Obras Sanitarias MGP

What Obras Sanitarias MGP does

Obras Sanitarias MGP (operating as OSSE, legal name Obras Sanitarias S.E. MGP) is a state-owned water and sanitation utility serving the Partido de General Pueyrredon district, including Mar del Plata and Batán in Buenos Aires Province, Argentina. The company holds a regulated monopoly franchise over potable water production, sewerage collection and treatment, and stormwater drainage within this territory, operating infrastructure that includes the Planta Ing. Baltar water treatment plant, the Emisario Submarino (submarine outfall), and the historic Torre Tanque — a National Historical Monument functioning as both a 13.5 million-liter cistern plus 500,000 liter elevated tank and a public tourist attraction. Service operations are supported by a 222-vehicle fleet, a meteorological radar system, a water quality laboratory, and hydrogeological well-drilling capabilities.

OSSE generates revenue through three primary streams: monthly recurring utility billing to residential and commercial customers (frentistas), one-time connection and network extension fees, and government infrastructure funding. The company's distribution model is direct-to-consumer with no intermediaries, combining a digital self-service channel (Oficina Virtual), physical customer service offices, self-service terminals, and field operations. In 2026, OSSE introduced PROGERAC, a program enabling residents to directly finance and contract network extension works, alongside a $108.6M tender for the El Martillo network completion project, $149M+ in Parque Luro/Las Heras sewage works, and a fleet expansion of 22 new zero-kilometer vehicles.

Beyond core utility operations, OSSE operates community-facing programs including the EcoOSSE environmental education initiative and the annual Aquatón competition (currently in its 17th edition, reaching 1,500+ students). The company is governed by a leadership team headed by President Tomás Amato, with no private equity, venture capital, or institutional ownership — it operates entirely as a Sociedad del Estado under the Municipality of General Pueyrredon.

Broad incumbents

• American Water Works Company: Largest publicly traded US water and wastewater utility. Comparable as a regulated water/wastewater utility serving residential and commercial customers under franchise-style arrangements.
• Veolia Water Technologies & Solutions: Global water and wastewater services major. While not a direct municipal peer, Veolia overlaps with OSSE's water treatment operations and represents the broader incumbent landscape for water utility operations and EPC.
• Suez Water Technologies & Solutions: Global water treatment and services operator. Comparable at the category level (water/wastewater treatment), though operating at vastly different scale and with private-operator rather than state-utility model.
• ACCIONA Agua: International water infrastructure operator active in treatment plant construction and operation. Comparable at the engineering and O&M layer that OSSE performs in-house through Planta Ing. Baltar and its laboratory.

Direct peers

• SABESP (Companhia de Saneamento Básico do Estado de São Paulo): Brazil's largest state-level water and wastewater company, listed on B3. Comparable in core activity (water production, distribution, sewerage collection/treatment) and in operating as a publicly controlled regional water utility.
• Aguas Cordobesas: Concessionaire providing water and sewerage services in the city of Córdoba. Directly comparable in business model (regulated water distribution) and Argentine operating context to OSSE.
• AySA (Agua y Saneamientos Argentinos): Argentina's largest water and sewerage concessionaire, serving the Buenos Aires metropolitan area. Both AySA and OSSE operate as regulated water/sewerage utilities with a similar mix of distribution, treatment, and stormwater responsibilities.
• ABSA (Aguas Bonaerenses SA): State-owned water and sewerage utility serving the Buenos Aires Province interior. Comparable to OSSE as a provincial-level public water operator with similar customer-base dynamics and capex-driven network expansion mandates.
• ASSA (Aguas Santafesinas SA): Santa Fe provincial water and sewerage utility. Directly comparable as another Argentine provincial public water utility with similar regulatory and operational structure to OSSE.
• AYSAM (Aguas y Saneamiento Mendoza): Mendoza provincial water and sanitation operator. Comparable as a state-owned Argentine utility managing potable water, sewerage, and irrigation-related infrastructure for a major provincial city.
