What Corporación del Acueducto y Alcantarillado de Santiago does

Corporación del Acueducto y Alcantarillado de Santiago (CORAASAN) is a Dominican government-owned autonomous public utility corporation established by Law No. 582 of 1977 and modified by Law No. 328-98 of 1998, operating under direct dependency on the Executive Power. It holds exclusive statutory authority to provide potable water supply and sanitary sewerage services across all municipalities of Santiago province, including Santiago, Licey, Tamboril, and Moca, serving over 700,000 inhabitants with a treatment and distribution capacity of 134 MGD and a wastewater treatment capacity exceeding 35 MGD through a 1,100 km sewer network feeding the Rafey, Cienfuegos, and Tamboril treatment plants.

CORAASAN's operational backbone combines physical infrastructure (the Acueducto Cibao Central with intake from the Bao dam and López reservoir, plus newer additions such as the La Canela aqueduct inaugurated in November 2020 and the Cienfuegos plant in August 2021) with a GPS-based georeferenced asset management system covering over 80% of pipelines and 100% of pumping stations and storage tanks. The institution operates ISO 9001:2015 certified laboratories (recertified in 2021) providing internal and external physicochemical and microbiological analysis, and supports planning with drone-based aerial surveys and Lidar elevation modeling. Digital service channels include a Virtual Office portal, mobile application, IVR system, call center, and authorized collection agency network.

The business model is a regulated utility model with three revenue streams: recurring residential, commercial, and industrial water supply and sewage service fees (with tiered domestic rates from RD$1,157 to RD$2,957 for connection plus monthly consumption-based billing); external potable water analysis services priced at RD$200-RD$1,300 per determination; and external wastewater analysis services at RD$276-RD$2,805. Customer segments are primarily residential, with secondary commercial, industrial, municipal government, and educational institution segments. The institution is led by Director General Ing. Andrés Corsinio Cueto Rosario (appointed via Decreto 48-25) and executes a public Strategic Plan 2021-2024 framework that prioritizes infrastructure expansion, service coverage extension, and operational transparency through its public portal.
