The Puerto Rico Aqueducts and Sewers Authority (PRASA; Spanish: Autoridad de Acueductos y Alcantarillados de Puerto Rico) is a water company and the government-owned corporation responsible for water quality, management, and supply in Puerto Rico, a US insular area.

[1] PRASA is the only entity authorized to conduct such business in Puerto Rico, effectively making it a government monopoly.

[3] The aftermath of Hurricane Maria left most of the island without water service for weeks.

The agency announced in December, three months after the storm had passed, that the water service was restored to 90% of its clients.

[4] The authority was ordered by then governor Ricardo Rosselló to not charge for the service it was unable to provide during this period.
