MARICAO Water System

Inactive system

This water system is marked inactive in EPA’s federal records as of February 6, 2001. 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 Vega Alta 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): PR0005577
System type: Community Water System
Population served: 4,572
Service connections: 1,143
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

MARICAO is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, formerly serving 4,572 people from surface water.

EPA's federal records list this system as inactive in 2001; the record below is historical.

As of August 1, 2026, its federal record holds 60 entries between 1980 and 2000, all of which EPA lists as closed. Nothing has been added since 2000.

Of the 60, 28 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 Total Coliform Rules, volatile organic chemicals, and inorganic chemicals.
