Hidrosan

What Hidrosan does

Hidrosan Ingeniería S.A. is a privately held Chilean hydraulic, sanitary, and environmental engineering consultancy founded in 1976 and headquartered in Quilicura, Santiago. The firm designs and delivers water and wastewater treatment infrastructure, industrial effluent (Riles) treatment systems, stormwater management, potable water networks, and pumping stations. Its core technical stack combines civil sanitary engineering with BIM (Building Information Modeling) methodology adopted in 2016 and HIFLOC accelerated decanter technology. The company reports having designed 145 wastewater treatment plants (PTAS) and 115 potable water treatment plants (PTAP), with over 5 million cumulative engineering hours and 1,721 design study participations.

The business operates as a B2B project-based engineering consultancy serving water utilities, municipalities, government agencies, mining/industrial companies, and international consortiums. Revenue is generated through three streams: engineering consulting (studies, conceptual/basic/detail design), construction and turnkey project delivery (Llave en Mano), and operations and technical services (commissioning, training, audits, advisory). Go-to-market is direct enterprise field sales with no channel intermediaries; the firm holds long-standing relationships with major Chilean utilities (Aguas Andinas, Esval, Essbio, ESSAL/Suralis, Econssa, Aguas Patagonia de Aysén) and has executed international projects in Argentina, Colombia, Mexico, and Panama, including a consortium project for Panama City's wastewater treatment plant with Odebrecht and Degremont (Suez group). Operations are supported by an affiliated group ecosystem — Hidrolab (laboratory/testing), Surquímica (treatment chemicals), ESSSI S.A., Aguas Patagonia de Aysén, Tratacal, San Isidro, and others — that vertically integrates parts of the water treatment value chain.

As of 2025, Hidrosan is expanding its service portfolio into hydroelectric power plant design (Centrales Hidroeléctricas) while maintaining its core engineering franchise. The company employs 51-100 people and is privately held under founder/family control with no institutional investors identified.
