Public Waters and Public Dominion
Public waters are treated as property devoted to public use and public service, not as ordinary objects of private ownership. Rivers, natural beds, waters flowing in natural channels, lakes and lagoons on public land, rain waters running through public ravines or beds, subterranean waters on public land, and waters that have left private land fall within the public-law treatment of water resources.
The practical consequence is that the water resource itself remains under State control. A private person may acquire a legally protected right to use water, but that right is not ownership of the water in its natural source. The holder receives a privilege of appropriation and beneficial use, subject to the terms of the grant, rights of third persons, and the State's continuing police power over conservation, public health, public safety, navigation, flood control, and equitable distribution.
Public dominion also explains why occupation, fencing, enclosure, or long physical use of a river, stream, lake, canal, spring, or watercourse does not by itself make the water private. Even where the Civil Code recognizes acquisition of the use of public waters by prescription, the acquired interest is a use right, not a transfer of public ownership.
Civil Code Rule on Use of Public Waters
Articles 504 to 506 of the Civil Code provide the older civil-law framework for the use of public waters. The use of public waters may be acquired by administrative concession or by prescription for ten years, but the extent of the rights and obligations arising from such use is governed by special laws and regulations.
The special-law clause is controlling. Water is a regulated natural resource, so the Civil Code rule must now be read together with the Water Code. The modern operative form of administrative concession is the water right evidenced by a water permit, except for limited uses that the Water Code allows without a permit.
The Civil Code's reference to prescription should be read narrowly. It cannot be used to claim ownership of public waters, defeat the public character of a water resource, or avoid regulatory requirements imposed by the Water Code. At most, it recognizes that a continuous, adverse, and legally cognizable use may have civil effects when compatible with special law and with State control over water resources.
Every concession for the use of waters is understood to be without prejudice to third persons. A permit or concession does not settle private boundary disputes, authorize trespass on private land, eliminate liability for damage caused by diversion or obstruction, or destroy existing lawful rights of other users. It grants only the water-use privilege that the State is competent to grant.
The Civil Code also provides that the right to make use of public waters is extinguished by the lapse of the concession and by non-user for five years. This reflects the rule that a water-use right is functional. It exists for beneficial use and may be lost when the authority expires or when the holder abandons the use in a legally significant way.
Water Right and Water Permit
Under the Water Code, no person, including a government instrumentality or a government-owned or controlled corporation, may appropriate water without a water right, unless the use falls within a statutory exception. The water right is evidenced by a water permit issued through the administrative system for water resources.
Appropriation means taking or using water from a natural source for a beneficial purpose. The right is measured by the authorized purpose, quantity, source, point of diversion or withdrawal, place of use, manner of use, and other conditions imposed by the permit. A water permit is therefore specific, regulated, and conditional.
The water permit does not give the holder a roving entitlement to use all waters connected with the source. It authorizes only the approved appropriation. A user permitted to divert water for irrigation may not automatically apply the same water to an industrial, commercial, municipal, or recreational use without the required approval, because purpose is part of the legal identity of the water right.
Beneficial use is the measure and limit of the right. A claimed need unsupported by actual useful application does not justify indefinite control over a public resource. Conversely, a permitted use must be exercised in a manner consistent with conservation, reasonable efficiency, and the rights of other lawful users.
Uses of Water and the Need for a Permit
The Water Code recognizes different purposes for which water may be appropriated, including domestic, municipal, irrigation, power generation, fisheries, livestock raising, industrial, recreational, and other beneficial uses. These categories matter because the permitted purpose determines the scope of the right and the public interests considered in the administrative evaluation.
| Use or act | Legal treatment | Reason |
|---|---|---|
| Taking water by hand-carried receptacles | No water permit is required. | The use is small, direct, non-exclusive, and incidental to ordinary public use. |
| Bathing, washing, watering or dipping domestic or farm animals | No water permit is required, subject to regulation. | The activity does not ordinarily involve appropriation by works, diversion, or exclusive control. |
| Navigation of watercraft and flotation of logs or other objects | No water permit is required for the use of the natural body of water. | The activity is a public-use incident of navigable or usable waters, not a consumptive appropriation. |
| Pumping, diverting, impounding, or distributing water for a continuing beneficial use | A water permit is generally required. | The user is appropriating a portion of the public resource and may affect quantity, flow, access, and other users. |
| Use by a government agency or government-owned or controlled corporation | A water permit is still required unless an exception applies. | Public character of the user does not dispense with State allocation and regulation of water resources. |
The permit-exempt uses are not absolute. They remain subject to control, protection, conservation, sanitation, public order, navigation, and other lawful regulation. An exempt act does not authorize pollution, nuisance, obstruction of a watercourse, construction of works, permanent occupation of the bed or banks, or exclusion of other lawful users.
The distinction between domestic need and permit-exempt use is important. A person who merely fills hand-carried containers from a natural source does not need a water permit for that act. A person who installs a pump, pipe system, reservoir, or diversion works for continuing household, subdivision, farm, commercial, or institutional supply is ordinarily appropriating water and must proceed through the permit system.
Who May Apply for a Water Permit
Only Filipino citizens of legal age and juridical persons duly qualified by law to exploit and develop water resources may apply for water permits. The requirement connects water allocation with the constitutional and statutory treatment of natural resources as matters of national patrimony and public regulation.
For natural persons, citizenship and legal capacity are basic qualifications. For juridical persons, qualification depends on compliance with nationality, capacity, franchise, utility, corporate-purpose, and sector-specific requirements applicable to the proposed water use. A corporation may be organized under Philippine law and still be unqualified for a particular water-related undertaking if another law imposes additional restrictions.
Qualification to apply is not the same as entitlement to receive a permit. The applicant must still show availability of water, a beneficial purpose, legal access to the place of use or diversion works, consistency with existing rights, and absence of unacceptable adverse effects.
Application, Notice, and Administrative Evaluation
A person who desires to obtain a water permit files an application with the proper water resources authority, historically the National Water Resources Council and now administered through the National Water Resources Board system. The application is made public so that interested persons may oppose or protest the proposed appropriation.
Publication and protest are essential because water use is relational. A proposed diversion upstream may reduce downstream supply, alter natural flow, affect irrigation, impair fisheries, interfere with navigation, increase flooding, degrade water quality, or burden lands needed for works. The proceeding is therefore not a purely private transaction between the applicant and the State.
In deciding whether to grant the permit, the authority considers protests, prior permits, availability of water, the amount of water needed for the proposed beneficial use, possible adverse effects, land-use economics, and other relevant factors. The inquiry is administrative, technical, and public-interest oriented.
Prior permits matter because water already lawfully allocated cannot be ignored. Availability of water requires attention to source capacity, seasonal variation, existing uses, ecological and public needs, and the reliability of the proposed withdrawal. The requested quantity must be tied to the beneficial purpose, because excessive allocation invites hoarding and inefficient use of a public resource.
Possible adverse effects include injury to existing users, depletion of supply, deterioration of water quality, changes in drainage or flooding, public health risks, damage to land or improvements, and conflicts with community or environmental needs. Land-use economics concerns whether the proposed use is reasonable in light of the location, surrounding uses, development plans, and the social value of competing demands.
Effect of a Granted Permit
When the application is approved, the permit is issued and recorded. Recording gives public notice of the existence and terms of the water right, but it does not convert the permit into private ownership of the source. The holder remains bound by the approved purpose, quantity, source, place, period, conditions, and applicable regulations.
A permit holder may protect the granted use against unlawful interference, but the protection extends only to the legal water right. The holder cannot prevent ordinary permit-exempt uses, cannot disregard superior or prior lawful rights, and cannot insist on a volume of water that is unavailable because of lawful regulation, shortage, or public necessity.
A water permit may require separate property rights or legal authority over land where intake structures, canals, pipes, reservoirs, or other works will be installed. The permit does not itself create ownership of private land, an easement over another's estate, or a right to enter and construct works without consent, expropriation, or other lawful basis.
Because every concession is without prejudice to third persons, civil liability may still arise from negligent construction, unreasonable diversion, flooding, contamination, erosion, deprivation of lawful supply, or violation of property rights. Compliance with the permit is important, but it is not a blanket defense to all private and public consequences of harmful water use.
Relationship Between Public Use and Private Interests
Public waters may pass through or beside private land, but the private character of the land does not make the flowing public water private. The landowner's rights over the soil must be reconciled with the public character of the water, lawful uses by others, natural drainage, and regulatory authority over water resources.
A riparian or adjacent owner may have practical access to the water, but proximity is not equivalent to an exclusive water right. Continuous use by the landowner may support a claim only within the limits of law, and the use remains subject to permit requirements when it amounts to appropriation under the Water Code.
Private rights are also protected from uncompensated invasion. A water permit granted to one person does not allow that person to occupy another's land, destroy improvements, or impose a burden beyond what lawfully established easements, agreements, permits, or expropriation proceedings allow. Public dominion over water should not be confused with public ownership of all lands affected by water works.
Loss, Limitation, and Regulation of Use
The right to use public waters may end by expiration of the concession or permit, by legally significant non-use, by violation of permit conditions, by abandonment, or by operation of special water regulations. The Civil Code's five-year non-user rule expresses the broader principle that water rights are preserved by actual beneficial use, not by paper claims detached from need.
Regulation may also limit an existing use without extinguishing it. Shortage, drought, public health emergencies, competing municipal needs, environmental protection, flood control, or conservation measures may justify restrictions on timing, quantity, manner of diversion, or priority of use. Since the water remains a public resource, individual use is always conditioned by the common interest.
The governing idea is allocation rather than alienation. Public waters are not sold into private ownership; they are administered so that beneficial uses may be recognized, harmful uses may be controlled, and competing demands may be harmonized under law.
