LA SIERRITA is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, formerly serving 2,039 people from groundwater.
EPA's federal records list this system as inactive in 2009; the record below is historical.
As of August 1, 2026, its federal record holds 2 entries between 1999 and 2005, all of which EPA lists as closed. Nothing has been added since 2005.
