The water supply system of the Municipality of Pozorrubio was established in 1962 by the National Waterworks and Sewerage Authority (NAWASA). The physical structures of the system comprised of a concrete water tower, one deep well and distribution mains, all located within the Poblacion. In 1966, the operation of the system was turned over to the Municipality.
The development strategy under the Presidential Decree No. 198 has reached Pozorrubio in 1980 when the Local Government of Pozorrubio passed a resolution organizing and forming a water district in the Municipality. The municipal authorities transferred the operation and management including all the waterworks and facilities to the newly created entity. On September 24, 1980, the Local Water Utilities Administration issued Certificate of Conditional Conformance No. 133 to the new entity named Pozorrubio Water District.
POWAD is a local corporate entity established on a local option basis to operate a water supply system in one or more provincial cities or municipalities. It is governed by a Board of Directors through a General Manager. POWAD operates as a government-owned and controlled corporation (GOCC).
POWAD is a self-supporting agency with no financial subsidy from the national government. The District generates its funds and revenues from the collection of water bills, application fees, penalty charges imposed on late payments, interest on deposits, and through the sale of construction materials.
