The Right to Water Under International Law: Is Clean Water a Human Right?

Introduction

The right to water is recognized under international human rights law. Every person is entitled to sufficient, safe, acceptable, physically accessible, and affordable water for personal and domestic use. This recognition derives principally from existing human rights treaties, particularly the International Covenant on Economic, Social and Cultural Rights (ICESCR), and has been affirmed by the United Nations General Assembly. Access to clean drinking water is a human rights entitlement, although the binding obligations of individual states depend on the legal instruments applicable to them.

The legal foundations of this right require careful distinction. The ICESCR does not expressly establish a separate right to water, but the Committee on Economic, Social and Cultural Rights interpreted Articles 11 and 12 as encompassing that entitlement in General Comment No. 15, adopted in 2002. In July 2010, General Assembly Resolution 64/292 explicitly recognized safe and clean drinking water and sanitation as a human right. The resolution strengthened international recognition without itself creating a new binding treaty obligation (CESCR, 2002; United Nations General Assembly, 2010).

Recognition does not mean that governments must provide unlimited free water or immediately install household connections everywhere. International human rights law establishes requirements concerning water quality, accessibility, affordability, non-discrimination, and state conduct. Some obligations demand immediate compliance, while others involve progressive realization through appropriate measures and the use of available resources.

The distinction between legal recognition and enforceable guarantees is central to understanding the right to clean water. Treaty provisions, United Nations resolutions, interpretations by human rights bodies, and judicial decisions contribute to its protection, but they do not possess identical legal authority. Their relationship determines what individuals may claim, what governments are required to do, and how violations can be addressed.

1. The Legal Foundations of the Right to Water

The international protection of drinking water developed through rights that were recognized before water became an explicitly identified human rights entitlement. The Universal Declaration of Human Rights of 1948 proclaimed rights to life and an adequate standard of living without expressly naming a separate right to water. Later treaties established binding obligations concerning health, living conditions, and equality, providing the legal foundations for more specific water-related guarantees.

Access to safe drinking water is closely connected to the enjoyment of these rights. Contaminated supplies can threaten health and life, while insufficient water can undermine food preparation, personal hygiene, and adequate living conditions. The relationship is legally significant because the interpretation of an existing treaty right may encompass conditions necessary for its effective enjoyment, even where the original provision does not list every protected element.

The source of an obligation must nevertheless be identified separately from the importance of the interest it protects. Treaty commitments bind states parties under the relevant instruments, subject to their applicable provisions. Whether a freestanding right to water also exists in customary international law requires evidence of general state practice accepted as law, rather than international recognition alone. The clearest universal treaty foundation remains the ICESCR, supplemented by more explicit guarantees in specialized human rights conventions.

1.1 The ICESCR and Articles 11 and 12

The International Covenant on Economic, Social and Cultural Rights was adopted in 1966 and entered into force on January 3, 1976. Article 11(1) recognizes the right of everyone to an adequate standard of living, including adequate food, clothing, and housing, and to the continuous improvement of living conditions. Article 12 protects the right to the highest attainable standard of physical and mental health (ICESCR, 1966, arts. 11–12).

Neither provision expressly identifies water as an independent entitlement. The Committee on Economic, Social and Cultural Rights, however, interprets the examples listed in Article 11(1) as non-exhaustive. Drinking water is essential to an adequate standard of living and belongs within the guarantees contemplated by that provision. Article 12 provides an additional foundation because safe water contributes directly to disease prevention, environmental hygiene, and the protection of health.

The Committee developed this interpretation in General Comment No. 15, particularly paragraphs 2 and 3. It identified water as one of the fundamental conditions for survival and treated access to adequate supplies as an essential element of the rights protected by the Covenant. Its reasoning connects the material requirements of human life with the legal obligations arising from Articles 11 and 12 (CESCR, 2002, paras. 2–3).

The legal status of that interpretation is distinct from the Covenant itself. General Comments are authoritative statements of a treaty body's understanding of the instrument it supervises, but they do not amend treaty provisions or possess the same formal legal force as the treaty text. The right to water under the ICESCR rests on the Covenant's binding guarantees as interpreted by the Committee. The scope of an enforceable claim must still be assessed under the applicable legal system.

1.2 Explicit Water Protections in Human Rights Treaties

Several specialized international conventions refer expressly to water. Article 14(2)(h) of the Convention on the Elimination of All Forms of Discrimination against Women requires states parties to take appropriate measures to eliminate discrimination against women in rural areas and ensure their enjoyment of adequate living conditions, particularly concerning housing, sanitation, electricity, and water supply (CEDAW, 1979).

The provision addresses a specific form of inequality. Rural women may face disadvantages arising from inadequate infrastructure, unequal access to resources, and burdens associated with obtaining household water. Article 14 situates water supply within a wider obligation to secure equality in rural living conditions. It is an express treaty guarantee, although its scope is defined by the convention's protection against discrimination.

The Convention on the Rights of the Child provides another direct reference. Article 24(2)(c) requires states parties to pursue the full implementation of children's right to health, including measures to combat disease and malnutrition through adequate nutritious foods and clean drinking water, while considering the dangers and risks of environmental pollution. The provision establishes an explicit relationship between safe water and the protection of children's health (CRC, 1989).

Article 28(2)(a) of the Convention on the Rights of Persons with Disabilities requires states parties to ensure equal access to clean water services for persons with disabilities as part of the right to social protection. Its significance extends to the practical accessibility of services, including physical infrastructure and arrangements that may exclude individuals even where water supplies are generally available. These treaty provisions reinforce the recognition of water access, while imposing obligations within their respective legal contexts (CRPD, 2006).

2. General Comment No. 15 and United Nations Recognition

The development of the right to water within the United Nations involved two different institutional processes. The Committee on Economic, Social and Cultural Rights clarified the content of existing treaty obligations, while political bodies progressively affirmed water and sanitation as human rights in international resolutions. These processes were complementary, but their legal effects were not identical.

The distinction became particularly visible between 2002 and 2015. General Comment No. 15 supplied a detailed interpretation of water-related rights under the ICESCR. General Assembly Resolution 64/292 subsequently made explicit recognition of safe and clean drinking water and sanitation a matter of collective international declaration. Further resolutions clarified the distinct characteristics of the rights to water and sanitation.

These developments did not produce a new universal convention devoted exclusively to drinking water. Their importance lies in strengthening the interpretation and recognition of existing protections, establishing more specific expectations concerning state conduct, and giving water access a prominent position within international human rights institutions.

2.1 General Comment No. 15 (2002)

The Committee on Economic, Social and Cultural Rights adopted General Comment No. 15 during its twenty-ninth session in November 2002. The document was issued on January 20, 2003, under the symbol E/C.12/2002/11. It remains one of the principal international interpretations of the right to water under Articles 11 and 12 of the ICESCR.

Paragraph 2 defines the entitlement through five elements: sufficiency, safety, acceptability, physical accessibility, and affordability for personal and domestic uses. Paragraphs 10 to 12 develop its normative content, including protection against interference with existing supplies and access to systems that provide equitable opportunities to obtain water. The Committee also emphasizes that water should be treated as a social and cultural good, rather than primarily as an economic commodity (CESCR, 2002, paras. 2, 10–12).

The General Comment goes beyond identifying an entitlement. It addresses the responsibilities of states, the position of vulnerable groups, the regulation of third parties, remedies for violations, and international cooperation. Its treatment of essential water access is particularly significant because it identifies obligations the Committee considers necessary to give practical effect to the Covenant.

These interpretations have substantial legal influence, but the General Comment is not an independent treaty. Its statements concerning minimum core duties, non-derogability, and particular safeguards represent the Committee's interpretation of Covenant obligations. Their acceptance and judicial application may differ across legal systems, even where the underlying treaty provisions are binding upon the state concerned.

2.2 Resolution 64/292: Recognition and Legal Effect

On July 28, 2010, the United Nations General Assembly adopted Resolution 64/292, entitled The Human Right to Water and Sanitation. The resolution received 122 votes in favor, none against, and 41 abstentions. It recognized safe and clean drinking water and sanitation as a human right essential for the full enjoyment of life and all human rights (United Nations General Assembly, 2010).

The resolution also called upon states and international organizations to provide financial resources, capacity-building, and technology transfer through international assistance and cooperation, particularly to developing countries. It reflected recognition that inadequate infrastructure and limited resources could impede access even where governments accepted the importance of water and sanitation.

Resolution 64/292 had considerable diplomatic significance, but it was not a treaty. General Assembly resolutions of this character are not independently binding merely because they receive broad international support. Their legal relevance may include the expression of political commitments, influence on legal interpretation, and evidence relevant to the development of international norms. None of those functions automatically converts the resolution into a freestanding source of binding obligations for every UN member.

The Human Rights Council adopted Resolution 15/9 on September 30, 2010. It affirmed that the human right to safe drinking water and sanitation is derived from the right to an adequate standard of living and is closely related to the rights to health, life, and human dignity. The Council also reaffirmed that states bear primary responsibility for ensuring the realization of human rights. These instruments reinforced international recognition while preserving the distinction between political declarations and obligations arising under applicable legal sources (Human Rights Council, 2010).

2.3 The Separate Human Rights to Water and Sanitation

On December 17, 2015, the General Assembly adopted Resolution 70/169, recognizing the human rights to safe drinking water and sanitation as distinct but closely related rights. The resolution treated both as components of the right to an adequate standard of living, while acknowledging their different substantive requirements (United Nations General Assembly, 2015).

The distinction is important because adequate sanitation involves more than access to drinking-water supplies. Sanitation requires facilities and services that are safe, hygienic, secure, socially and culturally acceptable, and consistent with privacy and dignity. A community may have functioning drinking-water infrastructure while lacking safe sanitation. The reverse can also occur where sanitation facilities exist but drinking-water sources remain contaminated or unreliable.

Separate recognition permits more precise assessment of the obligations associated with each right. Policies that improve sanitation coverage do not necessarily resolve drinking-water shortages, while household water connections alone cannot establish that sanitation requirements have been satisfied. Both rights require attention to equality, affordability, health, and the circumstances of affected populations.

The General Assembly continued to reaffirm these rights through Resolution 80/216, adopted on December 18, 2025, by 176 votes in favor, two against, and two abstentions. The resolution reflects sustained diplomatic recognition of drinking water and sanitation within the UN human rights agenda. Its adoption did not alter the basic distinction between the non-binding character of General Assembly recognition and the binding obligations established through applicable treaties (United Nations General Assembly, 2025).

3. What Does the Right to Clean Water Guarantee?

The right to clean water concerns the conditions under which individuals obtain water necessary for personal and domestic life. Its content cannot be reduced to the existence of a water source or the installation of public infrastructure. A supply may be available but contaminated, prohibitively expensive, or located too far from the people who depend upon it.

General Comment No. 15 identifies availability, quality, and accessibility as the principal dimensions of the entitlement. Accessibility includes physical and economic access, non-discrimination, and access to relevant information. These requirements operate together. A household connection does not provide adequate protection if the water is unsafe, and a technically safe supply may be inaccessible to individuals who cannot afford to use it.

The entitlement primarily concerns drinking, food preparation, personal washing, sanitation-related personal needs, and domestic hygiene. Water required for agriculture, industry, or commercial activity engages additional legal and policy considerations. The Committee recognizes the importance of sustainable access to water for subsistence farming and adequate food, but this connection does not establish an unrestricted human rights claim over freshwater resources.

3.1 Sufficient, Safe, and Acceptable Water

Availability requires sufficient and continuous water supplies for personal and domestic uses. General Comment No. 15, paragraph 12(a), identifies drinking, personal sanitation, washing clothes, food preparation, and household hygiene as ordinary requirements. The quantity needed depends upon individual circumstances rather than a uniform amount applicable to everyone (CESCR, 2002, para. 12).

Health conditions, climate, physical activity, and working environments may affect water requirements. Individuals with particular medical needs can require additional supplies, while high temperatures may increase consumption and hygiene requirements. International human rights law does not prescribe one universal daily quantity that automatically determines compliance in every situation.

Water quality is equally important. The Committee interprets the right as requiring water free from microorganisms, chemical substances, and radiological hazards that threaten health. It also identifies acceptable color, odor, and taste as relevant characteristics. A water service that regularly delivers contaminated supplies cannot be considered adequate merely because a substantial volume reaches households.

The World Health Organization's drinking-water guidelines provide technical guidance for assessing water safety and managing contamination risks. These standards assist public authorities in designing water-quality regulations and monitoring systems. Their legal force depends upon the applicable national and international instruments; the guidelines themselves should not be confused with binding treaty provisions.

3.2 Physical Access, Affordability, and Equality

Physical accessibility requires water facilities and services to be within safe reach of the population. A distant source may impose substantial burdens on households, particularly where collection requires long journeys, prolonged waiting, or exposure to personal security risks. General Comment No. 15 also identifies access in schools, workplaces, and healthcare institutions as relevant to the enjoyment of the right.

A universal entitlement to a private household connection does not follow directly from these requirements. Different systems of provision may be compatible with human rights obligations if they deliver adequate, safe, and accessible water. The circumstances of individuals and communities remain decisive in assessing whether a particular arrangement is sufficient.

Affordability concerns the effect of water charges on the enjoyment of other protected rights. When obtaining essential supplies requires households to sacrifice adequate food, housing, or healthcare, economic accessibility becomes a serious concern. The assessment extends beyond nominal tariffs to the actual costs of obtaining water, including connection fees, transport, storage, and reliance on alternative suppliers.

Equality requires particular attention where generally available infrastructure excludes certain groups. Article 28 of the Convention on the Rights of Persons with Disabilities expressly protects equal access to clean water services. The practical realization of that guarantee may depend on accessible facilities and arrangements suited to individual needs. Formal equality of service does not necessarily produce equal opportunities to obtain water.

3.3 Does the Right to Water Guarantee Free Water?

International human rights law does not establish a universal right to unlimited free drinking water. General Comment No. 15 requires water to be affordable, but affordability does not mean that every service must be supplied without charge. Governments may adopt different financing arrangements, including tariffs, subsidies, and publicly funded provision, subject to their applicable legal obligations.

The decisive question is whether those arrangements protect essential access. Charges become problematic when their practical effect is to deny individuals sufficient water for basic personal and domestic needs. The Committee's interpretation places particular emphasis on people who lack the financial means to obtain adequate supplies.

Free or subsidized provision may be necessary in specific circumstances. Governments can adopt social tariffs, targeted assistance, or minimum free allocations to protect households experiencing serious financial hardship. The appropriate response depends on the circumstances of the affected population and the state's obligations, rather than a single international pricing formula.

The question of payment must also be distinguished from the legality of disconnecting an existing supply. A state may permit reasonable charges while remaining under duties to protect individuals against unjustified deprivation of essential water. The conditions governing disconnections, especially where people cannot pay, require a separate assessment of legal safeguards and minimum access.

4. State Obligations and the Implementation of Water Rights

The implementation of water-related human rights obligations depends principally on states. Governments establish legal standards, regulate water quality, allocate public resources, supervise service providers, and provide administrative or judicial remedies. These responsibilities continue even where the immediate delivery of water is entrusted to a local authority, public utility, or private company.

The ICESCR recognizes that achieving universal access to economic and social rights may require sustained investment. Article 2(1) obliges states parties to take steps, individually and through international assistance and cooperation, to the maximum of available resources, toward progressive realization. The provision acknowledges resource constraints but does not permit governments to postpone all action until adequate funding becomes available (ICESCR, 1966, art. 2(1)).

A proper assessment of compliance must distinguish the relevant duty from the measures chosen to satisfy it. Some obligations require immediate conduct, particularly the prohibition of discrimination and the taking of appropriate steps toward realization. Others concern the development of infrastructure and services over time. The Committee on Economic, Social and Cultural Rights has elaborated these distinctions through its interpretation of the Covenant.

4.1 The Obligations to Respect, Protect, and Fulfill

The Committee identifies three categories of responsibilities associated with the right to water: the obligations to respect, protect, and fulfill. These categories are also used in the wider interpretation of international human rights law. They help distinguish harmful state conduct from failures to regulate third parties and failures to adopt necessary positive measures.

The obligation to respect requires states to refrain from unjustified interference with existing access. General Comment No. 15, paragraph 21, addresses practices such as arbitrary disruption of water services, discriminatory restrictions, and unlawful contamination. Public authorities must also consider the effects of decisions that destroy, diminish, or obstruct established supplies. An infrastructure project, for example, may engage this obligation if government action unjustifiably deprives a community of water on which it depends.

Protection against third parties involves a different responsibility. Private businesses, agricultural operators, landlords, and water suppliers may interfere with access through contamination, excessive extraction, discriminatory practices, or inadequate service. Paragraphs 23 and 24 of General Comment No. 15 explain the Committee's position that states must take appropriate measures to prevent such interference, including effective regulation and oversight.

The obligation to fulfill requires affirmative action. Governments must take appropriate measures to facilitate and promote access, develop suitable policies, and provide assistance where individuals cannot secure essential supplies through their own means. This responsibility does not require the state to operate every water facility directly. It requires the state to meet its applicable obligations through institutions and arrangements capable of protecting the right (CESCR, 2002, paras. 20–29).

4.2 Immediate Duties, Progressive Realization, and Minimum Access

Progressive realization recognizes that extending safe water services to an entire population can require time, resources, and institutional development. It does not reduce the ICESCR to a statement of future aspirations. Article 2(1) requires steps toward realization, while Article 2(2) establishes an obligation to guarantee the exercise of Covenant rights without discrimination on the prohibited grounds.

The Committee interprets these requirements as demanding deliberate, concrete, and targeted measures. It also identifies minimum core obligations in paragraph 37 of General Comment No. 15. These include access to an essential quantity of safe water, physical access to water facilities, equitable distribution, and measures to prevent and control water-related diseases. The Committee considers these duties fundamental to the effective enjoyment of the right.

Paragraph 40 describes the core obligations identified by the Committee as non-derogable. Paragraph 41 further distinguishes a state's inability to comply from its unwillingness to use available resources. Under the Committee's approach, resource constraints do not eliminate the responsibility to demonstrate that every effort has been made to prioritize essential obligations (CESCR, 2002, paras. 37–41).

These conclusions represent the Committee's interpretation of the Covenant. The ICESCR itself does not codify the complete list of minimum core duties or establish a universally applicable numerical minimum for drinking-water provision. The concept's judicial application differs across legal systems, particularly where domestic constitutions require courts to assess the reasonableness of government measures rather than determine fixed substantive entitlements.

A related question concerns reductions in existing access. The Committee treats deliberately retrogressive measures as requiring particularly careful justification. Cuts to essential services, discriminatory reallocations, or the withdrawal of protections may raise questions concerning the use of available resources and compliance with existing obligations. A reduction in provision must be evaluated according to its effects, legal basis, and the circumstances in which it occurs.

4.3 Private Water Companies and Service Disconnections

International human rights law does not prescribe exclusive public ownership of drinking-water services. Public utilities, private operators, community arrangements, and mixed systems can all participate in provision. The relevant legal question is whether the state complies with its obligations concerning safety, accessibility, equality, and protection against harmful third-party conduct.

Where service delivery is delegated, the state retains responsibility for appropriate oversight. General Comment No. 15, paragraph 24, identifies regulation of third parties as part of the obligation to protect. Relevant measures may include water-quality requirements, transparent pricing, service standards, and safeguards against discriminatory practices. Delegation does not extinguish the state's underlying treaty responsibilities.

Service disconnections present a particularly sensitive issue. A provider may seek to discontinue supply because of unpaid charges or non-compliance with service conditions, but the effect on essential household needs cannot be disregarded. General Comment No. 15, paragraph 56, requires, under the Committee's interpretation, that interference with water access be lawful and compatible with the Covenant, accompanied by appropriate procedural protections.

The Committee identifies consultation, timely disclosure of information, reasonable notice, access to legal remedies, and legal assistance as relevant safeguards. Where disconnection is based on non-payment, the individual's capacity to pay must be considered. Paragraph 56 also states the Committee's position that an individual must never be deprived of the minimum essential level of water (CESCR, 2002, para. 56).

This does not establish an identical domestic prohibition on every disconnection in every jurisdiction. The precise enforceability of the Committee's interpretation depends on the applicable legal system. It does, however, provide an important standard for assessing whether a government has adequately protected essential access, particularly where financial hardship would otherwise result in serious deprivation.

4.4 International Assistance and Cooperation

Article 2(1) of the ICESCR expressly refers to international assistance and cooperation in the progressive realization of Covenant rights. Access to drinking water can depend on resources and technical capacities that are unequally distributed among states. International cooperation can help address these limitations through financing, infrastructure development, training, and assistance with water-quality systems.

General Comment No. 15 addresses international obligations in paragraphs 30 to 36. The Committee emphasizes cooperation concerning the right to water and the importance of avoiding conduct that interferes with its enjoyment in other countries. It also identifies assistance to developing states as relevant to fulfilling essential obligations.

Resolution 64/292 reinforces the political importance of financial assistance, capacity-building, and technology transfer. These measures may contribute to national water strategies, particularly where public institutions lack the resources required to expand safe services. The resolution does not, however, establish a universal legal formula requiring each state to provide a particular amount of funding.

International cooperation on water must also be distinguished from the law governing shared freshwater resources. Treaties concerning international watercourses may establish obligations relating to equitable and reasonable utilization, prevention of significant harm, and cooperation between states sharing a watercourse. Those rules address particular interstate relationships and cannot simply be equated with the individual entitlement to drinking water under human rights law.

5. Inequality, Water Scarcity, and Effective Access

The recognition of water as a human right has not produced universal access to safe drinking-water services. According to the WHO/UNICEF Joint Monitoring Programme, approximately 2.1 billion people lacked safely managed drinking-water services in 2024. Its 2025 report identifies substantial inequalities between populations and regions, including differences between rural and urban communities (WHO and UNICEF, 2025).

The figure requires careful interpretation. The Joint Monitoring Programme defines safely managed drinking-water services as those using an improved source located on premises, available when needed, and free from specified contamination. People who do not meet this classification may still obtain drinking water through basic, limited, or unimproved services. The figure does not mean that 2.1 billion people have no access to water whatsoever.

These statistical categories are also distinct from legal findings of human rights violations. Sustainable Development Goal 6 provides internationally agreed targets concerning water and sanitation, supported by indicators for monitoring progress. Those indicators are valuable for measuring service coverage, but they do not incorporate every legal requirement concerning affordability, equality, procedural safeguards, and state responsibility. A country may improve its national statistics while leaving particular communities without adequate protection.

Discrimination and poverty remain major obstacles to effective access. Rural households may depend on distant or unreliable sources, while residents of informal settlements can face barriers involving infrastructure, legal status, and administrative arrangements. Women and girls may bear disproportionate responsibilities for collecting household water, affecting their education, employment, safety, and opportunities for participation in public life. The Committee on Economic, Social and Cultural Rights identifies these disadvantages as relevant to the implementation of the right.

Other groups encounter particular difficulties. Persons with disabilities may be excluded by inaccessible facilities, while children face serious health risks when drinking-water supplies are contaminated. Refugees and internally displaced persons often depend upon temporary services whose continuity can be difficult to maintain. General Comment No. 15, paragraph 16, directs particular attention to groups that have traditionally experienced difficulties exercising the right, including Indigenous communities and populations affected by displacement.

The connection between water access and environmental protection is especially significant for communities dependent upon natural freshwater sources. Pollution, drought, excessive extraction, and environmental degradation can reduce both the availability and safety of drinking water. The relationship with international environmental law becomes relevant where duties concerning environmental harm, resource management, and pollution prevention operate alongside human rights obligations. These bodies of law may protect related interests, but their sources and conditions of application must be distinguished.

Climate-related pressures can aggravate existing deficiencies in water infrastructure and management. Changes in precipitation, prolonged drought, and extreme weather may disrupt supplies or increase contamination risks. The legal consequences depend on the applicable obligations and the conduct of the state concerned. The existence of environmental pressure does not automatically establish a human rights violation, but it cannot be treated as irrelevant when assessing the adequacy of measures taken to protect essential access.

Competing demands also create difficult allocation questions. Agriculture, industry, electricity generation, and domestic consumption may depend upon limited freshwater resources. General Comment No. 15 gives priority to water required for personal and domestic needs while recognizing the importance of access for subsistence farming and adequate food. Its interpretation does not resolve every dispute concerning resource allocation or establish an unlimited entitlement to water for commercial purposes (CESCR, 2002, para. 6).

Armed conflict creates additional threats to drinking-water supplies. Article 54 of Additional Protocol I to the Geneva Conventions and Article 14 of Additional Protocol II contain protections concerning objects indispensable to civilian survival, including drinking-water installations and supplies. Their prohibitions operate within the applicable rules of international humanitarian law, subject to the relevant treaty conditions. These protections are legally distinct from the ordinary human rights obligations governing access to water, although both bodies of law may be relevant during an armed conflict (Additional Protocol I, 1977, art. 54; Additional Protocol II, 1977, art. 14).

6. Judicial Protection and International Accountability

The right to water has been considered by domestic courts, regional human rights tribunals, and international supervisory institutions. Judicial proceedings have addressed water supply, affordability, contamination, resource allocation, and the failure of public authorities to protect communities dependent upon threatened sources. These decisions demonstrate that water-related claims can be legally enforceable, although the relevant standards differ between legal systems.

Some national constitutions expressly protect access to sufficient water, while other legal systems address water-related claims through rights to health, life, dignity, equality, or adequate living conditions. Courts may also apply legislation governing public utilities and environmental protection. The existence of an international human rights entitlement does not automatically confer jurisdiction upon every court or establish identical domestic remedies.

International accountability mechanisms operate under their own procedural rules. A regional court judgment, a treaty-body View, a concluding observation, and a recommendation by a United Nations Special Rapporteur have different legal characteristics. Their authority depends upon the relevant instrument and the institution issuing them. Two judicial decisions illustrate both the possibilities of enforcing water rights and the different approaches courts take to defining their content.

6.1 Lhaka Honhat v. Argentina: Water and Indigenous Rights

The Inter-American Court of Human Rights delivered its judgment in Indigenous Communities of the Lhaka Honhat (Our Land) Association v. Argentina, Series C No. 400, on February 6, 2020. The proceedings concerned Indigenous communities in Argentina's Salta Province whose traditional territory and natural resources had been affected by activities including livestock grazing, illegal logging, and fencing. The dispute also involved the recognition of communal property and the communities' participation in decisions affecting their lands.

The Court found Argentina internationally responsible for violations involving Indigenous communal property and rights associated with a healthy environment, adequate food, water, and cultural identity. Its analysis recognized the close relationship between the communities' traditional territory and the resources necessary for their physical and cultural survival. Environmental degradation had consequences extending beyond property interests alone (Inter-American Court of Human Rights, 2020).

The judgment was particularly significant because the Court examined the rights to a healthy environment, adequate food, water, and cultural identity autonomously under Article 26 of the American Convention on Human Rights. In its discussion of water, particularly paragraphs 222 to 230, the Court drew upon international human rights instruments and the interpretation developed in General Comment No. 15. It identified duties concerning non-discrimination, protection against third-party interference, and essential access for individuals unable to obtain water through their own means.

The Court's approach was not unanimous. Judge Eduardo Vio Grossi dissented from the majority's interpretation of Article 26 as permitting the autonomous judicial enforcement of these rights. His objection concerned the Court's jurisdictional and interpretive basis for declaring violations under Article 26, rather than a denial that access to water deserved human rights protection. The disagreement illustrates an important distinction between recognizing a substantive entitlement and determining whether a particular tribunal has authority to adjudicate its violation.

The judgment required Argentina to adopt remedial measures addressing the communities' rights and the deterioration of their resources. These included identifying critical situations involving inadequate access to drinking water or food, preparing an action plan, protecting water resources against contamination, and guaranteeing permanent access to drinking water. The Court retained responsibility for supervising compliance. The existence of these orders should not be confused with proof that every measure has been completed (Inter-American Court of Human Rights, 2020, paras. 332–335).

Lhaka Honhat demonstrates how a regional human rights court can examine water access as an autonomous protected right within its treaty system. Its reasoning is important for understanding the relationship between environmental harm, Indigenous rights, and access to essential resources. The judgment binds Argentina in the proceedings, while its interpretation contributes to Inter-American jurisprudence without establishing a universally binding rule for every international or domestic court.

6.2 Mazibuko v. Johannesburg: Water and Judicial Review

A different approach appears in Mazibuko and Others v. City of Johannesburg and Others [2009] ZACC 28, decided by the South African Constitutional Court on October 8, 2009. The case concerned Section 27 of the South African Constitution, which recognizes everyone's right of access to sufficient water and requires the state to take reasonable legislative and other measures, within available resources, to achieve progressive realization.

The applicants challenged Johannesburg's policy of providing six kiloliters of free basic water per household each month and the installation of prepaid water meters in Phiri, Soweto. They argued that the allocation was insufficient and that the metering arrangements were unlawful. The dispute raised questions about how courts should assess the adequacy of government water policies and whether constitutional guarantees required a particular minimum quantity.

The High Court ruled in favor of the applicants and ordered the provision of 50 liters of free water per person per day. On appeal, the Supreme Court of Appeal determined that 42 liters per person per day constituted sufficient water under Section 27(1), subject to the qualifications in its order. It also found the prepaid-meter arrangements unlawful, although it suspended the relevant declaration to permit the City to address the legal position.

The Constitutional Court rejected the approach of prescribing a fixed constitutional quantity. It held that Sections 27(1)(b) and 27(2) must be read together and that the state's positive obligation concerned reasonable measures toward progressive realization within available resources. The Court found Johannesburg's free-basic-water policy reasonable in the circumstances and upheld the legality of the prepaid-meter arrangements, setting aside the lower courts' orders (Constitutional Court of South Africa, 2009, paras. 49–68, 169).

The Court emphasized the importance of government policy review and the institutional responsibilities of public authorities. It did not hold that access to sufficient water was unenforceable or that the government could disregard constitutional obligations. Its reasoning concerned the form of judicial supervision appropriate to a constitutional guarantee requiring reasonable measures over time.

The contrast with the minimum core approach in General Comment No. 15 is significant but must be understood carefully. The Committee interprets the ICESCR, while Mazibuko concerned the South African Constitution and domestic water legislation. The Constitutional Court's refusal to define a fixed quantity illustrates a particular approach to judicial enforcement; it does not determine the binding status of the Committee's interpretation under international law.

6.3 United Nations Monitoring and Individual Complaints

The Committee on Economic, Social and Cultural Rights supervises implementation of the ICESCR through reporting and other procedures established under the relevant instruments. States parties submit periodic reports describing measures taken to fulfill Covenant obligations. The Committee examines those reports and issues concluding observations addressing progress, deficiencies, and recommended action. Water-related concerns may arise through the rights to health, adequate living standards, and non-discrimination.

The United Nations Special Rapporteur on the human rights to safe drinking water and sanitation provides another mechanism of international scrutiny. The mandate was established by the Human Rights Council in 2008 and subsequently developed into its present form. Its functions include thematic reporting, country visits, communications concerning alleged violations, and recommendations concerning implementation. These activities can draw attention to serious deficiencies, but the Special Rapporteur does not exercise the jurisdiction of an international court.

An individual complaints mechanism also exists under the Optional Protocol to the ICESCR, which entered into force on May 5, 2013. The procedure applies only where the state concerned has accepted the Protocol and the relevant admissibility requirements are satisfied. These ordinarily include exhaustion of available domestic remedies, subject to the exceptions recognized by the Protocol. The Committee may examine alleged violations and adopt Views setting out its conclusions and recommendations (Optional Protocol to the ICESCR, 2008, arts. 2–9).

The legal character of those Views must be distinguished from a binding judgment delivered by an international court. They constitute authoritative determinations by the treaty body under the communications procedure, but their implementation depends upon the applicable international and domestic arrangements. The existence of a favorable finding does not itself ensure that water services will be restored or that compensation will be provided.

Domestic remedies remain particularly important. Courts, regulatory authorities, ombuds institutions, and national human rights bodies may provide avenues for challenging unlawful conduct or failures to protect essential access. General Comment No. 15, paragraphs 55 to 59, emphasizes remedies and procedural protection, including the importance of judicial consideration of water-related claims. Effective accountability requires both a legally recognized entitlement and institutions capable of responding when it is violated.

Conclusion

Clean drinking water is recognized as a human right under international human rights law. Its principal universal treaty foundation lies in the International Covenant on Economic, Social and Cultural Rights, particularly Articles 11 and 12, as interpreted by the Committee on Economic, Social and Cultural Rights. Specialized human rights conventions provide additional express guarantees. General Assembly Resolution 64/292 strengthened international recognition in 2010, but did not independently create a new binding treaty obligation.

The substantive entitlement concerns sufficient, safe, acceptable, physically accessible, and affordable water for essential personal and domestic use. It does not establish unlimited free provision or a single universal system of water ownership and distribution. States must comply with applicable duties concerning non-discrimination, protection against unjustified interference, regulation of third parties, and appropriate measures toward realization. The Committee's interpretation of minimum essential access provides an influential standard, while its precise judicial application depends on the governing legal framework.

Judicial decisions demonstrate that recognition and enforcement are distinct questions. The Inter-American Court's judgment in Lhaka Honhat recognized water as an autonomously enforceable right within its interpretation of Article 26 of the American Convention. South Africa's Constitutional Court in Mazibuko approached access to sufficient water through the constitutional requirement of reasonable measures and progressive realization. Neither decision establishes an identical test for every legal system.

The continuing lack of safely managed drinking-water services for billions of people illustrates the distance between international recognition and practical enjoyment. That distance does not diminish the legal status of the right. It identifies the circumstances in which applicable state obligations must be implemented, assessed, and enforced. The right to water establishes legal responsibilities, but their fulfillment ultimately depends upon effective institutions, equitable access, protection of essential supplies, and remedies capable of addressing violations.
