OSSE –San Juan

What OSSE –San Juan does

OSSE (Obras Sanitarias Sociedad del Estado) is the provincial state-owned water and sewage utility of the Government of San Juan Province, Argentina, legally constituted in its current form on 26 February 1982 under Law No. 4991 when national Obras Sanitarias de la Nación transferred provincial operations. It is the sole authorized provider (Ente Rector) of potable water and sanitation services across all 19 departments of the province, serving 785,782 registered water users (covering 98.5% of provincial population) and 596,724 sewage users (covering 74.8%). Its operational footprint includes 19 potabilization plants, 116 autonomous boreholes across 66 community systems, and 13 wastewater treatment plants, all supervised by a SCADA-based real-time monitoring and control system tracking pump status, chlorine levels, turbidity, tank levels, pressure, and flow rates, with fiber optic sensor networks along major aqueducts.

The utility runs a hybrid revenue model anchored by recurring cadastrally-billed monthly tariffs for residential and commercial water and sewage service (with property-based assessment considering land area, covered area, building type, and use/destination; differentiated plans exist for retirees/pensioners and the Plan RED for the unemployed), supplemented by connection fees, certificate issuance, water-quality analysis services, and large infrastructure contract execution. Active mega-projects include the Acueducto Gran Tulum (ARS 7,609,557,133 contract; first deployment in Argentina of large-diameter stainless steel piping at 1200–1600mm using K-TIG/GTAW keyhole welding with phased-array ultrasonic testing) and the Ampliación del Subsistema Cloacal Rawson y PTLC Cerrillo Barboza (ARS 3,851,436,121 contract), financed by ENOHSA and FONDEAR (backed by Inter-American Development Bank and CAF) national infrastructure funds. Operational technology includes a domestically developed SMS-based sewage pumping station monitoring system (claimed to be 90% cheaper than conventional SCADA), and energy-efficient facultative-lagoon (Lagunas Facultativas) treatment at the Cerrillo Barboza plant.

OSSE is wholly owned by the Gobierno de la Provincia de San Juan with no private equity, no venture capital, no disclosed subsidiaries, and no publicly traded instruments. Under President Ing. José Luis Beltrán (in office since December 2023), alongside Gerente General Carlos Orrego and a senior team including heads of Operations and Technical Planning, the organization employs over 600 collaborators. Customer access is direct-to-consumer via Casa Central headquarters in the capital, commercial offices in each of the 19 departments, the facturaweb.osse.com.ar self-service portal, three dedicated WhatsApp channels, a toll-free hotline (0800-222-6773), and an extensive payment network (Red Link, Red Banelco, Banco San Juan, San Juan Pagos, Rapipago, Pago Fácil, Correo Argentino). Recent service-area extensions include first-time sewage systems in Zonda (6,200 residents) and Ullum (6,300 residents), and an active transfer agreement incorporating the Unión Vecinal San Roque distribution system in Jáchal into OSSE's direct operation.
