Cosersa

What Cosersa does

Cosersa (Contratas y Servicios COSERSA, S.A.) is a Madrid-headquartered drainage and sanitation services firm founded in 1994 and operating as a wholly-owned subsidiary of the VINCI group via ImesAPI and ACS. From its base in Arganda del Rey, the company delivers an integrated portfolio of pocería (drainage) services to residential, commercial, and public-administration customers across the Community of Madrid and four neighboring provinces — Segovia, Toledo, Ávila, and Ciudad Real — covering more than 180 municipalities.

The company's technical capabilities center on specialized sewer and drainage infrastructure equipment, including high-pressure water jetting systems for unclogging, CCTV camera inspection rigs for diagnostic work, milling equipment for pipe restoration, and trenchless rehabilitation technology (manga total / pipe lining) that repairs pipelines without excavation. The service catalog extends into hazardous and non-hazardous waste management with temporary storage facilities, industrial cleaning, asbestos removal, septic tank and separator maintenance, watertightness testing, and environmental compliance advisory. A 24/7 emergency dispatch channel supports urgent callouts. The company operates a direct-service model with no resellers, franchisees, or intermediaries, and relies on local SEO, social media, and direct phone/email contact for demand generation.

Commercially, Cosersa is a professional-services business with quote-based, non-publicly-disclosed pricing. It is structured as a Sociedad Anónima (S.A.) with shares not publicly traded, and inherits the corporate social responsibility, compliance, and capital frameworks of its ImesAPI/ACS/VINCI parents. Headcount is reported in the 11–50 range and the company is described as actively operating with round-the-clock service availability. There is no disclosed revenue, no AI/ML capability, and no independent funding activity, reflecting its status as a regional operating subsidiary within a much larger international infrastructure group.
