- Esval S.A. is a Chilean regulated water and sanitation utility company primarily engaged in the production, treatment, and distribution of potable water, as well as the collection, treatment, and final disposal of residential and industrial wastewater. Founded in 1977 and headquartered in Viña del Mar, Chile, the company operates under long-term sanitary concession contracts, serving residential, commercial, industrial, and public sector customers throughout the Valparaíso Region and, through its primary operating subsidiary Aguas del Valle S.A., the Coquimbo Region. The company is majority-controlled by the Ontario Teachers' Pension Plan through its dedicated infrastructure and sanitary investment vehicles.
The company's core operations are structured across comprehensive water cycle segments, offering a systematic portfolio of products and services that includes raw water extraction and catchment from surface and groundwater sources; drinking water purification, filtration, disinfection, and fluoridation across specialized water treatment plants; pressurized potable water storage, transmission, and distribution through urban distribution networks; sanitary sewerage collection, lifting, and conveyance infrastructure; domestic sewage and wastewater treatment utilizing activated sludge processes, biological filtration, and authorized submarine outfall discharge systems; industrial liquid waste (RILES) control, chemical sampling, and regulatory compliance monitoring; residential and commercial water meter installation, maintenance, calibration, and automated reading; sanitary connections, reconnections, and hydraulic infrastructure engineering; and technical consulting, laboratory water quality analysis, and non-regulated infrastructure maintenance services.
In recent developments, Esval S.A. has intensified its multi-year capital expenditure program dedicated to structural drought mitigation, climate change adaptation, and water security across central Chile. The company has advanced critical infrastructure projects, including the expansion and operational optimization of the Los Aromos-Concón reversible water conveyance pipeline system, capacity and technological upgrades at the Concón drinking water production plant, and the drilling and interconnection of new deep-water extraction wells in the Aconcagua basin. In operational strategy, Esval S.A. has consolidated joint water management agreements with agricultural supervisory boards (Juntas de Vigilancia) to safeguard urban water supply, while executing domestic corporate bond issuances and refinancing programs in the Chilean financial market to fund infrastructure modernization, expand wastewater treatment capacity, and deploy advanced digital telemetry and network pressure management systems aimed at reducing non-revenue water losses.
