The U.S. Geological Survey estimates annual public-supply water withdrawn from freshwater sources in Puerto Rico using data obtained from various agencies on the island, including the Puerto Rico Aqueduct and Sewer Authority (PRASA), and the Puerto Rico Department of Health (PRDOH). Public-supply withdrawals from surface and groundwater sources are tabulated by municipality, and by PRASA water service area or public water supply system. When supporting information is available, the USGS also tabulates annual domestic water use for users supplied by public systems such as PRASA and non-PRASA community water systems which are certified by PRDOH. Domestic water use includes indoor and outdoor uses at residences. Version 2.0 Estimated public-supply water withdrawals in Puerto Rico for the years 2017–20 have been published. This data release consists of Microsoft Excel workbooks related to a cooperative project between the U.S. Geological Survey (USGS) and the Puerto Rico Aqueduct and Sewer Authority (PRASA) to estimate public-supply water withdrawals for the years 2017–20. The total annual volume withdrawn from PRASA and non-PRASA public-supply wells and surface-water intakes was aggregated by municipality and PRASA public water system identification (PWSID) to obtain total surface-water and groundwater withdrawals for PRASA and non-PRASA systems.
