available to quantify the magnitude of the problem.

 and employed roughly 17,000 workers. The government drained substantial portions of the lake in an effort to convert its rich Nile deposits to farmland. The project was unprofitable: crops did not grow well in the salty soil and the value of resulting produce was less than the market value of the fish that the reclaimed land had formerly yielded. By 2001, Lake Manzala had lost approximately 80 percent of its former area through the effects of drainage efforts.

Groundwater quality

Groundwater is contaminated from nitrogen and fertilisers (the use of which has quadrupled between 1960 and 1988) and the impact of pesticide and herbicide use, the latter being used to control weeds in canals. Shallow aquifers, in particular in the Nile Delta, are often heavily contaminated.

Health impact

In villages where the only available water is from irrigation canals, water is used for domestic purposes and dumped back into the drains. Villagers drinking polluted water have been affected with kidney and liver diseases. The northeast Nile Delta region has a high incident rate of pancreatic cancer

Legal and institutional framework

Legal framework

There is no single overarching water resources law in Egypt. The main laws of relevance for water resources management include laws about irrigation and drainage on the one hand, and laws to protect the environment on the other hand. Among the irrigation and drainage laws are:
  • Law 12 for the year 1984 for the Irrigation and drainage, and
  • Law 213 for the year 1994 for farmer participation and cost sharing.


Among the laws and decrees for environmental protection are:
  • Law 93 for the year 1962 for the discharge to open streams and its modifications for the years 1962, 1982, and 1989,
  • Law 27 for the year 1978 for the regulation of water resources and treatment of wastewater,
  • Law 48 for the year 1982 Regarding the protection of the River Nile and waterways from pollution,
  • Law 4 for the year 1994 for Environment Protection.

Key institutions

Several ministries are involved in water resources management in Egypt. The Ministry of Water Resources and Irrigation (MWRI) plays a key role. It is in charge of development and management of water resources, and operating and maintaining dams, weirs, irrigation canals and drainage canals. It also monitors water quality. The Ministry of Agriculture and Land Reclamation (MALR) is involved in improving agricultural activities and land reclamation, including water management at the on-farm level. The Ministry of Housing, Utilities and New Communities (MHUNC) provides water supply and sanitation services. The Ministry of Health and Population (MoHP), the Ministry of State for Environmental Affairs (MSEA) and the Egyptian Environmental Affairs Agency (EEAA), and the Ministry of Local Development (MoLD) also have specific roles in the sector.

The important task of water quality monitoring is shared among MWRI, MoHP and MSEA. Each of the three Ministries has its own monitoring sites along the Nile and canals. Groundwater quality is monitored exclusively by MWRI. In addition, three institutes within the National Water Research Center monitor water quality. According to a UN report "Despite the multiplicity of (water quality monitoring) programmes, they have sometimes lacked accurate information and have not been linked up". To improve the quality of monitoring and reporting, Egypt has received support from the Canadian Association for Environmental Analytical Laboratories. Furthermore, a water quality unit has been established, which gathers water quality data from various sections of MWRI and other ministries and collects them in a database with "more than 40 indicators and covering more than 435 sites".

To ensure co-ordination among Ministries involved in water resources there are several committees, including the Supreme Committee of the Nile, headed by the minister of Water and Irrigation,the Committee for Land Reclamation and the Inter-Ministerial Committee on Water Planning. The latter was established in 1977 as a part of the Master Water Plan project.

The following authorities operate under MWRI:
  • The Egyptian Public Authority for the High Dam and Aswan Reservoir is responsible for operation of the Aswan High Dam.
  • The Egyptian Public Authority for Drainage Projects (EPADP) is responsible for the construction and maintenance of drains.
  • The Egyptian Public Authority for Shore Protection, also called Shore Protection Authority (SPA), is responsible for the planning of shore protection activities.
  • The National Water Research Center comprises 12 institutes and is the scientific body of MWRI for all aspects related to water resources management.

National water planning

The concept of formal long-term national water resources planning was introduced in Egypt through foreign technical assistance during the 1970s. In 1981 a Master Plan for Water Resources Development and Use was finalized with the support of UNDP and the World Bank

. Rather than being an actual plan, the document aimed at introducing planning tools such as data bases and flow models that would allow better planning. In subsequent years a number of events increased water scarcity. These include a drought in 1979-88; cessation in 1983 of construction works on the Jonglei Canal

 in Sudan; and a revitalization of a land reclamation program, requiring one billion m3 of additional water each year. These events helped trigger a greater emphasis on integrated long-term water planning. In 1990 the government adopted its first national water plan covering the period until 2000. Under the plan the government stopped releases of water from Lake Nasser that was only destined for power generation. It also decided to replace old barrages with new ones and it launched the National Irrigation Improvement Program. Furthermore, it aimed to increase the re-use of drainage water and the use of groundwater. On the demand side, water release to the sea at times of low water demand in winter for the sole purpose of maintaining navigation and to regulate sea water intrusion in the Delta was to be reduced. During the period of the plan land reclamation was to continue at a rate of 60,000 hectares per year. The Plan assumed that the Jonglei Canal would be built by 2000.
Some elements of the plan were implemented. Others – such as the Jonglei Canal – did not materialize or were delayed, such as the Irrigation Improvement Program.

Beginning in 1998 the Dutch government provided technical assistance to prepare a second national water plan. The National Water Resources Plan (NWRP) was completed in 2003 with a time horizon until 2017. The plan, which is not publicly available, is based on four principles: to develop additional resources, make better use of existing resources, protect public health and the environment, and improve institutional arrangements. According to the FAO

 the plan includes both "vertical expansion" through more efficient water use and increased agricultural productivity and "horizontal expansion" by increasing the existing agricultural area of 7.8 million feddan (about 3.12 million ha) by an additional 1.4 million feddan (about 560 000 ha). In June 2005 the Ministry presented an Integrated Water Resources Management Plan, which was prepared with technical assistance from the World Bank, as a "transitional strategy including further reform interventions" building on the NWRP. The Plan, which reads more like a World Bank report than a report by the Egyptian government, includes 39 actions in the fields of institutional reform and strengthening, policies and legislation, physical interventions, capacity building, technological and information systems, water quality, economic and financial framework, research, raising awareness, monitoring and evaluation and transboundary cooperation. The physical interventions mentioned include irrigation improvement and rural sanitation without mentioning the government's mega-projects that are at the heart of Egypt's actual water policy.

External cooperation

External cooperation has played an important role in shaping Egypt's modern water resources management through both investment financing and technical assistance.

Concerning investment financing, the Soviet Union financed the Aswan High Dam during the 1960s. After Egypt opened itself to the West in the 1970s, the United States, various European countries and the World Bank provided major investment financing for water supply and sanitation and for irrigation and drainage. The Gulf countries partially financed mega-projects to develop new lands for irrigation in the New Valley (supported by the United Arab Emirates) and in Northern Sinai (supported by Kuwait an Saudi Arabia). Concerning technical assistance, the Netherlands, the World Bank and UNDP played important roles in supporting successive national water master plans since the 1980s. UNDP and the National Water Research Center have developed a computer-supported Decision Support System
