Source of Water in Vietnam,

The Vietnam community in Guaynabo receives tap water from the Puerto Rico Aqueduct and Sewer Authority (PRASA) through the metropolitan water system. Its main source is surface water from the Río Grande de Loíza and Carraízo Reservoir.

This water is treated at regional facilities, including the Sergio Cuevas Water Filtration Plant in Trujillo Alto, before entering the distribution network. PRASA may also blend water from interconnected sources depending on system operations.

Vietnam Drinking Fountains

Public drinking fountains in Guaynabo are generally safe when connected to the treated municipal water supply and properly maintained. Puerto Rico’s public water systems are regulated under U.S. drinking-water standards.

Fountain safety can be affected by poor cleaning, damaged fixtures, or temporary water advisories. Use fountains that are clean and functioning properly, and avoid any marked with a boil-water notice.
