Local Government Share in National Wealth: Water Rights and Resource Utilization

The Supreme Court recently clarified a significant question in local governance and natural resource law: when does a local government unit (LGU) become entitled to a share in the proceeds from the utilization and development of national wealth? In Metropolitan Waterworks and Sewerage System v. Provincial Government of Bulacan (G.R. No. 185184, October 3, 2023), the Court ruled on whether the Province of Bulacan could claim a share from the Metropolitan Waterworks and Sewerage System (MWSS) for the use of water from Angat Dam. The decision provides crucial guidance on the distinction between natural resources and appropriated water, and on the limits of an LGU's share in national wealth.

The Constitutional and Statutory Framework

The 1987 Constitution guarantees LGUs an equitable share in the proceeds of the utilization and development of national wealth within their respective areas. Section 7, Article X provides that local governments "shall be entitled to an equitable share in the proceeds of the utilization and development of the national wealth within their respective areas, in the manner provided by law."

This constitutional mandate is implemented through the Local Government Code of 1991 (Republic Act No. 7160), particularly Sections 289, 291, and 292. Under these provisions, LGUs are entitled to a share from the development and utilization of national wealth located within their territorial jurisdiction.

The Case: Bulacan's Claim Against MWSS

The Province of Bulacan filed a complaint against MWSS for specific performance and payment of its national wealth share. The province argued that Angat Dam, located within its territory, is the primary source of water for Metro Manila. It claimed that MWSS derived proceeds from the water resource and should therefore pay Bulacan a share under the Constitution and the Local Government Code.

The trial court ruled in favor of Bulacan, and the Court of Appeals affirmed with modification. Both lower courts held that water is a natural resource, that a substantial portion of the water in Angat Dam is sourced from Bulacan, and that MWSS is engaged in the utilization and development of national wealth.

The Supreme Court's Ruling

The Supreme Court reversed the lower courts' decisions. The Court held that the requisites for an LGU's entitlement to a share in national wealth were not established in this case.

Dam water is appropriated water. The Court explained that while water is undoubtedly a natural resource, it ceases to be so once it is taken or diverted from its natural source. Under Presidential Decree No. 1067 (The Water Code of the Philippines), the appropriation of water refers to the acquisition of rights over the use of waters or the taking or diverting of waters from natural resources. Once water from the Angat River is impounded into the Angat Dam, it becomes appropriated water and no longer forms part of the State's natural resources.

MWSS is not engaged in utilization and development of national wealth. The Court examined MWSS's charter and found that the agency was created for regulatory functions—to operate and maintain waterworks systems for supplying potable water to the public. MWSS does not derive profit from the water in Angat Dam in a manner that would trigger an LGU's share. As the Court noted, "to give respondent a share in the proceeds from the utilization and development of dam water is illogical because petitioner does not derive proceeds by the mere operation of the dam."

The tax is imposed at the point of extraction. The Court observed that the National Power Corporation (NPC), which previously managed the Angat Hydro Electric Power Plant, had been paying the national wealth tax to Bulacan prior to the plant's privatization in 2014. This confirms that the tax is properly imposed upon the extraction of water from its natural source—the Angat River—not upon the use of already-appropriated dam water.

Practical Takeaways

• LGUs should identify the exact point of extraction. An LGU's share in national wealth applies to natural resources found within its territory. Once a resource—such as water—is extracted or diverted from its natural source, it becomes appropriated and may no longer be subject to the national wealth share.

• Not all government agencies are liable. The mere operation of infrastructure like dams does not automatically constitute "utilization and development of national wealth." The agency must be deriving proceeds from the natural resource itself, not merely performing regulatory or public service functions.

• The distinction between natural source and artificial structure matters. Water flowing in a river is a natural resource; water stored in a dam is appropriated water. This distinction determines whether an LGU can claim a share.

• Review existing arrangements. LGUs that have been receiving national wealth shares should verify that the payments are properly based on the extraction of natural resources, not on the use of appropriated water, to avoid potential disputes or refund claims.

• The ruling aligns with prior jurisprudence. The Court applied its earlier ruling in IDEALS, Inc. v. PSALM, which similarly held that power generation using water already impounded in Angat Dam does not involve the utilization and development of national wealth.
