RUCIO Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of January 4, 2010. 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 Penuelas 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): PR0004284
System type: Community Water System
Population served: 328
Service connections: 82
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

RUCIO is one of 449 community water systems in Puerto Rico in the 500 or fewer people size category, formerly serving 328 people from surface water.

EPA's federal records list this system as inactive in 2010; the record below is historical.

As of August 1, 2026, its federal record holds 53 entries between 1983 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.

Of the 53, 42 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 synthetic organic chemicals, the Total Coliform Rules, and inorganic chemicals.
