Term Wastewater
Definition

Water that has been contaminated from use. Depending on its origin, it is defined as liquid waste (or waste-carrying water) from households, public and private institutions or industrial and commercial establishments, all of which may be combined with groundwater, surface water, or rain water.

 Water treatment plants are used to decrease the amount of chemical, physical, and biological residue in waste water in order to purify it. The institutions in charge of wastewater in the country are: Instituto Nacional de Agua Potable (INAPA) and the regional drinking water and sewage corporations: Corporación de Acueducto y Alcantarillado de Santo Domingo (CAASD); Corporación de Acueducto y Alcantarillado de Santiago (CORAASAN); Corporación de Acueducto y Alcantarillado de Puerto Plata (CORAAPLATA); Corporación de Acueducto y Alcantarillado de La Romana (CORAAROMANA), and Corporación de Acueducto y Alcantarillado de Moca (CORAAMOCA).

In the Dominican Republic, only 20.1% of the population is connected to a sewer system; 69.42% has an on-site sanitation system, such as a septic tank in urban areas or a latrine in rural areas, and 10.48% are located within what are known as areas of open defecation, mainly in ravines. Of the total amount of water channeled through the sewer system, only 48.5% is treated at water treatment plants.
