Uruguay is facing a hydro-social crisis. Countless water-related conflicts are occurring across the country, affecting water for human consumption and recreation, as well as damaging ecosystems.
In the capital, Montevideo and part of its metropolitan area, home to 1.7 million people, around 50% of the population, the water is , according to a statement made in early May by the country鈥檚 Minister for the Environment.
With these words the minister justified the decision to raise the level of salinity allowed in water for human consumption above the legally established standard in response to the water scarcity brought on by the drought that has . The legal limits of 200 milligrams per litre of sodium and 250 milligrams per litre of chlorides were raised to , respectively.
The water levels of the Paso Severino and Canel贸n Grande dams on the Santa Luc铆a River, which provide Montevideo鈥檚 drinking water, are no longer high enough to supply the population. Authorities have resorted to drawing water from the lower section of the river, which has higher salinity levels given its proximity to the mouth of the R铆o de la Plata.
, announced the decision in late April. Though authorities had been aware of the problem for months, they took no measures to explicitly communicate this to the public or any measures to prepare for the water and social emergency or prevent its effects.
A deluge of problems
The government鈥檚 initial statements in May, which recognised the situation but sought to minimise the problem, provoked a flood of concerns.
Professional groups warned of . Excessive sodium intake can cause heart and skin problems, among other issues.
This started a process of identifying affected people and processes, including in industry, business, educational institutions and hospitals. recommended, for example, not straining rice, reusing water used to cook pasta, giving children mineral water only if required (one glass per meal), and with mint, ginger, or rosemary to make it more palatable to children in early education centers 鈥 although the last recommendation was later rejected.
OSE鈥檚 water has historically been considered safe for consumption. In recent years, however, there has been episodes of bad taste or colour in tap water, and a growing number of middle- and upper-class households have begun using water filters and purifiers. These devices do not remove salt, however, and do not guarantee safe or flavourless water for consumption. For that, consumers need reverse osmosis technology, which is uncommon in Uruguay, except among some high-income sectors. For the majority of Montevideo鈥檚 population, access to potable water has become one more problem to deal with on a daily basis.
Mineral water bottling companies鈥 production and distribution capacity has been overwhelmed, leading to mineral water becoming scarce on some days and in certain places. For many, finding a way to access bottled mineral water has become necessary on a daily basis. For others this is not an option, as a 6-litre container of water costs on average $U3.20 ($A4.95). Additionally, this situation is producing an enormous amount of plastic waste.
Not an isolated problem
The drought alone does not explain the situation. A major political and partisan debate is growing around inefficiencies in management and foresight by the authorities. The right-wing coalition which has governed since 2020 started a process of reducing the number of state employees, which was particularly detrimental to OSE.
The opposition has also criticised the cancellation of a dam-building project in the department of Florida. By contrast, in March last year, OSE announced it had , to develop the Neptune project dropped by the previous government. This water treatment project, located in Arazat铆, department of San Jos茅, has the potential to supply the metropolitan area of Montevideo with 30% of its potable water.
and pleas for caution from organisations including the Federation of OSE Workers (FFOSE), REDES 鈥 Amigos de la Tierra (Friends of the Earth networks), various scientific groups, and even the Montevideo government.
The first criticism relates to the complications of taking water from the R铆o de la Plata. Issues of salinity, cyanobacteria (algae), and effects on the ecosystem make the water purification process very complex. Secondly, the Neptune project is seen as privatising water management 鈥 constitutionally forbidden under Article 47 of the Constitution, adopted by a popular referendum in 2004.
In addition to repeated cases of toxic cyanobacteria in the R铆o de la Plata and Uruguay River (in a country with high levels of both domestic and international beach tourism), all of the country鈥檚 major basins are registering alarmingly high levels of phosphorus and nitrogen.
Scientific studies indicate that the causes of these issues lie in inadequate sanitation and wastewater treatment and the use of very high levels of fertilisers and biocides in agriculture. There are long-standing objections to the effects the country鈥檚 agricultural model has had on the ecosystems it operates in.
Since the mid-1990s, agribusiness has pushed an intensification of agriculture that obeys the hegemonic logic of production, combining cross-sectoriality, prioritisation of global consumers, the generalisation, broadening and intensification of the role of capital in agrarian production processes, technological standardisation and land grabbing for large-scale production and a central role for large financial corporations.
In view of agribusiness鈥檚 growth over the last two decades, a new Irrigation Law (Law No. 16858) was presented in 2016. Although it set off alarms in academic sectors and among social movements, the bill enjoyed unanimous support in the parliament. In addition to criticisms related to the risks posed to ecosystems by the construction of large reservoirs, the law鈥檚 compliance with Article 47 was also called into question.
The Irrigation Law opened the possibility for actors within the financial system or external to productive systems to build, operate, manage, and charge for irrigation water. This was unprecedented and a substantial step towards the commodification of water, which cannot be analysed in isolation from the general (national and global) context of water markets.
Intertwined struggles
Environmental groups have mobilised in defense of water under the slogan 鈥No es sequ铆a, es saqueo鈥 (鈥淚t鈥檚 not drought, it鈥檚 looting鈥). In their view, the drought is just one more event in a cumulative process of water crises on a national level. One of these organisations, the Assembly for the Water of the Santa Luc铆a River (Asamblea por el Agua del R铆o Santa Luc铆a), has been particularly active in recent years, raising awareness of the river鈥檚 condition.
Organisations have held a . A march called by the PIT-CNT, Uruguay's national trade union centre, took place through downtown Montevideo, on May 31. The self-convened assembly that arose in response to the drinking water crisis and the coordinating committee of feminist organisations also endorsed the march.
2004 marked a turning point regarding water, its significance, and its management. After a year of major mobilisation primarily promoted by the National Commission in Defense of Water and Life (CNDAV), a popular referendum approved a constitutional reform of Article 47, declaring water a public good and access to potable water and sanitation human rights to be provided by public companies. Likewise, the reform stipulated that water resources should be managed by catchment basins and in a participatory manner.
This process took a distinctly urban and state-centric approach to water by making production of drinking water and its management central issues. Other kinds of water, or the connection between different waters (water for consumption, water for production, water for recreation, water for ecosystems, among others), were not given sufficient attention and were addressed separately at the institutional level.
Recently however, the widely held idea that water is abundant is being questioned. This is mainly due to conflicts emerging over its use and control, growing demand from certain economic sectors, large-scale electricity generation and the resulting degradation that limits its use for human consumption. Another factor is the state-level modification of acceptable water quality standards for human consumption.
This has opened up new dimensions for discussion and consideration. Water and its availability for agricultural use, for example, became an important issue, as have the effects of certain productive activities on water meant for other uses.
Mobilisation to repeal the new Irrigation Law did not secure the signatures necessary to enable a referendum, but it did begin to direct the debate towards an understanding of water as an interconnected whole.
Drinking water quality may improve in the near future. Regardless, one thing is certain: Uruguay is at a crossroads when it comes to water and all it implies for life.
