GUAMANI Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of August 31, 2015. It is no longer an operating public water system under this PWSID, and no compliance deadlines — including the 2027 Consumer Confidence Report rule — apply to it.

If you are a resident looking for your current water provider, see water systems in Guayama Municipio County, PR.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Puerto Rico’s official records. Always confirm current status with Puerto Rico before making decisions based on this information.

System facts

System ID (PWSID): PR0004755
System type: Community Water System
Population served: 1,056
Service connections: 264
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

GUAMANI is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 1,056 people from surface water.

EPA's federal records list this system as inactive in 2015; the record below is historical.

As of August 1, 2026, its federal record holds 74 entries between 1980 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.

Of the 74, 41 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Surface Water Treatment Rules, volatile organic chemicals, and synthetic organic chemicals.
