Water supply and sanitation in Iran has witnessed some important improvements, especially in terms of increased access to urban water supply, while important challenges remain, particularly concerning sanitation and service provision in rural areas. Institutionally, the Ministry of Energy is in charge of policy and provincial companies are in charge of service provision.
The sector is characterized by a wide discrepancy in coverage of water and sewerage services, as well as between urban and rural areas. The Joint Monitoring Programme for Water Supply and Sanitation of the WHO and UNICEF, which monitors access figures based on national surveys and censuses, estimated access in Iran from the results of the censuses of 1996, 2006, and 2011 as well as a 1995 Multiple Indicator Cluster Survey. According its estimates, in 2011 access to an improved water supply was 98% in urban areas where more than two thirds of Iranians live. It was 90% in rural areas (87% house connections). Access to sewerage in urban areas was estimated at 19% in the late 1990s. Access to improved sanitation was estimated at close to 100%. [1]
Rainfall in Iran is highly seasonal, with a rainy season between October and March, leaving the land parched for the remainder of the year. Immense seasonal variations in flow characterize Iran's rivers. For example, the Karun River in Khuzestan carries water during periods of maximum flow that is ten times the amount borne in dry periods. In numerous localities, there may be no precipitation until sudden storms, accompanied by heavy rains, dump almost the entire year's rainfall in a few days. Water shortages are compounded by the unequal distribution of water. Near the Caspian Sea, rainfall averages about 1,280 mm per year, but in the Central Plateau and in the lowlands to the south it seldom exceeds 100 mm. [2]

Internal renewable water resources are estimated at 128.5 billion cubic meters (BCM)/year (average for 1977-2001). [4] Surface runoff represents a total of 97.3 BCM/year, of which 5.4 BCM/year comes from drainage of the aquifers and thus needs to be subtracted from the total. Groundwater recharge is estimated at about 49.3 BCM/year, of which 12.7 BCM/year is obtained from infiltration in the river bed and also needs to be subtracted. Iran receives 6.7 BCM/year of surface water from Pakistan and some water from Afghanistan through the Helmand River. The flow of the Arax river, at the border with Azerbaijan, is estimated at 4.6 BCM/year. The surface runoff to the sea and to other countries is estimated at 55.9 BCM/year. [5] [6] Per capita water availability in the pre-Islamic Revolution era was about 4,500 cubic meters. But, in 2009 this figure was less than 2,000 cubic meters. [7] The total water withdrawal was estimated at about 70 BCM in 1993, rising to 93 BCM in 2004, [8] of which 92% was used for agricultural purposes, 6% for domestic use and 2% for industrial use. Although this is equal to 51% of the actual available renewable water resources, annual abstraction from aquifers (57 BCM in 1993, 53 BCM in 2004) is already more than the estimated safe yield (46 BCM). [5] Of the 4.3 BCM/year in 1993 (6.2 in 2004) used for domestic purposes, 61% is supplied from surface water and 39% from groundwater. [9] As of 2014, Iran is using 70% of its total renewable freshwater, far above the upper limit of 40% recommended according to international norms. [10] A large part of the water used in agriculture is evaporated instead of properly used because of inefficient consumption patterns. [11] 16 BCM of water was used for power generation in 1999. [8]
Tehran with its population of about 9 million is supplied by surface water from the Lar dam on the Lar River in the Northeast of the city, the Latyan dam on the Jajrood River in the North, the Karaj River in the Northwest, as well as by groundwater in the vicinity of the city. The average Tehran resident uses 325 liters of water (86 gallons) per day. [12] Tap water consumption in the country is 70% over and above the global average. [13]
In March 2016 President Hassan Rouhani said at a conference that the "water consumption pattern" in Iran had to be changed, without making any specific recommendations on how this could best be achieved. [14]
The Iranian government envisages massive investments in seawater desalination and in pipelines to bring water from the Southern shores to the interior of the country. In a first stage, desalination plants are to be built to supply coastal cities, while in a second stage cities on the central plateau are to be served as well. The plants and pipelines are expected to be financed by the private sector under Build-Own-Operate (BOO) Contracts where the government pays annual fees for the water produced. Such contracts for desalination plants already exist on a small scale with Iranian companies and are expected to be extended to larger contracts with international companies. [15] The power for the desalination plants is expected to be provide at least partly by "small" nuclear power plants.[ citation needed ] Iranian Energy Minister Hamid Chitchian said that desalinated water would be provided to 45 million people in 17 provinces through 50 desalination plants, without specifying the costs or funding sources. Initially, water desalinated at Bandar Abbas would be transferred to Kerman Province. [16]
Water pollution is caused by industrial and municipal wastewater, as well as by agriculture. Concerning municipal wastewater, the bulk of collected sewage is discharged untreated and constitutes a major source of pollution to groundwater and a risk to public health. In a number of cities without sanitary sewerage, households discharge their sewage through open rainwater drains. [17]
Most drinking water in Iran is supplied through modern infrastructure, such as dams, reservoirs, long-distance transmission pipelines - some of which are more than 300 km long - and deep wells. There are 42 large dams under operation in Iran with a combined storage capacity of 33 BCM/year. These dams lose about 200 million cubic meters of storage capacity every year due to sedimentation (0.5-0.75% of their storage capacity). Most dams are multi-purpose dams for hydropower, irrigation, flood control and - in some cases - drinking water supply. [18]
It is estimated that there are as many as 500,000 deep and shallow wells in the country. [19] Many of those wells are illegal. [11]
An estimated 60,000 traditional Karez (کاریز) systems in the plateau regions of Iran in Yazd, Khorasan and Kerman - are still in use today for irrigation and drinking water supply in rural areas and small towns. [2] The oldest and largest known Karez is in the Iranian city of Gonabad which after 2700 years still provides drinking and agricultural water to nearly 40,000 people. Its main well depth is more than 360 meters and its length is 45 kilometers.
Iran's Energy Ministry reported in January 2021 that some 90% of Tehran’s integrated sewage system, a network of 8,000 kilometers of underground tunnels and large sewage treatment facilities, has become operational.[ citation needed ]
Previously, the majority of Tehran's population had untreated sewage injected to the city's groundwater. [20]
Up to 1990 the water and sanitation sector was highly decentralized. Most water and wastewater service provision was the responsibility of municipalities and provinces. This was changed through a fundamental sector reform in 1990 with the ratification of the Provincial Water and Wastewater Companies Law of September 1990. [21]
In September 2003 the Government of Iran and the World Bank agreed on a sector strategy with the targets for improved cost recovery and collection and increased efficiency. It is not clear what were the baseline data in 2003 and to what extent progress has been made to reach these targets. [22]
In November 2008 the government announced that it has approved the construction of 177 dams nationwide. [23] Dams in Iran serve primarily for hydropower generation, irrigation and flood control. However, one of the projects will provide drinking water and water for industrial use to the cities of Qom, Golpaygan, Delijan, Saveh, Khomein and Nimvar in the central provinces of Qom, Isfahan and Markazi.
In April 2012, the government launched a project to transfer Caspian Sea water to the central regions of Iran, bringing about 200 million cubic meters (7,062 million cubic feet) of water per year. [24]
In April 2016 Deputy Minister of Energy Sattar Mahmoudi said that six major cities - Bandar Abbas, Shiraz, Kerman, Mashhad and Hamadan - faced acute water shortages, and water resources were under strain in another 450. Parts of Iran have faced droughts for the past 15 years. [16]
Since the 1980s access to urban water supply has increased from 75.5% to 98%. According to one Iranian observer, the water quantity supplied has increased and the quality has improved. He concludes that the reform has been “very successful” and is “an example of best practice” that should “be proposed to other countries. [9]
According to the World Bank, the sector is affected by “low water use efficiency in urban and rural uses; limited participation by stakeholders in development planning and management; large needs for rehabilitation and development of hydraulic infrastructure for sustainable water usage; problems of pollution caused by the discharge of untreated wastewater into public waterways and aquifers; and weak institutions involved in the sector and limited coordination among stakeholders.” [17] Still according to the World Bank it is also characterized by “poor performance of water supply and on-site wastewater disposal facilities, causing increasing risk for ground and surface water pollution and health and environmental risks resulting from the discharge and re-use of untreated effluent for irrigation; limited technical, institutional and financial capacity of water and wastewater companies; a lack of clarity of institutional responsibilities of sector entities; and non transparent and inadequate tariff structures and levels.” [25]
The Ministry of Energy, through its Deputy Ministry for Urban and Rural Water and Wastewater Management, is in charge of setting sector policies. The Deputy Ministry of Water Affairs in the same Ministry is in charge of water resources management, together with eleven Regional Water Boards. The Environmental Protection Organization is in charge of water pollution control. The Ministry of Health and Medical Education is responsible for setting drinking water quality standards, as well as monitoring and enforcing them. [21] [26] The National Water and Wastewater Engineering Company (NWWEC) provides oversight and assistance to service providers in areas such as investment planning, human resources development, and in the establishment of standardized systems and procedures. The National Economic Council sets tariff policy for the whole country, with some differentiation across regions. [27]
In 2008 sixty companies were responsible for the provision of water and wastewater services. Evenly spread over Iran's thirty provinces, each province has one urban and one rural water and wastewater company (WWC). The 60 companies had 38,000 employees. [28] Only Tehran has two separate companies for water and sewerage. In all other provinces, water and sanitation services are provided together. The regional water boards provide bulk raw water through transmission pipelines to the water and wastewater companies, which treat and distribute it.
The state-owned WWCs are able to manage their day-to-day operations with a measure of autonomy where Managing Directors can make most decisions on operations and staffing within the limits of the centrally authorized staffing levels and with some flexibility to provide extra compensation to well-performing employees. However, the WWCs do not control their own investment programs and, therefore, have limited scope to improve investment and operating efficiency and the level and quality of service. Moreover, the WWCs have to follow an organizational model developed by the NWWEC and cannot select a model that would be more appropriate for their particular situation. [29]
Until 2005, the national budget for the water sector stood at 1,400 billion rials while it has reached 3,500 billion rials (US$350 million using the official exchange rate) in 2008. [30] This budget apparently includes a multi-purpose dam and irrigation as well as water supply and sanitation. The government said in 2011 that investment needs stood at US$150 billion over the next 15 years, 20% of which should be financed by the private sector. [31]
On average, the service providers do not recover operation and maintenance costs due to low tariffs and low bill collection. For example, the Provincial Water and Sewerage Companies for Ahwaz and Shiraz have been incurring significant net losses at least prior to 2004. The financial performance of the companies is further aggravated by high water losses of 38% in 2002/03 in Ahwaz and about 30% in Shiraz. Of the water that has been billed, only about 73% was collected in 2002/03 in Ahwaz, while it was higher in Shiraz.
The current urban tariff system is based on a fixed fee that depends on the size of the connection pipe and on the type of customer (household or other types), and on a volumetric charge based on increasing block-tariffs. The fixed fee, or the subscription fee, was about 2,000 Rials in 2004 (25 US cents) for most domestic customers while the structure of variable tariffs is based on a complex formula. The formula is the same for all companies and there is no volumetric charge if consumption falls below 5 cubic meter per month. Above this minimum, the tariff increases with the level of consumption and generally varies across companies. The average volumetric tariff for the country stood at about 6 US cents in 2002. It varied from 2 cents for monthly consumption below 20 cubic meter, to about 4.5 cents and 12.5 cents respectively for 20-40 and for more than 40 cubic meter of monthly consumption.
According to the World Bank, the rate structure is needlessly complex for both volumetric rates and connection fees. Volumetric tariffs are based on complex formulas that differ across consumption brackets and water and wastewater companies. Because of this complexity the tariff structure lacks transparency. Moreover, the structure is such that rates increase by more than threefold when consumption rises from 20 cubic meter or less to slightly higher volumes. Regarding sewage bills they are currently levied and collected only in neighborhoods where a network exists and are a percentage of water bills (70%).
Average connection fees are about US$310 for the whole country and the minimum fee is approximately equal to US$150. With a few exceptions, the connection fee for wastewater is the same as that for water. These fees have been regularly increased between 1999 and 2003, at the rate of 10% annually with the exception of the year 2000 in which the fee was increased by 15%. In addition to connection fees, the water and wastewater companies charge the customer the full cost for house connection. [32]
The main external partner of the Iranian water and sanitation sector during the first decade of the 21st century was the World Bank. Today the main external partners are the Islamic Development Bank, the United Nations and NGOs.
The Islamic Development Bank (IDB) has allocated more than 800 million euros of loans in total for Iran's water and wastewater projects as of 2014, including 65 million euros for eastern Mashhad's wastewater project, 140 million euros for projects in the cities of Qom and Kashan in central Iran, 175 million euros to Tehran, 195 million euros to rural wastewater projects and 92 million euros to Qom province's water project, 80 million euros for wastewater projects in Hamedan and Qeshm, and 144 million euro for wastewater projects in the southern Fars province. [33] The Iranian wastewater sector is the largest recipient of IDB water and wastewater funds in the world, as the IDB has funded some of the gap caused by international sanctions. [34] With 8.28% of the shares Iran is the third-largest shareholder of the IDB, whose largest shareholder is Saudi Arabia. [35]
UNESCO-IHE in Delft, The Netherlands, together with the Power and Water University of Technology (Shahid Abbaspour) in Iran, will train 2,100 Iranian professionals in water and wastewater technologies, planning and management. The training will consist of 59 courses to take place in 2008 and the first half of 2009. In addition, 20 study tours to European water and wastewater companies for senior managerial, financial and technical staff will be organized. [28]
Unlike other lower and middle-income countries, Iran hosts few private international non-governmental organizations that pursue environmental or social aims. Despite the difficult operating environment and friction with ruling bodies, the Iranian Government has moved to encourage an increased participation by foreign NGOs. [36] As a result, some organizations that closed operations have resumed their activities, and new startup organizations, including those that work in the areas of water and sanitation, have initiated projects in Iran. One such organization, Healing For Iran, recently launched a program to improve rural access to water and investigate the causes of water contamination in disadvantaged populations. [37]
The World Bank was engaged in water and sanitation in the Islamic Republic of Iran between 2000 and 2010. Its engagement began with the approval of the Tehran Sewerage Project in 2000, followed by the approval of two other projects in 2004 and 2005. In 2010 its last project, The Northern Cities Water Supply and Sanitation Project, closed. The project, supported by a US$224m loan, aimed to enhance the quality of life in the four northern cities of Rasht and Anzali in Gilan Province, as well as Sari and Babol in Mazandaran Province. It aimed to do so by improving the operational efficiency and financial sustainability of the two Provincial Water and Wastewater Companies (WWCs). The project financed the extension and improvement of water distribution systems including metering, sanitary sewers, and a wastewater treatment plant (in Sari) which was not completed at project closure. [17] The project did not succeed in improving the financial situation of the two water and wastewater companies, since tariff increases were delayed. [38]
The Ahvaz and Shiraz Water Supply and Sanitation Project, supported by a US$279m loan approved in 2004 and closed in 2009, aimed to improve access to satisfactory water supply and significantly increasing coverage of sanitation services; and improve environmental, hygiene and health conditions, as well as promoting reuse of treated effluents. It also aimed to strengthen and develop the capacity of Ahvaz and Shiraz Water and Wastewater Companies, and assist the latter in improving their efficiency, sustainability and financial autonomy. It also aimed to initiate sector reforms, particularly with respect to institutional arrangements, the regulatory framework, demand management, as well as prepare a sanitation strategy. [39]
The Tehran Sewerage Project, supported by a US$145m loan, closed in 2008. Its objective was to improve the environmental conditions in the Greater Tehran area through the installation of wastewater collection and treatment facilities, to improve public health, and enable unrestricted irrigation practices in the surrounding areas. Chlorination would disinfect effluents treated at the secondary level for suitable irrigation purposes, and a further tertiary treatment was to be extended if required. Treated effluents, and sludge were to be reused for agricultural purposes. [40] The project allowed to connect more than 1.3 million people to the sewer system and to build a wastewater treatment plant that was completed in June 2009. A World Bank completion report concluded that the project reached its objectives and performed satisfactorily. [41]
The World Bank says that international financial institutions are exempt from the sanctions imposed by the UN on Iran. [42] In September 2013, the World Bank removed Iran from its list of borrowers that cannot receive new loans, saying the Islamic Republic had paid outstanding loan amounts. In April 2014, Iranian Finance and Economic Affairs Minister Ali Tayyebnia asked the World Bank to provide Iran with financial assistance to implement development projects. [43]
Access to at least basic water increased from 94% to 97% between 2000 and 2015; an increase in access to at least basic sanitation from 73% to 86% in the same period;
Drinking water and sanitation in Nicaragua are provided by a national public utility in urban areas and water committees in rural areas. Despite relatively high levels of investment, access to drinking water in urban areas has barely kept up with population growth, access to urban sanitation has actually declined and service quality remains poor. However, a substantial increase in access to water supply and sanitation has been reached in rural areas.
Drinking water supply and sanitation in Argentina is characterized by relatively low tariffs, mostly reasonable service quality, low levels of metering and high levels of consumption for those with access to services. At the same time, according to the WHO, 21% of the total population remains without access to house connections and 52% of the urban population do not have access to sewerage. The responsibility for operating and maintaining water and sanitation services rests with 19 provincial water and sewer companies, more than 100 municipalities and more than 950 cooperatives, the latter operating primarily in small towns. Among the largest water and sewer companies are Agua y Saneamientos Argentinos (AYSA) and Aguas Bonarenses S.A. (ABSA), both operating in Greater Buenos Aires, Aguas Provinciales de Santa Fe, and Aguas Cordobesas SA, all of them now publicly owned. In 2008 there were still a few private concessions, such as Aguas de Salta SA, which is majority-owned by Argentine investors, and Obras Sanitarias de Mendoza (OSM).
Water supply and sanitation in Venezuela is currently limited and many poor people remain without access to piped water. Service quality for those with access is mixed, with water often being supplied only on an intermittent basis and most wastewater not being treated. Non-revenue water is estimated to be high at 62%, compared to the regional average of 40%. The sector remains centralized despite a decentralization process initiated in the 1990s that has now been stalled. Within the executive, sector policies are determined by the Ministry of Environment. The national water company HIDROVEN serves about 80% of the population.
The water and sanitation sector in Peru has made important advances in the last two decades, including the increase of water coverage from 30% to 85% between 1980 and 2010. Sanitation coverage has also increased from 9% to 37% from 1985 to 2010 in rural areas. Advances have also been achieved concerning the disinfection of drinking water and in sewage treatment. Nevertheless, many challenges remain, such as:
The Dominican Republic has achieved impressive increases in access to water supply and sanitation over the past two decades. However, the quality of water supply and sanitation services remains poor, despite the country's high economic growth during the 1990s.
Water supply and sanitation in Saudi Arabia is characterized by challenges and achievements. One of the main challenges is water scarcity. In order to overcome water scarcity, substantial investments have been undertaken in seawater desalination, water distribution, sewerage and wastewater treatment. Today about 50% of drinking water comes from desalination, 40% from the mining of non-renewable groundwater and only 10% from surface water in the mountainous southwest of the country. The capital Riyadh, located in the heart of the country, is supplied with desalinated water pumped from the Arabian Gulf over a distance of 467 km. Water is provided almost for free to residential users. Despite improvements, service quality remains poor, for example in terms of continuity of supply. Another challenge is weak institutional capacity and governance, reflecting general characteristics of the public sector in Saudi Arabia. Among the achievements is a significant increases in desalination, and in access to water, the expansion of wastewater treatment, as well as the use of treated effluent for the irrigation of urban green spaces, and for agriculture.
Water supply and sanitation in Panama is characterized by relatively high levels of access compared to other Latin American countries. However, challenges remain, especially in rural areas. Panama has a tropical climate and receives abundant rainfall, yet the country still suffers from limited water access and pollution. Intense El Niño periods, periodic droughts, reduce water availability. Multiple factors like urbanization, impacts of climate change, and economic development have decreased water resources. The high frequency of floods in recent years and the lack of corresponding measures resulted in tension among the local population. Rapid population growth in recent decades led to an unprecedented increase in freshwater demand. Regional inequality exists in water resources and water governance. An estimated 7.5-31% of Panama's population lives in isolated rural areas with minimal access to potable water and few sewage treatment facilities.
While Peru accounts for about four per cent of the world's annual renewable water resources, over 98% of its water is available east of the Andes, in the Amazon region. The coastal area of Peru, with most of economic activities and more than half of the population, receives only 1.8% of the national freshwater renewable water resources. Economic and population growth are taking an increasing toll on water resources quantity and quality, especially in the coastal area of Peru.
The Philippines' water supply system dates back to 1946, after the country declared independence. Government agencies, local institutions, non-government organizations, and other corporations are primarily in charge of the operation and administration of water supply and sanitation in the country.
Water privatization in Metro Manila began when the then President of the Philippines, Fidel Ramos, instructed the government in 1994 to solve what he called the water crisis in Manila by engaging with the private sector. In 1997, two concession contracts for the Eastern and Western halves of Metro Manila were awarded after an open competition. The concessions represent the largest population served by private operators in the developing world. Both winning companies, Maynilad Water Services in West Manila and especially Manila Water in East Manila, submitted bids with extremely low water tariffs. The tariffs proved to be too low to finance the investments needed to improve performance, especially after the East Asian financial crisis and the devaluation of the Philippine Peso.
Public water supply and sanitation in Denmark is characterized by universal access and generally good service quality. Some salient features of the sector in the Denmark compared to other developed countries are:
Water supply and sanitation in Senegal is characterized by a relatively high level of access compared to most of Sub-Saharan Africa. One of its interesting features is a public-private partnership (PPP) that has operatedin Senegal since 1996, with Senegalaise des Eaux (SDE), a subsidiary of Saur International, as the private partner. It does not own the water system but manages it on a 10-year lease contract with the Senegalese government. Between 1996 and 2014, water sales doubled to 131 million cubic meters per year and the number of household connections increased by 165% to more than 638,000. According to the World Bank, "the Senegal case is regarded as a model of public-private partnership in sub-Saharan Africa". Another interesting feature is the existence of a national sanitation company in charge of sewerage, wastewater treatment and stormwater drainage, which has been modeled on the example of the national sanitation company of Tunisia and is unique in Sub-Saharan Africa.
Tunisia has achieved the highest access rates to water supply and sanitation services among the Middle East and North Africa. As of 2011, access to safe drinking water became close to universal approaching 100% in urban areas and 90% in rural areas. Tunisia provides good quality drinking water throughout the year.
Drinking water supply and sanitation in Egypt directly impact the country's public health, industrial developments, and agriculture. Egypt's water and sanitation industry is characterized by both achievements and challenges. Among the achievements are an increase of piped water supply between 1998 and 2006 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 at least basic water source in Egypt is now practically universal with a rate of 98%. On the institutional side, the regulation and service provision have been separated to some extensions through the creation of a national Holding Company for Water and Wastewater in 2004, and of an economic regulator, the Egyptian Water Regulatory Agency (EWRA), in 2006. Despite these successes, many challenges remain. Only about one half of the population is connected to sanitary sewers. Because of this low sanitation coverage, about 50,000 children die each year because of diarrhea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Furthermore, poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues.
Water supply and sanitation in Morocco is provided by a wide array of utilities. They range from private companies in the largest city, Casablanca, the capital, Rabat, Tangier, and Tetouan, to public municipal utilities in 13 other cities, as well as a national electricity and water company (ONEE). The latter is in charge of bulk water supply to the aforementioned utilities, water distribution in about 500 small towns, as well as sewerage and wastewater treatment in 60 of these towns.
Water supply and sanitation in Turkey is characterized by achievements and challenges. Over the past decades access to drinking water has become almost universal and access to adequate sanitation has also increased substantially. Autonomous utilities have been created in the 16 metropolitan cities of Turkey and cost recovery has been increased, thus providing the basis for the sustainability of service provision. Intermittent supply, which was common in many cities, has become less frequent. In 2004, 61% of the wastewater collected through sewers was being treated. In 2020 77% of water was used by agriculture, 10% by households and the rest by industry.
Water supply and sanitation in Lebanon is characterized by a number of achievements and challenges. The achievements include the reconstruction of infrastructure after the 1975–90 Civil War and the 2006 war with Israel, as well as the reform of the water and sanitation sector through a water law passed in 2000. The law created four Regional Water Establishments to consolidate numerous smaller utilities.
Water scarcity in Iran is caused by high climatic variability, uneven distribution of water, over exploitation of available water resources,and prioritization of economic development. Water scarcity in Iran is further exacerbated by climate change.
Water supply and sanitation in Georgia is characterized by achievements and challenges. Among the achievements is the improvement of water services in the capital Tbilisi where the water supply is now continuous and of good quality, major improvements in the country's third-largest city Batumi on the Black Sea where the country's first modern wastewater treatment plant now is under operation, as well as a general increase in access to drinking water in the entire country. Water and sewer tariffs remain affordable, with the private water company Georgian Water and Power (GWP) serving the capital being financially viable and profitable, while the public water company serving most of the rest of the country remains financially weak. The improvements were achieved after the Rose Revolution of 2004 when the government decided to reform the sector and to invest in it after many years of neglect.
