What FACSA does

FACSA, legally Sociedad de Fomento Agrícola Castellonense, S.A.U., is a privately held Spanish integrated water cycle management company founded in 1873 and headquartered in Castellón de la Plana. It operates as part of the Nealis (Gimeno Group) Water and Environment division, alongside sister company Sitra and wholly-owned subsidiaries including Waternology (digital water management platform) and Hydrens (advanced engineering). The company delivers the full water cycle — supply, sewerage, wastewater treatment, advanced engineering, water reuse, and environmental stewardship — primarily through multi-decade municipal concessions, supplemented by industrial water services and a growing bioenergy / waste valorization business (biogas, biomethane, composting, biofertilizers, material recovery). It holds ISO 9001, 14001, 45001, 50001, UNE 166002 R&D&I, and ENS certifications.

The core operating model is B2G concession-anchored recurring tariff revenue from municipalities, complemented by professional-services revenue from industrial clients (ceramics, agriculture, manufacturing) and engineering/construction contracts. Customer access is delivered through 9 regional delegations covering Lugo, Madrid, Mallorca, Seville, Toledo, Valencia, Valladolid, and Zaragoza, with 1,500+ employees and 150+ years of operating history. Digital service layers — eOficina (residential self-service portal with iOS/Android apps), extraNET (business and administration portal), Telelectura (remote meter reading), Waternology, and the PERTE-aligned Sinargia solution — provide consumer-facing self-service and B2B digital tools built on GIS and digital-twin infrastructure. The company is also an active participant in EU-funded R&D projects including LIFE REWAINCER, iRAIN, NIAGARA, and ENEDAR, and sponsors major industry forums (DAQUAS, IWA, META).

Revenue mechanics combine regulated water tariffs (monthly for residential customers via eOficina billing, annual for businesses via extraNET) with project-based industrial and infrastructure revenue. The bioenergy / circular-economy vertical — including biogas production, anaerobic digestion upgrading, and biofertilizer recovery from wastewater sludge — represents a deliberate diversification beyond traditional water utility work. Corporate ownership sits within the diversified Nealis / Gimeno Group, with FACSA holding several wholly-owned subsidiaries (Waternology, Hydrens, Sitra) that provide digital, engineering, and innovation capabilities layered onto the core municipal concession business.
