The town of San Pedro, gateway to the Province of Laguna, holds the unique distinction of being the site of the first Liberty Well in the Philippines. The well was constructed in San Vicente in 1954 under our beloved President Magsaysay's Liberty Well Program, which aimed to supply potable water to all Filipinos. That the town was chosen as the site of the first Liberty Well was not purely coincidental. Call it 'gut feel' but President Magsaysay, being an engineer, knew then that San Pedro, being the basin of Laguna de Bay, could be one of the best, if not the best, underground water sources in Laguna. Presumably, he wanted the first Liberty Well to last for a long, long time. History proved him right. Up to now, Liberty is still in operation. It was re-activated by San Pedro Water District two or three years ago, and is now one of its principal water sources.

The present water supply system of San Pedro, Laguna, which includes the Liberty Well, was constructed by the provincial Government in 1961. It was later turned over to the now defunct NAWASA and with the abolition of all provincial and municipal facilities of NAWASA, the system was ceded to the municipal government of San Pedro.

Subsequently, the town's water system was donated to the SPWD by virtue of the same resolution, in accordance with the provisions of Presidential Decree No. 198, as amended.
